Object Several retrospective studies have demonstrated higher accuracy rates and increased safety for navigated pedicle screw placement than for free-hand techniques; however, the accuracy differences between navigation systems has not been extensively studied. In some instances, 3D fluoroscopic navigation methods have been reported to not be more accurate than 2D navigation methods for pedicle screw placement. The authors of this study endeavored to identify if 3D fluoroscopic navigation methods resulted in a higher placement accuracy of pedicle screws. Methods A systematic analysis was conducted to examine pedicle screw insertion accuracy based on the use of 2D, 3D, and conventional fluoroscopic image guidance systems. A PubMed and MEDLINE database search was conducted to review the published literature that focused on the accuracy of pedicle screw placement using intraoperative, real-time fluoroscopic image guidance in spine fusion surgeries. The pedicle screw accuracy rates were segregated according to spinal level because each spinal region has individual anatomical and morphological variations. Descriptive statistics were used to compare the pedicle screw insertion accuracy rate differences among the navigation methods. Results A total of 30 studies were included in the analysis. The data were abstracted and analyzed for the following groups: 12 data sets that used conventional fluoroscopy, 8 data sets that used 2D fluoroscopic navigation, and 20 data sets that used 3D fluoroscopic navigation. These studies included 1973 patients in whom 9310 pedicle screws were inserted. With conventional fluoroscopy, 2532 of 3719 screws were inserted accurately (68.1% accuracy); with 2D fluoroscopic navigation, 1031 of 1223 screws were inserted accurately (84.3% accuracy); and with 3D fluoroscopic navigation, 4170 of 4368 screws were inserted accurately (95.5% accuracy). The accuracy rates when 3D was compared with 2D fluoroscopic navigation were also consistently higher throughout all individual spinal levels. Conclusions Three-dimensional fluoroscopic image guidance systems demonstrated a significantly higher pedicle screw placement accuracy than conventional fluoroscopy or 2D fluoroscopic image guidance methods.

Object The aim of this study was to investigate the feasibility of integrating three-dimensional rotational angiography (3D-RA) data into a surgical navigation system and to assess its accuracy and potential clinical benefit. Methods The study cohort consisted of 16 patients with 16 intracranial aneurysms who had been scheduled for routine or emergency surgery. Rotational angiography data were exported using a virtual reality modeling language file format and imported into the BrainLAB VectorVision2 image-guided surgery equipment. During 3D-RA the position of the head was measured using a special headframe. The authors also determined the accuracy of 3D-RA image guidance and the clinical benefit as judged by the surgeon, including, for example, early identification of branching vessels and the aneurysm. There was good correspondence between the 3D-RA–based navigation data and the intraoperative vascular anatomy in all cases, with a maximum error of 9° of angulation and 9° of rotation. In eight cases, the surgeon determined that the 3D-RA image guidance facilitated the surgical procedure by predicting the location of the aneurysm or the origin of a branching artery that had been covered by brain tissue and blood clots. Conclusions The integration of 3D-RA into surgical navigation systems is feasible, but it currently requires a new perspective-registration technique. The intraoperative 3D view provides useful information about the vascular anatomy and may improve the quality of aneurysm surgery in selected cases.

Two experiments are reported that contrast egocentric vs. exocentric features of perspective (3D) or plan view (2D) electronic map displays for supporting local guidance and global awareness. Pilots used these displays for a simulated approach to a landing along a curved approach, through a terrain-filled region. The task was simulated on an IRIS visual graphics workstation. In Experiment 1, a rotating vs. fixed-map display was experimentally crossed with a 2D vs. 3D (perspective map) view as 24 pilots were assessed in their ability to maintain the flight path (local guidance) and demonstrate global awareness of surrounding terrain features. Rotating displays supported better flight path guidance in both the lateral and vertical axes, and did not substantially harm performance on the task of recalling the location of terrain features. Map rotation also supported better performance in locating features from an ego-referenced but not a world-referenced perspective. 3D displays provided a slight advantage for lateral guidance but a substantial cost for vertical control, because of the ambiguity with which perspective viewing depicted precise altitude. In Experiment 2, 10 pilots flew with the rotating 2D display, and with an improved version of the rotating 3D display, using color coding to reduce the ambiguity of altitude information. Vertical control improved as a result of the 3D display design improvement, but lateral control did not. Assessment of terrain awareness on a map reconstruction task revealed marginally better performance with the 2D map. The results are discussed in terms of the costs and benefits of presenting information in 3D, ego-referenced format for both local guidance and global awareness tasks.

We hereby describe a minimally invasive resection of a T1 pedicular osteoid osteoma next to the vertebral canal. The patient had an 18-month report of painful radiculopathy. We performed the surgery under 3D imaging guidance using navigation with an all-in-one device. Full procedure irradiation was 1.17 mSv for a 181-picture acquisition. Complete operative time incision to closure was 58 minutes. Despite sparing the vertebral stability without any fixation, the tumor resection was well-margined, thanks to the focused guidance. After surgery, the patient had complete relief of his symptoms at the 6-month follow-up. 3D imaging system coupled to navigation made the procedure safe without consuming time. The single Surgivisio® device allows comfortable 3D minimally invasive spine navigation surgery with the ergonomics of a C-arm.

In this paper, a guidance scheme for achieving all the possible impact angles constraints for 3D engagements is proposed. For a simple and computationally efficient solution, our approach considers proportional navigation based impact-angle constrained guidance. However, the 3D proportional navigation law cannot be directly applied. This paper proposes a guidance strategy in which a 3D problem is divided into two consecutive 2D problems using a temporary target. The missile switches between the two planes using a temporary target. The paper begins with a simple approach and finally proposes a realistic solution. In all the scenarios considered, the guidance scheme achieves the desired impact angles. To further increase its effectiveness, the paper considers pitch constrained impact-angle law that drives the terminal angle of attack to zero. This ensures that the body axis of the missile will be aligned with its velocity vector at the time of impact. The effectiveness of the proposed guidance schemes are systematically verified through numerical simulations considering both kinematic and realistic models with first-order autopilot lag.

SUMMARYA non-holonomic robot with a bounded control input travels in a dynamic unknown 3D environment with moving obstacles. We propose a 3D navigation strategy to reach a given final destination point while avoiding collisions with obstacles. A formal analysis of the proposed 3D robot navigation algorithm is given. Computer simulation results and experiments with a real flying autonomous vehicle confirm the applicability and performance of the proposed guidance approach.

ABSTRACTThis study focuses on the co-operative salvo attack problem of multiple missiles against a stationary target under jointly connected switching topologies subject to time-varying communication delays. By carefully exploring certain features of the typical pure proportional navigation guidance law, a two-stage distributed guidance scheme is proposed without any information on time-to-go in this study to realise the simultaneous attack of multiple missiles. In the first guidance stage, a co-operative guidance law is proposed using local neighbouring communications only to achieve consensus on range-to-go and heading error to provide favourable initial conditions for the latter phase, in which switching topologies and time-varying communication delays are taken into account when obtaining sufficient conditions of consensus in terms of linear matrix inequalities. Then, missiles disconnect from each other and are guided individually by the typical pure proportional navigation guidance law with the same navigation gain to realise salvo attack in the second guidance phase. Finally, numerical simulations are carried out to clearly validate the theoretical results.

Object In recent years, the importance of intraoperative navigation in neurosurgery has been increasing. Multiple studies have proven the advantages and safety of computer-assisted spinal neurosurgery. The use of intraoperative 3D radiographic imaging to acquire image information for navigational purposes has several advantages and should increase the accuracy and safety of screw guidance with navigation. The aim of this study was to evaluate the clinical and methodological precision of navigated spine surgery in combination with the O-arm multidimensional imaging system. Methods Thoracic, lumbar, and sacral pedicle screws that were placed with the help of the combination of the O-arm and StealthStation TREON plus navigation systems were analyzed. To evaluate clinical precision, 278 polyaxial pedicle screws in 139 vertebrae were reviewed for medial or caudal perforations on coronal projection. For the evaluation of the methodological accuracy, virtual and intraoperative images were compared, and the angulation of the pedicle screw to the midsagittal line was measured. Results Pedicle perforations were recorded in 3.2% of pedicle screws. None of the perforated pedicle screws damaged a nerve root. The difference in angulation between the actual and virtual pedicle screws was 2.8° ± 1.9°. Conclusions The use of the StealthStation TREON plus navigation system in combination with the O-arm system showed the highest accuracy for spinal navigation compared with other studies that used traditional image acquisition and registration for navigation.

Im Rahmen einer experimentellen Vergleichsstudie zweier bildwandlergestützter Navigationssysteme wurde die 3D-bildwandlergestützte Navigation mit der 2D-bildwandlergestützten Navigation zur Pedikelschraubenplatzierung am Modell getestet. Neben der Präzision der Bohrungen in einem postoperativen CT wurden Bildqualität, Genauigkeit des 3D-Scans, Planbarkeit und Umsetzung der Bohrungen bewertet und verglichen. Mit der 3D- Bildwandler- Navigation wurden 38 der 40 Bohrungen exakt platziert (95%). Eine Planung wurde durch einen Softwarefehler der Alpha-Version auf dem Monitor falsch wiedergegeben. Bei einer weiteren Bohrung wurde der Bohrer verkantet, wodurch Bildschirmdarstellung und Realität voneinander abwichen. Daher kam es in einem Fall zu einer lateralen Perforation der Kortikalis im Bereich des Pedikels, im anderen zu einer kaudalen Perforation. Mit der 2D- Bildwandler- Navigation konnten alle 40 Schrauben ohne Pedikelperforation platziert werden. Zwei dieser Schrauben wurden durch die ventrale Kortikalis gebohrt. Beide Verfahren überzeugten durch hohe Präzision und Zuverlässigkeit. 3 der 4 Fehlplatzierungen waren Anwender einer Software bedingt. Eine optimierte Software und verbesserte Instrumente werden diese Fehlerquote weiter reduzieren. Voraussetzung für die 2D-bildwandlergestützten Navigation sind eine gute Bildqualität sowie normale anatomische Gegebenheiten für standardisierte Projektionen. Die neue 3D-bildwandlergestützter Navigation kombiniert die Vorteile der 2D-bildwandlergestützter Navigation und der CT- basierten Navigation mit einer Verringerung der Strahlenbelastung durch den Wegfall des präoperativen CT`s und somit der Einsatzmöglichkeit im akuten Notfall sowie nach intraoperativen Repositionsmanövern. Da kein Matching erforderlich ist, wird insbesondere bei traumatischer Verletzung oder tumorbedingter Veränderung der dorsalen Wirbelstrukturen ein großer Vorteil zur CT- basierten Navigation erwartet. Aufgrund der universellen Einsatzmöglichkeiten eines Bildwandlers wird für diese neue Technologie ein breites Indikationsspektrum angenommen.
An experimental study to compare 2D- and 3D- Computer-Assisted Fluoroscopic Navigation for pedicle screw placement. Each system was evaluated by a post-operative CT and included the comparison of the palpation of the pedicular canal, the image quality and the accuracy of planning and performance. For this purpose 40 screws have been set to 9 models of lumbar spine. Using the 3D-flouroscopy based navigation 38 from 40 (95%) drillings were placed correctly. One mistake was caused by an error of the navigation-software. The second mistake was due to a drilling mistake, the drill was not shown correctly on the monitor because the drill has been canted. Using the 2D-flouroscopy based navigation all screws could be placed correctly at the pedicle, but two times the corpus has been perforated to ventral. Both techniques are precise and reliable. 3 out of 4 mistakes were caused by incorrect handling the instrument. The other mistake happened because of a software-error. If the software and the instruments will be optimised, the amount of mistakes will be reduced in the future. In case of the 2D-flouroscopy based navigation sufficient image quality, normal anatomical structures and defined projections are required. The new 3D-flouroscopy based navigation combines the benefit of 2D-flouroscopy based navigation and CT-based navigation by reducing the radiation exposure and the preoperative planning time. Therefore, this technique is suitable for use in an emergency or intraoperative repositions. Because no matching-procedure is necessary for CT-based navigation, we expect advantages especially in therapy of traumatic injuries or changes at the dorsal structures of spine caused by tumour. Furthermore, the use of fluoroscopic based navigation extends the range of applications/the spectrum of indication for this new technology.

Le carcinome hépatocellulaire est le principal cancer primaire du foie. Les procédures d’ablation thermique par voie interstitielle constituent un type de traitement curatif de ce cancer. Ces méthodes ne permettent pas toujours, de par leur nature physique (radio fréquence, micro-onde, laser, cryothérapie), de générer une ablation conformationnelle pour un volume tumoral donné. Dans certains cas, cela peut entraîner l’ablation d’un volume important de tissus non tumoraux. L'utilisation d'une sonde interstitielle ultrasonore disposant d’un transducteur avec de nombreux éléments indépendants, capable de générer des ultrasons focalisés de haute intensité (HIFU), permettrait théoriquement de lever cette limitation. D’autre part, le nombre élevé d’éléments permettrait également de disposer de capacités d’imagerie. Les travaux présentés dans cette thèse ont donc d’abord porté sur la conception du transducteur associé à ce type de sonde. Un design particulier a été proposé spécifiquement pour le traitement d’une tumeur de 4 cm de diamètre. S’est ensuite posé la question de la stratégie de planification du traitement à adopter pour obtenir une lésion la plus conformationnelle possible. Différentes stratégies ont été évaluées par simulations numériques. Toutes ont présentés des caractéristiques semblables tant en termes de conformation que de temps de traitement total. La focalisation ultrasonore s’est avérée en elle-même suffisante pour générer un traitement conformationnel. Finalement, une plateforme robotique a été développée pour le pilotage de prototypes de sondes ultrasonores interstitielles bimodales, aussi bien en mode imagerie qu’en mode thérapie. Cette plateforme a permis de réaliser in vitro, les planifications de traitement automatiques de plusieurs fantômes de tumeurs, en se basant sur la reconstruction ultrasonore 3D issue de l’imagerie échographique obtenue in situ par les sondes ultrasonores. En revanche, en mode thérapie les prototypes de sondes n’ont pas atteint leurs spécifications et n’ont pas réussi à générer des lésions thermiques dans des tissus hépatiques in vitro. La modularité de la plateforme robotique a rendu possible son utilisation avec un système de thérapie ultrasonore différent, à la fiabilité éprouvé. Avec ce système, la planification automatique du traitement, ainsi que l’exécution du traitement HIFU associé, ont pu être effectué in vitro avec succès par la plateforme
Hepatocellular carcinoma is the most common primary cancer of the liver. Interstitial thermal ablation procedures constitute a type of curative treatments for this cancer. Given the physical nature of the phenomenon used to modify temperature (radio frequency, micro wave, laser, cryotherapy), those methods may not be able to generate a conformal treatment for a given tumor shape. In some cases, this limitation may induce the thermal ablation of a large volume of non-tumor tissues. The use of an ultrasound interstitial probe mounted with a multi-element transducer capable of generating high intensity focused ultrasound (HIFU) may theoretically help to overcome this limitation. Also a transducer with an important number of elements may also provide in situ imaging. As a first step, the design of a transducer for interstitial ultrasound probe was studied. A specific configuration has been proposed for the treatment of tumors with a diameter of 4 cm. The question of the treatment planning method to adopt to reach an optimal conformal treatment has been then addressed by comparing numerical simulations of different strategies. All strategies were sufficiently conformal and none presented real assets compared to the others. Ultrasound focusing in itself provided the desired conformal thermal ablation. Finally, a robotic platform was developed for driving interstitial dual mode ultrasound probes, both in imaging and in therapy mode. This platform allowed the automatic treatment planning of in vitro tumor mimic phantoms, based on 3D ultrasound reconstruction from the B mode images obtained in situ by the interstitial probe. However, in therapy mode, the probes did not reach their specifications and did not manage to create thermal lesions in in vitro liver tissue sample. The modularity of the robotic platform allowed driving a different HIFU system, which was more robust. With this system, the platform managed to perform with success an automatic treatment planning and then the associated HIFU treatment in in vitro tissue sample

Les travaux présentés dans cette thèse contribuent aux systèmes de localisation pour un robot mobile en utilisant la stéréovision. Ces travaux s'inscrivent dans le cadre d'une collaboration entre le LORIA-INRIA de Nancy et le laboratoire SeT de l'UTBM. L'approche proposée est décomposée en deux étapes. La première étape constitue une phase d'apprentissage qui permet de construire un modèle 3D de l'environnement de navigation. La deuxième étape est consacrée à la localisation du véhicule par rapport au modèle 3D. La phase d'apprentissage a pour objectif de construire un modèle tridimensionnel, à partir de points d'intérêt pouvant être appariés sous différentes contraintes géométriques (translation, rotation, changement d'échelle) et/ou contraintes de changements d'illumination. Dans l'objectif de répondre à toutes ces contraintes, nous utilisons la méthode SIFT (Scale Invariant Feature Transform) permettant des mises en correspondance de vues éloignées. Ces points d'intérêt sont décrits par de nombreux attributs qui font d'eux des caractéristiques très intéressantes pour une localisation robuste. Suite à la mise en correspondance de ces points, un modèle tridimensionnel est construit, en utilisant une méthode incrémentale. Un ajustement des positions est effectué afin d'écarter les éventuelles déviations. La phase de localisation consiste à déterminer la position du mobile par rapport au modèle 3D représentant l'environnement de navigation. Elle consiste à apparier les points 3D reconstruits à partir d'une pose du capteur stéréoscopie et les points 3D du modèle. Cet appariement est effectué par l'intermédiaire des points d'intérêt, issus de la méthode d'extraction SIFT. L'approche proposée a été évaluée en utilisant une plate-forme de simulation permettant de simuler un capteur stéréoscopique, installé sur véhicule naviguant dans un environnement 3D virtuel. Par ailleurs, le système de localisation développé a été testé en utilisant le véhicule instrumenté du laboratoire SeT afin d'évaluer ses performances en conditions réelles d'utilisation.

We present an interactive guidance and navigation system that assists users in acquiring pictures for image based 3D modeling. To reconstruct an object’s 3D model, users follow our instruction to take a set of images for an object in different angles; we therefore calculate their relative viewing positions and spare point cloud data using structure from motion technique. After we obtain sufficient number of images, we use Patch-based Multi-View Stereo (PMVS)[1] software to generate dense point cloud data. When displaying dense point cloud, we provide user an interface to eliminate those noise data points yielded from background construction or re-projection errors. Afterwards we reconstruct surface mesh as output. Our system provides informative message for failure while calculating camera poses and helps user how to resolve those problems. Furthermore, we assess the quality of camera poses reconstruction and generated point cloud to reveal the lack of angles for captured images and guides user to remedy those information.

The IT technology has been well developed for current generation. The popularity of communication has promoted the application of IT and the navigation systems are used by more population. The house selling companies have provided the guide system so customer can look up the space pattern through internet to save the transportation time. Some big enterprises and education may be lack of navigation system and guide system therefore can not provide visitors a better space guidance service. In this study the GPS and Wi-Fi are used to construct Space Guidance System for visitors to easily navigate to target. This study will use 3D technology to build 720 degrees animations for selected points so users can look the views of new environments through browser. The ER Model, SQL Server, ASP.net, ODBC, PDA and Windows environment are used to develop “Space Navigation and Guidance System” which includes modules such as ‘Organization Management’, ‘Faculty Management’, ‘Space Management’,‘Schedule Management’, ‘Activity Management’ and ’Space Guidance’. This study will integrate space and faculty data. When related data of visited person, such as name, phone number, extension number, fax number, email, faculty number or room number, is keyed-in, the system will show the path from start point to destination point. The system will use GPS outside the building and use Wi-Fi to navigate customers inside the building. When visited person has multiple offices or in lecture or meeting, system can detect and provide user to choose appropriate target. The system will guide visitor to selected destination to save groping time for visitor and promote space service quality as well as enterprise image. When visitors want to attend some activity such as conference or meeting, the system can direct them to scene of selected activity. Through the help of 3D guidance, user can view the 720 degrees animation to familiar interesting points. This will help us to know new environment easily and significantly promote the organization image.

Current approaches for the surgical correction of craniosynostosis are highly dependent on surgeon experience. Therefore, outcomes are often inadequate, causing suboptimal esthetic results. Novel methods for cranial shape analysis based on statistical shape models enable accurate and objective diagnosis from preoperative 3D photographs or computed tomography scans. Moreover, advanced algorithms are now available to calculate a reference cranial shape for each patient from a multi-atlas of healthy cases, and to determine the most optimal approach to restore normal calvarial shape. During surgery, multiple technologies are available to ensure accurate translation of the preoperative virtual plan into the operating room. Patient-specific cutting guides and templates can be designed and manufactured to assist during osteotomy and remodeling. Then, intraoperative navigation and augmented reality visualization can provide real-time guidance during the placement and fixation of the remodeled bone. Finally, 3D photography enables intraoperative surgical outcome evaluation and postoperative patient follow-up. This chapter summarizes recent literature on all these technologies, showing how their integration into the surgical workflow could increase reproducibility and reduce inter-surgeon variability in open cranial vault remodeling procedures.

With the dramatic progress of medical imaging modalities and growing needs for high-resolution intraoperative imaging in minimally invasive surgery, hybrid operative room (OR) has been developed as a powerful tool for different surgical scenarios. Under the guidance of high-definition cone beam CT (CBCT), an electromagnetic navigation bronchoscopy (ENB)-based marker implantation and subsequent localization of the pulmonary nodules can be implemented within a hybrid OR. Furthermore, the unparalleled real-time imaging capabilities and the ability to perform multiple tasks within the hybrid OR can facilitate image-guided single-port video-assisted thoracic surgery (iSPVATS), increasing the precision and improving outcomes of the procedure. With the help of a hybrid theatre, catheter-based thermal ablation can provide a safer and less invasive treatment option for select patient groups with early-stage non-small cell lung carcinomas (NSCLC) or metastases. In the future, the combination of hybrid operating room and other inspiring innovative techniques, such as robotic bronchoscopy, 3D-printing, natural orifice transluminal endoscopic surgery (NOTES) lung surgery could lead to a paradigm shift in the way thoracic surgery is conducted.
