Santos, Pedro. « Patch based 3D reconstruction of the liver surface from laparoscopic videos ». Master's thesis, Universidade de Aveiro, 2013. http://hdl.handle.net/10773/11773.
Texte intégralEndoscope is commonly used in Laparoscopic surgery. It allows to the doctor to perform the surgery without opening a cavity. Therefore, it allows the surgeon to perform smaller incisions and consequently diminish the risk of infection. An investigation regarding the reconstruction of the liver surface from a sequence of images obtained from an endoscope video has been done by the Vision Institute of TUHH, in cooperation with the Medical Center Hamburg-Eppendorf. The goal of this paper is to optimize that reconstruction. Previous works in the institute allowed, using matlab functions, to obtain a first reconstruction. Having the matrices of the transformations between cameras and the reconstructed points in 3D, the goal is to optimize that using a patch based 3D reconstruction. The method consists of the construction of a patch for every point and trying to find a good normal for the patch. Some tools are used for the optimization like normal cross correlation that is the similarity function used for obtaining the match of the corresponded 2D windows in different cameras, and a nonlinear optimization method to look for the best normal who gives the best match between the windows. The main objective is to evaluate this method and draw conclusions about its utility and viability: can this method be used for the optimization in the case of the endoscope video of a liver surface.

Texte intégralRecovering dense 3D information from intra-operative endoscopic images together with the relative endoscope camera pose are fundamental blocks for accurate guidance and navigation in image-guided surgery. They have several important applications, e.g., augmented reality overlay of pre-operative models. This thesis provides a systematic approach for estimating these two pieces of information based on a pure vision Simultaneous Localization And Mapping (SLAM). We decouple the dense reconstruction from the camera trajectory estimation, resulting in a system that combines the accuracy and robustness of feature-based SLAM with the more complete reconstruction of direct SLAM methods. The proposed solutions in this thesis have been validated on real porcine sequences from different datasets and proved to be fast and do not need any external tracking hardware nor significant intervention from medical staff. The sole input is video frames of a standard monocular endoscope

Laparoscopy has been wildly applied in kinds of surgeries, becasuse of its minimal invasion, less trauma, quick recovery, shorten surgery time and time to stay in hospital. But its operation requires experienced skill and good hand-eye coordination, therefore it''s a long time for a graduating medical student to become eligible for being certified as asurgical specialist. With our own laparoscopic input devices and computergraphics techniques, a laparoscopic surgical simulator will be designed to train the surgeon''s operation skill on laparoscopy. The research is based on personal computer. In medical image 3D reconstruction, Marching Cubes Algorithm is adopted to generate 3D surfacemodel of the contigous medical images, and the model will be used in the surgical simulation system. In this system, image transmission is completed with image compression and network communication, also the camera motion is controlled by the voice.

Laparoscopic surgery provides many advantages, such as reducing pain, minimizing damage to healthy tissues, and faster recovery time. It also has some limitations mainly caused by inaccurate depth perception, limited field of view and more execution time required. Recently, 3D imaging technology had been applied to laparoscopic surgery. However, it brought some visual fatigue and discomfort during or after surgery. In this study, two tasks, peg transferring (more depth perception needed) and circle tracing (less depth perception needed), were used to be performed with two display conditions (2D and 3D) by students from different universities. The result indicated that performance of peg transferring was better in 3D compared with 2D imaging, as it showed lower movement time and errors with 3D imaging. On the other hand, the performance of circle tracing showed the reverse because participants performed worse in 3D imaging. However, no significant difference on decrease of CFF and mental workload was observed. The result from the subjective questionnaires showed performing tasks with 3D images induced more visual fatigue and discomfort. From the analytical results in present study, it can be concluded that 3D imaging had better performance for tasks that require more depth perceptions, but worse when the tasks require less depth perception. Even if the current developments in 3D technology had interesting promises, it is still premature to say the technology provides perfect image quality which is free of limitations. Therefore, to enhance the performance of laparoscopic surgery, it is worth looking forward to 3D imaging technology that can provide a better image quality with minimum side effects.

The study integrated virtual reality technology and developed a system which would reconstruct three-dimensional (3-D) models and provide highly accurate volume estimations from selected areas of medical images. After development processes, we devised an experiment to test and verify the results of 3-D reconstruction and volume estimations. The experiment result showed that the appearances of reconstruction models were very similar to the real ones, and the value of volume estimations were very close to the values evaluated by drainage. After verifying the accuracy of volume estimations, another clinical experiment was implemented. Three kinds of tumor volume estimations, including the single maximum diameter method, ellipse method and our 3-D integration method, were performed and the relationship of these volume estimations among associated cervical cancer prognostic parameters was evaluated.This study found that the parameters of lymph nodes metastasis, parametrial involvement and tumor differentiation are volume dependent. 3D-tumor volumetry showed superior discrimination of these parameters than current single maximum diameter evaluation suggesting its potential as a rapid method for initial prediction of prognostic factors in cervical cancer. In this study, a virtual reality-based simulator system was developed for extensive laparoscopic surgery training. The purpose of this study is to assess the feasibility of virtual reality-based laparoscopic gynecology simulation system. Ten healthy, non-disabled volunteers were recruited. The surgical procedure is a process of tubal sterilization by cauterization. Volunteers followed the training procedure fifteen trials in the first test and retest respectively. Stable performances were obtained after about eight trials for all subjects. The results of this study indicate that the system is stable and the system has fair high test-retest reliability. Another thirty two non-disabled volunteers were recruited for participating in the different signal feedback experiment. The purpose of this experiment is to assess the influence of text, sound and lateral view cues on the manipulation performance in the system. The average of task time, error times and clip times are the parameters used to evaluate the manipulation performance. It can be concluded that all of the text, sound and lateral view cues are significant cues of manipulation performance of this simulation system. Finally, we employed another laparoscopic gynecology simulating device with force feedback functions, and devised a new function of changing the field of view of laparoscope camera for enhancing the capability of this simulation system. The feasibility and different signal feedback experiments were executed again. The results of the experimants indicate that the new system is stable and has fair high test-retest reliability. Because of the effects of the functions and design of this experiment, the experiment results shows that the new functions, including both force feedback and changing the field of view of laparoscope camera, are not significant cues of manipulation performance of this simulation system.

Laparoscopic surgery is slowly replacing the traditional invasive surgeries due to the benefits, including speedy recovery time, and reducing the chance of complications. But this surgical approach also limits the surgeons' depth perception and vision. They need to spend more time to complete the operation, thus leading the surgeons to have higher mental workloads. This research, through the usage of EEG and NASA TLX analyzed 12 participants who performed tasks with different depth perception to understand the effect of 2D and 3D images on one’s mental workload. This experiment uses Alpha brainwave and blink rate as the index for mental pressure while the Gamma wave is used as the index for concentration. Prior to the start of the experiment, participants were asked to rest for 2 minutes to calibrate the brainwave signals from unwanted noises. Afterwards, participants were asked to wear the Muse headband and to stand 2 meters away from the 3D monitor while performing the two tasks (peg transfer and circle tracing). From the brainwave result, 3D display results in higher Alpha wave activity, blink rate, and lower Gamma wave activity. In general, the participants feel more relaxed and have lower concentration level in the 3D environment. The NASA TLX survey results also show that stereoscopic vision can be helpful in lowering mental workload and frustration. Due to the result of both subjective and objective analysis, we conclude that the 3D display technology provides helpful depth perception and direction, thus lowering the mental demand of the participants during the completion of the tasks. However, 3D displays do not produce good enough images, therefore causing eye-fatigue to the participants.
