Full textOptical Coherence Tomography (OCT) imaging is promising in decision making during Percutaneus Coronary Interventions {PCI) procedures, including evaluating controversial plaque lesions, assessing stent implantation, and surveying stent-related vascular injury. Thus, OCT has potential to guide interventional cardiologists throughout the stent implantation procedure, impacting on planned interventional strategy. In addition, OCT is the most novel image technology to predict stent edge dissection for patients with non-ST-segment elevation ACS, enabling risk stratification of patients who are at a higher risk of this complication. Large-scale randomized trials are now warranted to assess whether OCT results and guidance during de procedure improve long-term clinical outcomes of PCis

Full textThe treatment of cardiovascular diseases requires navigating guidewires and catheters through the vascular anatomy. This task can be very challenging and often results in prolonged procedures where both the patient and clinician are exposed to X-ray radiation.To address this limitation, this manuscript proposes two main systems: one that enhances fluoroscopic images and another that autonomously navigates surgical tools. The first is essentially an assistance system, overlaying the classical fluoroscopic images with information about the anatomy and about the predicted outcome of clinician’s actions before they are performed. The second is a Deep Reinforcement Learning controller which aims to autonomously perform the procedure by controlling an endovascular surgical robot. Currently, these robots function only as leader-follower devices and are unable to provide additional support to the caregiver during the procedure.In tests conducted on a phantom in the context of a user study, the enhanced fluoroscopic system reduced intervention time by 56%. The autonomous controller achieved, in a simulated environment, a success rate of over 95% on realistic anatomies, even when tested on geometries with characteristics completely different from the training models

Full textTranscranial Magnetic Stimulation is a noninvasive method which consists in positionning a magnetic coil on the head of a patient, in order to deliver an electric stimulation to the cortex. Its efficiency has been demonstrated in the case of depression and studies are currently being conducted for other pathologies. Even if this technique is very promising, it is not yet widely used because of the manual gesture which prevents from rigorously evaluating this means of treatment, as well as considering it as a clinical routine. In order to provide a better development of this technique, a dedicated robotic system has been designed whose first prototype is currently being finalized and is meant to enable an automated and safe displacement of the coil on the scalp of the patient. We have proposed here the design of an original and fitted kinematic architecture allowing to safely position the coil, a method for the following of predefined coil trajectories which compensates for the potential head movements, and finally a method to ensure the control of the force exerted by the coil on the head of the patient

Full textThe original properties of nanoparticles make them extremely attractive in the field of oncology. In fast, gold nanoparticles coated by macrocyclic ligands allow imaging and therapy with only one object. Therefore, multifunctional platforms are very promising for image-guided therapy, winch constitutes an important step towards personalization of treatment. This consists of stimulating the therapeutic activity of the nanoparticles when their accumulation is high within the tumor zone and low in healthy tissues. A higher selectivity of the treatment is therefore expected. Biodistribution study by SPECT/CT has shown free circulation, renal elimination and a moderate retention by the liver of the nanoparticles. However, this retention is not due to the opsonisation processus. The MRI study of rats' brain carrying a gliosarcoma has shown an accumulation of nanoparticles Au@FADOTAGA-Gd in the tumor. Moreover, the co-labeling of these nanoparticles by Ge and 64Cts2+was successfully performed. As a result, PET/MRI images, a much researched combination but rarely achieved, were acquired on the same animal alter intravenous injection of the co-labeled nanoparticles. The radiosensitizing character of nanoparticles Au@TADOTAGA was confirmed by the follow up of tumor growth alter a treatment by MRT (microbeam irradiation) 15 minutes after intratumoral injection of nanoparticles. The therapeutic gain of this treatment has been validated by MRT 24 hours after intravenous injection of nanoparticles to rats carrying gliosarcoma (radioresistant tumor in radiosensitive organ)

Full textThe reference treatment for locally advanced cervical carcinomas relies on chemoradiotherapy and brachytherapy (BT). The radiotherapy (RT) is based on a planning made on a single scanner and on the delivery of the treatment. During the treatment, the clinical target volume (CTV) position may change and hamper the precision of the dose delivery, thus, increasing the risk of recurrence and toxicity. The aim of the thesis is the development of new adaptive radiation therapy (ART) strategies in order to take in account the per-treatment anatomical deformations. These approches will have to rely on image processing tools such as deformable image registration (DIR) and data mining to extract the information from the images acquired at the planning and during the treatment. The work of this thesis has led to the definition of two new ART strategies: (1) an evolutive planning library that can be enriched by new per-treatment anatomies; (2) a modeled library based on a population analysis at the time of planning. Finally, in the context of delivered dose estimation, a biomechanical based DIR method is proposed to map the anatomy of the BT, with applicator, toward the anatomy of RT, without applicator. This method is compared to open access and commercially available DIR methods. The geometrical evaluation, show that the proposed adaptive strategies allow to insure a good coverage of the CTV for all the patients while limiting the irradiation of the healthy organs. Such strategies may improve the clinical outcome of the patients

Full textRadiation therapy is nowadays one of the most common treatments in the fight against cancer, in spite of its lack of selectivity in tissue destruction. A better selectivity is expected to be achieved when radiosensitizing nanoparticles are used for enhancing the dose effects of the ionizing radiations. The aim of this PhD work is to synthesize and to characterize multifunctional gold nanoparticles (Au@DTDTPA), detectable in vivo through various techniques such as by X-ray imaging, MRI and y-ray scintigraphy, as well as evaluating their capability to be used as image-guided radiosensitizing agents to treat tumors. The biodistribution of the Au@DTDTPA nanoparticles in healthy rats is monitored by X-ray imaging, MRI and y-imaging and shows that they freely circulate in the blood flow without being detected by the immune system and that they are excreted by the urine through renal filtration. In the case of cerebral tumor bearing rats, the gold nanoparticles accumulate temporarily in the tumoral zone before being eliminated by urine. The radiosensitizing behavior of the Au@DTDTPA nanoparticles was demonstrated in vitro using the comet assay, by quantifying the increase of DNA strand breaks caused to nanoparticle-labeled U87 human glioblastoma cells, compared to the unlabeled cells. The capability of these nanoparticles to increase the effects of ionizing radiations was then shown in vivo with rats bearing aggressive bone tumors (osteosarcoma). When an intratumoral injection of Au@DTDTPA nanoparticles was performed before the tumor irradiation, the rats' median survival time was prolonged and the tumor reappearance was differed, compared to the control groups. The MRI monitoring of the accumulation of the Au@DTDTPA nanoparticles on the tumoral site of gliosarcome 9L bearing rats after intravenous injection permitted the irradiation by X-ray microbeams when the nanoparticles distribution was favorable. The median survival time of nanoparticle treated rats was indeed extended compared to the control groups. This work therefore showed the possibility to use Au@DTDTPA nanoparticles combining imagery and therapy features as image-guided radiosensitizing agents to treat tumors. The increase of the retention time of Au@DTDTPA nanoparticles within the tumor site could prolong threated rats’ lifespan

Full textThis thesis deals with the compensation of brain deformations which occur during neurosurgical procedures. Neuroavigation systems have become a very attractive tool in surgical planning and procedure. However, the accuracy and usefulness of such systems are limited in presence of soft-tissue deformations. In neurosurgery, this phenomenon is called ``brain shift''. At present, the compensation of the ``brain shift'' is one of the most important challenge in image-guided neurosurgery. The contribution of this thesis deals with non rigid registration between intraoperative ultrasound images and preoperative magnetic resonance images (MRI). In order to achieve this multimodal non rigid registration, several processes are described in this manuscript. First, a new method for 3D reconstruction of freehand ultrasounds is presented. Based on the incorporation of the probe trajectory during the interpolation step, this approach allows to improve the reconstruction quality. Then, a study on the non local means denoising filter is proposed. This contribution is twofold: the improvement of the denoising quality with a reduction of the computational time, and the adaptation of this filter to the speckle. Finally, a new framework for multimodal registration of ultrasound images and MRI is presented. Based on the probability for a voxel to be include in a hyperechogenic structure, this framework allows to achieve a robust and accurate registration. All these processes are integrated into an automatic workflow to compensate for brain shift. First results obtained on four real data sets are presented
