An Evaluation of Tetrahedral Mesh Generation for Non-Rigid Registration of Brain MRI
In this paper, we assess the impact of mesh generation on Non-Rigid Registration of brain MR images. The solution accuracy and the speed of finite element solvers depend on how well the underlying mesh approximates the surface of the biological object (fidelity) and how well the elements of this mesh are shaped (quality). Fidelity and quality, however, are two contradicting requirements, as inc...
متن کاملCompensation of brain shift during surgery using non-rigid registration of MR and ultrasound images
Background: Surgery and accurate removal of the brain tumor in the operating room and after opening the scalp is one of the major challenges for neurosurgeons due to the removal of skull pressure and displacement and deformation of the brain tissue. This displacement of the brain changes the location of the tumor relative to the MR image taken preoperatively. Methods: This study, which is done...
متن کاملNew Pseudo-CT Generation Approach from Magnetic Resonance Imaging using a Local Texture Descriptor
Background: One of the challenges of PET/MRI combined systems is to derive an attenuation map to correct the PET image. For that, the pseudo-CT image could be used to correct the attenuation. Until now, most existing scientific researches construct this pseudo-CT image using the registration techniques. However, these techniques suffer from the local minima of the non-rigid deformation energy f...
متن کاملAdaptive Mesh Refinement for Non-rigid Registration of Brain Mri
The objective of tumor resection during neurosurgery is to remove as much as possible of the tumor tissue with the minimum damage to the neighboring brain structures. This goal is complicated by intraoperative shift of the brain tissue: pre-operative images become inaccurate. Open Magnetic Resonance (MR) scanners facilitate low-quality image acquisition during the surgery. Non-rigid registratio...
متن کاملPseudo-CT Generation from Magnetic Resonance Imaging by fuzzy look up table algorithm
Introduction: Despite growing interest in the use of magnetic resonance imaging (MRI) in the external radiotherapy design process (RT), Computer Tomography (CT) remains a gold standard and is regarded as a basic imaging modality in radiotherapy. MRI shows the high contrast in soft tissues without any radiation exposure to patients. As a result, MRI is used in functional tissue ...
