Deformable registration for image-guided radiation therapy.
Ths paper examines several applications of deformable registration algorithms in the field of image-guided radiotherapy. The first part focuses on the description of input and output of deformable registration algorithms, with a brief review of conventional and most current methods. The typical applications of deformable registration are then reviewed on the basis of four practical examples. Th...
متن کاملEvaluation of deformable image registration in HDR gynecological brachytherapy
Introduction: In brachytherapy, as in external radiotherapy, image-guidance plays an important role. For GYN treatments it is standard to acquire at least CT images and preferably MR images prior to each treatment and to calculate the dose of the day on each set of images. Then, the dose to the target and to the organs at risk (OAR) is calculated with worst case scenario from I...
متن کاملA contour-guided deformable image registration algorithm for adaptive radiotherapy.
In adaptive radiotherapy, deformable image registration is often conducted between the planning CT and treatment CT (or cone beam CT) to generate a deformation vector field (DVF) for dose accumulation and contour propagation. The auto-propagated contours on the treatment CT may contain relatively large errors, especially in low-contrast regions. A clinician's inspection and editing of the propa...
متن کاملAutomatic Deformable Mr-ultrasound Registration for Image-guided Neurosurgery
Registration of preoperative MR images and Ultrasound images are used for the purpose of accuracy in detecting the tumor. Image Guided Neurosurgery Systems (IGNS) can be used to track surgical tools with respect to the preoperative Magnetic Resonance (MR) images, brain tissue movement during surgery invalidates the image-topatient mapping and thus reduces the effectiveness of using preoperative...
متن کاملHow does CT image noise affect 3D deformable image registration for image-guided radiotherapy planning?
PURPOSE To measure the sensitivity of deformable image registration to image noise. Deformable image registration can be used to map organ contours and other treatment planning data from one CT to another. These CT studies can be acquired with either conventional fan-beam CT systems or more novel cone-beam CT techniques. However, cone-beam CT images can have higher noise levels than fan-beam CT...
