Evaluation of Deformable Image Registration-Based Contour Propagation From Planning CT to Cone-Beam CT
PURPOSE We evaluated the performance of organ contour propagation from a planning computed tomography to cone-beam computed tomography with deformable image registration by comparing contours to manual contouring. MATERIALS AND METHODS Sixteen patients were retrospectively identified based on showing considerable physical change throughout the course of treatment. Multiple organs in the 3 reg...

متن کاملDoes cone-beam CT alter treatment plans? Comparison of preoperative implant planning using panoramic versus cone-beam CT images
PURPOSE The present study was performed to compare the planning of implant placement based on panoramic radiography (PAN) and cone-beam computed tomography (CBCT) images, and to study the impact of the image dataset on the treatment planning. MATERIALS AND METHODS One hundred five partially edentulous patients (77 males, 28 females, mean age: 46 years, range: 26-67 years) seeking oral implant...
متن کاملMedicolegal Issues Related to Cone Beam CT
The introduction of cone beam computed tomography into dentistry, and particularly into private offices, has raised a number of medicolegal issues. Among the issues raised are who may own and operate the machines, for what purposes should the machines be used, how broadly or narrowly should the field be collimated, does the full volume need to be interpreted and, if so, by whom? For images inte...
متن کاملRespiratory correlated cone beam CT.
A cone beam computed tomography (CBCT) scanner integrated with a linear accelerator is a powerful tool for image guided radiotherapy. Respiratory motion, however, induces artifacts in CBCT, while the respiratory correlated procedures, developed to reduce motion artifacts in axial and helical CT are not suitable for such CBCT scanners. We have developed an alternative respiratory correlated proc...
