Evaluating positional accuracy using megavoltage cone-beam computed tomography for IMRT with head-and-neck cancer
Accurate dose delivery is essential for the success of intensity-modulated radiation therapy (IMRT) for patients with head-and-neck (HN) cancer. Reproducibility of IMRT dose delivery to HN regions can be critically influenced by treatment-related changes in body contours. Moreover, some set-up margins may not be adaptable to positional uncertainties of HN structures at every treatment. To obtai...
متن کاملEvaluating the Distance between Posterior Teeth and the Maxillary Sinus Floor Using Cone Beam Computed Tomography
Background and Objectives The topography of the sinus floor and its relationship with maxillary teeth roots varies with age, pneumatization size and grade, positioning of the teeth, and Genetics. This study used cone beam computed tomography (CBCT) to evaluate the distance between posterior teeth and the maxillary sinus floor in patients in Rafsanjan City, Iran. Materials and Methods This de...
متن کاملVolumetric accuracy of cone-beam computed tomography
PURPOSE This study was performed to investigate the influence of object shape and distance from the center of the image on the volumetric accuracy of cone-beam computed tomography (CBCT) scans, according to different parameters of tube voltage and current. MATERIALS AND METHODS Four geometric objects (cylinder, cube, pyramid, and hexagon) with predefined dimensions were fabricated. The object...
