Radiotherapy dose calculations in the presence of hip prostheses.
The high density and atomic number of hip prostheses for patients undergoing pelvic radiotherapy challenge our ability to accurately calculate dose. A new clinical dose calculation algorithm, Monte Carlo, will allow accurate calculation of the radiation transport both within and beyond hip prostheses. The aim of this research was to investigate, for both phantom and patient geometries, the capa...
متن کاملPatient‐specific calibration of cone‐beam computed tomography data sets for radiotherapy dose calculations and treatment plan assessment
PURPOSE In this work, we propose a new method of calibrating cone beam computed tomography (CBCT) data sets for radiotherapy dose calculation and plan assessment. The motivation for this patient-specific calibration (PSC) method is to develop an efficient, robust, and accurate CBCT calibration process that is less susceptible to deformable image registration (DIR) errors. METHODS Instead of m...
متن کاملEffective dose range for dental cone beam computed tomography scanners.
OBJECTIVE To estimate the absorbed organ dose and effective dose for a wide range of cone beam computed tomography scanners, using different exposure protocols and geometries. MATERIALS AND METHODS Two Alderson Radiation Therapy anthropomorphic phantoms were loaded with LiF detectors (TLD-100 and TLD-100 H) which were evenly distributed throughout the head and neck, covering all radiosensitiv...
متن کاملAssessment of Accessory Mental Foramen by Cone-Beam Computed Tomography
Introduction: Any foramen in the buccal surface of mandibular body that transfers mental nerve and vessels except mental foramen, is called Accessory Mental Foramen (AMF). The objective of this study was the determination of the AMF using cone-beam computed tomography (CBCT). Materials and Methods: this descriptive study was done on 180 CBCT projections which were selected by convenience samp...
متن کاملPrevalence of Idiopathic Osteosclerosis on Cone Beam Computed Tomography Images
Objectives: This study was performed to investigate the prevalence of idiopathic osteosclerosis on cone beam computed tomography (CBCT) images of patients. Methods: In this descriptive, cross-sectional study, 240 CBCT scans of patients (125 women, 115 men) referred to a private oral and maxillofacial radiology clinic in Tehran in 2013 were selected and evaluated. Presence of idiopathic osteosc...
