background: exposure conditions in ct examinations are quite different from conventional xray. in ct examination higher dose is given to patient in comparison with the dose in other diagnostic examinations. in order to calculate organ effective dose in chest ct, monte carlo simulation has been used in this study. materials and methods: the impact survey data were used to determine the parameter...

Despite the availability of national and international guidelines, an accurate efficient, patient-specific, deformable image registration (DIR) validation methodology is not yet established, several groups have found incompatibility various digital phantoms with commercial systems. To evaluate quality computed tomography (CT) on-board cone-beam CT (CBCT) DIRs, a novel was developed tested on 10...

Introduction: Electronic portal imaging devices (EPIDs) could be used to dose verification of radiotherapy treatment plans. In vivo dose verification is performed to reduce differences found between dose delivered to the patient and the prescribed dose. The aim of this study was to perform a fast and efficient technique for the verification of delivered dose to the patient usin...
