Introduction: The conventional methods of dosimetry are not capable of dosimetry in such a small volume of less than one cubic millimeter. Although the polymer gel dosimetry method based on magnetic resonance imaging (MRI) could achieve three dimensional dosimetry with high resolution, a spatial resolution evaluation based on gel dose modulation transfer function has not been investigated yet. ...

Abstract Introduction: In vivo dosimetry verification is currently a necessity in radiotherapy centres Europe countries as one of the tools for patient-specific QA, and now its demand rising developed countries, such Malaysia. The aim this study to characterize commercial EPID-based implementation treatment Materials Methods: work, sensitivity performance commercially available system, EPIgray®...

static verification and software testing are not able to verify software single-handedly. therefore, another approach called run-time verification dealing with verifying software behavior against constraints at run-time received attention. however, the run-time verification faces the problem of verification of run-time activities against the constraints are specified in high-level and abstractl...

BACKGROUND Intraoperative electron radiotherapy (IOERT) is a highly selective radiotherapy technique which aims to treat restricted anatomic volumes during oncological surgery and is now the subject of intense re-evaluation. In vivo dosimetry has been recommended for IOERT and has been identified as a risk-reduction intervention in the context of an IOERT risk analysis. Despite reports of fruit...

Patient-specific pretreatment verification of intensity-modulated radiation therapy (IMRT) or volumetric-modulated arc therapy (VMAT) is strongly recommended for all patients in order to detect any potential errors in treatment planning process and machine deliverability, and is thus performed routinely in many clinics. Portal dosimetry is an effective method for this purpose because of its pro...

BACKGROUND We performed a clinical audit of preoperative rectal cancer treatment at two European radiotherapy centres (Poland and Spain). The aim was to independently verify adherence to a selection of indicators of treatment quality and to identify any notable inter-institutional differences. METHODS A total of 162 patients, in Catalan Institute of Oncology (ICO) 68 and in Greater Poland Can...
