Dosimetric and radiobiological comparison for quality assurance of IMRT and VMAT plans
INTRODUCTION The gamma analysis used for quality assurance of a complex radiotherapy plan examines the dosimetric equivalence between planned and measured dose distributions within some tolerance. This study explores whether the dosimetric difference is correlated with any radiobiological difference between delivered and planned dose. METHODS VMAT or IMRT plans optimized for 14 cancer patient...
متن کاملDosimetric Study of an Indigenous and Heterogeneous Pelvic Phantom for Radiotherapy Quality Assurance
Introduction: In vitro dosimetric verification prior to patient treatment plays a key role in accurate and precision radiotherapy treatment delivery. Since the human body is a heterogeneous medium, the aim of this study was to design a heterogeneous pelvic phantom for radiotherapy quality assurance. Material and Methods: A pelvic phantom was ...
متن کاملA comparison of the quality assurance of four dosimetric tools for intensity modulated radiation therapy
BACKGROUND This study was designed to compare the quality assurance (QA) results of four dosimetric tools used for intensity modulated radiation therapy (IMRT) and to suggest universal criteria for the passing rate in QA, irrespective of the dosimetric tool used. MATERIALS AND METHODS Thirty fields of IMRT plans from five patients were selected, followed by irradiation onto radiochromic film,...
متن کاملRadiobiological model-based bio-anatomical quality assurance in intensity-modulated radiation therapy for prostate cancer
A bio-anatomical quality assurance (QA) method employing tumor control probability (TCP) and normal tissue complication probability (NTCP) is described that can integrate radiobiological effects into intensity-modulated radiation therapy (IMRT). We evaluated the variations in the radiobiological effects caused by random errors (r-errors) and systematic errors (s-errors) by evaluating TCP and NT...
متن کاملDosimetric and radiobiological evaluation of Accelerated Partial Breast Irradiation Techniques
Accelerated Partial Breast Irradiation (APBI) decreases the duration of entire radiotherapy course (Sanders ME et al 2007). The reduced treatment volume makes APBI more appealing to both clinicians and patients. The uses of brachytherapy either as HDR or LDR interstitial implants have shown promising results which are obvious from the published research works (Arthur DW et al 2003; Baglan KL et...
