Image guided IMRT dosimetry using anatomy specific MOSFET configurations
We have investigated the feasibility of using a set of multiple MOSFETs in conjunction with the mobile MOSFET wireless dosimetry system, to perform a comprehensive and efficient quality assurance (QA) of IMRT plans. Anatomy specific MOSFET configurations incorporating 5 MOSFETs have been developed for a specially designed IMRT dosimetry phantom. Kilovoltage cone beam computed tomography (kV CBC...
متن کاملImage processing for IMRT QA dosimetry
We have automated the determination of the placement location of the dosimetry ion chamber within intensity-modulated radiotherapy (IMRT) fields, as part of streamlining the entire IMRT quality assurance process. This paper describes the mathematical image-processing techniques to arrive at the appropriate measurement locations within the planar dose maps of the IMRT fields. A specific spot wit...
متن کاملIn vivo prostate IMRT dosimetry with MOSFET detectors using brass buildup caps
The feasibility of using dual bias metal oxide semiconductor field effect transistors (MOSFET) detectors with the new hemispherical brass build up cap for in vivo dose measurements in Prostate IMRT treatments was investigated and achieved. A general formalism with various correction factors taken into account to predict Dmax entrance skin dose for the IMRT fields with MOSFETS was developed and ...
متن کاملPatient Specific IMRT Pre-Treatment Verification Using A Commercial Portal Dosimetry Software
Introduction: Electronic portal imaging devices (EPIDs) are extensively used for dosimetric information of pre-treatment field verification and in-vivo dosimetry for Intensity Modulated Radiotherapy (IMRT). In the present work, we have implemented the newly developed portal dosimetry software using independent dose prediction algorithm EPIDose and evaluated this new tool for the pretreatment IM...
متن کاملSmall field electron beam dosimetry using MOSFET detector
The dosimetry of very small electron fields can be challenging due to relative shifts in percent depth-dose curves, including the location of dmax, and lack of lateral electronic equilibrium in an ion chamber when placed in the beam. Conventionally a small parallel plate chamber or film is utilized to perform small field electron beam dosimetry. Since modern radiotherapy departments are becomin...
