You’re Going To Love This
RIT's patented Plan Base Calibration routine gives you the ability to make quick relative or absolute comparisons between any dose map and your Film, EPID, CR and Ion Chamber Array images! Using any dose map images (no special patterns needed), another image can be calibrated. Overlaying this calibration with an existing absolute calbration can give you an idea of the overall accuracy. This technique can be used to eliminate field size dependencies in film, EPID and CR images. It can also be used with an ion chamber array to produce fast absolute dose calibration at a multitude of points.
This routine was developed in cooperation with Dr Arthur Olch, PhD, Chief of Physics, Children's Hospital, Los Angles, CA. "Validation of a Plan-based Calibration Method for Relative Dosimetry", A. Olch, AAPM 2006 Meeting, Poster paper #SU-FF-T-499.
