Upgraded 2-D Therapy Beam Measurement System Available

MapCHECK version 3.1 is now available. Version 3.1 adds the ability to print reports directly to a PDF file for data archiving; enhanced beam QA; rotation of planned files; BestFit Analysis; ruler tool; and much more.
The MapCHECK is a 2-D therapy beam measurement system intended for quick and precise verification of the dose distribution resulting from an IMRT plan. Beam measurement is accomplished using a grid of 445 diode detectors that are housed between two sheets of solid acrylic. The MapCHECK measures the integrated ABSOLUTE dose at all detector locations, each of which has been corrected to the central detector sensitivity. This measured dose map is then automatically normalized and compared to a normalized imported treatment plan dose map, all in less than one minute.
