How to calculate Cross-beam calibration
Cross beam calibration is a method of calculating a calibration equation, which usually employs one large vial (e.g., a Cross beam calibration phantom of GeVero Co.) filled with a polymer gel dosimeter and irradiated with several beams of a high-energy photons. The beams cross each other to boost the dose on the crossing points.
The Cross beam calibration phantoms can be seen here: http://polygevero.pl/product/phantoms/Cross-beam-calibration-phantom.
The polyGeVero® software enables the fast computation of the Cross beam calibration data. This movie presents how to do this easily using the software and the GeVero® Cross beam phantoms.
