Epiqa
Complete EPID dosimetry
EpiqaTM is a program that allows to convert a dosimetric image acquired by an EPID into a dose map and to compare the dose map with a reference dose distribution. It is possible to utilize Epiqa for a verification of static as well as intensity modulated fields, including RapidArc® fields.
The portal dosimetry image conversion to dose map is based on the GLAaS algorithm as described in Nicolini G. et al: GLAaS – an absolute dose calibration algorithm for an amorphous silicon portal imager. Aplications to IMRT verification. Med Phys 2006; 33: 2839-2851
