Epiqa software suite unlocks your EPID as a comprehensive plan and machine QA device. Dose-to-water matrix provided by the program can be computed from acquired dosimetric integrated image for IMRT, RapidArc® fields, open and wedged beams.
Epiqa is based on 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

Patient plan QA comparing dose delivered during RapidArc to portal imager with dose calculated by Eclipse to water phantom. Clinac and MLC QA for RapidArc treatment using Varian’s recommended tests.
Patient plan QA of IMRT field in treatment gantry angle. Compare dose to water calculated by Eclipse using patient plan algorithm with the dose distribution provided by Epiqa and Portal Vision.
Super fast treatment beam QA using Portal Vision is supported by Epiqa. Verify beam symmetry, homogeneity and energy at Dmax in water without using water phantom. Determine output factors, wedge angles and compare Eclipse calculation of open and wedged beams with the measurement.
Supports quantitative analysis of 2D dose matrices calculated by Eclipse TPS. Compare Eclipse results for commissioning of new Eclipse algorithm or evaluation of new algorithms, e.g. PBC versus AAA.
