Systems, methods, and devices for radiation beam asymmetry measurements using electronic portal imaging devices

Systems and methods for determining beam asymmetry in a radiation treatment system using electronic portal imaging devices (EPIDs) without implementation of elaborate and complex EPID calibration procedures. The beam asymmetry is determined based on radiation scattered from different points in the r...
