To develop an efficient and economic daily quality research tool (DQRT) for daily check of multiplatform linear accelerators (LINACs) with flattening filter (FF) and flattening filter-free (FFF) photon beams by using an Electronic Portal Image Device (EPID). After EPID calibration, the monitored parameters were analyzed from a 10cm×10cm open and 60° wedge portal images measured by the EPID with 100MU exposure. Next, the repeatability of the EPID position accuracy, long-term stability, and linearity between image gray value and exposure
