Abstract
A microcomputer-based system was implemented in an on-line portal imaging system to determine portal misalignment in radiation therapy. Reference markers derived from a patient simulation film are superposed on the daily on-line portal images for visual evaluation of placement accuracy. The ability to check the alignment after administration of 3-6 cGy of radiation and the minimal operator interaction required make this system useful in radiation therapy delivery.
