Input of treatment planning data via a video frame grabber.
Video frame grabbers are powerful devices which perform rapid conversion of video images into digital format for subsequent computer processing. Recently, the cost of these devices has become competitive with sonic and magnetic digitizing tablets commonly used in radiation therapy treatment planning. Frame grabbers, plus all associated hardware/software can be interfaced to a variety of personal or microcomputers, and allow input of irregular treatment field and patient contour data into standard treatment planning systems. Such a system is described, which offers advantages of speed, accuracy, and resolution as compared to more conventional digitizing systems.
