MEGAVOLTAGE RADIATION THERAPY MACHINE COMBINED WITH DIAGNOSTIC IMAGING DEVICES

摘要

The patient setup and treatment verification for radiation therapy are done with diagnostic imaging devices (7) which are connected to a room (3) containing a mega voltage radiation therapy machine (1). The diagnostic rooms (6), and the mega voltage therapy room (3) are connected to each other by openings (5) in the shared secondary wall of the accelerator room (3) or through an anteroom (109) to the mega voltage therapy room. Daily patient setup for routine and three-dimensional conformal radiation therapy and online treatment port verification with superimposed isodose are done with the patient on the diagnostic imaging table (8). The patients are transferred from the diagnostic table (8) to the treatment table (2) without changing the verified treatment position. The patient setup in diagnostic rooms (6) is caught up with the rapid turnover of patients in treatment room (3). The diagnostic devices are also used for routine diagnostic imaging.
