MEGAVOLTAGE RADIATION THERAPY MACHINE COMBINED WITH DIAGNOSTIC IMAGING DEVICES

摘要

The patient setup and treatment verification for radiation therapy are donewith 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 byopenings (5) in the shared secondary wall of the accelerator room (3) orthrough an anteroom (109) to the mega voltage therapy room. Daily patientsetup for routine and three-dimensional conformal radiation therapy and onlinetreatment port verification with superimposed isodose are done with thepatient on the diagnostic imaging table (8). The patients are transferred fromthe diagnostic table (8) to the treatment table (2) without changing theverified treatment position. The patient setup in diagnostic rooms (6) iscaught up with the rapid turnover of patients in treatment room (3). Thediagnostic devices are also used for routine diagnostic imaging.
