Abstract
A radiation dosimetry system (110) using miniature implanted transponder balls. A patient having a tumor that is the target of the radiation treatment lies in a treatment area with the tumor positioned beneath a target (112) used for alignment purposes. The system (110) is controlled and monitored by a CPU (114) which receives instructions from a radiologist operating a control panel (116), and displays control parameters, data and graphics to the radiologist on a display (118). The CPU (114) controls an RF system operating through a broad-band antenna (120) and directed at the target area (112). The CPU (114) controls operation of a radiation source (122), which may be a conventional linear accelerator, for directing radiation at the target area (112). The radiation source (122) includes a collimator (124) or similar apparatus for shaping a radiation beam for accurate application to the target area (112). A pair of RF receivers (126) and (128) are positioned such that they are spaced apart and opposite from the CPU antenna (120) with respective antennas (130) and (132) directed at the target area (112). Communication connections (133a), (133b), (133c), (133d) and (133e) interconne…
