Abstract
A radiation dosimetry system ( ) 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 ( ) used for alignment purposes. The system ( ) is controlled and monitored by a CPU ( ) which receives instructions from a radiologist operating a control panel ( ), and displays control parameters, data and graphics to the radiologist on a display ( ). The CPU ( ) controls an RF system operating through a broad-band antenna ( ) and directed at the target area ( ). The CPU ( ) controls operation of a radiation source ( ), which may be a conventional linear accelerator, for directing radiation at the target area ( ). The radiation source ( ) includes a collimator ( ) or similar apparatus for shaping a radiation beam for accurate application to the target area ( ). A pair of RF receivers ( ) and ( ) are positioned such that they are spaced apart and opposite from the CPU antenna ( ) with respective antennas ( ) and ( ) directed at the target area ( ). Communication connections ( ), ( ), ( ), ( ) and ( ) interconnect the various elements of the system ( ).
