Method and apparatus for photon therapy

A photon therapy unit implement has a flexible head for conforming to a body part to be treated. The head has a thermally conductive backing to remove heat from the treatment area. The operation of the head is monitored by a photon detector to provide a feedback to the diode drive circuit to maintain the output at the required level. Operation of the head is monitored by a microprocessor which performs a diagnostic function and reports on defects. The treatment protocol is generated by a main control unit that formulates a treatment waveform from a set of treatment protocols. The selection of protocols is performed through a graphical user interface (GUI) which allows selection of treatment areas and customization of treatment as well as maintaining patient history and annotations.
