Position control of operating fable for radiation therapy - arrangement and method for holding a position reference between an emitter and a receiver object
Реферат: The radiation source is accommodated in a fastening device and produces a radiation beam which impinges on the target area of the patient on a table which can move in the X and Y directions. There is a sensor for reflected radiation, which produces a signal proportional to the intensity for feeding it into the control arrangement. The controls actuate the object drive to move into the middle of the beam where the intensity is greatest, using blocks. The control system has facilities for comparing the intensity signal with the position location signal, and also for controlling the shape of the beam. Removable radiation absorbsion blocks are kept in position by spring loaded holders. Timers and slits are provided to control and check the beam.
