Simplified bite-block immobilization of the head.
The use of bite blocks to immobilize a patient's head for therapeutic radiology usually involves the mechanical positioning of a rod protruding from the block. This position must be recorded at simulation time and preset for each treatment session. The authors describe a device which simply requires the vertical positioning of an auxiliary bar which, in turn, is attached vertically to the primary rod at simulation time.
