Fiber Optic Back Pointer A176A and A177A
 
     Description:The Gammex Fiber Optic Back Pointer defines the exit point of the radiation beam when used with Gammex therapy lasers. The Gammex Back Pointer projects a single line which intersects the side light, defining the exit point on the patient's body. This can save the patient and therapy center time, while ensuring the most accurate patient positioning possible. The A176A provides a standard line, and the A177A provides a longer line which is beneficial if the couch is moved up, losing the intersecting point. Designed to be used with the Gammex Ther-A-Cross “X” or Tri-Flex wall mounted laser systems, the Fiber Optic Back Pointer can be adapted for use on all therapy equipment. With this fiber optic system, the laser generator can be mounted at any convenient location, even remote sites, but often inside the gantry of the therapy machine. The laser light is piped through a flexible fiber optic cable to a compact projection head that is easily mounted on or in the radiation therapy unit. Clearance is not a problem because of the small size of the output head. The cable and optical heads carry no electrical power and will not interfere with other equipment. The optical head projection defines a plane containing the axis of rotation and the radiation source. The intersection of this plane and transverse plane (created by lateral and overhead lasers) is the radiation exit axis. The exit axis is quickly and easily defined with a Fiber Optic Back Pointer.
