Abstract:
Total body pan & scan radiotherapeutic instrument is a special bed whose heave and the vertical slide of its bedboard are controlled by the computer. The maximum vertical travel is about 2.3 meters. To distribute equal middle plane dose in the patient's body during scanning, the doctor divides the body into four segments and gives them different lengths and velocities as required. The instrument can travel as set automatically. The reliable interlock system is involved for the maximum safety. A serial of tests prove that the instrument runs stably and the dose distribution is very uniform.
