Abstract:
CT laser simulation positioning system is a necessary auxiliary device for radiotherapy. Its main purpose is to position patients by simulating different kinds of treatment machine. In order to demarcate the mark of the iso-center, it is common to use the laser positioning device to indicate the iso-center. The kernel technology of the laser positioning system is the controlling of the step progress motor by using the MCS, which is to control the movement of step progress motor using the wheel of the motor. This design uses MCS-51 to control step progress motor by the way of exporting the rectangle wave form through I/O port of 8255 chip. The system configuration is simple, the operation is convenient and the positioning is precise.
