Laser lights are more familiar and widely used because of their collimation and energy concentration. In the CT simulation positioning system, the laser positioning system has a special and important role. It realizes the establishment of the positioning reference point and the treatment center under the precise control of the computer, which is an important part of quality assurance. The basic mechanical principle is to use the stepper motor control system to control the precise feed of the circulating ball screw to realize the precise movement of the laser light. The specific accuracy is determined by the accuracy of the stepper motor and the ball screw. The precision and feed rate error of THK precision ball screw and Sanyo Electric stepping motor products are less than 0.01mm.
