Abstract:
Objective To develop a new type of automatic moving table controlled by a single-chip microcomputer(SCM)for total body irradiation(TBI)to enable patients to receive prescribed doses of radiotherapy safely and accurately in a comfortable recumbent position.Methods The TBI table was composed of a frame,a moving mechanism and an intelligent control component.The table frame was made up of an aluminum alloy frame,polycarbonate panel,a field compensator and a lead block.The moving mechanism consisted of the driving wheel set and rudder wheel.The intelligent control component included an AT89S51 SCM,a LCD screen,a keyboard,two laser beam detection circuits,two ultrasonic ranging circuits and a pulse width modulation(PWM)power module.Results The TBI table enabled patients to receive precise radiotherapy with prescribed doses in a prone position throughout the treatment,and improved lung protection significantly.Conclusion The TBI table enhances patient comfort during radiotherapy and tolerance of prolonged treatment,while increasing the accuracy and safety of the treatment.
