Objective To illustrate the basic operational principle of the control software item Part and value (IPV) of Elekta digital medical linac and specifically explain that the control software monitors and controls the subsystems in a real-time manner by using three types of items and Parts. Methods Firstly, the composition of the control system of Elekta digital medical linac was introduced. Then, the definition and category of the items and Parts of the control software and the basic principle of different types of items were illustrated. Finally, the application of control software items and Parts in real-time monitoring and controlling the operation of subsystems was evaluated by analyzing the motion control of high-power (HP) phase shifter. Results By analyzing the principle and citing a classical example to specifically illustrate the operational principle and application of control software IPVs, the users, especially the maintenance personnel, could master relevant theoretical knowledge, rapidly and accurately find the operational parameters during daily use and maintenance, besides analyze and resolve the problems based on the control principle of relevant subsystem. Conclusion Users, especially the maintenance personnel who master the working principle of these subprojects and their project sub-items can quickly and accurately check, calibrate the operating parameters via the control software, resolve equipment failure and avoid accidents caused by inappropriate operation in the daily use or maintenance.
