X-ray image chain synchronization control scheme design and performance evaluation

This paper describes the working principle of the image chain's imaging system and analyzes the two imaging modes of the X-ray source as well as the two synchronization modes of the flat panel detector, with the goal of completing the design of the image chain's system imaging. Two schemes of synchronous control of the image chain, hardware control and software control, are achieved on the basis of the design of the image chain's imaging system. According to the experimental results, the hardware synchronization control, in comparison with the software synchronization control, enormously reduces the X-ray radiation time and the radiation received by the object as well as generating a lower CPU occupancy rate, which improves the safety of the performance of the image chain imaging system. Therefore, it can be concluded that hardware synchronization control is safer and more practical than software synchronization control. Lightweight cone-beam CT can be developed for use in mobile field hospitals and intensive care units to reduce the difficulty of doctors' operations.
