In order to improve the performance of X ray geometric imaging, the key factors of size and image of X ray focus and
geometric clarity as well as imaging quality of real time imaging system were studied by using software simulation.
Analyze the reasons and factors that affecting the X - ray focus size and blurred image, evaluated the performance of X
ray geometric imaging through the relationship between the relationship of X-ray focus size and image geometric
definition. It provides a low cost and high efficiency solution for the selection of X-ray tube in the system design.
