X-ray diagnostic apparatus for analyzing scattered X-rays by using X-ray shield member

摘要

An X-ray diagnostic apparatus analyzes scattered X-ray distribution from total X-ray transmission data by employing an X-ray shield member. One of plural X-ray shield members is selected based on the X-ray magnifying factor of a region of interest (ROI) in a patient. The scattered X-ray distribution I.sub.sc (x,y) over the entire X-ray projection area is calculated by utilizing a method of linear interpolation and the actually measured scattered X-ray components.
