X-ray diagnostic apparatus, image processing apparatus, and method of calculating filter coefficients used for image formation processing in x-ray diagnostic apparatus and the like
A tomosynthesis image is generated by applying preprocessing to each image obtained by capturing a plurality of X-ray images at a plurality of X-ray tube positions and then performing filtering processing and backprojection. At this time, a proper filter coefficient used filtering is determined for each scan track, each image frame, and each pixel position in an image.
