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
摘要：
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.
摘要（中）：

通过对通过在多个X射线管位置捕获多个X射线图像而获得的每个图像应用预处理，然后执行滤波处理和反投影，生成断层合成图像。 此时，针对每个扫描轨迹，每个图像帧以及图像中的每个像素位置确定使用滤波系数的滤波系数。
