摘要： Pixel data in a region of a flat panel detector is obtained and displayed. For example, pixel data in a region irradiated with X-ray is obtained and displayed. The region to be irradiated with-the X-ray is estimated according to a degree of opening of an X-ray beam limiting device and a distance between the X-ray beam limiting device and the flat panel detector. Further, it can be determined from pixel data value of the flat panel detector also. A region of a patient can be also determined from the pixel data. Thus, an image corresponding to the entire flat panel detector, an image corresponding to an X-ray irradiation region and an image corresponding to a patient region can be displayed. A resolution for obtaining the pixel data is changed corresponding to the size of a region in the flat panel detector whose pixel data should be obtained and a processing resolution of an image processing means at post step. Particularly in an X-ray diagnostic apparatus of bi-plane structure, an observation region can be traced flexibly.

摘要： When a plurality of X-ray images in a time sequence is stored in an image data storing unit (25), a marker coordinate detecting unit (26a) detects coordinates of a stent marker in each X-ray image, and a motion vector calculating unit (26b) calculates, with coordinates of the stent marker detected in a first frame as reference coordinates, a motion vector of the coordinates of the stent marker detected in each X-ray image of a second and subsequent frames with respect to the reference coordinates. Then, a filter application range determining unit (26c) moves and determines an application range of a smoothing filter in each X-ray image based on the motion vector, and the filtered image generating unit (26d) generates a filtered image by performing a process by the smoothing filter between application ranges determined in a process target image and a reference image.
