<P>PROBLEM TO BE SOLVED: To provide an X-ray diagnostic apparatus capable of processing an image series in real time and enhancing a signal to noise ratio. <P>SOLUTION: The X-ray diagnostic apparatus is provided with X-ray devices (1, 2) for generating an X-ray (3), an X-ray detector (5) for detecting an X-ray image and converting it into an electric signal sequence, an image system (6) for processing the electric signal sequence, and a reproducing apparatus (7). The imaging system (6) includes edge detectors (11 to 13) for detecting edges existing in each X-ray image, and a filter processing apparatus (14) for applying filter processing to each X-ray image along the edges. The X-ray diagnostic apparatus can carry out the individual image processing in real time. The X-ray diagnostic apparatus can perform filter processing along the edges on the basis of signal adaptation through the detection of the weight of the edges. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
