Abstract: According to one embodiment, the X-ray image diagnosis apparatus comprises an X-ray generator, an X-ray restriction unit, a first X-ray detector, a second X-ray detector, and a drive. The X-ray generator generates X-rays to be applied to a subject. The X-ray restriction unit is disposed between the subject and the X-ray generator to restrict X-rays outside an opening region which is formed using a metal plate. The first X-ray detector has a first detection region in which X-rays that pass through the subject are detected. The second X-ray detector has a second detection region which is smaller than the first detection region and which has a high spatial resolution. The drive moves the first and second X-ray detectors so that the second detection region includes an irradiation region of the subject formed by the opening region.

Abstract: According to one embodiment, an image processing apparatus includes processing circuitry. The processing circuitry obtains a parameter value representing temporal information on blood flow for each pixel of multiple image data items, and generates a parameter image by determining a pixel value of each pixel according to the parameter value representing the temporal information on blood flow. The processing circuitry further generates a composite image of an X-ray fluoroscopic image of an object obtained in real time and a road map image using at least a part of the parameter image, and causes a display to display the composite image.

Abstract: According to one embodiment, an image processing device includes processing circuitry. The processing circuitry sequentially acquires image data of time-sequential DSA images of an object, and acquires a parameter value for each pixel based on temporal change of a pixel value of the each pixel corresponding to the same region of the object in the sequentially acquired image data of time-sequential DSA images. Further, the processing circuitry sequentially generates image data of parameter images in such a manner that identification information according to the parameter value is assigned to the each pixel corresponding to the same region of the object, each time image data of a DSA image of the latest time phase being acquired.

Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an input circuit, an X-ray tube and an X-ray detector, and processing circuitry. The input circuit converts an input operation into an electric signal and output the electric signal. The X-ray tube and the X-ray detector image X-ray images of an object. The processing circuitry detects positions of feature points of devices from the X-ray images; generates corrected images by motion correction of the X-ray images when an electric signal corresponding to an input operation for selecting a predetermined device has been input from the input circuit; and displays the corrected images as the moving image in real time. The motion correction is performed based on positions of a feature point of the selected device. At least a part of the selected device nearly stops when the X-ray images have been displayed, by the motion correction.
