Abstract:
An X-ray image diagnostic apparatus comprising:an X-ray source for irradiating X-ray to an object to be examined; a flat panel X-ray detector for detecting X-ray that has transmitted through said object and for generating X-ray image data, said flat panel X-ray detector being arranged opposite to said X-ray source; image memorizing means for memorizing an X-ray image as image data; display means for displaying the image data as an image; operation means for outputting a start signal to read out the image; and readout control means for controlling readout of the X-ray image data from the flat panel X-ray detector when receiving the start signal to read out the image outputted, wherein said operation means comprises means for determining its readout range by means of the histogram of remaining data after reading out X-ray image data obtained in the previous time phase of the predetermined time phase from said flat panel X-ray detector to said image memorizing means, and said readout control means comprises means for controlling readout of the remaining data in said flat panel X-ray detector based on the readout range determined.
