Claim Text:
1. An X-ray image diagnostic apparatus comprising: an X-ray imager configured to generate projection data by performing X-ray imaging in first and second imaging modes for a patient; an image data generation processor configured to generate reference image data based on projection data in the first imaging mode and image data for positional deviation correction based on projection data in the second imaging mode, the second imaging mode utilizing low-rate or intermittent X-ray imaging compared to the first imaging mode; a position information acquisition processor configured to acquire position information of a treatment device inserted into a body of the patient; a position information correction processor configured to correct the position information of the treatment device on the basis of the position information of the treatment device and treatment device information of the image data for positional deviation correction, which is collected by X-ray imaging in the second imaging mode utilizing low-rate or intermittent X-ray imaging for the patient to whom the treatment device has been inserted; a display configured to display the reference image data to which the corrected position information is added; and an imaging timing setting processor configured to set an imaging timing in the second imaging mode on the basis of measurement results using measurement functions, wherein the imaging timing setting processor includes at least one of an elapsed time measurement function of measuring an elapsed time from a start instruction signal of the second imaging mode or a preceding imaging timing signal, a device movement speed measurement function of measuring a movement speed of the treatment device, and a correction data measurement function of measuring a size of correction data.
