PROBLEM TO BE SOLVED: To provide an X-ray image diagnostic apparatus and an X-ray diaphragm position correction method capable of correcting the position of an X-ray diaphragm on an X-ray image accurately.SOLUTION: An X-ray diagnostic apparatus 1 calculates a position of an X-ray diaphragm on an X-ray image from a position of a diaphragm vane measured by a device condition measurement device 14, displays the calculated position of the X-ray diaphragm on the X-ray image, and receives position adjustment therefor. When the position of the X-ray diaphragm is adjusted, an adjustment amount is stored in a correction data storage section 43 as correction data. In subsequent imaging, the position of the X-ray diaphragm calculated from the position of the diaphragm vane measured by the device condition measurement device 14 is corrected by reference to the correction data stored in the correction data storage section 43.SELECTED DRAWING: Figure 2 |
