X-RAY DIAGNOSTIC DEVICE AND X-RAY DIAGNOSTIC DEVICE CONTROL METHOD

摘要

An x-ray diagnostic device according to an embodiment comprises: a range setting unit (12) sets a photography range for photographing with a photography unit (2); an x-ray aperture unit which adjusts the x-ray illumination field of the photography unit (2); a gap setting unit (13) which sets a photography gap when photographing the photography range with the photography unit (2); a region setting unit (14) which sets an image stitching region size when stitching a plurality of x-ray images together; an illumination field acquisition unit (16) which, using the photography gap and the image stitching region size, derives a target x-ray illumination field of the photography device (2); and a control unit (3a) which controls the x-ray aperture unit on the basis of the target x-ray illumination field.
