Abstract
Official abstract text for this publication.
According to one embodiment, an image generation unit generates a first image during a large aperture period and a second image during a small aperture period. An image combining unit generates a composite image based on the latest second image and the specific first image. A display unit displays the composite image in real time. A determination unit determines whether to update the first image based on an index associated with the anatomical positional shift between the first image and the second image. A driving control unit enlarges a aperture to the large aperture, when the determination unit determines to update, and maintains the aperture at the small aperture, when the determination unit determines not to update.
First claim
Opening claim text (preview).
What is claimed is: 1. An X ray diagnostic apparatus comprising: an X ray tube configured to generate X rays; an X ray detector configured to detect X rays generated from the X ray tube and transmitted through a subject; an aperture variable collimator mechanism configured to limit a radiation field of X rays from the X ray tube; an image generation unit configured to repeatedly generate a first X ray image based on an output from the X ray detector during a period in which…
