Title:
IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2012130648
Kind Code:
A
Abstract:

To generate an X-ray transmission image for analyzing the movement functions of the heart while reducing the burden on a subject.

An X-ray diagnostic apparatus includes a difference image generating unit 26b and a system controlling unit 21. The difference image generating unit 26b generates a difference image by calculating a difference in a second X-ray transmission image from a first X-ray transmission image, the second X-ray transmission image being an image in which a myocardial tissue of the examined subject is not opacified and the first X-ray transmission image being an image in which the myocardial tissue of the examined subject is opacified with a contrast agent that has been injected into a coronary artery. The system controlling unit 21 exercises control so that a display unit 23 displays the difference image generated by the difference image generating unit 26b.
