Abstract

Official abstract text for this publication.

A diagnostic x-ray system includes a CT-image projection unit obtains a third perfusive-flow image by projecting a second perfusive-flow image obtained by computed tomography in the same direction as a projection direction in which an X-ray is projected toward a test subject to obtain a first perfusive-flow image. A positioning unit obtains positioning information by performing positioning of the first perfusive-flow image and the third perfusive-flow image. A perfusive-flow index calculation unit calculates a first perfusive-flow index from the first perfusive-flow image, and calculates a second perfusive-flow index from the third perfusive-flow image. A comparative-index calculation unit calculates a comparative index based on the first perfusive-flow index and the second perfusive-flow index, by comparing the first perfusive-flow index with the second perfusive-flow index, based on the positioning information obtained by the positioning unit.

First claim

Opening claim text (preview).

What is claimed is: 1. A diagnostic X-ray system, the system comprising: an image processing device including a CT-image projection unit that obtains a third perfusive-flow image of a coronary artery by projecting a second perfusive-flow image of the coronary artery obtained by a computed tomography (CT) apparatus in a projection direction, the projection direction being a same direction as a direction in which an X-ray is projected toward a test subject to obtain a first perfusiv…
