<p><P>PROBLEM TO BE SOLVED: To provide a diagnostic x-ray system and a method thereof capable of comparing perfusion before and after a medical cure without increasing an exposure dose. <P>SOLUTION: A diagnostic x-ray system includes: a CT-image projection unit that 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 that obtains positioning information by performing positioning of the first perfusive-flow image and the third perfusive-flow image; a perfusive-flow index calculation unit that 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; and a comparative-index calculation unit that 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. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
