Patent ID: 7218702

Claim:
An x-ray system which comprises: an x-ray source; an x-ray detector; a drive mechanism for moving the x-ray source and x-ray detector in a programmed path about a subject positioned therebetween; a computer configured to operate in accordance with a first stored program for moving the x-ray source and x-ray detector along a first scan path to acquire a first data set and for reconstructing an angiogram that depicts vasculature in the subject from the first data set and in accordance with a second stored program for moving the x-ray source and x-ray detector along a second scan path to acquire a series of tomosynthesis data sets and for reconstructing a corresponding series of images depicting inflow of contrast agent into the vasculature and tissues served by the vasculature from the series of tomosynthesis data sets and wherein the computer is configured to operate in accordance with a third stored program for producing a parametric image from information in the series of images indicative of blood perfusion in tissues served by the vasculature; and a display coupled to the computer for receiving and displaying the angiogram and the parametric image.
