Abstract
An imaging scanner includes a radiation source, a radiation detector, and a computer programmed to decompose CT data acquired by the radiation detector into a set of pixels, each pixel having at least a first basis material content and a second basis material content. The computer is further programmed to identify a first subset of the set of pixels as a possible embolism, based on the content of the first basis material and the content of the second basis material.
