Abstract

In various embodiments, systems and methods can provide accurate measurements of blood flow dynamics in a subject. Projection data acquired during a computed tomography (CT) scan of the subject can be used to determine information representing inflow of a contrast material. Accordingly, a measurement of flow velocity, in addition to other aspects of flow, may be obtained from the projection data.
