Abstract

Apparatus and methods are described for use with an imaging device () configured to acquire a set of angiographic images of a lumen. At least one processor () includes blood-velocity-determination functionality () that determines blood velocity within the lumen, via image processing. Current-flow-related-parameter-determination functionality () determines a value of a flow-related parameter at the location based upon the determined blood velocity. Flow-related-parameter-receiving functionality () receives an indication of a value of a second flow-related parameter of the subject, and index-determination functionality () determines a value of a luminal-flow-related index of the subject at the location, by determining a relationship between the value of the current flow-related parameter and the value of the second flow-related parameter. Other applications are also described.
