Abstract
Estimation of blood flow parameters using non-invasive imaging techniques is described. In one implementation, temporally distinct image volumes are generated. Each respective image volume depicts a respective spatial distribution of a contrast agent within an imaged volume at a different time. The contrast agent movement at each different time from the plurality of image volumes is used in the estimation of a parameter related to the flow of blood within the imaged volume.
Claims20
A method for estimating blood flow, comprising:
- obtaining a plurality of temporally distinct image, wherein each respective image depicts a respective spatial distribution of a contrast agent within an imaged vessel at a different time;
- and
- estimating a parameter related to the flow of blood within the imaged vessel based on the temporal distribution and spatial distribution of the contrast agent.
An imaging system, comprising:
- an X-ray source and detector configured to cooperatively image a field of view over a time interval;
- one or more processing components configured to receive the projection data and to execute one or more routines, wherein the routines, when executed, cause acts to be performed comprising:
- reconstructing one or more signals generated by the detector to generate a plurality of temporally distinct images, each respective image depicting, at a different time, a spatial distribution of a contrast agent within a vessel within the field of view;
- and
- estimating a parameter related to the flow of blood within the vessel based on the temporal distribution and spatial distribution of the contrast agent.
One or more non-transitory computer-readable media encoding one or more routines, wherein the one or more encoded routines, when executed on a processor, cause act to be performed comprising:
- generating a plurality of temporally distinct images, each respective image depicting a respective spatial distribution of a contrast agent within an imaged vessel at a different time;
- and
- estimating a parameter related to the flow of blood within the imaged vessel based on the temporal distribution and spatial distribution of the contrast agent.
