Abstract
Approaches for assessing hemodynamic characteristics for an organ of interest are related. In one implementation, a fluid dynamics model may be provided with data derived from an anatomic imaging modality and blood flow information derived by ultrasound to derive the desired hemodynamic characteristics. In one such implementation, a fractional flow reserve is estimated.
Claims26
A method for assessing hemodynamic information, comprising:
- generating or acquiring anatomic information comprising at least a location and topology of a narrowing of a blood vessel;
- generating or acquiring blood flow information comprising at least flow information in one or more vessels proximal to the location of the narrowing;
- and
- estimating hemodynamic information based at least on the anatomic information and the blood flow information.
One or more non-transitory computer-readable media encoding one or more processor-executable routines, wherein the one or more routines, when executed by a processor, cause acts to be performed comprising:
- accessing anatomic information comprising at least a location and topology of a narrowing of a blood vessel;
- accessing or acquiring blood flow information comprising at least flow information corresponding to one or more vessels proximal to the narrowing;
- and
- estimating hemodynamic information based at least on the anatomic information and the blood flow information.
A processor-based system, comprising:
- a storage encoding one or more processor-executable routines, wherein the routines, when executed cause acts to be performed comprising:
- generating or acquiring anatomic information comprising at least a location and topology of a narrowing of a blood vessel;
- generating or acquiring blood flow information comprising at least flow information corresponding to one or more vessels proximal to the narrowing;
- and
- estimating hemodynamic information based at least on the anatomic information and the blood flow information;
- a memory configured to encode the one or more processor-executable routines prior to execution;
- and
- a processing component configured to access and execute the one or more routines when encoded by the memory.
