Method and system for facilitating physiological computations

摘要

A system for noninvasively determining at least one physiological characteristic of a patient may include at least one computer system configured to, using a three-dimensional surface mesh model created using patient-specific imaging data, create a three-dimensional combined surface and volume mesh model, including at least a first model portion that has a different spatial resolution than at least a second model portion. The computer system may be further configured to input the three-dimensional surface and volume mesh model into a fluid simulation system and determine a measurement of the physiological characteristic, using the fluid simulation system.

1. A system for non invasively determining at least one physiological characteristic of a patient, the system comprising:
at least one computer system configured to:
use a hardware processor of the at least one computer system to create a three-dimensional combined surface and volume mesh model of the patient using patient-specific imaging data of the patient by forming multiple elongated shaped elements of the combined surface and volume mesh model along a direction of fluid flow through the combined surface and volume mesh model, the combined surface and volume mesh model including at least a first model portion that has a different spatial resolution than at least a second model portion, the first model portion including shaped elements that are elongated relative to shaped elements of the second model portion;input the three-dimensional combined surface and volume mesh model of the patient into a fluid simulation system; anddetermine a measurement of the physiological characteristic of the patient, by running the fluid simulation system on the three-dimensional combined surface and volume mesh model of the patient.
