Fluid Flow Rate Determinations Using Velocity Vector Maps
12 Aug 21
A method of determining volume flow rate of a bodily fluid in a biological conduit includes determining a cross-sectional area of a biological conduit using a velocity vector map representing moving entities or moving fluid portions in a bodily fluid flowing within the biological conduit, calculating an average speed of the moving entities or moving fluid portions in the bodily fluid flowing across the determined cross-sectional area of the biological conduit, and calculating volume flow rate of the bodily fluid in the biological conduit from the determined cross-sectional area and the calculated instantaneous or average speed.

Fluorescence Based Flow Imaging and Measurements
6 Jan 21
Fluorescence based tracking of a light-emitting marker in a bodily fluid stream is conducted by: providing a light-emitting marker into a fluid stream; establishing field of view monitoring by placement of a sensor, such as a high speed camera, at a region of interest; recording image data of light emitted by the marker at the region of interest; determining time characteristics of the light output of the marker traversing the field of view; and calculating flow characteristics based on the time characteristics.
