Ultrasound Based Volumetric Particle Tracking Method

Brief Description

Full Description

Disclosed is a technique that processes volumetric (3D) images in time to capture the motion of a body of fluid based on tracking/tracing changes in the fluid's brightness field. These changes can be due to inherent patterns in the scattered echo images or from injected particles shining in the flow. This technique processes the brightness information in the flow to obtain the velocity vector field in three dimensions over time.

Data consist of a multidimensional array that stores a quantity, such as the brightness of the fluid tracking agent. These dimensions represent the value of the quantity in three dimensional space and time. The spatial location of the quantity is known at the time of the acquisition, once the data is acquired by a volumetric image modality, such as, but not limited to a 4D ultrasound transducer, there is no need for estimation or computation of the depth or the third component of the coordinate system.
