Development and validation of echo PIV

The combination of ultrasound echo images with digital particle image velocimetry (DPIV) methods has resulted in a two-dimensional, two-component velocity field measurement technique appropriate for opaque flow conditions including blood flow in clinical applications. Advanced PIV processing algorithms including an iterative scheme and window offsetting were used to increase the spatial resolution of the velocity measurement to a maximum of 1.8 mm×3.1 mm. Velocity validation tests in fully developed laminar pipe flow showed good agreement with both optical PIV measurements and the expected parabolic profile. A dynamic range of 1 to 60 cm/s has been obtained to date.

This project was made possible in part by grants from the American Heart Association (Desert-Mountain Affiliate), National Science Foundation (EECS-0225405) and NIH (HL 67393, HL 072738). One of the authors (HB Kim) was supported by the post-doctoral fellowship program of the Korean Science and Engineering Foundation (KOSEF). We would also like to thank Craig Lanning and Scott Kirby for their technical assistance with the experimental apparatus and ultrasound system.
