Sample URI RF data files:

You will need to decompress these zip files before loading them with URI-OPT. Each zip file also contains a JPEG file showing the processed image for you to compare your own results with. For color flow and spectral Doppler modes, an attached text file lists the parameters used in the sample process, which are the default setting and parameters automatically loaded from the file header.

URI 2D B-mode sample RF data
(zipped, 4.79MB, 9/25/2003)
Multi-layered phantom image acquired with phased array, using multiple transmit focal zones. (Blending is used.)

URI 2D color flow sample RF data
(zipped, 5.00MB, 9/25/2003)
Flow inside 4.2mm-ID silicone tubing embedded in gelatin-graphite phantom.
