Coronary Artery Flow Imaging with an Intraluminal Array

Here are two images from a 64 element, 20MHz IVUS system. Both images present color coded blood speed information superimposed over the gray scale B-Scan image. These images are from an in-vivo investigation of a pig femoral artery conducted in our lab. Images were contructed from radio frequency ultrasound data acquired from a real-time scanner operating at approximately a 10.5 Hz frame rate.
