Abstract

We present in vivo evaluation of a novel method for flow imaging and quantification that is based on conventional intravascular ultrasound (IVUS) imaging catheters. The quantification of flow is obtained from analysis of the rate of decorrelation of the radiofrequency ultrasound echo signal. Flow information is superimposed on the IVUS image using a colour scale. Integration of the blood velocity components normal to the scan plane allows calculation of the volume flow. IVUS and electromagnetic (EM) flowmeter recordings were obtained in vivo from instrumented pigs. IVUS now compares favourably to EM flow, which was used as a reference. Colour flow images are also demonstrated in a patient during catheterization for angioplasty.
