Abstract
Recent developments of intravascular ultrasound (IVUS) offer some new features for the detection and quantification of vascular disease which are very valuable for clinical diagnosis. Making possible visualization of the full circumference of the vessel, IVUS allows the inspection of lumen and plaque shape by one single tomogram. Such views are successfully used for planimetry to overcome special problems such as bifurcations or overlapping vessels. In addition, IVUS is used to obtain plaque thickness and echogenicity for determination of its area and composition. It is established that intravascular ultrasonic imaging provides best results in quantifying atherosclerotic changes in vessels1,2. Decisions for optimal treatment are usually made in terms of grey scaled video images, which are processed from the amplitude of ultrasonic echo signals. However, there is much more information in radio-frequency (RF) echo signal which should be used for tissue characterization and identification3as well as special experiences in soft tissue classification4,5.
