Intravascular Ultrasound Tissue Characterization

Tissue Characterization of Coronary Plaques Using Intravascular Ultrasound/Virtual Histology

Most studies related with plaque histopathology and/or morphology are based on the gray scale intravascular ultrasound (IVUS) and autopsy findings, although IVUS is limited for differentiating echolucent areas, and tissue shrinkage almost always occur during tissue fixation. In addition, autopsy studies can not establish the causal relationship between the autopsy findings and the clinical find...

Automated Tissue Characterization in Intravascular Ultrasound Gray-scale Images

Intravascular ultrasound (IVUS) is a widely used interventional imaging modality in displaying the morphology and even component of the vessel wall including possible plaques. Accurate identification of different types of atherosclerotic plaques are essential for diagnosis and treatment planning of coronary artery diseases. The shear stress distribution at the vessel branching exhibits consider...

Intravascular Ultrasound Images Vessel Characterization Using AdaBoost

This paper presents a method for accurate location of the vessel borders based on boosting of classifiers and feature selection. Intravascular Ultrasound Images (IVUS) are an excellent tool for direct visualization of vascular pathologies and evaluation of the lumen and plaque in coronary arteries. Nowadays, the most common methods to separate the tissue from the lumen are based on gray levels ...
