Intravascular and Intracardiac Ultrasound Imaging
C onsiderable attention is currently being focused on the development of intravascular and intracardiac ultrasound imaging.1-4 Variously termed as "ultrasound angioscopy," "intravascular ultrasound imaging," or "intraluminal ultrasound imaging," this technique basically refers to the imaging modality of visualizing blood vessels and cardiac structures by an ultrasound transducer placed at the t...
متن کاملIntegrated intravascular optical coherence tomography ultrasound imaging system.
We report on a dual-modality optical coherence tomography (OCT) ultrasound (US) system for intravascular imaging. To the best of our knowledge, we have developed the first integrated OCT-US probe that combines OCT optical components with an US transducer. The OCT optical components mainly consist of a single-mode fiber, a gradient index lens for light-beam focusing, and a right-angled prism for...
متن کاملTrimodality imaging system and intravascular endoscopic probe: combined optical coherence tomography, fluorescence imaging and ultrasound imaging.
In this Letter, we present a trimodality imaging system and an intravascular endoscopic probe for the detection of early-stage atherosclerotic plaques. The integrated system is able to acquire optical coherence tomography (OCT), fluorescence, and ultrasound images and simultaneously display them in real time. A trimodality intravascular endoscopic probe of 1.2 mm in diameter and 7 mm in length ...
متن کاملIntravascular Ultrasound Imaging of Coronary Arteries
Background. The purpose of this study was to evaluate the significance of the three-layered appearance of coronary arteries in adolescence and adults from intravascular ultrasound scans and to correlate these observations with histopathology. Methods and Results. Sixteen intact hearts were excised at autopsy from patients with no clinical history of coronary artery disease. The patients' ages r...
متن کاملIntravascular Ultrasound Imaging of Pulmonary Arteries*
Intravascular ultrasound imaging of the coronary artery has become an accepted standard in the evaluation of atherosclerotic lesions.1'8 It provides more accurate measurements of stenosis areas as well as a qualitative determination of the histologic components of atherosclerotic plaque.9"11 Recently, intravascular ultrasound of the pulmonary artery has been validated as a reliable and rapid me...
