INTRAVASCULAR ULTRASOUND TECHNIQUES
The Journal of the Acoustical Society of America, 2013Intravascular ultrasound techniques provide for intravascular imaging using contrast agents and nonlinear techniques. An ultrasound imaging device for detecting internal properties of a target body comprises an ultrasound transducer positioned at a distal end portion of a catheter, for transmitting excitation pulses and for receiving echo signals.

A Novel Synchronous Micro Motor for Intravascular Ultrasound Imaging
IEEE Transactions on Biomedical Engineering, 2019Objective: Intravascular ultrasound (IVUS) is an important method for evaluating lumen dimensions and guiding intervention. However, the current IVUS catheter using a proximal motor and flexible drive shaft is easily rotated at an unstable speed when it ...

Clinical Perspectives of Intravascular Ultrasound
Echocardiography, 1990The history of intravascular ultrasound imaging, recent developments in catheter technology, and the initial in vivo experience are reviewed. Additionally, the article also discusses the potential applications of intravascular ultrasound imaging in coronary and peripheral arterial atherosclerosis, hypertension, pulmonary arterial disorders, valvular ...

Intravascular ultrasound in interventional radiology
European Radiology, 2000Intravascular ultrasound (IVUS) imaging provides useful additional information to X-ray angiography in selected cases of balloon angioplasty and stent placement with complex vascular anatomy and unclear findings at angiography. It facilitates accurate measurements of the vessel dimensions and reveals the extent of the disease for the selection of ...

Coronary angiography and intravascular ultrasound
The American Journal of Cardiology, 2001Clinicians have long used the size of the lumen and the angiogram as a predictor of coronary events. However, cardiovascular disease is not a disease of the lumen but a disease of the vessel wall. In early stages, atherosclerosis outwardly remodels the external elastic membrane; only late in the disease process does luminal narrowing occur, enabling ...

Intravascular Ultrasound Imaging
Archives of Surgery, 1994Intravascular Ultrasound Imaging contains a clear overview of the basics of intravascular ultrasound physics with helpful details to avoid problems when starting out with this imaging modality. The authors present how-to techniques and discuss the advantages and pitfalls of three-dimensional reconstruction and its future applications.
