AIMS To assess the value of videodensitometric quantification of the coronary lumen after angioplasty by comparison to two other techniques of coronary artery lumen quantification. METHODS AND RESULTS Videodensitometric quantitative angiography, edge detection quantitative angiography and 30 MHz intracoronary ultrasound imaging were performed after successful balloon angioplasty in 161 patien...

Introduction Ultrasound is widely applied in the clinical field today, such as ultrasound contrast agent imaging, High Intensity Focused Ultrasound (HIFU), Extracorporeal Lithotripsy, sonodynamic therapy. Some of these have a close relation to the dynamic behavior of micro bubbles and that of a bubble cloud. In an ultrasound imaging, micro bubbles are used as contrast agents. Extracorporeal Foc...

By transmitting acoustic energy into the body and receiving and processing the returning reflections, phased-array ultrasound systems can generate images of internal organs and structures, map blood flow and tissue motion, and provide highly accurate blood velocity information. Historically, the large number of high-performance phased-array transmitters and receivers required to implement these...

HARMONIC IMAGING USING A MECHANICAL SECTOR, B-MODE ULTRASOUND SYSTEM by Danna Gurari ADVISOR: Dr. William D. Richard August 2005 Saint Louis Missouri An ultrasound imaging system includes transmitting ultrasound waves into a human body, collecting the reflections, manipulating the reflections, and then displaying them on computer screen as a grayscale image. The standard approach for ultrasound...

We report on the first study demonstrating the ability of a recently-developed, contrast-enhanced, ultrasound imaging method, referred to as cumulative phase delay imaging (CPDI), to image and quantify ultrasound contrast agent (UCA) kinetics. Unlike standard ultrasound tomography, which exploits changes in speed of sound and attenuation, CPDI is based on a marker specific to UCAs, thus enablin...

Ultrasound imaging, which is also called ultrasound scanning or sonography, is conducted by exposing part of the body to high-frequency sound waves to produce a visualization of the inside of the body. Ultrasound scanning is non-invasive, so it is usually painless. It is also widely available, easy-to-use and less expensive than other imaging methods. Because ultrasound imaging uses no ionizing...

Musculoskeletal ultrasound (US) has an increasingly important role in the assessment of spondyloarthritis (SpA) not only for its ability to detect synovial and tendon involvement but also for the accurate imaging of enthesitis, the clinical hallmark feature of SpA. As already known, most cases of enthesitis are subclinical in SpA and US is an effective technique used to detect them. Also, in ca...

 Ultrasound is a rapidly growing, non-invasive imaging modality that delivers detailed images for almost every medical specialty  Technology advancements enable ultrasound to provide diagnostic information to aid in surgical planning and minimally invasive procedures  Siemens has been pioneering ultrasound technology since the 1930s and offers an expansive product portfolio across cardiology...

Adrenal glands are paired endocrine glands located over the upper renal poles. Adrenal pathologies have various clinical presentations. They can coexist with the hyperfunction of individual cortical zones or the medulla, insufficiency of the adrenal cortex or retained normal hormonal function. The most common adrenal masses are tumors incidentally detected in imaging examinations (ultrasound, t...
