3D volumetric ultrasound is shown to be of tremendous value particularly in gynaecology and associated clinical areas. The combination of modern 3D technology and high resolution transvaginal scanning provides increased anatomical and clinical detail. Furthermore it offers considerable benefits from a practical point of view. Nevertheless, its role in gynaecological ultrasound has yet to be ful...

Advances in field of ultrasound over the past twenty years have generated increasing interest in utilizing the technology in neuromuscular assessment and diagnosis. High-resolution ultrasound offers a noninvasive, realtime, static and dynamic examination of the peripheral nervous system, yielding information which complements the neurological examination, electrodiagnostic testing (EDX), and ot...

A new two-dimensional ultrasound imaging system capable of producing high resolution tomographic images of the heart in real time has been developed. This system relies on phased array principles to rapidly steer the ultrasound beam through the structures under investigation. A hand-held linear array of 16 ultrasound transducers with overall dimensions of 14 mm at the site of contanct may be re...

Intracardiac Echocardiography Ultrasound technology has progressed rapidly over the past several years, leading to significant miniaturization of transducer design. The original catheter-based transducers, known as intravascular ultrasound (IVUS) catheters, are high frequency (20 to 40 MHz) and are used to image the walls of coronary arteries and other small vessels. They contain a single ultra...

The vitreous body is nearly transparent both optically and ultrasonically. Conventional 10- to 12-MHz diagnostic ultrasound can detect vitreous inhomogeneities at high gain settings, but has limited resolution and sensitivity, especially outside the fixed focal zone near the retina. To improve visualization of faint intravitreal fluid/gel interfaces, the authors fabricated a spherically curved ...

OBJECTIVE To evaluate the role of annular ciliary body detachment in the development of postoperative angle-closure glaucoma. DESIGN Case series. SETTING Tertiary care glaucoma referral center. METHODS High-resolution, anterior segment ultrasound biomicroscopy, ophthalmoscopy, and B-scan ultrasonography were performed on 6 eyes of 6 patients with a clinical diagnosis of postoperative mali...

To check or to prevent failures in ultrasound medical systems, some tests should be scheduled for both clinical suitability and technical functionality evaluation: among them, image quality assurance tests performed by technicians through ultrasound phantoms are widespread today and their results depend on issues related to scanner settings as well as phantom features and operator experience. I...

OBJECTIVES To investigate the pathogenesis of pressure ulcers utilizing high-resolution ultrasound and to explore the utility of this technology for the detection of incipient pressure ulcers prior to visual clinical signs. DESIGN An observational prospective study comparing high-resolution ultrasound images obtained from 119 long-term-care facility residents determined to be at risk for pres...
