Superresolution in ultrasound imaging

2009 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2009
Ultrasound techniques for imaging objects significantly smaller than the source wavelength are investigated. The present overview explains two such methods that are being investigated in our laboratory. The first method is designed for detecting scattering using an unfocused ultrasound field created from a continuously-driven source array.

Ultrasound imaging in spondyloarthropathies

Best Practice & Research Clinical Rheumatology, 2010
Through recent technological advances, ultrasound allows high-resolution visualisation of inflammatory and destructive changes in tendon and joint structures. Over the last few years, the added value of the use of ultrasound for evaluating entheseal involvement in spondyloarthritis (SpA) patients has been demonstrated.

Ultrasound imaging of pneumonia

Ultrasound in Medicine & Biology, 1995
One hundred forty-three consecutive patients with clinically and radiologically confirmed pneumonia were examined by ultrasound. In 127 cases (88.8%), a consolidation could be visualised in the sonogram. Eight patients (5.6%) had a pleural effusion only. The remaining eight (5.6%) had no pathological findings.

Enhanced ultrasound imaging

Gastrointestinal Endoscopy, 2011
The American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee provides reviews of emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methodology is used, with MEDLINE and PubMed literature searches to identify pertinent clinical studies on the topic.

Ultrasound imaging for the rheumatologist. XV. Ultrasound imaging in vasculitis.

Clinical and experimental rheumatology, 2008
Over the last few years, a large number of studies have emphasized the fundamental role of ultrasonography (US) in the clinical evaluation of patients affected by rheumatic disorders. However, not all rheumatic diseases have been studied by US. To date, very few reports exist on the use of US in the assessment of articular, periarticular structures and

Ultrasound imaging for the rheumatologist VIII. Ultrasound imaging in osteoarthritis.

Clinical and experimental rheumatology, 2007
The present review provides an update of the available data and discusses research issues relating to ultrasound (US) imaging in osteoarthritis (OA). Currently, the principal indications for using US in OA include: delineation of changes within articular cartilage (AC) and demonstration of synovial and adjacent soft tissue pathology together with ...

Ultrasound imaging for the rheumatologist IX. Ultrasound imaging in spondyloarthritis.

Clinical and experimental rheumatology, 2007
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

Cerebrovascular Ultrasound Imaging

Radiologic Clinics of North America, 1988
Advancements in technology have brought noninvasive diagnosis of cerebrovascular disease to a high level of accuracy in a relatively short period of time. Conventional duplex sonography allows precise vessel localization and Doppler quantification. The further refinement of color flow imaging promises to simplify the examination and add considerable ...

Ultrasound imaging of the kidneys

British Journal of Hospital Medicine, 2008
A wide range of disorders affect the kidneys and ultrasonography is often the modality of choice in the initial assessment. This article reviews the ultrasound appearances of some common adult kidney disorders encountered in daily practice.

Ultrasound imaging and atherogenesis

The International Journal of Cardiac Imaging, 1989
The in vivo detection of early atherosclerosis remains a problem. First, atherogenesis is a process with an insidious onset and course. Once clinical signs and symptoms have developed the lesion usually is in an advanced stage. Second, the detection of early atherosclerotic lesions creates the problem of distinguishing between almost natural, age ...
