Ultrasonography in GCA assessment

GCA: A Massively Parallel Model

We had introduced the massively parallel global cellular automata (GCA) model. Parallel algorithms derived from applications can be mapped straight forward onto this model. In this model a cell in the cell field is dynamically connected (access pattern, dynamic neighbourhood) to other cells. The model can be implemented by pointers stored in the cell state. Via these pointers, each cell has rea...

Rheumatoid Arthritis Assessment with Ultrasonography

Musculoskeletal ultrasound is a rapidly growing imaging modality used for the investigation and management of musculoskeletal disorders. The first report of musculoskeletal ultrasonography was published in 1958 by K. T. Dussik who measured the acoustic attenuation of articular and periarticular tissues including skin, adipose tissue, muscle, tendon, articular capsule, articular cartilage and bo...

Ultrasonography for Noninvasive Assessment of Portal Hypertension

Portal hypertension is a major pathophysiology in patients with cirrhosis. Portal pressure is the gold standard to evaluate the severity of portal hypertension, and radiological intervention is the only procedure for pressure measurement. Ultrasound (US) is a simple and noninvasive imaging modality available worldwide. B-mode imaging allows broad applications for patients to detect and characte...

Scrotal Ultrasonography in the Assessment of Subfertile Males

Subfertility is defined as a failure to conceive after one year of unprotected regular sexual intercourse. A prospective study was conducted to identity the role of ultrasonography in assessing the cause of male subfertility in a Sri Lankan population. The objective of the study was to identify the role of ultrasonography in assessing the cause of male subfertility in a Sri Lankan population. T...
