Coherent plane-wave compounding for very high frame rate ultrasonography and transient elastography
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2009The emergence of ultrafast frame rates in ultrasonic imaging has been recently made possible by the development of new imaging modalities such as transient elastography.

Sound is a mechanical vibration of particles in a medium around an equilibrium position. Sonic waves require a medium of a molecular nature in order to propagate. The highest frequency sound audible to the human ear is 20,000 cycles per second or 20 kiloHertz (kHz). Sound waves above this frequency are described as ultrasound.

Endoscopic ultrasonography is a new and interesting technique. It is the only imaging technique that provides images of the gastrointestinal wall. Because of the high frequency used in EUS, it may provide high resolution images of gastrointestinal organs such as the pancreas. Although the equipment used for EUS is similar to that used for more familiar

Ultrasonography of the Pancreas
Radiologic Clinics of North America, 2012Although the pancreas is often thought of as an organ that is difficult to explore using ultrasound (US), because of its deep retroperitoneal location, with the appropriate technique it can be studied successfully in most patients. In this article, the authors discuss the use of available US techniques in the diagnosis of the most common pancreatic ...

Ultrasonography in Chondrocalcinosis
Joint Bone Spine, 2010Ultrasonography can visualize calcific deposits within soft tissues. The appearance and location of the deposits distinguishes articular chondrocalcinosis from other crystal deposition diseases. The most common findings are hyperechoic dots or lines running parallel to the joint surface, hyperechoic images within fibrous cartilage (menisci and ...

Ultrasonography in dermatology
JDDG: Journal der Deutschen Dermatologischen Gesellschaft, 2007SummaryUltrasonography is an essential tool for most medical specialties; training in its use is required for dermatology residency programs in Germany. Ultrasonography is a versatile, painless, low‐risk, non‐invasive procedure which can be done anywhere and easily repeated; it provides real‐time visual information about benign and malignant processes ...

Ultrasonography in gastroenterology
Scandinavian Journal of Gastroenterology, 2015Ultrasonography (US) is a safe and available real-time, high-resolution imaging method, which during the last decades has been increasingly integrated as a clinical tool in gastroenterology. New US applications have emerged with enforced data software and new technical solutions, including strain evaluation, three-dimensional imaging and use of ...

Ascites is usually not difficult to detect with ultrasonography because of its characteristic lack of echoes. However, minimal or lobulated collections of fluid or unusual distributions due to anatomical variations or associated pathological processes may create problems in diagnosis.
