Researchers have shown for the first time that patterns of ultrasound signals can be used to identify whether or not cancer has started to spread in melanoma patients, and to what extent. The discovery enables doctors to decide on how much surgery, if any, is required and to predict the patient's probable survival.

Ultrasound can be used to make an appropriate decision regarding care for patients with rheumatic conditions involving the hands and feet, according to a study performed at St. Joseph’s Healthcare/McMaster University in Hamilton, Canada.

Computer engineers at Washington University in St. Louis are bringing the minimalist approach to medical care and computing by coupling USB-based ultrasound probe technology with a smartphone, enabling a compact, mobile computational platform and a medical imaging device that fits in the palm of a hand.

In recent years HIFU has been widely used for the treatment of solid tumors, such as liver tumor, bone tumor, and breast cancer. The mechanism for therapeutic actions of HIFU includes thermal effects and non-thermal effects with the latter dominated by cavitational effects.

The use of ultrasound waves for deep vein thrombosis (DVT) may help dissolve blood clots in less time than using clot-busting drugs alone, according to researchers at Emory University. The study will be presented Sunday, Nov. 23, 2008 at the annual VEITHsymposium in New York City.

Doctors use diagnostic sonography or ultrasound to visualise organs and other internal structures of the human body. Dutch researcher Koos Huijssen has developed a computer model that can predict the sound transmission of improved designs for ultrasound instruments.

In a twist on nontraditional uses of ultrasound, a group of neuroscientists at Arizona State University has developed pulsed ultrasound techniques that can remotely stimulate brain circuit activity.

International studies indicate that there is an association between examiner qualifications and device quality on the one hand, and detection rates of ultrasound screening tests in pregnancy on the other. However, it is unclear which minimum preconditions must be fulfilled in order to achieve sufficiently high detection rates for major foetal abnormalities.

Siemens Healthcare unveils the ACUSON SC2000™ volume imaging ultrasound system, the first system in the world to acquire non-stitched, real-time full-volume 3D images of the heart in one single heart cycle, during the 19th Annual Session of the American Society of Echocardiography (ASE) in Toronto, June 7-11.

The April 2008 issue of the Journal of Ultrasound in Medicine (JUM) includes an important special feature, the “AIUM Consensus Report on Potential Bioeffects of Diagnostic Ultrasound,” which addresses issues related to the bioeffects of diagnostic ultrasound and is intended for use in assessing its risks and benefits.

Color Doppler ultrasound, not CT, should be the first imaging examination for adult patients with suspected acute appendicitis, a new study emphasi

Brightly colored dyes such as the shimmering Congo Red commonly used in silk clothing manufacture are notoriously difficult to dispose of in an environmentally benign way.
