Mayo Clinic researchers use ultrasound to describe subtle heart muscle motions
By using sound waves Mayo Clinic researchers have described subtle changes in the motion of the heart that are measurable by ultrasound and may improve understanding of heart function, and possibly be a noninvasive aid in predicting impending heart damage including heart attacks. view more (2005-08-01)
Novel computer model for blood flow could help doctors predict arterial disease
A unique computer model of how blood flows in human arteries has been developed by researchers in the UK. The model could help doctors understand the stresses that blood places on the walls of vessels and provide new insights into vascular disease. The work has been carried out by Dr Yun Xu together with Dr Simon Thom and Professor Alun Hughes at... view more... (2000-10-19)
Image Velocity Estimation In Echocardiographs
BACKGROUND There are many instances in which a subject in an image is moving, and it is necessary to track the subject as it moves from frame to frame; this movement is known as optical flow or image velocity. Such measurement of optical flow may be done to improve the image encoding efficiency, or allow enhancement of the display of the movement... view more... (2005-04-26)
Noise-Immune Stethoscope Helps Medics Hear Vital Signs in Loud Environments
A new type of stethoscope enables doctors to hear the sounds of the body in extremely loud situations, such as during the transportation of wounded soldiers in Blackhawk helicopters. view more (2006-11-29)
New treatment eliminates heel pain caused by plantar fasciitis
Combining an ultrasound-guided technique with steroid injection is 95 percent effective at relieving the common and painful foot problem called plantar fasciitis, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). view more (2008-12-01)
Autonomous robot detects shrapnel
Bioengineers at Duke University have developed a laboratory robot that can successfully locate tiny pieces of metal within flesh and guide a needle to its exact location -- all without the need for human assistance. view more (2009-06-19)
Diagnostic strategy may help determine stage of lung cancer more accurately
A preoperative testing strategy combining two procedures may help improve the accuracy of determining the stage of lung cancer, according to an article in the August 24/31 issue of JAMA. view more (2005-08-24)
From securing stealth to ensuring health
A material used to protect submarines from sonar detection is the latest technological breakthrough in ensuring the safe and effective dose of ultrasound in medicine. Practitioners and thousands of patients in physiotherapy departments worldwide will benefit from the latest technology, which will ensure a step forward in the reliability of... view more...

Successful neurosurgery with transcranial MR-guided high-intensity focused ultrasound
The Magnetic Resonance Center of the University Children's Hospital Zurich has achieved a world first break through in MR-guided, non-invasive neurosurgery. view more (2009-06-23)
Prenatal sonography has no effect on the intellectual capacity of the developing child
Scientists carrying out a major epidemiological study at Karolinska Institutet and Uppsala University have discovered that there is no clear correlation between routine ultrasonic scans and intellectual impairment. "Fears have been expressed that sonography can lead to diminished intellectual capacity," explains Helle Kieler, research... view more... (2005-04-13)
New procedure safer for detecting fetal anemia
An innovative, non invasive ultrasound procedure to detect anemia in the fetus during high risk pregnancy is safer for patients. view more (2006-07-13)
Can EUS elastography help distinguish benign from malignant tissue?
A major limitation of endoscopic ultrasound (EUS) examination is its limited capacity to determine the exact nature of a lesion. view more (2009-04-15)
Duke engineers developing ultrasound devices combining 3-D imaging with therapeutic heating
Duke University engineers are developing technology that may enable physicians to someday use high frequency ultrasound waves both to visualize the heart's interior in three dimensions and then selectively destroy heart tissue with heat to correct arrhythmias. view more (2005-11-07)
Engineers develop way of detecting problems with artificial hip joints
A more efficient way of detecting loosened artificial hip implants, which affect thousands of people every year, has been developed. view more (2007-08-03)
An Individualized Approach to Breast Cancer Treatment
Not all breast cancers are the same, and not all will have fatal consequences. But because clinicians find it difficult to accurately determine which tumors will metastasize, many patients do not receive the therapy fits their disease. view more (2009-01-27)
Tracing agent, ultrasound combo helps test cancer therapy's effectiveness
An inexpensive tracing agent used in combination with ultrasound can pinpoint how effectively drugs targeting pancreatic cancer work, researchers at UT Southwestern Medical Center have demonstrated for the first time. view more (2007-01-10)
High-Intensity Ultrasound May Launch an Attack on Cancer, Wherever it Lurks
An intense form of ultrasound that shakes a tumor until its cells start to leak can trigger an "alarm" that enlists immune defenses against the cancerous invasion, according to a study led by researchers at Duke University's Pratt School of Engineering. view more (2007-08-08)
First acoustic metamaterial 'superlens' created by U. of I. researchers
A team of researchers at the University of Illinois has created the world's first acoustic "superlens," an innovation that could have practical implications for high-resolution ultrasound imaging, non-destructive structural testing of buildings and bridges, and novel underwater stealth technology. view more (2009-06-25)
Screening to help prevent stroke in kids increases, but limited access a problem
The number of children with a certain blood disorder undergoing an ultrasound to help prevent stroke is up significantly in the past 10 years since the publication of a major study showing its benefits. view more (2009-04-14)
Aircraft damage detected by heat and sound
Two new techniques that detect hidden and potentially disastrous damage to aircraft materials are published today in the Institute of Physics journal, Measurement Science and Technology. Researchers at the University of Bath have developed a method using sound waves to examine aircraft parts and look for damage, while another group of researchers... view more... (2001-01-18)
