A new ultrasound technique using transcranial Doppler and duplex carotid ultrasound can accurately measure carotid artery blockages, reducing the need for cerebral angiography and associated risks. This method is a safer alternative for assessing blockage before deciding on surgery for stroke prevention.
A new study by German neurologists found that transcranial color-coded duplex sonography (TCDS) is 90% effective in distinguishing between ischemic and hemorrhagic strokes under emergency treatment conditions. TCDS can accurately diagnose stroke type in most cases, making it a fast and reliable option for acute stroke treatment.
A new ultrasound technique has been developed to improve food inspection by spotting defects as small as 10 microns in size, which is one-fifth the diameter of a human hair. The technology allows for the non-destructive detection of voids, air, water, or protein strands in plastic-sealed containers.
Young physicians who undergo formal training in ultrasound testing on pregnant women perform better than those without such training, according to a Johns Hopkins study. The formal training program includes a checklist of sonographic skills and evaluates residents' progress through practical exams.
The new sonochemical synthesis technique creates highly magnetic metal powders with clusters of a few hundred atoms, exhibiting superparamagnetic behavior. These powders have the potential to be used in various applications including information storage, audio reproduction, and magnetic sealing.
The UW-Siemens image processor enables the creation of multiple diagnostic applications, increasing clinical efficiency. It allows for real-time panoramic imaging of internal organs and their surroundings, revolutionizing diagnosis and treatment.
Researchers have invented a new digitally encoded plastic transparency to test the accuracy of ultrasound scanners. The new phantom is more accurate and works faster than current phantoms, which are cumbersome hand-built blocks made of various tissue-mimicking materials.
The new technology uses parallel computing to analyze reflected sound waves, creating three-dimensional images quickly enough for clinicians to view a whole human heart as it beats. The system also enables doctors to electronically dissect and display selected slices of medical interest on a computer screen.
