In a major breakthrough, scientists have observed electrons in graphene flowing like a nearly frictionless liquid, defying a core law of physics. This exotic quantum state not only reveals new ...

Abstract: The development of fully noninvasive, transcranial functional ultrasound (fUS) would increase the translatability and clinical potential of this neuroimaging modality. Unfortunately, ...

Abstract: High-frequency ultrasound (HFUS; >30 MHz) Doppler imaging has been widely used in the imaging of small animals and humans because of its high resolution. Vector Doppler imaging (VDI) has ...

MELBOURNE, Australia — PET/CT scanning should be considered as an alternative to Doppler ultrasound in the diagnosis of cranial giant cell arteritis (GCA), as technological advances mean the imaging ...

A project at USC Keck School of Medicine and Caltech has developed an imaging platform offering improved views of both blood vessels and tissue. Described in Nature Biomedical Engineering, the new ...

Cancer is one of the leading causes of death in the U.S., second only to heart disease. But a new cancer treatment method from CU Boulder researchers uses sound waves to soften tumors and could be a ...

Amid a rise in the use of cosmetic fillers -- commonly injected in the face for anti-aging effects -- Doppler high-frequency ultrasound (HFUS) picked up "highly variable" findings in filler-related ...

Samsung Healthcare unveiled a new ultrasound system this week designed to boost diagnostic accuracy and efficiency. The system, named the R20, finally brings the full weight of Samsung Electronics’ AI ...

Ask 10 Seattleites what they think Doppler is, and the answers will vary from animal to monster to something about radar or wave frequencies. None of them would be totally wrong, and it all adds to ...
