Preparing for the ARDMS SPI exam can feel overwhelming, but with the right resources and strategies, you can master ultrasound physics and pass with confidence. From understanding Doppler principles ...

Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that ...

Last year, tungsten diselenide (WSe2) had its magic moment. Two independent research groups discovered "magic angles" at which two atom-thin layers of the unique semiconductor, when twisted relative ...

A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...

Abstract: Automated ultrasound (US) image analysis is hindered by challenges stemming from low resolution, noise, and non-uniform grayscale distribution, which compromise image quality. While many ...

In patients with acute, intermediate-risk pulmonary embolism (PE), ultrasound-facilitated, catheter-directed fibrinolysis plus anticoagulation led to a lower risk of PE-related death, cardiopulmonary ...

April 24, 2026 • Scientists say they've made a key breakthrough that would allow robots to figure out complex tasks on their own, but experts say it raises questions about how much risk comes with ...
