Coronary flow reserve (CFR) is a key sign of coronary artery disease, namely how the coronary arteries that feed blood to the heart may adapt to various physiological situations such as exercise, ...

Left: 3D power-Doppler volumes overlaid on anatomical volumes of the myocardium in the left-anterior descending artery. Right: Absolute flow velocities estimated by 4D ultrafast ultrasound flow ...

Ultrafast functional Doppler ultrasound (fUS) is based on the principles of conventional Doppler ultrasonography but operates at an extremely fast frame rate. This significantly improves ...

Philips has upgraded its smartphone-controlled hand-held ultrasound system, adding pulse wave Doppler support to help clinicians examine real-time blood flow across a range of diagnostic applications.

Ultrasound imaging isn’t just about moving a probe—it’s about understanding the physics that make every pixel possible. From wave mechanics to Doppler concepts, mastering these principles helps ...
