Central to this calculation is the assumption of a linearly propagating ultrasound wave with minimal nonlinear distortion. This assumption was verified by COMSOL simulations and hydrophone ...

Ultrasound unlocks a safer, greener way to make hydrogels Researchers develop a method that could revolutionize biomedical and environmental applications Date: May 9, 2025 Source: McGill ...

Researchers at McGill University, in collaboration with Polytechnique Montréal, pioneered a new way to create hydrogels using ultrasound, eliminating the need for toxic chemical initiators.

5.5, COMSOL AB, Sweden). The 3D model consisted of a transducer ... To examine the irradiation properties of ultrasound waves traveling through our designed waveguide, we measured the acoustic ...

To develop our design, we can use a COMSOL model but without some validation ... different imaging techniques such as X-ray (computed tomography / fluoroscopy) and ultrasound imaging. Tissue-mimicking ...

It involves first applying ultrasound gel, then going over the treatment area in three passes at different depths: two millimeters and three and a half millimeters. "The deeper you go, the deeper ...

ABSTRACT: In many applications in aluminium industry, the number of inclusion-critical products increases and the quality of those products depend on the inclusion concentration and size. In order to ...

Ultrasound works by sending sound waves through the body. Doctors can recommend ultrasound therapy to treat pain. It may work best alongside other treatments. Many people know ultrasound as an ...

A liver ultrasound is one of a few tests your doctor can order if they want to check your liver. An ultrasound scan (also known as sonography) is a noninvasive procedure. It captures live images ...

Abstract: An array laser ultrasound method for the detection of air holes in aluminium blocks is proposed. A two-dimensional transient laser ultrasound force-solid coupling model is established under ...
