Ultrasound close ultrasoundSound with a frequency greater than 20,000 Hz (20 kHz). waves have a frequency higher than the upper limit for human hearing – above 20,000 Hertz (Hz). Different ...

Other areas of interest in Medical Physics include the measurement of ionising radiation, magnetic resonance imaging, and the application of lasers, ultrasound, and other technologies which utilise ...

The practice of examining pregnant women using ultrasound is called obstetric sonography, and is widely used. In physics, 'ultrasound' refers to sound waves with a frequency too high for humans to ...

Targeted therapy uses microbubbles to transport medication directly to its destination.

Ultrasound can be used in industry to detect defects in metals. Materials can be tested for internal faults and cracks that could lead to the failure of a structure under certain conditions ...

Microbubbles that react to ultrasound are a particularly promising ... author of the study which was recently published in Nature Physics. Until now, nobody knew how the pores in the cell membrane ...

ETH Zurich researchers have investigated how microbubbles tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualised how tiny cyclic ...

Our interdisciplinary group, situated within both the Department of Physics and Biology at Concordia University, works on the development of an image-guided, targeted drug/gene delivery platform using ...

The Department of Medical Physics is actively developing new methods to address a wide range of imaging ... and other physicians to plan and monitor treatments involving radiation, ultrasound, and ...

Low-frequency ultrasound waves (39 kHz) can disrupt the cell membrane and trigger cell death in cancer cells. It is a relatively low-cost and non-invasive approach. Unlike normal cells ...
