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 ...

In this episode of the Physics World Weekly podcast, we explore how computational physics is being used to develop new quantum materials; and we look at how ultrasound can help detect breast cancer.

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 ...

But recent developments in medical physics have introduced ultrasound-activated microbubbles that temporarily open the BBB, allowing targeted drug delivery. This innovation could revolutionize ...

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 ...

“Ultrasound can also serve as an abiotic stressor ... The study was published in the KeAi journal Food Physics. Contact the author: Haile Ma, School of Food and Biological Engineering, Institute ...

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 ...
