Resonant ultrasound spectroscopy (RUS) is a laboratory technique used in geology and material science to measure fundamental material properties involving elasticity. This technique relies on the fact that solid objects have natural frequencies at which they vibrate when mechanically excited.
JDMS publishes peer-reviewed manuscripts supporting the translational use of medical ultrasound for diagnosis, intervention, and other clinical applications by a sonographer, sonologist, or other health care provider. The JDMS provides research, clinical, and educational content for all specialties, including but not limited to abdominal, women ...
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
Ultrasound energy, simply known as ultrasound, is a type of mechanical energy called sound characterized by vibrating or moving particles within a medium. Ultrasound is distinguished by vibrations with a frequency greater than 20,000 Hz, compared to audible sounds that humans typically hear with frequencies between 20 and 20,000 Hz.
Participation in the education of medical physics students and organisation of medical physics residency programmes. Health technology assessment (HTA): Taking responsibility for the physics component of health technology assessments related to medical radiological devices and /or the medical uses of radioactive substances/sources.
The speckle effect is a result of the interference of many waves of the same frequency, having different phases and amplitudes, which add together to give a resultant wave whose amplitude, and therefore intensity, varies randomly.

Isochoic wave is a term used in ultrasound. Substances of a different medium are called isochoic if waves travel through them at the same speed. Isochoic in ultrasound means that two structures have the same echogenicity in 2D mode (B-mode).
