EXPERIMENTS ULTRASOUND

Equipment set for experiments on geometric and wave-mechanical acoustics. Based on the piezo-effect discovered by the Curie brothers, an AC voltage is applied to a piezo-electric body causing it to oscillate. Sound waves can also be used to ... more

In solids, sound is propagated in the form of longitudinal and transverse waves. However, there is a considerable difference in the speed of the two types of sound waves, since longitudinal sound waves are determined by the elastic ... more

The periodic variations of density caused by an ultrasonic standing wave pattern in a liquid act as an optical grating for the diffraction of a monochromatic parallel light beam that is transmitted in the direction perpendicular ... more

Objective: Determining the internal dimensions in a model eye Sonography (medical ultrasound) is an imaging method that is also used in ophthalmology. Here, its largest importance lies in the area of biometry, in the measurement of distances ... more

Objective: Investigate the formation of an ultrasonic CT image and its relevant parameters X-ray CT, MRT and PET are computer-aided imaging methods used in medical diagnostics, industry and research. Processes such as radiation absorption ... more

Objective: Investigate the fundamental characteristics of stationary and laminar flowing liquids by using the ultrasonic Doppler method The applications of the Doppler Effect in the medical diagnostics are at the investigation of running ... more

Objective: Investigating a model arm Doppler sonography uses the Doppler Effect to assess whether structures (usually blood) are moving towards or away from the ultrasonic probe, and its relative velocity. By calculating the frequency shift ... more
