Basics of Ultrasound (Ultrasound Experiment Set 1)

Physical and technical aspects of ultrasound technology and its application in medicine, natural sciences and engineering

This set can be used to conduct experiments on the basic physical and technical aspects of ultrasound technology and its application in medicine, natural sciences and engineering. Reference is made to both the introduction of the basic technical terms of the measurement technology of echoscopy and the essential physical properties of ultrasound. The GS200 ultrasound echoscope and the associated software are used to clearly illustrate the signal generation and signal processing from the transmission pulse through the reflection echo to the A-image and B-image. Essential technical terms such as transmission power, reception gain and time-dependent gain, probe frequency and coupling are elements of the experiments. In terms of physical properties, quantities such as amplitude, frequency dependence, speed of sound, attenuation and reflection coefficient are the subject of the investigations. The transition to ultrasound applications is achieved with the demonstration of the formation of an ultrasound B-image, the basics of non-destructive material testing and simple industrial applications such as level measurement. With additional accessories, the basic physics experiments can be expanded to include interesting topics such as spectral investigations, resonance effects and dispersion of ultrasonic waves.
