ULTRASOUND

These polished polyacrylate blocks are used to investigate multiple echoes and measure frequency-dependent attenuation. A 4 MHz transducer (U10017) is especially suitable for such measurements. An echo pattern comprising at least 3 echoes ... more

These polished polyacrylate cylinders are used to ascertain the speed of sound and the attenuation of ultrasonic waves in transparent acrylic. Measurements can be performed in reflection mode or through-transmission mode. Length : 40 mm, 80 ... more

The Acrylic Body with Drilled Holes is a polished polyacrylic block with bores of various diameters and varying distance from the surface. Experiment Topics: • Determine the speed of sound and the attenuation of ultrasonic signals ... more

This double vessel with a rubber membrane and pressure regulator is used to demonstrate movement of the cardiac wall by means of the time-motion technique. In the experiment the membrane vessel produces images similar to the cardiac wall of ... more

CT scanner for turning and moving samples for the purpose of generating tomographic images. All turning and movement is carried out by means of stepper motors. While the measurement is taking place, the scanner moves the sample backwards and ... more

Controller for operating the two stepper motors for the linear motion axis and the rotation axis of the CT scanner. Control of motion or direction of rotation, as well as linear speed and rotational velocity can be set manually or with a PC ... more

Black plastic cylinder with non-uniform absorption and speed of sound within its interior. With magnetic holder for attachment to the revolving stage of the CT scanner. In the case of ultrasonic tomography, two different measurement variables ... more

Sample trough for CT scanner made of thin transparent plastic. Includes several special fittings for attaching and connecting ultrasonic sensors to the sides of the trough. Since transparent acrylic exhibits a very low acoustic impedance step ... more

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

The ultrasonic Doppler probe with a frequency of 2 MHz has been specially developed for measurements on the arm phantom (order no. 1022331). The pen shape and the small sound area permit simple handling and lead to sufficient local resolution ... more

The Sound Heads are ultrasonic transmitter/receivers, which will operate at frequencies from 8 to 16 MHz, and emit a 2 mm wide beam. Designed for simple attachment to a digital caliper or the accessory Protractor Table, the Sound Heads become ... more
