Ultrasonic Echography (B-Scan)

SKU: EDV-P5160300


The fundamental principles concerning the generation of ultrasonic B-scan images (brightness representation of the reflection amplitudes) are demonstrated with the aid of a simple test ob-ject. The experiment is executed with an ultrasonic echoscope in the pulse-echo-mode and the object is scanned manually. Then, the image quality and the most important image defects will be assessed.


• Exciting experiment to teach the basics of ultrasound imaging (echography)
• Diversified experiment with several measurement methods
• With the same setup A-scans can be performed
• Experiment setup can be upgraded for additional experiments in medical imaging and for echoscopy applications in material sciences
• Detailed experiment guide available


• Measure the 3 edge lengths of the test block with a vernier calliper and determine the time of flight of the sound for the various edge lengths of the test block with the aid of the measurement software.
• Calculate the sound velocity of the test block material and switch the measurement software (A-scan mode) to depth measurement.
• Produce two B-scans, one with the 1 MHz probe and one with the 2 MHz probe, with the aid of the measurement software (B-scan mode).
• Measure the depth and width of the echoes in the resulting images.
• Characterize the quality of the images in terms of their resolution and defects.
