Test Block (transparent)

The transparent test block made of homogeneous acrylic is especially suitable for echoscopy investigations. Acrylic is a material with medium acoustic attenuation, so that a sufficient penetration depth is achieved with all probes. The block has a group of differently sized defects at different depths, a large defect (acoustic shadow) and a double defect (resolution power). In this way fundamental knowledge can be gained of the determining of sound velocity, the echo method, acoustic shadows, multiple reflections, focus zones and the resolution power of ultrasound of different frequency.
