Echogenicity quantitative test system for an echogenic medical device

An echogenicity quantitative test system for a sample echogenic medical device, comprising:

• a test fixture including an ultrasonic probe, a probe holder having a first guide rod, a probe clamp configured to hold the ultrasonic probe and movably held on the first guide rod;
• and
• a holder having a second guide rod and a sample clamp configured to hold the sample echogenic medical device, the sample clamp being movably held on the second guide rod, the first guide rod and the second guide rod being movably disposed relative to the test fixture;
• wherein the test fixture comprises an open frame, and further including a container configured to hold a test medium in which the sample echogenic medical device is located during the test.
