  • ECHOGENICITY QUANTITATIVE TEST SYSTEM FOR AN ECHOGENIC MEDICAL DEVICE
    Publication number: 20210055414
    Abstract: An echogenicity quantitative test system for a sample echogenic medical device includes a fixture into which the echogenic medical device is positioned in relation to an ultrasonic probe connected with an ultrasound diagnostic device. The fixture includes a frame; a probe holder having a first guide rod and a probe clamp configured to hold the ultrasonic probe and movably held on the first guide rod, and a sample holder having a second guide rod and a sample clamp configured to hold the medical device sample. The sample clamp is movably held on the second guide rod. The frame may include guide rails, and the first guide rod and the second guide rod are movably disposed in the guide rails so as to allow for adjustments to the relative positions of the ultrasonic probe and the sample echogenic medical device.
