Doppler ultrasound imaging test phantom 069A

liver

The Doppler Ultrasound Flow Phantom, when used with the model 769 Doppler Flow Pump, provides a complete solution for QA testing of doppler ultrasound devices. The two most common tests are sensitivity and velocity accuracy, but many other useful tests are also described in the literature. The phantom is a tissue-mimicking flow phantom with a blood-vessel-simulating, ultrasound-compatible tube that enters the phantom at an angle. The phantom has both a top and bottom scanning surface that allows testing at varying depths and angles of orientation. This makes the phantom suitable for testing both peripheral flow and deeper abdominal vessels. The phantom is filled with Zerdine® tissue mimicking gel with a speed of sound of 1540 m/s, an attenuation of 0.7 dB/cm/MHz and a backscatter contrast designed to match that of the liver. It is housed in rugged ABS plastic for added durability Features: Tissue-Equivalent Phantom Used in conjunction with CIRS Model 769 Varying tube depths for peripheral and abdominal vessel simulation Suitable for doppler sensitivity and velocity accuracy quality assurance testing Hard shell case
