Ultrasound Doppler Flow Directional Discrimination Device ATS 527
Model 527 rubber-based tissue mimicking phantom is designed to test color Doppler flow imaging systems. This phantom monitors the ability of the system to discriminated the direction of flow in small vessels, of close proximity, at varying depths. The phantom contains four pairs of 2 mm flow channels. The edge-to-edge spacing between the flow channels within each pair progressively increases from 1 mm to 4 mm. If greater distances are desired, a combination of two flow channel pairs can be used. A fixed-angle scan surface maintains a constant angle between the sound beam and the test fluid flowing through the phantom at 18° or 56° permitting continuous scanning at depths ranging from 3 to 17 cm.
