The Models 524 and 525 tissue mimicking Doppler flow phantoms contain four flow channels simulating superficial vasculature. The simulated vessels are located 15 mm below the scan surface. Built-in scanning wells are provided to permit the use of water or a low viscosity gel as acoustic coupling agents.
The two models are distinguished by different structures. The Model 524 has four constant diameter channels, 2, 4, 6 and 8 mm. The Model 525 mimics a vascular stenosis by narrowing at the middle from an entrance diameter of 8 mm to varying stenosis levels (0, 50, 75 and 90%).
If the user requires depths greater than 15 mm, we recommend the use of our Model 528 scanning wedge. The wedge is constructed of the same tissue mimicking material as the Doppler flow phantoms and provides an additional 50 mm of scanning depth.
Key Tests with Models 524 & 525:
When used with Model 769, Doppler Flow Pump, the follow tests can be performed:
- Flow Velocity
- Maximum Penetration
- Flow Location
- Demonstration of the effects of stenosis (Model 525)
