American CIRS 069 Doppler ultrasound blood flow simulator
Product model:
Brief description:The CIRS 069 Doppler ultrasound blood flow simulator is designed to simulate blood flow in tissue simulation phantoms and can be used to perform quality assurance testing of Doppler ultrasound equipment. Two tests that are very common are sensitivity and speed accuracy, but many other useful tests are described in the literature (see References).

Detailed introduction
USACIRS 069Doppler ultrasound blood flow simulator
Product introduction:
The CIRS 069 Doppler ultrasound blood flow simulator is designed to simulate blood flow in tissue simulation phantoms and can be used to perform quality assurance testing of Doppler ultrasound equipment. Two tests that are very common are sensitivity and speed accuracy, but many other useful tests are described in the literature (see References).
The CIRS 069 Doppler Ultrasound Blood Flow Simulator includes a blood vessel simulation ultrasound-compatible tube that mimics a human blood flow model and enters the model at an angle. The phantom has both top and bottom scanning surfaces, allowing testing at different depth and orientation angles. This makes the phantom suitable for testing peripheral blood flow and deeper abdominal vessels. The phantom was filled with Zerdine® tissue-mimetic gel with an attenuation of 1540 m/s, 0.7 dB/cm/MHz and a backscatter contrast designed to match the acoustic velocity of the liver. It is housed in sturdy ABS plastic for added durability. Customers wishing to combine B-mode quality assurance capabilities with Doppler testing may request custom phantoms to include wire, grayscale and anechoic targets.
USACIRS 069 Doppler ultrasound blood flow simulator product features:
Peristaltic pumps can provideFlow rate of 0.5 to 12.5ml/s, which means the average flow rate is 2-70cm/s. (Due to the influence of laminar flow and pulsating flow, the peak flow rate will be 2-4 times greater than the average flow rate).
pre-filledReservoir for CIRS blood simulant fluid. Replacement fluid can be ordered separately.
Pulsation dampers convert pulsating flow from a peristaltic pump into a constant flow rate.
Convenient color-coded tube quick disconnect fittings
The convenient hard-shell carrying case design keeps the entire system pre-configured inside the case.
