  • Phantom design for testing of Doppler ultrasound function
    Patent number: 10085725
    Abstract: A Doppler phantom includes a first reservoir, a second reservoir, a fluid line coupling the first and second reservoirs, a pressure line coupling the first and second reservoirs, and a tissue mimicking material surrounding at least the fluid line. The phantom can be positioned in first and second positions, where the first reservoir defines an elevated reservoir and the second reservoir defines a lower reservoir in the first position, where the second reservoir defines the elevated reservoir and the first reservoir defines the lower reservoir in the second position. The fluid line provides a path for fluid to travel from the elevated reservoir to the lower reservoir via gravity in either of the first or second positions, and the pressure line provides a path for gas to transfer from the lower reservoir to the elevated reservoir while the fluid travels in either of the first or second positions.
