A prototype water filled ultrasound string test object is presented for performance checks on Doppler ultrasound systems. The string motion produces realistic and reproducible Doppler wave forms on the system by means of a programmable stepper motor. Wave forms can be generated using a computer, and programmed into the device. The test object can be used to check Doppler calculation parameters, such as pulsatility index and resistance index, as well as range gate registration and wall filter… CONTINUE READING
