To determine how the ultrasonic energy scattered from flowing blood depends on the hematocrit, the rms amplitude of the audio Doppler signal from a range gated, pulsed Doppler ultrasonic flowmeter was measured for hematocrits ranging from 0.01 to 80%. For all investigated frequencies (5–27 MHz), the signal power, the square of the rms amplitude, was… CONTINUE READING
