A blood flowmeter measures the difference in upstream and downstream transit times for short bursts of 10-MHz ultrasound with the two transducers required mounted in a catheter tip. This instrument can measure flow as small as 0.1 cms, with a response time of 5 ms. A method is proposed to measure the cross-sectional area of the vessel so that the volume flow rate and the flow velocity can be determined. Author
