- A Cardiologist Uses An Ultrasound Scanner At The Frequency Of 3 2 Mhz That Can Detect A Doppler Shift As Small As 0 1 Kh 1 (382.81 KiB) Viewed 24 times
A cardiologist uses an ultrasound scanner at the frequency of 3.2 MHz that can detect a Doppler shift as small as 0.1 kHz. Use that the average speed of sound in tissue is 1550 m/s. 5pts 1. Determine the smallest blood flow velocity that can be detected by this device. Show the physics approach and all steps. II. How does this velocity compare to the speed of blood in different blood vessels from capillaries to arteries. The speed of blood ranges from 0.5 cm/s to 50 cm/s in capillaries to arteries, respectively? Can this low frequency shift map the blood flow in capillaries?
