If the maximum unambiguous velocity measurable by the pulsed Doppler system is 80 cm/s at an angle of 60°, which corresponds to a Doppler frequency shift of 4 kHz, what would be the required Pulse Repetition Frequency (PRF) for the system?

An ultrasound beam travels through a three-layer medium: Medium A, Speed = 1540 m/s Medium B, Speed = 2310 m/s Medium C, Speed = 1540 m/s. All interfaces in this layered medium run parallel to one another. The angle of incidence of the ultrasound at the interface between medium A and medium B is 30° from the interface normal. What angle will the ultrasound beam propagate in medium C?

An ultrasound beam with a frequency of 5 MHz passes through three different tissues with the following characteristics: Tissue A: 2 cm thick with attenuation coefficient 0.5 dB/cm @ 5MHz Tissue B: 3 cm thick with attenuation coefficient 0.7 dB/cm @ 5MHz Tissue C: 1 cm thick with attenuation coefficient 1.2 dB/cm @ 5MHz If the initial intensity of the ultrasound beam is 100 mW/cm², what is the approximate intensity after passing through all three tissues? The reflection at each interface is not considered here.
