When the depth of view is deep, the PRP is _____.

Explanation:
Pulse repetition period is the time between successive ultrasound pulses. When you image at a greater depth, the emitted pulse must travel farther and echoes from the deepest structures take longer to return. That longer round-trip time means the next pulse can’t be sent until more time has passed, so the interval between pulses becomes longer. The relationship is PRP ≈ 2 × depth / speed of sound in tissue (about 1540 m/s). Therefore, deeper imaging yields a longer PRP. (As a side note, PRP and pulse repetition frequency are reciprocals, so a longer PRP means a lower PRF and a slower frame rate.)
