What is pulse repetition period in ultrasound?

Pulse repetition frequency (PRF) indicates the number of ultrasound pulses emitted by the transducer over a designated period of time. It is typically measured as cycles per second or hertz (Hz). In medical ultrasound the typically used range of PRF varies between 1 and 10 kHz ¹.

How do you calculate pulse repetition period?

PRT = pulse repetition time. PRT has units of time and is commonly expressed in ms. PRT is the interval between the start of one pulse and the start of another. PRT is also equal to the sum, PRT = PW+RT.

What does PRF mean in ultrasound?

A change in phase translates to a change in frequency—e.g. when the returning signal is compared to the emitted, returning wave tops will not correspond to the emitted wave tops because the distance between the tops has changed. The number of these pulses per second is called the pulse repetition frequency (PRF).

What is the normal range of pulse repetition rates?

What is the normal range of pulse repetition rates? 500 to 2,000 pps. The pulse repetition rate is how many pulses are created in a unit of time.
