2024年6月8日 · 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 pulses …

Pulse-repetition frequency (PRF) is the number of times a pulsed activity occurs every second. This is similar to cycle per second used to describe other types of waveforms. PRF is inversely …

2016年3月5日 · Pulse repetition frequency: A noteworthy number shown on the display is the pulse repetition frequency (PRF). The PRF for the color flow image is shown at the left of the …

Variable color-write priority, gray-scale gain, pulse repetition frequency (PRF), and spectral Doppler gain were varied. They observed that machine settings effect the appearance of the …

2022年2月23日 · The PRF is the rate of pulses transmitted consecutively, not to be confused with the ultrasound frequency of those pulses. The measureable blood flow velocity depends on …

Aliasing arises when the Doppler shift of the moving blood is greater than the Nyquist frequency (Nyquist frequency = pulse repetition frequency (PRF)/2). Aliasing is useful because it enables …

Pulse repetition frequency (PRF) The number of ultrasound pulses sent per second is called pulse repetition frequency (PRF). PRF is determined by the speed of sound and the distance it must …

PRF is the number of pulses of output per second in US waves. When the irradiation time rate is the same, the PRF is lower, and the longer the pulse per time. [...] Background: Ultrasound...

PRF is normally expressed as the number of pulses transmitted in 1 s and is therefore denoted in Hertz or pps (pulses per second). Typical values for a marine radar are 1000–3000 pps. The …

2023年5月23日 · Regulacja wartości PRF jest jedną z najczęściej używanych opcji optymalizacji obrazu dopplerowskiego. Bo też bez odpowiedniej regulacji częstotliwości powtarzania …
