Pulsed Wave Doppler Features

Doppler measurements and calculations available for all linear, curved, and phased array

transducers
Fast Fourier Transformation (FFT) processing of 32 to 256 points

FFT speed up to 1,920 FFTs per second at the highest sweep speed

Up to four user-selectable transmit frequencies per transducer

Simultaneous 2D-mode and Doppler display and 2D/Doppler with color (Triplex)

User-selectable Doppler update mode

User-adjustable Doppler scale and position controls

Angle correction of 0° to 89° in one degree increments

Transmit frequencies of 2 to 7.5 MHz

Downshift frequency and high-PRF Doppler

Doppler grayscale and colorization (tint) maps

Spectral invert

User-selectable frequency (kHz) or velocity (m/s) display format

Wall filter selections: 20 Hz to 1,600 Hz

Adjustable Doppler Gate size from 0.1 cm up to 4.0 cm, depending on the transducer

Flow angle correction on real-time or frozen images, with velocity readout update

PRF range from 100 Hz to 52,000 Hz

Doppler signal processing that enables automatic calculation of waveform statistics during

real-time imaging
Derived waveform Doppler trace function analyzes frozen Doppler spectrum for mean and

maximum velocity information. Waveform may be set to trace above baseline, below
baseline, or both.
Doppler audio output while in Doppler cursor mode

Doppler CINE control feature — up to 30 seconds of Doppler data can be stored

Five sweep speed selections

Gain of 0 dB to 90 dB in one decibel increments

