M-Mode Display
The M-Mode display shows the direction and intensity of the blood flow velocity for the
corresponding depth range. Red indicates blood flow toward the insonating transducer probe.
Blue indicates blood flow velocity away from the insonating transducer probe. Brighter colors
indicate greater intensity of the signal. The sample depth is displayed as a horizontal line on the
M-Mode graph.
Spectrogram Display
The spectrogram display shows the Doppler spectral waveform of the blood flow velocity at the
sampled depth.
