Direction 5446729-100 English Rev. 7
Configurable
Parameters
• Scale: Imaging of higher velocity flow requires increased scale values to avoid
aliasing.
• Threshold: Limit color flow overlay to low level echoes inside vessel walls. Help to
minimize color ‘bleeding’ outside vessel walls.
• Sample Vol: Place the sample volume gate to sample blood flow.
• Steer: Provide a doppler cursor angle suitable for linear probe orientation.
• Wall Filter: Decrease, unnecessary low frequency signals caused by motion.
• Color Map: Show the direction of the flow and highlight the higher velocity flows.
• Invert: Allow to view blood flow according to personal preference, without flipping
the probe.
