Persistence
MR-Flow
Description
Retains the largest pixel color value until a
larger value is detected or preset time has
elapsed.
When a higher color value for a pixel is
detected, that value is retained and the
persistence time is reset for that pixel.
When the persistence time elapses for that
pixel, color is deleted and it returns to gray
scale.
Changes the number of focal zones in the
CFM area to 3. A graphic caret
corresponding to the focal zone position(s)
appears on the right edge of the image.

turned on or off from the Color Flow Menu.
Available only for LA39, C551 (CAE),
