Use this feature to bias the shape of the TVT curve to avoid crossing false echoes from
fixed objects.
Adjustment to this parameter is best done while viewing the echo profile with Dolphin
Plus. Refer to the Dolphin Plus online help for details. The TVT curve is divided into 40
breakpoints, accessible by enabling the point number as the breakpoint index field. Each
breakpoint is normalized to a value of 0, as displayed in the parameter value field. By
changing the breakpoint value, up or down, the intensity of the bias applied to that
breakpoint of the curve is respectively changed. By changing the value of adjacent
