LOGIQ™ P6/P6 P
Adjusts the baseline to accommodate faster or slower blood
flows to eliminate aliasing.
Velocity scale determines pulse repetition frequency. If the
sample volume gate range exceeds single gate PRF capability,
the system automatically switches to high PRF mode. Multiple
gates appear, and HPRF is indicated on the display.
Estimates the flow velocity in a direction at an angle to the
Doppler vector by computing the angle between the Doppler
vector and the flow to be measured
Threshold assigns the gray scale level at which color
information stops.
Allows a specific color map to be selected. After a selection has
been made, the color bar displays the resultant map.
Allows blood flow to be viewed from a different perspective, i.e.
red away (negative velocities) and blue toward (positive
velocities). The real-time or frozen image can be inverted.
Controls the number of samples gathered for a single color flow
vector.
Quickly adjusts the angle by 60 degrees
Display layout can be preset to have B-Mode and Time-motion
side-by-side or over-under.
In the side-by-side layout, there are three display alternatives
defined: equal priority, time-motion priority or time-motion with
B-Mode reference.
In the over-under layout, there are three display alternatives
defined: time-motion priority, B Mode priority or equal priority.
Sizes the sample volume gate
Slants the B-Mode or Color Flow linear image left or right to get
more information without moving the probe
