Power Mode LCD Selections
When Power mode is active, you can access the related LCD selections by
rotating the FUNCTION SELECT control on the LCD panel to highlight the
P tab on the LCD.
LCD Selection Description Settings
|Window
Adjusts the Position or Size of the color ROI.
POS (position) or Size
|2D FOV
Reduces the field of view (FOV) for the 2D image to equal the
width of the color ROI by using the trackball.
Off, FOV, POS
|
PSP/QSP
(Available with the SONOLINE G60 S system; requires the
Cardiac Imaging option for the SONOLINE G50 system)
Selects Parallel Signal Processing or Quad Signal Processing.
The QSP setting is only available for phased array transducers.
Available for the SONOLINE G60 S system only.
Off, PSP
|
Persistence
Causes the signals obtained from blood flow to remain in
the color ROI for longer periods of time when the setting
is increased.
Off, 1, 2, 3, 4, 5, 6,
or 7
|
Color Scale
(Requires software version 1.3 or higher)
Displays color flow in both directions (Full – red and blue),
toward the transducer only (Up – red), or away from the
transducer only (Down – blue).
Full
Up
Down
|
Flow Stage
Allows selection of system settings that are closely
optimized for hemodynamic flow conditions.
H – high velocity and low resistance
HM – medium high velocity
M – medium velocity and high resistance
ML – medium low velocity
L – low velocity and low resistance
H, HM, M, ML, or L
|
Density
Selects the density of acoustic lines passing through the color
ROI. Increasing the line density increases resolution and
decreases frame rate.
1, 2, 3, 4, or 5
|
Range
Selects the dynamic range for Power mode. 10 to 70 in
increments of 5
|
Flash
Selects a level of tissue motion discrimination. 1, 2, 3, 4, or 5
|
Power Map
Selects a color display for Power mode. The energy map
overlays the gray scale image.
1, 2, 3, 4, 5, or 6
|
Dir Power
Select a map to identify direction of flow in relationship to
the transducer.
Off, A, B, C, or D
