2D-Mode Parameter Selections
Selection
Description
Trapezoid
Trapezoid/Linear
Enables linear or trapezoid image format for linear transducers.
On displays a trapezoid image.
Off displays a linear image.
Note: For systems without a touch screen, the selection is assigned to a soft key.
Space Time
Adjusts the balance between the image line density (resolution) and the frame rate.
0 to 3
Note: For systems without a touch screen, the selection is on the LED panel.
Maps
Selects a processing curve that assigns echo amplitudes to gray levels.
A, B, C, D, E, F
Note: For systems without a touch screen, the selection is on the LED panel.
Tint
Changes the color of the image by adding blue, red, yellow, or green to the gray in a gray map.
Available settings: transducer-dependent
Note: For systems without a touch screen, the selection is on the LED panel.
Edge
Edge Enhancement
Distinguishes the contours of a structure during imaging.
0 (none)
1 to 4
Note: For systems without a touch screen, the selection is on the LED panel.
Persist
Persistence
Creates a visible smoothing effect by maintaining lines of image data for each frame of
imaging. A higher setting includes more frames in the image data.
Available settings depend on the transducer and exam type
THI
Tissue Harmonic Imaging
Enables or disables the Tissue Harmonic Imaging feature, used to enhance contrast
resolution.
Note: For systems without a touch screen, the selection is assigned to a soft key.
