Image Display
Video Standards:
EIA/NTSC and CCIR/PAL
Monitor:
Color 38 cm (15"), non-interlaced, MultiSync (SVGA)
Gray Scale:
256 levels
Color:
Up to 16.7 million colors
Image polarity:
Positive (black on white) or negative (white on black)
Date/Time display:
System displays current date and time above the imaging
area. Clock freezes in frozen image.
Daylight saving time changes available in system presets.
Image field size:
3.5 MHz = 20 to 240 mm
(by frequency)
5.0 MHz = 20 to 240 mm
7.5 MHz = 20 to 140 mm
10.0 MHz = 20 to 240 mm
12.0 MHz = 20 to 240 mm
The depth is selectable in increments of 10 mm. Minimum
and maximum depth values for each frequency are
transducer dependent.
Image Orientation:
Left-to-right or right-to-left orientation for 2D, Split (B+B),
Dual, and 4B modes; 2D image in mixed 2D/M-mode and
Doppler. Active image indicator designates direction of
scan. 90-degree rotation for 2D, Split (B+B), Dual, and 4B
modes; 2D image in 2D/D-mode and 2D/M-mode.
Image Position:
Image can be offset vertically and horizontally

Overall System Receiver Gain combined with DGC Gain
totals 60 dB
Independent Receiver Gain for 2D/M-mode, Color, Power,
and Doppler
Depth Gain Compensation (DGC) – Eight DGC slide
controls for DGC Gain
Pre-processing – Edge Enhancement in four steps; Image
Persistence in six steps; Dynamic Range 35 to 70 dB in
1-dB steps.
Post-processing – Variable grayscale compression maps:
L, B, G, C, S, D, A, E,
Focusing – 1, 2, and 4 transmit focal zones for all
electronic array transducers; number and position of focal
zones are user-selectable
