Factory Characterization of Dome Displays
Automatic DICOM Calibration
Dome developed the industry's
first internal automatic calibration
system, and continues to lead
with intervention-free DICOM
conformance. Every Dome CX and
EX display is precision-characterized
at the factory, storing critical LCD
parameters in the display's internal
memory. This data, in conjunction
with the display's integrated
RightLight™ photometer monitor-
ing backlight luminance, is used by
Dome's CXtra™ software to auto-
matically and continuously per-
form DICOM correction as needed
– ensuring continuous DICOM
conformance. The end result:
Dome displays come DICOM
calibrated right out of the box –
and stay calibrated for life.
Display innovation.
1024 Calibrated Shades of Gray
Display resolution is limited by
two main factors: first, the ability
of the operating system and
software to deliver more than
256 shades of gray per pixel, and
second, the hardware limitations
of the LCD display itself. Dome's
DA
4
interface board technology is
designed to overcome these limi-
tations and display a full 1024 cal-
ibrated gray shades on the panel.
Critical LCD panel
parameters are measured
from the center of the
screen, as per AAPM TG18
and DIN standards.
RightLight™ monitors
the active area at the
center of the display, an
area up to 30 times larger
than front-edge sensors.
The result: Outstanding
DICOM accuracy.
As illustrated on the diagram, this
provides clinicians with 4x the
current resolution of gray shades
displayed via traditional image
processing techniques within a
Windows XP environment. The
upcoming release of the Vista
operating system will allow imag-
ing software to take full advan-
tage of the Dome DA
4
architec-
ture and display the 1024 cali-
brated gray shades."
High-Bright Technology
Dome EX color displays feature
high-bright technology,
providing high-brightness,
high-contrast images – ideal
for both diagnostic grayscale
and color medical image
viewing. Significantly brighter
than standard color displays,
Dome EX color displays provide
quality DICOM grayscale and
color viewing in any lighting
condition.
