Calibration
Each display is calibrated in the factory before it is sent to the customer.
After this calibration, black and white luminance are set to the ideal
level.
A stabilization routine, constantly active when the display is on, keeps
these levels constant using the built-in sensor.
Display Controller head
A display controller (graphics board) converts the digital data from the
computer into digital or analog video voltages.
Most of the common display controllers contain just one set of video
and sync outputs. However, some high-end boards, like some of the
BarcoMed boards, contain two sets of video and sync outputs. This is
called a dual head display controller. It is like two complete display
controllers implemented on one single unit.
A dual head board in the computer behaves exactly as if two separate
boards were installed.
DICOM
DICOM stands for Digital Imaging and Communications in Medicine. It is
a standard developed by the American College of Radiology (ACR) and
the National Electrical Manufacturers Association (NEMA).
The standard specifies how digital image data can be moved from
system to system.
In addition, Supplement 28 Part 14 specifies a function that relates pixel
values to displayed Luminance levels and is called Grayscale Standard
Display Function.
