6.3 Overview of Barco’s DICOM THEATRE®

Architecture

Atypical example of a medical visualization system is BARCO’s DICOM compliant DICOM THEATRE ®.
Thissystem provides consistent images for consulting, reviewing and training applications.
Inthis system the MGP projector is used as the large screen display device controlled and tuned by the M ediCal®Pro management
software providing optimal image quality and consistency at any time.

Analogy to the typical architecture

Displayfunction : thefunction can be chosen to be DICOM, DIN, standard or custom. Thisis done in the projector.
Preset: is determined by the user on MediCal®Pro and corresponds to a particular display function and color temperature.
Controla nd calibration unit: Role played by MediCal®Pro .
Displayunits: one or more flat panel displays and one or more projectors

Display function, page 69
Color temperature, page 67
6 predetermined presets, containing each of them one particular display function and one particular color temperature, are stored
inthe projector, they can however be overwritten at any time by MediCal®Pro. Thepresets have been pre-calibrated by Barco and
donot take account of any amount of ambient light, and could hence be referred to as DICOMcompliant in dark room conditions at
timeof manufacturing. It is advised to re-calibrate these presets to match them to the actual environment.
The factory settings can be restored via the projector’s menu.
Eachtime a preset is adapted, a calibration has to be done in order to verify conformance and consistency.
