High definition data and video projectors for the presentation of radiology pictures in meetings and for teaching purposes.These projectors have a system that allows the representation in DICOM 14 mode. Some projectors are supplied with a simulated DICOM mode, whereas the Canon XEED projector series allows the calibration of the DICOM standard to be performed on site and so achieves a 100% DICOM conformity. With the help of the Acuscreen Pro calibration system the conformity can be regularly checked and if necessary recalibrated.
