OREX Ltd. is a market innovator in the field of portable Computed Radiography Technologies—
designed and priced for low-volume clinic or field unit needs.
Founded in 1995 under the name of Digident, the company initially entered the market of desktop
dental radiography providing high quality, portable CR reading units for dental and orthodontic
professionals around the world. The secret of Digident/OREX’s rapid success lies in the best cost-
performance ratio on the market.
OREX designs, manufactures and markets phosphor image laser scanners. These units replace the
traditional x-ray film and light box. The scanners allow the user to immediately read the x-ray image
from the phosphor plate, and transfer it to a DICOM 3 compatible digital computer file. Once
transferred, users can manipulate the digital image for close-up screening, or transmit it for long-
distance consultation. After each scan, the phosphor plates are automatically erased by the unit, ready
for re-use.
OREX provides clients with a full solution including phosphor image plates, laser readers, software
for image processing, storage, retrieval and communication in Picture Archiving and
Communications System (PACS) compatible format.
The company’s mission is to become a leading provider of compact personal CR systems. Following
the successful penetration of the global dental market, the company changed its name from Digident
to OREX and expanded its markets and product lines to serve the dental, medical, military, industrial
and veterinary fields.
“We are committed to assisting our customers in obtaining maximum value from
OREX products by providing excellent support at exceptional value.”

Safety
Laser Safety Instructions
1. During nominal operation, the scanner is closed
and sealed with a protective cover. That is for
preventing the laser from being exposed to the
outside area, and to prevent access to the laser
by the user.
2. During nominal operation, the cover should not be
removed. Removing the cover shall be done only
for service purposes, and by a qualified technician
for service operations.
3. Any service operation shall be done without
activating the laser unit. Disconnecting the
relevant connector on the laser board will
disconnect the power supply to the laser, and
deactivate the laser unit for service operations.
4. In case the laser must be operated during service
operation, the service technician shall make sure
that the optical unit is located within the cylinder
area, where the laser beam is blocked and cannot
leak outside.
5. When a service operation is taking place, with
cover removed and laser activated, avoid direct
exposure to the laser beam.
