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.”

1. PcCR 1417 System Introduction
1.1 Overview
The OREX PcCR 1417 System is used by medical personnel for reading phosphor
x-ray plates (CR).
The system is composed of two main parts:
• The OREX PcCR 1417 scanner (see Figure 1-1).
• The PcCR 1417 software package, that includes:
• The OREX Scanner
Interface software that
operates the scanner.
• An image viewing and
archiving software package
that supports the DICOM 3.1
standard and was approved
by OREX, such as HIPAX.
The following depicts the PcCR 1417 System operational principles, mechanical
description, technical information, features, and instructions on how to handle and
clean plates.
1.2 PcCR 1417 Operational Principles
The PcCR 1417 is a machine used for digital image acquisition and processing of
static projection radiography. The PcCR 1417 uses a phosphor plate with energy
storage capability as an x-ray image receptor.
After exposure, a laser beam, which stimulates luminescence proportional to the
local x-ray exposure, reads the plate. The luminescence signal is digitized. The
data is then subjected to digital image processing.
The OREX PcCR 1417 reader enables the user to read a plate quickly, and erase it
to be ready for the next read. The reader is compact and easy to use.
The main advantage of the PcCR 1417 system is that it enables radiologists to “go
digital” without changing their work practices or x-ray equipment.

2.3 Using the Image Plate with Cassette
An image plate comes in a cassette, and should remain there. The only time a plate
is out of the cassette is when the scanner automatically loads the plate for reading.
It is important to keep the image plate positioned correctly throughout any
procedure.
7

To load a cassette into the reader:
1. Verify that the scanner is On, and that the System LED is
green, indicating that the scanner is ready.
2. Insert the cassette into the scanner:
• The face (white) side faces up,
• The open edge points toward the scanner, and
• The cassette is centered exactly from side to side in the scanner slot.
The cassette locks when it reaches its proper position in the scanner. Once the
cassette locks, the image plate loads automatically.
Ordinarily, the cassette unlocks automatically after scanning, ready for re-use. In
case you need to unlock the cassette manually, pull the screw beneath the slot to
unlock the cassette.
