Overheating

Do not block the air circulation around the scanner. Always maintain at least 6 inches (15 cm) clearance ar ound the
scanner to prevent overheating and damage to the system.

Laser Safety Instructions

• During nominal operation, the unit is closed and sealed with a protective cover for safety reasons.

• During nominal operation, the cover should not be removed. Removing of the cover shall be done only for service
purposes, and by a qualified technician for service operations.

• Service operations that do not require the laser should b e done without activa ting the la ser un it. Switchin g OFF
the DIP switch on the laser board will disconnect the power supply to the laser, and deactivate the laser unit for
service operations.

• In case the laser must be operated during service operation, the ser vice technician shall make sure that the
optical unit is located within the scanner drum, where the laser beam is blocked.

Laser Warning

When a service operation is taking place with the cover removed, disconnect the laser according to the procedur e in

System Description

Section 2: System Description

Introduction

Throughout this manual the KODAK Point-of-Care CR 360 System will be referred to as the Point-of-Care CR 360.
The Point-of-Care CR 360 is designed for the reading of phosphor X-ray screens (CR) by medical professionals.
The system consists of the Point-of-Care CR 360 scanner and the software package that includes:

• The KODAK QC Software that operates the scanner.

• An image viewing and archiving software package t hat supports t he DICOM 3.1 st andard and was approved b y
Carestream Health.

• The system features 8 x 10 in., 10 x 12 in., 14 x 17 in., 9.5 x 9.5 in., 11 x 14 in., 14 x 14 in., 14 x 33 cm, 24 x 30 cm,
and 15 x 30 cm digital image reading and viewing archive.

Note

Throughout this manual Front of the unit ref ers to the side where the cassettes are inserted. Right and Left are as
viewed when facing the front of the unit.

Operational Principles

The Point-of-Care CR 360 is a digital imaging system for image acquisition and processing of static projection
radiography that uses a phosphor screen 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
screen. The luminescence signal is digitized. The data is then subjected to digital image processing.

The Point-of-Care CR 360 enables the user t o read a screen quickly, and then erase it to be ready fo r the next scan.
The scanner is compact and easy to use.

Using the Point-of-Care CR 360 enables medical professionals to “go digital” without changing their work practices
or X-ray equipment.

System Overview

Component Names and Descriptions

Part Name Description

Controller Board The controller board is the main board on the scanner. The controller board

connects the scanner to the host PC workstation via the USB port. The
controller board runs the firmware, and receives operational commands from
the host PC workstation via the USB cable, and transforms the commands to
the appropriate scanner hardware commands. The controller board generates
the +/- 15 Vac to the DPMT and the +/- 12 Vac to the IMCS. It builds the
scanned images and sends them via the same USB cable to the PC
workstation. The controller board serves as the link between all peripherals in
the scanner (i.e., Erase lamp, IMCS, Laser Board, and DPMT)
