Laser Safety Instructions
• During nominal operation, the scanner is closed and sealed with a protective cover for safety reasons.
• Duringnominaloperation,the covershould not be removed. Removingof the cover shall be doneonly forservice
purposes, and by a qualified technician for service operations.
• Service operations that do not require the laser should 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.
• In case the laser must be operated during service operation, the service 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 procedure in
Disconnecting the Laser on Page 32. If the laser must be activated during the service procedure, wear protective
safety glasses at all times. The required laser safety eyewear must be intended for HeliumNeon/PDT lasers, have

Section 2: System Description
Introduction
Throughout this manual the KODAK Point-of-Care CR 120/140 Systems will be referred to as the
Point-of-Care CR 120/140.
The Point-of-Care CR 120/140 is designed for the reading of phosphor X-ray screens (CR) by medical professionals.
The system consists of the Point-of-Care CR 120/140 unit and the software package that includes:
• The KODAK QC Software that operates the unit.
• An image viewing and archiving software package that supports the DICOM 3.1 standard and was approved by
Carestream Health.
• The system features 8 x 10in., 9.5 x 9.5 in., 10 x 12 in., 11 x 14 in., 14 x 14 in., 14 x 17 in.,15 x 30 in., 14 x 33 in.,
24 x 30 cm digital image reading and viewing archive.
Operational Principles
The Point-of-Care CR 120/140 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 120/140 enables the user to read a screen quickly, and then erase it to be ready for the next
scan. The unit is compact and easy to use.
Using the Point-of-Care CR 120/140 enables medical professionals to “go digital” without changing their work
practices or X-ray equipment.

Component Names and Descriptions
Part Name Description
USB Board The USB board receives operational commands from the host PC workstation via the
USB port, and sends the commands to the appropriate scanner component. It also
transmits image data from the scanner to the PC.
Motion Board The motion board controls the loader and roller motors and erase lamps. It reads the
scanner sensors and passes the information to the USB board.
Linear Slide Assembly The linear slide assembly moves the photo multiplier (PM) and the optical head
assemblies back and forth within the drum.
Optical Head Assembly The optical head assembly includes the laser module and the rotational motor that
rotates the laser tube and a mirror during scanning. The laser module’s beam
illuminates the phosphor screen and the mirror collects the light reflected from the
phosphor screen and directs it to the photo multiplier.
Photo Multiplier (PM)
Tube The photo multiplier (PM) tube collects the photons emitted from the screen.
Key Assembly and Tray
Assembly These complementary assemblies guide the cassette into the scanner and secure it in position for the duration of the scanning process. The auto-loop mechanism, which is
attached to the key assembly, controls the distance that the screen is returned into the
cassette at the end of the process.
Power Supply The AC/DC power supply provides DC power to the scanner components.
Loader Stepper Motor
Assembly The loader stepper motor assembly extracts the phosphor screen from the cassette in preparation for insertion into the drum and assists in inserting the screen into the
cassette.
Roller Motor Assembly The roller motor assembly pulls the phosphor screen from the cassette into the drum.
Erase Lamps Assembly The erase lamps assembly brightly illuminates the phosphor screen after scanning, to
erase the image so that the screen is ready to be used again.
Erase Lamps Inverters
Assembly The erase lamps inverter assembly converts the 15 VDC input to high voltage output to power the erase lamps.
Sensor Board The sensor board is a through board used to connect the sensors to the motion board.
Sensors
Eraser Lamps Sensor The erase lamp sensor detects an erase lamp failure.
Left and Right Limit
Sensors The left and right limit sensors indicate the end of travel of the linear assembly movement.
Roller Sensor Detects when the screen enters and exits the rollers.
W0 Sensors Top and
Bottom The W0 sensor determines the activation and deactivation of the rollers according to screen presence at the entrance to the drum.
Z0 Sensor The Z0 sensor detects the presence of the screen in the drum.
Screen Size Sensors Four screen size sensors determine the size of the CR screen by the location of the
screen guide that is positioned by the screen as it is inserted into the drum.
15 x 30 Presence
Sensor Installed in the key assembly, this sensor detects the presence of a 15 x 30 in. cassette adapter.
