Introduction The Radlink CR-Pro is a radiological device, which digitizes erasable phosphor plates and transmits the image to an onboard computer for review, archiving or forwarding to other facilities for further evaluation and archiving. The CR Pro only utilizes cassettes manufactured by Radlink. The CR Pro’s unique design makes it virtually maintenance free, as there are no mirrors or galvanometers, which are subject to frequent adjustment.
Chapter 1 Hardware Installation 8
Hardware Installation 1. Place the CR-Pro on a solid flat, leveled surface. 2. Plug the power cord to the AC Power Adapter located on the back of the CR-Pro. (Figure 1) 3. Plug the end of the power cord to an available power outlet. A UPS/Line conditioner is recommended. It is desirable to have the CR-Pro on an isolated circuit to avoid conducted noise from other devices affecting the quality of operation. 4. Plug one end of the Ethernet cable (Cat5/6) into the CR-Pro Ethernet port (see Figure 1).
Chapter 2 Setup Guide and Configuration 10
STEP 1: Application Start Up 1. To start the application double click the Radlink Icon located on your desktop.
2. Image Pro software home screen will appear as Figure 2.
3. Verify that Scanner Status is lit green with READY.
STEP 2: Calibration Procedure Calibration of the CR PRO is required to compensate for any hardware differences and should be performed at least once a month, depending on usage. Recommended: A 14x17 inch cassette must be used for calibration. If a smaller size cassette is used, banding will be apparent at the both sides of scanned images when a larger cassette is used. Remove any grid that might be present. 1.
4. Start Calibration From the application Click Manage CR Setup Calibrate. (Figure 5) The calibration process should take 3-4 minutes to complete. Figure 5 5. Calibration - The CR Pro will scan the exposed plate in order to calibrate the intensity to allow for the best possible images to be acquired from the plate. Once scanned, the system will then go through a second pass and erase the plate to normal levels. The calibration process will take approximately 4 minutes.

Chapter 4 Troubleshooting Guide 24
General Troubleshooting Problem Action No power to the CR Pro Ensure the monitor power is on. Check that the Power Switch on the back of the CR Pro is “ON” and unit is plugged into the surge protector or wall receptacle. If problem persists contact your authorized service provider. Cassette Jam From the Acquisition Software Select “Manage” “CR Setup” “Reset Plate”. If not resolved power off the CR Pro and power back on. If problem persists please contact your authorized service provider.
Cassette Related Problems Troubleshooting Symptom Damage to outer enclosure Possible Causes • Rough handling by technicians • Patient contact during x-ray exposure • • • Plate is not retained in • Bent or damaged the outer enclosure when Snap-Lock clip cassette is out of the unit, or the plate is not extracted from or returned to the cassette. Problem is localized to one cassette.
Chapter 5 Maintenance Procedures 27
CR ProTM Phosphor Plate Cassette Maintenance Procedure The Phosphor Plate Imaging Cassette is a key component in the CR ProTM Computed Radiography System. The CR Pro’s cassette is comprised of the outer enclosure and the phosphor plate. The outer enclosure provides protection to the phosphor plate to prevent physical damage and contamination. It also prevents ambient light from reaching the phosphor plate.
Care and Cleaning To ensure optimum performance from the cassettes and to eliminate potential image artifacts, it is recommended that the cassettes be cleaned and inspected once a month. It may be necessary to clean the cassettes more frequently if the unit is used frequently or if it is installed in an unusually dusty environment such as a veterinary clinic. The following procedure should be followed to clean and inspect the cassette: 1. Inspect the outside of the cassette for physical damage.
4. Twist the screwdriver to extract the phosphor plate (see photo #2). To prevent damaging the phosphor plate, do not apply pressure to the center of the cassette while removing the plate. Photo 2 Caution: In the next few steps, use caution when handling the exposed plate. Handle the plate by the edges to prevent getting finger prints on the surface of the phosphor plate. 5.
7. Wipe the long edges of the plate to remove any accumulated residue (see photo #3). Cleaning the edges of the plate will reduce the possibility of dragging contamination from the edges of the plate onto the phosphor surface when it is cleaned. 8. Dispose the dirty cleaning cloth after use. Photo 3 9. Dampen a new lint-free cloth with either denatured or industrial grade isopropyl alcohol.
10. Wipe the surface of the phosphor plate in the long direction with overlapping stokes. Rotate the cleaning cloth to use a clean section as you progress across the plate (see photo #4). NOTE: do not use a circular motion when cleaning the plate as this may drag contamination from the un-cleaned area of the plate back on to the surfaces that have just been cleaned. Wipe in this direction Photo 4 11. Inspect the phosphor plate for any remaining foreign material; repeat the cleaning process as necessary.
15. Turn the cassette over and clean the lower corners where the side and bottom edges of the cassette join together (see photo #5). Clean Here Photo 5 16. This completes the cleaning and inspection procedure, the cassette can now be returned to service.

USER QUALITY ASSURANCE & MAINTENANCE PROGRAM FOR THE CR-PRO INTRODUCTION: Understanding the basic fundamentals and automating the decisions involved in obtaining good results of x-ray imaging is the foundation of the approach Radlink has taken in the development of the CR Pro. GENERAL: The x-ray tube is essentially a point source of a cone-shaped beam of x-rays.
Chart to define the variables for each X-Ray. Or, better yet, if the site’s Techniques Chart is known by Radlink prior to shipment, a customized Techniques Chart can be loaded prior to the unit’s installation at the site. The XRT can then use the installed Techniques Chart or expand it as required. This user-friendly approach simplifies the XRay set up and provides for flexibility to tailor the image results.
