Error if present will be solved with a check of the installed software version, see step 2. The Software Version loaded onto the digitizer and that one installed on PC do not match.
Please perform the upload via Service Client. Only displayed if software on PC and digitizer do not match. The steps outlined here are only to confirm that the NX workstation was prepared by production for the CR X system.
See also important note below. Checking Software Version NOTE The digitizer only boots-up completely if the software version on the digitizer and the software version on the control PC for download to the digitizer match.
As digitizer and control PC are not staged together, it is possible, that the digitizer or the control PC has a different digitizer software version installed. In this case error appears with each re-boot of the control PC. For installation instructions refer to section 3. No further action required.
Exception: If newer digitizer software is available on MEDNET in the freeware area perform digitizer software update or upgrade according to the installation instruction which is part of the software. Completion of Installation The purpose of this section is to show the tasks that are required to prepare the digitizer for hand-over to the clinical application specialist. The following table lists these tasks. Do not take an image plate of one tray and put it in another tray.
Use only a dry cloth or blow away possible dust with compressed air to clean the tray. When ordering, the actual revision of the spare part is delivered.
Open the shutter. Turn the cassette around, so that the black tube side is above. Let the black tray and image plate slide out carefully onto the table. Put the black tray with the image plate onto the cassette.
The tray has 2 little hooks. Put the tray onto the cassette in such a way that the hooks reach over the border of the cassette. This to avoid a bending of the tray.
Check the image plate for scratches. Clean the image plate and the tray as follows:. Moisten the cloth with cleaner and wipe the image plate surface softly and evenly phosphorous side and rear side.
Leave the image plate surface to dry for about 10 minutes to allow the solvents to evaporate. Use only a dry cloth or blow away possible dust with canned air to clean the tray thoroughly. Once the image plate surface is dry after about 10 minutes , check once again for particles of material and other impurities.. Put the tray with the image plate back into the cassette. Technical Image Quality Check of the System During the Technical Image Quality Check of the system a flatfield image is exposed and compared at the lightbox with a test pattern lowest acceptable quality.
This procedure is divided in 3 steps:. Compare the scanned flatfield with the imported limit pattern lowest acceptable quality. Creating the Flatfield Test Image 1 Select the largest available cassette. If possible, use a 35x43 cm Genrad cassette. NOTE: Select the following exposure parameters using a 1. The values are approximate and may vary among the X-ray devices. Turn the cassette by Expose again with 10 Gy.
Insert the exposed cassette in the digitizer. Any other examination type may give a result which cannot be compared with the limit pattern. Checking the Images at the Lightbox 1 At the lightbox or the viewing station visually compare the scanned flatfield with the limit pattern. The limit pattern represents the lowest acceptable image quality in slow scan and fast scan direction.
If the scanned image visually looks as good or better than the limit pattern, the image quality is okay. If there are unacceptable effects in slow scan or fast scan direction see chapter 3.
NOTE: The slow scan direction is always the long side of the image plate. These darker zones also have to be used for image quality evaluation in slow scan and fast scan direction.
See next page. Flatfield with Genrad Cassette. It shows the most important steps of the last scan cycle. Saving the HOT file documents the successful completion of the technical installation of the digitizer as well as the successful connection to the control PC.
Hand-over of the System to the Clinical Application Specialist 1 Inform the clinical application specialist about completion of technical installation. System Overview CRX in a Nutshell NX Workstation in a Nutshell Image Plates with IPs in a Nutshell Digitizer Boot-Up Functions of Calibration Board Signal Corrections before and during Scan Stall Detection Explanation of one scan cycle: 1 The user inserts the cassette with image plate IP into the digitizer 2 The chip reader reads the image plate data 3 The user enters the patient data at the the NX workstation and selects the ID button to send the data to the digitizer 4 The cassette unit opens the cassette and pulls out the tray with IP 5 The transport unit drives the image plate to the slow scan unit 6 Via calibration board the digitizer determines the position of the polygon mirror to synchronize scanning and digitizing.
The processed images are stored on the internal hard disk of the NX Workstation. However, the NX Workstation can only provide a limited amount of storage capacity. The final archiving must be realized either by printed hardcopies or a PACS.
Moreover, the NX Workstation decodes the routing data and sends the image data to the selected destinations e. Printer, PACS. For the NX Workstation a lot of licensed software options e. The tray is used as carrier to pull out the image plate and put it back into the cassette. The tray only leaves the cassette for approx. Figure 4 Workflow of an examination with the CRX system in the view of a radiologic technologist: Step Go to processing station. This takes approx. The digitizer sends the image data during scanning i.
It checks e. Follow-up period approx. To correct irregularities in the optical path, the digitizer measures at each boot-up the timings of the laser beam between pin diode 1 and 2, 2 and 3 and so on. As a result a kind of "calibration curve" is created, which influences the frequency of AD conversion.
This corrects possible distortions. To correct irregularities in the polygon run, the digitizer measures the timings between the BOL and EOL signal during each scan. Certain irregularities, which may be caused by external vibrations or the polygon ball bearings are smoothed by calculating mean values of several scan lines. When an IP is inserted the polygon starts up. The length of the AD window and "Laser On" depends on the image plate size.
The exact dose is measured by production people and entered in the system. By combining the measured values of several lines the sensitivity is automatically adjusted HT at PMT Shading correction: The digital value of each pixel is corrected with a correction factor determined during shading calibration. How does it work in general: When the stepper motor is accelerating the stall detection is switched off, as torque differs to much during acceleration.
When the motor reaches a stable speed, e. When the torque increases and reaches a certain "switch off torque", as the motor reaches the end position, the motor controller detects the stall position and drives the motor a certain number of steps e. During decelration time the stall detection is switched off, as torque differs to much during deceleration. Rubber pieces in the end position support that the motor can be driven with relatively high speed towards the end position.
If the torque increases to the "switch-off" torque before the motor is supposed to reach the stall position, the motor is also stopped. The software however "knows" that this stop comes too early and issues an error message e.
NOTE: The motor curves shown above are simplified. In reality the motor speed can be reduced just before the stall position, or can even be reduced in several steps before it stops. Supports when a system is planned to be upgraded. The required system components can be analyzed and identified based on the chart. The CR X System version contains a continuous number which is increased when one of the delivered system components changes.

Drawer Unit Adjustment Preparing the Drawer Unit Adjustment Checking and Adjusting the lateral Position Checking and Adjusting the Height Checking the Switch Position Adjusting the Switch Position Cassette Edge Sensor Position Adjustment Laser Beam Position Check and Adjustment Performing the Laser Beam Position Check Performing the Laser Beam Position Adjustment Shading Calibration Verifying a successful Shading Calibration Possible Reasons for a failed Shading Calibration Stall Calibration Overview of Adjustments and Calibrations The following tables give an overview of adjustments and calibrations for the digitizer.
In case of sporadic or persistent errors or to identify the possible root cause of an incorrect laser beam position. To solve errors or , if an incorrect laser beam position is the root cause. Whenever the PMT or light collector have been removed e. Whenever stripes in slow scan position are visible, which cannot be removed by cleaning of the scan line with the cleaning brush.
After replacement of a motor or mechanical assembly where a motor with stall detection is built in After replacement of the IP handling board as this has the motor controllers built in During preventive maintenance.
Adjustment of the optimum height and lateral position of the upper drawer unit plate for reliable image plate transport in and out of the cassette. Difference: Drawer adjustment tool version 2 has an additional gauge integrated to check the maximum height position marked with text "max.
The drawer adjustment tool is part of delivery of following spare parts:. This document describes the adjustment with drawer adjustment tool version 2. Where applicable, differences to version 1 are described. Simultaneously press the two buttons A positioned underneath the feed table. When pushing the drawer unit only do this via drawer unit axle. Check, whether plastic finger at drawer unit is aligned with the lateral stop of the drawer adjustment tool.
In case the lateral stop is aligned with the plastic finger at the drawer unit there is no adjustment required. Continue with section 2. Otherwise perform lateral adjustment as described in next steps. The plate marked with "min. The plate marked with "max. NOTE: With drawer adjustment tool version 1 it is possible to check the minimum height only. It is not possible to check the maximum height.
In case the height is OK on both sides there is no height adjustment required. Otherwise proceed with next steps. Press down the drawer unit upper plate after each adjustment cycle before checking the height again. Again, check the height adjustment min. Wait till the green light at the user interface lights up takes approximately 1 minute. Miss-alignment can lead to IP jams, laser reflections or cracks in the light collector. If the distance is OK, continue with step 9 , otherwise continue with next step.
See Figure The PMI board carrier is adjusted this way, that the light collector is mounted stress free. Check: With closed cassette unit the switch may not interrupt the power: The status indicator LED lights up.
Figure Check: With cassette unit opened approximately 1 cm, the switch must switch off the digitizer. If it does not switch off, continue with section 2. Shift the switch to the front switch does not close with inserted cassette unit or to the rear switch switches too late when cassette unit is opened.
Cassette Edge Sensor Position Adjustment Adjustment of the switch position, so that it reliably detects whether the cassette is inserted the right way. After replacement of the cassette edge sensor. Insert a cassette the right way, i. If the sensor does not switch, open the fixation screws at the cassette edge sensor and push it more to the left. Fasten the fixation screws and repeat step 2. Insert a cassette the wrong way, i.
When using a multimeter, the resistance should be outside the measuring range. If the sensor switches, open the fixation screws at the cassette edge sensor and push it more to the right. Repeat step 5. If the sensor does not switch, repeat the complete procedure once more, to confirm the proper adjustment. Adjustment of the optic module this way that the laser beam position is centered to the calibration board.
In case of sporadic or persistent errors or to identify the possible root cause of an incorrect laser beam position To solve errors or , if an incorrect laser beam position is the root cause. By putting the switch on the distributor board to ON position the laser beam position check functionality is activated: The yellow "LED 1" lights up.
Do not touch the input side of the power supply by hand or with any tool. Check that the yellow LED on the distribution board is ON: This is the proof, that the check functionality is activated. Eye injuries possible. Do not keep any tool in the laser beam while the laser is switched on. The Polygon motor is audible.
NOTE: The laser beam switches off automatically after 30 minutes. Check, whether laser beam is really switched on: Look from the digitizer right hand side, whether the red laser line is visible. If laser beam is visible, the laser beam position adjustment is required.
Set the switch on the distributor board to the OFF position before handing the digitizer over to the customer. The Laser Beam Position Check is performed.
See steps 1 to 17 in section 2. Open the four screws at the optic module position plates secured with red lacquer. If the laser beam position adjustment has been performed: Verification is done with the shading calibration procedure. Determine the sensitivity of the scanning system for each pixel of the scan line: A flatfield is scanned. Perform a shading calibration in following cases:. Select the largest available cassette. Open the cassette and check the image plate IP for scratches.
If no scratches are visible, select this IP. Ensure that the entire image plate is fully exposed! The collimated field must be larger than the image plate. After the second exposure the cassette has been exposed in total with a dose of approximately 20 Gy.
In case of an error refer to section 3. To keep a certain calibration file, save it with a different name. If the scanned image does not show stripes in fast scan or slow scan direction or large area inhomogeneities no further action is required. In such a case please contact your local Agfa representative. Checking the images may only happen on light boxes and viewing stations that comply with the specified installation and configuration conditions for diagnostic reading.
For details please refer to the respective instructions of the viewing stations or light boxes. Possible Reasons for a failed Shading Calibration There are mainly following reasons for a failed shading calibration:. Reason for different proceeding: In opposite to Genrad General Radiology cassettes, FLFS cassettes do not have the complete IP area covered with a backscatter protection: The lead foil does not cover approximately 10 mm on the upper and lower side of the cassette.
NOTE: This covers the area where the cassette has no backscatter protection. Only this area has to be covered, which is used by the digitizer to determine the shading calibration curves. FLFS cassette. Put a cassette underneath this area. This prevents, that the missing backscatter protection falsifies the shading calibration result.
These darker zones also have to be used for image quality evaluation in slow scan and fast scan direction to verify a successful shading calibration. The stall calibration determines the optimum motor current for stall detection: The motor drives several times to its home and end position with different motor currents. The mean value of these different motor currents is used as motor control current, where the steps of the motor are in the specified, allowed range.
It compensates the differences e. After replacement of a motor or mechanical assembly where a motor with stall detection is built in. NOTE: The stall calibration does not harm - it can be performed anytime.
It is required however only in the cases as described previous page. The digitizer CRX does not have device specific settings which may be altered by the service engineer.
All settings are either determined in production and stored in E-Lables in the corresponding module, or - at replacement of parts - have to be determined again by an adjustment routine. These new values are automatically written to the corresponding E-Label.
