Retaking and rejecting imagesWhen an image is retaken multiple times in succession, all images that are retaken will be rejected, so only the last image can be output (valid image). The example below shows the flow of operation when an image is retaken twice.

Flow of operation when an image is retaken twice

An invalid image can be changed to a valid image from the preview image screen. However, because only one image can be chosen as valid, the image that was previously valid will automatically be invalidated when another image is validated. In the example below, the lower image shows a case in which the second image taken in the above figure is changed to the valid image.

Changing the valid image

When you touch [Reject] for a rejected image on the preview image screen and make that image the valid image, a window will open and the confirmation message “The No. n image [Exposure Mode] will be rejected. (“n” is the exposure number of the valid image.)” will be displayed. Touch [OK].Also, you can invalidate all the valid images from the preview image screen.

When image processing parameters have been changed before retaking theimageWhen parameters are changed on the QA screen after exposure and then [RETAKE] is touched to retake an image, the parameters used are as follows.• Changes made to the print setting, mark (except “ROTATE” and “FLIP”), and

“Marker” parameters are valid.• For other parameters, those that applied when the first image was taken will be

REXWhen REX is adjusted, the LUT graph shifts in the pixel value direction (right figure).

An enlarged graph is shown below.

This graph depicts an REX for a chest front exposure.The name of the quadrants, from the upper right in counterclockwise direction, are as follows: the first quadrant, the second quadrant, the third quadrant and the fourth quadrant. The first quadrant is the gray scale curve showing the relationship between pixel and density. The third quadrant is the sensor characteristics curve, showing the relationship between the X-ray dose that has reached the sensor and the sensor output value. The fourth quadrant is the logarithm conversion curve, which converts the sensor output value (proportional to the X-ray dose) into a pixel value proportional to the logarithm of X-ray dose. Only the right half of the graph (the first and the fourth quadrants) will be explained here to simplify the explanation.

First, an explanation of the algorithm that determines the gray scale curveThe CXDI selects the maximum pixel value of the upper lung area as the analysis value for chest PA exposure. In the above graph, the analysis value is 1220. Suppose 1.9 D has been specified as the density at the analysis value position. The gray scale curve shifts in the horizontal direction. The amount by which it shifts is determined by the position where the arrow from the analysis value intersects with the arrow from the density.

Next, an explanation of the algorithm that determines the REX.The REX is determined by using the gray scale curve. The position where the arrow from the gray scale curve at reference density 0.75 D (fixed) intersects with the logarithm conversion curve is the REX. Thus, the sensor output value corresponding to the area expressed as density 0.75 D is the REX.0.75 D is the density when the printer LUT is linear, the maximum density is 3.2 D, and the minimum density is 0.2 D.

7.5 EDGE ENHANCE.

NOTE: When parameters are set to excessively high values, artifacts may be generated or effective image information may be degraded.If you think the image looks as if it has been over-processed, set the parameters to lower values, or void the process.

The edge enhancement process emphasizes the edges of the image and sharpens the image.However, it is difficult to check the effect of changes by modifying the parameters in the QA screen.

EDGE ENHANCE Screen

1 Enable edge enhancement.

Touch and highlight (white character) [EDGE ENHANCEMENT].

2 Set the degree of enhancement.

Touch or to select a setting from 1 to 11.The displayed value on the left is the saved value, and the value on the right is the modified value.The effect is proportional to the setting value.Higher values result in higher emphasis, and lower values result in lower emphasis.

3 Set the enhancement frequency.

Touch or to select a setting from 1 to 11.The displayed value on the left is the saved value, and the value on the right is the modified value.The larger the value, the clearer the definition of detailed (high frequency) structures, such as bone trabeculae. Low frequency values result in clearer definition of larger (low frequency) structures, such as soft tissue.

7.6 DEP (Display Enhancement Processing)

NOTE: When parameters are set to excessively high values, artifacts may be generated or effective image information may be degraded.If you think the image looks as if it has been over-processed, set the parameters to lower values, or void the process.

NOTE: If you wish to adjust both the LUT (→ page 70) and the DEP, void the DEP by touching the DEP button in DEP mode so the word is not highlighted. Adjust the LUT of the main area of interest in LUT mode first. Then, adjust the area of lesser interest with DEP parameters.

DEP widens the range that can be viewed on film or monitor by narrowing the pixel value range of areas of lesser interest without changing the view of the microstructure of the area of main interest.The effect of changes by modifying the parameters can be checked in the QA screen.

DEP Screen

1 Enable DEP.

Touch and highlight (white character) [DEP].

2 Set the high density effect.

Touch or to select a setting from +10 to -10.The value on the left is the value analyzed automatically (DEP analysis value). The value on the right is the effectivity that will be added to the analyzed value on the left side (table below).The larger the number, the stronger the processing.However, too large a value can make the parts of the image not covered by the patient very light, resulting in a poorer image.

CXDI Adjustment

8. Calibration

9. Self test

– 96 –

Notes on CXDI Adjustment

Before Calibration1. The temperature in the room when performing calibration must be the same as during an ordinary exposure.

Otherwise, you will not be able to obtain a uniform image.2. Wait for the sensor unit to stabilize before calibrating the instrument (approximately 30 minutes after turning

ON the power).3. Do not use a AEC (Automatic Exposure Control).4. A more uniform image may be obtained by setting the tube voltage and exposure time to values used

frequently during the actual exposures.5. Uniformity of image may be improved when the exposure is performed many times.

Four or more exposures should be done.6. If the sensor unit’s grid is detachable, also refer to the hardware operating manual.7. When a multiple number of sensors are used, perform the calibration for each of the sensors.8. When a single sensor is set for a multiple number of sensor units, perform the calibration for each of the

units.9. With the CXDI-40G COMPACT, do not remove the grid.

When calibration is to be performed, ask the service technician to do this job.

During Calibration1. Align the system as for an ordinary exposure, such as when the whole imaging area of the sensor unit will

be exposed.Although calibration can be performed even by irradiating part of the sensor unit, you will not be able to obtain a normal image for the areas that have not been irradiated by x-rays.

2. Do not put any lead mark on the sensor unit, or place any object between the sensor unit and the X-ray tube.Such an object will appear on all the pictures.

3. If the message “Calibration Error.” “Too Much/Little Dose. Or collimator is used.” is displayed, perform calibration again after adjusting the X-ray exposure condition.

During Self Test1. Perform the exposure using the same settings as calibration for the exposure parameter settings and grid

usage. With the CXDI-40G COMPACT, proceed to undertake the self test while leaving the grid in place.2. In some cases, an error may be detected in TEST1 due to unintended exposure of the ion chamber or photo

timer inside the sensor unit. This is not a malfunction, and you may continue usage as before.3. Align the system as for an ordinary exposure, such as when the whole imaging area of the sensor unit will

be exposed.If a partial exposure occurs, an error may be detected.

4. Do not put any lead mark on the sensor unit, or place any object between the sensor unit and the X-ray tube.If an object obstructs exposure, an error may be detected.

8. CalibrationCalibration is used to adjust the X-ray sensitivity of the sensor unit.Perform calibration in the following cases.1. When a warning message is displayed2. When the exposure conditions are changed significantly3. When the density of the image does not appear as desired
