However, soft tissue in a high density area can be observed more clearly. This is the version of the CHEST gray scale curve that supports high contrast. This is the version of the BONE #1 gray scale curve that supports high contrast. This is the version of the BONE #2 gray scale curve that supports high contrast. 3 Set the REX. Touch or to select a setting from1 to Or, touch the frame and enter the value from the ten key window. The larger the number, the lighter the entire image. The smaller the number, the darker the entire image. REX usage examples To observe over time a patient whose image has been taken before, take the image using the same exposure conditions, contrast, and gray scale curve as before. You can also observe under the same conditions by setting the gray scale to REX ADJUST. and setting the REX to the same value as before. 74

83 7. Processing the Image (QA Mode Screen) REX When REX is adjusted, the LUT graph shifts in the pixel value direction (right figure). Density An enlarged graph is shown below. DOWN UP REX Pixel Value Extracted analysis value position Analysis value = 1220 Density = 1.9 D (Second quadrant) Density Low X-ray dose (High sensitivity) Density = 1.9 D Reference density = 0.75 D Gray scale curve High X-ray dose (Low sensitivity) (First quadrant) X-Ray dose (Third quadrant) REX = 375 Pixel value (12 bit log) (Fourth quadrant) Analysis value = 1220 Sensor Characteristics Curve Sensor output (14 bit linear) Logarithm conversion curve 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 curve The 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 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 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. 75

84 7. Processing the Image (QA Mode Screen) 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. 1 Enable 2 Set 3 Set edge enhancement.

The settings and corresponding frequencies are shown below: Table 7.5.1: Setting Values Enhancement Frequency Setting FREQUENCY (lp/mm)

85 7. Processing the Image (QA Mode Screen) 7.6 DEP (Display Enhancement Processing) NOTE: 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. 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. 1 Enable 2 Set DEP. DEP Screen Touch and highlight (white character) [DEP]. the high density effect.

103 CXDI Adjustment 8. Calibration 9. Self test

104 Notes on CXDI Adjustment Before Calibration 1. 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 Calibration 1. 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 Test 1. 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. 96

105 8. Calibration Calibration is used to adjust the X-ray sensitivity of the sensor unit. Perform calibration in the following cases. 1. When a warning message is displayed 2. When the exposure conditions are changed significantly 3. When the density of the image does not appear as desired 8.1 Setting the Parameters 1 Display the calibration screen.
