14HK701G Flat Panel Digital X-ray Detector User Manual Part 3

 

How to acquire bright image with X-Ray shot. This procedure is also applied for pediatric patient. X-ray generator connection is explained in this manual page from 46 to 48. 1 Click the Acquisition Button next to Bright Image(s) text. 46 ENGLISH 2 Implement X-ray Shot. Calibration SW will wait X-Ray acknowledge signal from DXD and it will display waiting sign. 47 ENGLISH 3 Acquired bright image is displayed in list view, please check its name and median value. Actual file is saved Image folder in the workspace. NOTE These acquisition steps are all same to User BPM, Validation and EI image acquisition. Calibration SW support Window level adjustment, but does not support other image post-processing function. The process of obtaining the image for pediatric patients is same with other patients. 48 ENGLISH CALIBRATION SOFTWARE To ensure that optimal image quality is obtained from the detector, the detector must be calibrated. The Calibration Software generates and verifies the values necessary for calibration. NOTE To ensure optimal image quality, you should calibrate every month for the first three months after the purchase and half-yearly calibration thereafter. It is recommended that you leave the detector on for 15 minutes before calibrating. The default value of Calibration Software could be changed depends on Detector. Calibration Software The features of the Calibration Software include Settings, Calibration, User BPM, Validation and Exposure Index. 49 ENGLISH Settings Settings include DXD settings, Calibration SW settings and Firmware Update. DXD: Configures the settings required to obtain calibration images and detector settings. 50 ENGLISH Calibration SW: Configures the settings required for to calibrate software algorithms. 51 ENGLISH Firmware Update: Checks the firmware version of the detector or performs the firmware update.

<Settings Screen: Firmware Update>

52 ENGLISH Calibration Calibration involves the following procedures. Dark Image and Bright Image are obtained from the detector.

- Dark Image: An image obtained without generating X-rays.

- Bright Image: An image obtained by generating X-rays without a phantom or any other object on the detector. Generate Avg dark, Offset, and Gain: Used for Corrected Image calculations.

- Corrected Image: An image generated by applying calibration results to a raw image. Generate Bad Pixel Map: Bad pixel values are calibrated using surrounding pixel values.
