Enable or Disable Technical Mode
Technical Mode is a special setting that configures the system for image quality testing and detector
calibration. When Technical Mode is enabled, DEI is calculated using the central area of the image (512
pixels x 512 pixels) regardless of the imaged anatomy.
IMPORTANT!: Do not acquire exam images when Technical Mode is enabled. The use of Technical Mode
is reserved for image testing and calibration purposes only.
The checkbox (Figure 10-21) indicates if Technical Mode is enabled. Check or uncheck the box as
appropriate and press [SAVE] to apply the change and close the screen.
