Editing Scanco Administration (section)

====Update a scan with new calibration or BHC====
If the QC1 range was out of range but it was not possible to update the system calibration before scanning, you can update the scan with the new density calibration (i.e., slope and intercept).  It is also possible to change the beam hardening correction that is applied (e.g., from 200 mg HA/cm3 to 1200 mg HA/cm3).

Use the UCT_EXT_HEADER_ADD_CALIB program to update an RSQ and, if appropriate, repeat for the ISQ.
