How does calibration depend on scanner settings?
The calibration (and therefore OPTTAG_SLICESCALE value measurement) in general has to be independently performed for all scanner configurations: all X-Ray source kV’s and all bowtie filters (if any). Please note that you do all calibrations w/o PARTAG_MINUS1000 applied. When the calibration is done this tag is just shifting all values to get -1000 for air and 0 for water.
