This option allows you to disable or enable internal commands. To disable a command, precede the command name with a minus [-]. To re-enable a command, precede it with a plus [+]. For example, to disable the internal LIST command to force TCC to use an external command:

setdos /i-list

To re-enable all disabled commands use /I*.

Converting CT Data to Hounsfield Units

The formula is:

hu = pixel_value * slope + intercept

Normally, these values are stored in the DICOM file itself. The tags are generally called the Rescale Slope and Rescale Intercept, and typically have values of 1 and -1024, respectively.
