These are gamma functions that are shifted to take
into account the non-zero luminance of an LCD
panel when driven with a “black” signal. They are
especially useful in CT applications to improve the

DICOM DICOM (Digital Imaging and Communications
in Medicine) is an international standard that

recommends selecting the DICOM display function
for most medical viewing applications.
