•	DICOM Curve - The response curve follows the DICOM (Digital Imaging and Communications in 
Medicine) specification. This response curve is aimed at medical use, however it can be used for other 
applications. The goal of the DICOM response curve is to have a visually linear display response. 
Use  Scale  Factor -  The  DICOM  response  curve  shape  is  based  on  the  measured  black  level  and 
Intensity. If the black level or Intensity of the display changes,...
