Grayscale Standard Display Function

DICOM image consistency deals with displaying the images in an identical manner on soft and hard copy devices, using a standard mapping from digital driving levels to luminance on a

monitor or density on hard copy.

 

Image display consistency is a major issue that hampers the implementation of PACS using softcopy viewing. The key to preserving the image quality of a display is to calibrate the monitor at regular intervals. There is no ideal display characteristic curve for mapping digital driving levels into luminance values. However there is a gold standard that could be adhered to.

 

This characteristic curve is generated by mapping just noticeable differences (JNDs) onto the light output (luminance) of a monitor or onto the optical density of a film. The resulting curve is called the Grayscale Standard Display Function (GSDF).

 

Using this standard, monitors and printers can be calibrated.
