The Digital Imaging and Communications in Medicine (DICOM) Part 14 defines the Grayscale Standard Display Function (GSDF) as the display function which guarantees the image display consistency for display devices. In recent years, the DICOM GSDF has been applied to a wide range of display devices. However, the display function on operators console monitors of digital diagnostic imaging modality is not clarified. Therefore, the consistency of a console monitor and other display monitors on a network may not be kept. The aim of this study is to analyze the display function on console monitors of CT /MRI. We measured the characteristic luminance response of the console Liquid Crystal Display (LCD) monitors using the Society of Motion Picture and Television Engineers (SMPTE) digital test pattern and deduced the display function. As a result of analysis, the display function of the LCD monitors were not the GSDF but γ = 2.2. This result suggests that a digital image on a LCD monitor of CT/MRI could look different on other display monitors. The DICOM GSDF must be applied to a wide range of display devices including console monitors of CT/MRI.
