DICOM PS3.14 is a standard that controls which of the following?

• A. Dynamic range of the ADC
• B. Bit depth of the image acquisition system
• C. Minimum response time for the automatic exposure control (AEC) system
• D. Look-up table (LUT) of the monitor display

Answer: (D)

DICOM PS3.14 defines how grayscale images should be presented to the viewer by establishing a Grayscale Standard Display Function. This ensures that the brightness steps between gray levels are perceptually uniform across different displays. To achieve that consistency, displays rely on a look-up table that maps each pixel value to a calibrated luminance level in accordance with the GSDF. So the standard directly governs the monitor’s LUT used for display. The other options pertain to image capture hardware or exposure control timing, which are set before the image reaches the display and are not what this standard addresses.
