In medicine, guidelines for working with diagnostic images on computer monitors have been in place for a very long time. The NEMA Standard DICOM 3 in Part 14 is groundbreaking in this regard. Among other things, it implements the monitor characteristic curve according to Barten's findings (see Properties of the human eye) with the just noticeable difference (JND) as a gray scale display function (GSDF). In addition, technical terms are defined and the associated measurement methods are specified.

The German standard DIN 6868-157:2014 (successor to DIN 6868-15:2002) specifies the minimum requirements for image reproduction systems for the medical sector. The minimum requirements for image reproduction systems are described in chapters 8.4 and 8.5 of this standard. Depending on the application or body region, the specifications for minimum luminance, minimum luminance ratio, minimum pixel matrix, luminance characteristic curve, and display homogeneity are defined there. A distinction is made between viewing and diagnosis. Six room classes are defined. In addition, the scope and repetition rate of the checks are specified in tables.

Requirements for monitors in existing industrial radiography standards
Some industrial standards for digital radiography, e.g., ISO 17636-2, Section 10, or ASTM E 2698, specify requirements for monitors. These generally require a minimum brightness of 250 cd/m² and clear recognition of a 5% difference in brightness between 0% and 100% gray values, determined using a test image similar to SMPTE (Society for Motion Picture and Television Engineers), which is displayed in full format on the monitor.
