1. QA/QC of Image Display Equipment

2. Film Viewing Equipment ("Viewing Boxes")
The quality and characteristics of the viewing equipment play a decisive role in the recognition of diagnostic details in the radiological image. The measurable, physical parameter for viewing equipment is the light stream (light quantity) which is emitted from the viewing surface of the equipment.

3. If the light stream L (lat
If the light stream L (lat. Lumen) is put in relation to the light emitting surface, you produce the measurement parameter Luminance L: L = Candela / Square meter (cd/m2).

4. LUMINANCE
A properly exposed X-Ray film has a mid-optical density of 1.2 To be able to diagnose details in the lower density range of the density curve (D = 0.3 – 0.6), the luminance of the viewing device must be able to be reduced.

5. To view high density (Dopt > 2
To view high density (Dopt > 2.2) areas of X-Ray films, a strong light source with an iris shutter (“hot light”) is needed. This light source must have a luminance of at least 5000 cd/m2. Due to their great importance in making diagnostic details of radiographs visible, all viewing devices must undergo an acceptance test and routine constancy tests.

6. Repeat tests for viewing devices, which are routinely used for diagnosis:

8. DIN test tool
It stands for "Deutsches Institut für Normung", meaning "German institute for standardisation".
DIN stands for "Deutsches Institut für Normung", meaning "German institute for standardisation". DIN standards that begin with "DIN V" ("Vornorm", meaning "pre-issue") are the result of standardization work, but because of certain reservations on the content or because of the divergent compared to a standard installation procedure of DIN, they are not yet published standards.

10. Applications of using din test tool
Ideal for use as a preventive maintenance quality control test tool, the “DIN” Test Tool can also be used to take regularly scheduled measured data points from the image, such as line pair resolution measurements, ROIs (regions of interest) and geometry symmetry . Measurements/angle can be used to evaluate monitor, as well as printed film image quality .

11. Society of Motion Picture and Television Engineers
Is founded in 1916 as the Society of Motion Picture Engineers or SMPE is an international professional association, based in the United States of America of engineers working in the motion imaging industries.
An internationally recognized standards organizations, SMPTE has more than 600 Standards, Recommended Practices and Engineering Guidelines for television production, filmmaking, digital cinema, audio recording, information technology, and medical imaging.

12.  Society of Motion Picture and Television Engineers
The Society of Motion Picture and Television Engineers (SMPTE (/ˈsɪmptiː/, rarely /ˈsʌmptiː/), founded in 1916 as the Society of Motion Picture Engineers or SMPE,[1] is an international professional association, based in the United States of America, of engineers working in the motion imaging industries. An internationally recognized standards organizations, SMPTE has more than 600 Standards, Recommended Practices and Engineering Guidelines for television production, filmmaking, digital cinema, audio recording, information technology, and medical imaging. In addition to development and publication of technical standard documents, SMPTE publishes the SMPTE Motion Imaging Journal, provides networking opportunities for its members, produces academic conferences and exhibitions, and performs other industry-related functions.
