Learning objectives


To have standardised terminology across all DR equipment in one Hospital Trust which will act as a visual indicator to the radiographer that the image is correctly exposed and within national Dose Reference Levels (DRL’s) 



[i] To test if EI and DI was appropriately calibrated  in 8 DR rooms across multiple sites in a busy Hospital Trust in the UK.

[ii] To investigate if IEC 62494-1 would give the radiographer a reliable visual indicator of a correctly exposed image.

[iii] To identify if examination doses for the five body parts were below national DRLs.
