Definition of Patient dose optimisation
Check what you remember
Read the wording for your board, then hide it and explain Patient dose optimisation in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Digital data can be windowed and enhanced after exposure without repeating the scan, and lower retake rates and reduced repeat exposures follow from immediate checking of image quality, lowering overall patient dose.
