1.22.3.11 - Radiographic Faults
taking a good radiograph
collimation
exposure
centring
labelling
positioning
artefacts
common faults
under-exposure
increase exposure
gross over-exposure
reduce exposure
damaged/dirty plates
clean plates regularly and immediately if marks noticed
dirty light guide
avoid dirt/hairs entering processor
clean if artefacts present
ghosting
erase plates daily/check processor erasure light to avoid
border artefacts
halo around opaque objects
make sure correct software algorithm is used
improving an image where you cant see detail
correct centring and collimation will improve definition
choose the right software settings
e.g. not abdominal for a thorax radiograph
positioning: adequate restraint and accurate positioning
labelling: use an L/R label
no lead gloves in primary beam
unsafe radiographs
collimation
only include area of interest
centring
centre in the area of interest
exposure
decrease exposure to correct expose plate/sensor
artefacts
never place gloved hands in the primary beam
labelling
use and L/R marker in every radiograph
summary
Being able to identify common radiographic faults will help you to correct them and avoid them in the future
It is very tempting to try to make a diagnosis regardless on poor quality radiographs – however, you will miss pathology that would be clearly visible in a good quality image
You must always assess this before trying to interpret the image
It is essential to recognise when an image is not of adequate diagnostic quality
