ABSTRACT
Quality assurance (QA) throughout radiology departments is commonplace – for modalities utilising ionising radiation, tasks such as checking X-ray tube output, exposure duration plus collimation/beam accuracy, together with performing test studies on contrast phantoms are routine. In modalities utilising non-ionising radiation, similar tests are carried out, but are tailored to the imaging parameters involved. The hardware, software, and applications underpinning the imaging informatics speciality require similar attention to ensure that images remain available and accessible when needed. Image display monitors for the purposes of viewing radiological imaging are broken down into two main types: diagnostic display monitors and review monitors. Many diagnostic monitors are now designed to carry out basic daily self-tests, reporting back to a piece of monitoring software located on a server within the healthcare institution in order to supplement the more comprehensive medical physics testing and provide faster alerting to monitors out of calibration.
