Towards Optimisation of Routine CT Quality Control

Mater Misericordiae University Hospital,
Dublin 7


Our experience has been that many factors conspire to make routine CT QC challenging. Obviously our hospital's single CT scanner is very busy therefore access is quite limited. In order to make the best use of our time with the machine, we developed techniques to migrate our mechanical and image quality measurements (including gantry tilt) for use with a Catphan 600™.

Established methods for the objective assessment of image quality tests in CT can be labour-intensive and time-consuming, since these are typically performed manually using image analysis software packages such as E-film or ImageJ. A Matlab™ package, featuring a Graphical User Interface was also developed for automating the analysis of DICOM images and production of a QA report. Results of image analysis along with on-site dose measurements are automatically transferred to a formatted Excel spreadsheet. This allows us to expedite our final report presentation.

Given the nature of this forum, we are interested to share our experiences and hopefully receive feedback on how can improve our techniques
