Background/introduction

The medical field over the years has benefited enormously from the use of X-ray radiation with lots of applications in diagnosis and therapy. The use of fluoroscopy has become commonplace and, in some cases, indispensable in the daily clinical practice of different units (1). C-arm units are portable and allow to perform multiple different fluoroscopic examinations outside the radiology department. Its use in orthopaedic surgery is increasing rapidly as surgery transitions to minimal-access surgery. With less direct visualization, surgery is being conducted with fluoroscopic guidance...

Description of activity and work performed

Material and Methods The study has been performed at the operating theatre of a University Paediatric Hospital. Three c-arm units are available at the surgical area: GE Brivo 785, Philips BV Libra and Siemens Siremobil. The last mentioned does not have the capability of exporting images to PACS system, so it does not take part of the study. The other units do export stored images and the technical parameters associated with them to the PACS. The data that have been recorded from the PACS system...

Conclusion and recommendations

A first attempt of DRLs establishment has been made, in order to analyse and if possible optimise paediatric patient doses in such procedures which definitely are not negligible, but somehow comparable to other common procedures as MCU. Automatic extraction of data from PACS systems would facilitate bigger statistic samples thus reducing scattering of doses and refining obtained DRLs.
