The project team managed to improving image quality and intraoperative imaging doses through the use of optimised positioning aids. Vinyl-covered foam positioning aids were implemented in the operating theatre to replace the use of dense jellies and saline bags. The team was able to mimic the size, shape and density of the jellies with help from the surgeons to create the foam sponges.

Aim
To educate staff on radiation safety and basic radiation principles to improve understanding around the importance of their choices when setting up for theatre cases requiring intraoperative imaging. Through collaboration with specialities, design an alternative positioning aid which improves image quality and decreases patient doses.
Benefits
Benefit to the patient by reducing the received dose of radiation significantly.
Background
The project's foundation was to optimise image quality and reduce radiation doses to paediatric patients in the operating suite. Previous routine practice in the operating suite had staff using dense jelly positioning aids over anatomy to be imaged by medical imaging staff. These aids reduced image quality and increased the dose to the patient. By working together we were able to get the best of both worlds – an aid that held patients in the required position, did not impact image quality and had a negligible increase in dose to the patient.
