Development of a digital platform to aid chest radiographic image interpretation

Training has been provided in a variety of methods and tested for its effect on image interpretation accuracy. Studies have attempted to evaluate the effect of eye tracking based feedback/training on lung nodule detection by assessing the interpretation performance of radiographers. These researchers have provided tailored feedback using eye tracking data from the participant (expert or novice) and attempted to evaluate whether this eye-gaze based feedback had a positive impact on the participant’s performance. The feedback based on eye tracking technology proved to have a positive effect since significant improvements were found. However, no studies have been completed to test participants on their detection of a range of chest pathologies and with the involvement of training based on the eye tracking. Published guidelines and websites make recommendations about how to interpret a radiographic image. Often trainee reporting clinicians combine advice given in this guidance with a variety of recommended search techniques to form their own image interpretation search strategy. However, despite this, no optimal standardised systematic approach for chest image interpretation has been recommended using an evidence base. We are also not aware of any training tool which uses eye tracking technology to communicate effective search strategies to trainees.
