Ultrasonography is widely used for screening of traumas or disorders of internal organs noninvasively, while its diagnostic accuracy depends on skills of physicians. Therefore, trainings of inexperienced physicians are important. The purpose of this study is to propose a novel training system for ultrasonography by integrating simulators (ultrasound phantom) and image processing techniques.
This system can provide feedback to the trainee based on recognition of target organs in ultrasound images after role-plays of ultrasound examinations on the simulator. An experiment using simulator for FAST (Focused Assessment with Sonography for Trauma) was conducted and this algorithm could recognize the target organs with the 96-100% recognition rates.
We conclude that proposed method could be useful not only for evaluations after the training but also for real-time feedback during the each training trails.
