To make an appropriate decision in surgery, surgeons estimate the location and shape of an invisible target organ based on their knowledge, experience and limited measurements (e.g. visual observation, 2D x-ray projection, electrocardiogram, and tactile sense). This project proposes a system allowing quantitative and accurate estimation, hence a safer surgery, by efficiently utilizing statistical learning of a large-scale surgical record database (referred to as “medical big data”). The improvement in surgical safety produced by the learning of medical records is expected to favorably impact on a controversial issue of the balance between patient’s benefit and privacy concerns. As a result, the system is expected to raise the social acceptability of medical big data, which encourages further collection of the training dataset, which ends up improving the system’s performance. This closed-loop data collection and utilization framework will be experimentally demonstrated in the project.
