A mobile assembly of mains electricity (AC-powered) devices intended for both pre- and intraoperative applications to: 1) process medical imaging data to create a patient-specific, three-dimensional (3-D) model to enable a surgeon to plan/prepare for a surgical procedure; and 2) connect to a separate surgical navigation system to extract and display real-time surgical navigation information (e.g., navigation pointer) within the same 3-D model during surgery. It includes hardware [e.g., personal computer (PC), monitors, medical grade keyboard) and dedicated software. It is capable of collecting patient demographics, which may be anonymised.
