Abstract (en)

[origin: WO9938449A1] Camera systems in combination with data processors, image scan data, and computers and associated graphic display provide tracking of instruments, objects, patients, and apparatus in a surgical, diagnostic, or treatment setting. Optically detectable objects are connected to instrumentation, a patient, or a clinician to track their position in space by optical detection systems and methods. The recognition of instruments by patterns of optically detectable structures provides data on three-dimensional position, orientation, and instrument type. Passive or active optical detection is possible via various light sources, reflectors, and pattern structures applicable in various clinical contexts.
