摘要： A system for precision guidance of surgical procedures on a patient is disclosed. Aspects of the system may include: a three-dimensional digital representation of a pre-procedural geometry of a relevant part of the patient, a three-dimensional digital representation of an intended post-procedural geometry of the relevant part of the patient including any implant or other structures intended to be attached to the patient, and a movable electro-optical (EO) camera mounted in a known position and orientation relative to a surgeon, such as a head mount. Further aspects of the system may include a first carrier comprising at least 3 targets to be observed by the EO camera, wherein the first carrier may be mounted in a known first position and first orientation relative to the relevant part of the patient, and a second carrier comprising at least 3 targets to be observed by the EO camera, wherein the second carrier may be mounted in a known second position and second orientation relative to an implant or surgical instrument. Embodiments of the system may include a computer for calculating, based on observations from the EO camera, relative positions of the first and second carriers and of the EO camera. Embodiments of the system may also include software, residing on the computer, configured to calculate a relevant projection of a digital representation of the patient to be displayed in order for the displayed projection to match with the surgeon's current physical view of the patient.

摘要： A weapon platform for accurately locating and/or tracking enemy targets is described. The weapon platform may include an electro-optical sensor unit comprising one or more sensors, an electro-optical camera, and a plurality of local targets located within the weapon system. The camera may observe the local targets and output information regarding the spatial relationship between the sensor unit and a weapon connected to the weapon platform. The local targets may be connected to the weapon, to the weapon platform, and/or to the sensor unit. Using the information regarding the spatial relationship, the weapon may be steered toward enemy targets that are located using the sensor unit.

摘要： A system for ensuring precision in medical treatment of a patient comprising one or more clusters of targets attached to a patient, a strapping mechanism or a carrier defining a patient-fixed coordinate system. The system also includes a first electro-optical measurement system for observing the one or more clusters of targets and local reference markers of an imaging system to determine the relationship between the patient-fixed coordinate system and a coordinate system of the imaging system, whereby a location to be treated inside the patient can be calculated in the patient-fixed coordinate system. The system further includes a second electro-optical measurement system for observing the one or more clusters of targets and local reference markers of a treatment system, whereby the location to be treated inside the patient can be calculated in a coordinate system of a treatment system.
