Patent ID: 8199876

Claim:
An imaging system comprising: an x-ray imaging system comprising a C-arm that is movably mounted at a support unit and a single x-ray source am a single x-ray detector mounted on said C-arm, said x-ray imaging system being configured to acquire at least two x-ray images of an examination subject respectively by irradiating the examination subject with x-rays directed at the subject from at least two different x-ray image origination points in space by movement of said C-arm with said single x-ray source and said single x-ray detector mounted thereon; an optical imaging system comprising at least two optical image acquisition units, a first of said optical image acquisition units being mounted for co-movement with said single x-ray source, and a second of said optical image acquisition units being mounted at said support unit, said optical system being configured to acquire at least two optical exposures of the examination subject respectively from at least two optical exposure origination points that respectively optically correspond to said at least two different x-ray image origination points; and a superimposition unit that superimposes the optical exposures with the x-ray images by superimposing the respective optical exposure, from among said at least two optical exposures, with the respective x-ray image, from among said at least two x-ray images, that has an x-ray image origination point corresponding to the optical exposure origination point of that optical exposure.
