ABSTRACT:
The invention provides an operating microscope for observing an operating field and also for producing a three-dimensional visualization of image data of the operating field or also of a vicinity of the operating field. The user of the operating microscope, for example a surgeon, can observe a three-dimensional visualization of image data during use of the operating microscope, said image data having been acquired by computerized tomography (CT) or magnetic resonance imaging (MRI) and being stored in an image memory. Preferably, an image processing unit derives a stereoscopic image of the operating field from the stored image data, which stereoscopic image is coupled into the binocular of the operating microscope. The user can then optionally observe the actual operating field or a perspective image formed by means of the registered image data. The operating microscope comprises a system of position sensors for determining the setting of the operating microscope and for applying the setting to the image processing unit so that a stereoscopic image is formed with settings, such as viewing angle and magnification, corresponding to the setting of the operating microscope.
