The invention relates to a head-mounted visualization system having a wearing system, at least one light-transmissive optical system, an image generation device designed to generate image information based on the image data supplied to the image generation device, wherein the optical system is designed to supply image information generated by the image generation device to a person wearing the visualization system, and a polarization unit designed to polarize light penetrating the optical system differently in two spatial regions. The invention further relates to a surgical visualization system having such a head-mounted visualization system and to a visualization method for a surgical environment.

Head-mounted visualization system

The invention relates to a method for operating a visualization system in a surgical application, wherein at least one image representation of a region to be operated on and/or operated on is captured by means of a capturing device, wherein the at least one image representation is displayed on a main display device, wherein a pose of a visualization device that can be worn on the head relative to a display surface of the main display device is captured by means of a pose sensor system, and wherein at least one three-dimensional augmentation information item corresponding to the at least one image representation displayed is generated and/or provided and is displayed on a display device of the visualization device, wherein the augmentation information item is generated and/or provided in consideration of the captured pose in such a way that the at least one image representation displayed on the main display device is extended into a three-dimensional region by the at least one three-dimensional augmentation information item corresponding to said at least one image representation. Furthermore, the invention relates to a visualization system for a surgical application.

Method for operating a visualization system in a surgical application, and visualization system for a surgical application

A head-mounted visualization unit is provided with an at least partially light-transmissive optical system. The optical system has a first optical channel assigned to a first eye of a user and a second optical channel assigned to a second eye of the user. The first optical channel is substantially transmissive to optical radiation of a first polarization and substantially opaque to optical radiation of a second polarization, with the first polarization substantially orthogonal to the second polarization. The second optical channel is substantially transmissive to optical radiation of the second polarization and substantially opaque to optical radiation of the first polarization. A polarizer and a light attenuator are arranged in the first optical channel. The light attenuator is arranged downstream of the polarizer in a direction toward the first eye of the user.

Head-mounted visualization unit and visualization system comprising light-transmissive optical system

The invention relates to a method for operating a visualization system in a surgical application, wherein a registration device of the visualization system provides a video data stream with a first image size as an output, wherein an image excerpt of the video data stream with a second image size that has been reduced in relation to the first image size is transmitted to a head-mounted visualization device via a communications link and is displayed on a display device of the visualization device, wherein a viewing direction of a user is registered by means of a sensor system, and wherein the image excerpt of the video data stream is defined on the basis of the registered viewing direction. Further, the invention relates to a visualization system.
