摘要： 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.

摘要： A method of operating a surgical microscope includes detecting a position of a user, and setting a rotation angle of a camera about its main axis such that it is between a first angle and a second angle. The first angle is the rotation angle required to display a first straight object as a vertical line, and the second angle is the rotation angle required to display a second straight object as a horizontal line. The first object extends along a first line arranged in a vertical plane containing a line connecting the position of the user with the field of view. The first line is horizontal and traverses the field of view. The second object extends along a second line traversing the field of view. The second line is horizontal and perpendicular to the first line.

摘要： A system and a method for optically detecting a pose of at least one instrument in an operating theater are provided. The method includes determining pose information of the at least one instrument with an optical pose detection device of a surgical microscope or with a microscope-external optical pose detection device, determining whether the pose information is biunique or whether a biunique determination of the pose of the instrument is possible, and evaluating additional information for determining additional pose information, at least for a case where no biunique determination of the pose is possible.

摘要： A method of operating a surgical microscope includes detecting an amount of movement of a body portion of a user, and performing movements of a camera and changes in a magnification based on the detected movements of the body portion. The amounts of these movements and changes decrease with increasing magnification provided by the surgical microscope, they decrease with decreasing distance of the body portion of the user from the display, and they decrease with decreasing distance of the cameras from the field of view of the cameras.

摘要： A method of operating a surgical microscope includes detecting a direction of gaze of a user and detecting an amount of a movement of a head of the user. The movement of the head of the user is of a translatory movement type and a rotatory movement type. Amounts of movements or rotations of the camera or changes in the magnification are performed based on the detected amount of a movement of the head of the user.

摘要： A method for correcting a shading in a digital image of a three-dimensional observation object obtained by at least one image sensor of an optical observation device is provided. The three-dimensional observation object is illuminated by illumination light and an intensity distribution, and an inhomogeneity in an image brightness is present in the digital image of the three-dimensional observation object. The method includes ascertaining a topography of the three-dimensional observation object, correcting the inhomogeneity in the image brightness of the digital image based on the topography of the three-dimensional observation object and the intensity distribution of the illumination light. In addition, an optical observation system is provided to perform the method.

摘要： An apparatus for classifying a brain tissue area as functional or non-functional by a stimulation of the brain includes a receiver unit for receiving information about a performed stimulation, a recording device for recording images that represent the brain tissue area, a detection unit for detecting a change in perfusion in the brain tissue area, and a classification unit configured to determine with the information whether there is a correlation between the performed stimulation and the detected change in perfusion, and to classify the brain tissue area as functional or as non-functional. The recording device is an endomicroscope for recording endomicroscopic images of the brain tissue area with a spatial resolution better than 20 μm and a frame rate of at least 0.4 frames per second. The detection unit is configured to detect a change in perfusion based on the positions of certain tissue structures in the recorded images.
