A method of operating a surgical microscopy system, a motion sensing system for a surgical microscopy system, and an operating microscopy system

摘要

A method of operating a surgical microscopy system (1), the surgical microscopy system (1) comprising: - a microscope optics (21) designed to image an object area for consideration during surgery, - a movement device (18) configured therefor is to move the microscope optics (21) such that a position of the object area is changed, - at least one digital image recording device (23, 24) with a matrix of sensor elements, wherein the image recording device (23, 24) a local radiation distribution due to Detected radiation, which emanates from a detection structure (28, 29), (a) wherein the image recording device (23, 24) either with the microscope optics (21) and is moved with movement of the microscope optics (21), wherein the image recording device (23, 24) detects, by the detected radiation, the detection structure (28, 29) arranged separately from the microscope optics (21), ie e is not moved during movement of the microscope optics (21), detected by at least one recording image, (b) or wherein the image recording device (23, 24) is arranged separately from the microscope optics (21), with movement of the microscope optics (21) is not moved and the detection structure (28, 29) formed by the microscope optics (21) and / or by at least one fixedly connected to the microscope optics (21) part and / or on the microscope Optics (21) and / or on which at least one fixed to the microscope optics (21) connected part is detected by at least one recording image, wherein using information about an actual appearance of the detection structure (28, 29), ie Information about an appearance of the detection structure (31; 41) in a non-moving state, by evaluating differences of the at least one recorded image to the actual appearance of the detection structure (28, 29) by a timing of the local radiation distribution within the respective integration time interval individual sensor elements of the image recording device (23, 24) during a relative movement of the image recording device (23, 24) and the detection structure (28, 29) arise, a speed of the relative movement of the image recording device (23, 24) and the detection structure (28, 29) is determined ,
