SURGICAL MICROSCOPE FOR GENERATING AN OBSERVATION IMAGE OF AN OBJECT REGION

摘要

A surgical microscope for producing an observation image of an object region for an observer is provided. The surgical microscope includes an image acquisition device to acquire an image of the object region, a display device, an image processing and control device, a computer unit, a switchable imaging optical unit, an eyepiece and an optical observation beam path. The switchable imaging optical unit feeds the observation image to the eyepiece via the optical observation beam path in a first switching state. In a second switching state, the switchable imaging optical unit interrupts the optical observation beam path between the object region and the eyepiece to display an acquired image in the eyepiece and to electronically superpose the object region image data at a predefined position onto the image of the object region.

1. A surgical microscope for generating an observation image of an object region for an observer, the surgical microscope comprising:
an image acquisition device configured to acquire an image of the object region; a display device; an image processing and control device connected to said image acquisition device and to said display device to visualize the image of the object region acquired by said image acquisition device; a computer unit connected to said image processing and control device; said computer unit being configured to provide object region image data to said display device to be displayed on said display device; said object region image data being obtained by an imaging method; a switchable imaging optical unit having a first switching state and a second switching state; an eyepiece; an optical observation beam path being a purely optical observation part and being superposable with said object region image data at a predefined position; said switchable imaging optical unit being configured to feed the observation image of the object region to said eyepiece via said optical observation beam path being superposable with said object region image data at said predefined position when said switchable imaging optical unit is in said first switching state; said switchable imaging optical unit being configured to interrupt said optical observation beam path between the object region and said eyepiece in order to display an image from said optical observation beam path of the object region in said eyepiece that is acquired by said image acquisition device and displayed by said display device when said switchable imaging optical unit is in said second switching state; and, said image processing and control device being configured to electronically superpose the object region image data obtained by the imaging method and provided by the computer unit at the predefined position onto the image of the object region displayed by said display device in said eyepiece when said switchable imaging optical unit is in said second switching state.
