A medical imaging device, comprising a illumination unit, can be configured to illuminate a tissue area with light from a first spectral range, comprising a range of visible wavelengths, and with light from a second spectral range, which is different from the first spectral range, an imaging unit, configured to detect light from the first spectral range and to generate a first image of the tissue area on the basis of the detected light from the first spectral range and furthermore configured to detect light from the second spectral range and to generate a second image of the tissue area on the basis of the detected light from the second spectral range, and a superposition unit, configured to generate a superimposed image on the basis of the first and second image in such a way that, in the superimposed image, on the basis of a visual highlighting, it is possible to identify whether and where the tissue area comprises highlight regions which are characterized by an increased emission of light from the second spectral range in comparison to other regions of the tissue area. The document furthermore relates to a method for image-based support for a medical intervention, and to a use of an imaging device in such a method.

Provided herein are systems and methods for simultaneous imaging and stimulation using a microscope system. The microscope system can have a relatively small size compared to an average microscope system. The microscope can comprise in part an imaging light source and a stimulation light source. Light from the imaging light source and the stimulation light source can be spectrally separated to reduce cross talk between the stimulation light and the imaging light.

Method for automatically setting at least a unit parameter for a medical unit or unit part with parameter values relating to a particular user. According to the method, a user is identified, a corresponding parameter set is selected and unit parameters are set with the selected parameter set. The preceding steps are only implemented when an authentication signal for activating the identification, selection and setting processes is received or present. The authentication signal can be based on use of a user priority database. The invention also relates to a corresponding medical unit and medical system.

Systems, devices, and methods for surgical illumination and imaging of ophthalmologic structures within a human eye are disclosed. In various embodiments, an emitter, imaging sensor, and a system control image processor are configured to irradiate ophthalmologic structures with near infrared light, detect near-infrared scatter from the irradiated ophthalmologic structures and visible light in real-time and generate or otherwise cause an image to be displayed on the user display that includes the detected near-infrared scatter from the irradiated ophthalmologic structures displayed in real-time. In one or more embodiments, the image is a virtual image of the irradiated ophthalmologic structures generated at least based on near-infrared light scattering coefficients of the irradiated ophthalmologic structures. In certain embodiments, the image displayed on the user display includes the detected near-infrared scatter from the irradiated ophthalmologic structures overlaid on a real-time view from a surgical microscope.

A stereoscopic imaging apparatus and platform are disclosed. An example stereoscopic imaging apparatus includes a main objective assembly and left and right lens sets defining respective parallel left and right optical paths from light that is received from the main objective assembly of a target surgical site.
