Publication number: 20230350177Abstract: Provided is a robotic microscope that includes an optical system being moveable in one or more spatial directions and an actuator configured to move the optical system in the spatial directions. The microscope includes a capacitive sensor with an electrode coupled to at least a part of the optical system, the capacitive sensor configured to provide a sensor signal indicative of a capacitance in a vicinity of the electrode. The microscope further includes control circuitry configured to determine, based on processing the sensor signal, at least one capacitance value for the capacitance, and configured to actuate, based on comparing at least one capacitance value with at least one reference value for the capacitance, the actuator to move the optical system such that a distance between a user's head and part of the optical system and/or an orientation of the user's head and part of the optical system is substantially constant.Type: ApplicationFiled: January 8, 2020Publication date: November 2, 2023Inventors: Stefan VILSMEIER, Sven FLOSSMANN

Publication number: 20220405935Abstract: The disclosed method encompasses using an augmented reality device to blend in augmentation information including for example atlas information. The atlas information may be display separately from or in addition to a patient image (planning image). In order to display the atlas information in a proper position relative to the patient image, the two data sets are registered to one another. This registration can serve for generating a diversity of atlas-based image supplements, for example alternatively or additionally to the foregoing for displaying a segmentation of the patient image in the augmented reality image. The disclosed method is usable in a medical environment such as for surgery or radiotherapy.Type: ApplicationFiled: August 19, 2022Publication date: December 22, 2022Inventors: Sven Flossmann, Samuel Kerschbaumer, Nils Frielinghaus, Christoffer Hamilton

Patent number: 10987190Abstract: This document relates to a medical application of augmented reality in which areal image shows a medical device, or at least a part thereof. In an exemplary application, the real image further shows at least a part of a patient's body which is (to be) treated using the medical device. A part of the medical device might not be visible in the real image, for example because it extends into or behind the patient's body. In this case, the virtual image can comprise an augmentation of the medical device, which, for example, represents at least the part of the medical device which is invisible in the real image. This document in particular addresses a correct alignment of the augmentation with the medical device.Type: GrantFiled: May 9, 2017Date of Patent: April 27, 2021Assignee: BRAINLAB AGInventors: Sven Flossmann, Sebastian Stopp
