Patent number: 11766307Abstract: A method and device are for generating and displaying a map of a brain operating field, brain tissue areas associated with a stimulated brain function being marked in the map. In the method, during a measurement cycle a stimulation of a brain function is effected and a stimulation image of the brain operating field with the stimulated brain function is recorded, a reference image without the stimulated brain function is recorded, the stimulation image and the reference image are used to generate the map, and the map is displayed on a display. A plurality of cycles are performed. A new map is generated after each cycle following the first cycle. In order to generate the new map, the stimulation and reference images of one or more preceding cycles are used besides the images recorded in the cycle just carried out. At least the new map is displayed after each cycle.Type: GrantFiled: September 18, 2020Date of Patent: September 26, 2023Assignee: Carl Zeiss Meditec AGInventors: Konstantinos Filippatos, Roland Guckler, Annette Schreiber

Patent number: 11744466Abstract: An apparatus is for localizing brain tissue regions connected with a brain function in a brain operating field. The apparatus includes a stimulation apparatus and a localization unit with a camera. The stimulation apparatus is configured to carry out a number of stimulation cycles. Each cycle includes a stimulation phase during which the brain function is stimulated and a rest phase during which there is no stimulation of the brain function. The localization unit records at least one stimulation image with the stimulated brain function and at least one reference image without the stimulated brain function during each stimulation cycle and uses the recorded stimulation and reference images to localize the brain tissue regions connected with the stimulated brain function. The stimulation apparatus is configured to output a feedback signal to the localization unit with at least the start of a stimulation cycle being evident from the feedback signal.Type: GrantFiled: September 18, 2020Date of Patent: September 5, 2023Assignee: Carl Zeiss Meditec AGInventors: Christoph Hauger, Gerald Panitz, Roland Guckler
