Abstract: A method is disclosed for displaying image data of body regions of a patient using a medical imaging system including a first imaging apparatus and a positron emission tomography apparatus, the body regions being prone to dementia. The method includes provision of first image data recorded using the first imaging apparatus; provision of second image data recorded using the positron emission tomography apparatus, the first image data and the second image data being recorded simultaneously or at short intervals of time consecutively; segmentation of the first image data in respect of body regions prone to dementia, a segmentation mask being generated to this end on the basis of the first image data; generation of results data, the results data including a selection of voxels in the second image data made using the segmentation mask; and display of the results data.

Abstract: Method and system for identifying a user A method for identifying a user, in which at least one person-specific feature of the user is requested by a central server and is transmitted to the central server by an input appliance of a user computer device via a telecommunication link, in particular over the Internet, and is compared with stored user data, the at least one person-specific feature being selected by the central server on the basis of the random principle from a plurality of features recorded in a first feature group comprising the print from at least one finger and/or the image of the iris of at least one eye and/or a voice sample and/or a sample signature and/or an image of at least part of the user and/or the genetic fingerprint and in a second feature group comprising the user name and/or the date of birth and/or a user number and/or a secret number.

Abstract: The invention provides a system and method for operating a communication system in which a central computer recognizes that a customer computer has retrieved an offer page for at least one offer from a supplier, receives at least one report of operating actions performed on the customer computer relative to the offer page, and evaluates the reported operating actions.

Abstract: A communication system and method wherein a central unit stores at least one offer page that can be retrieved by a customer communication unit, wherein when the offer page indicates an advice requirement relating to the offer, the communication system reports the advice requirement in real time to the supplier communication unit, which responds to the customer communication unit in real time.
