In order to assist medical personnel in the generation of a medical diagnosis, context-related criteria are automatically determined from available case-related primary information, and using these context-related criteria context-related secondary information is automatically filtered out from a secondary data source and is displayed in an information portal on a display element for further processing by medical personnel. Case-related secondary information that support the personnel in the generation of an applicable diagnosis of the current case thus are automatically provided to the medical personnel via this measure.
摘要:
An optical element particularly elements of IR optics comprises a system of a plurality of infrared transmitting optically effective thin layers of substances. The substances are chosen from the group: germanium, zinc selenide, zinc sulfide, chalcogenide glasses, thorium fluoride, yttrium fluoride, and praseodymium fluoride. The layers are applied to an infrared transmitting substrate of a material of the group: germanium, zinc selenide, zinc sulfide and chalcogenide glasses. An intermediate layer is disposed between the thin layers and the infrared transmitting substrate and this has a maximum thickness of 100 nm and comprises a material of the group: hafnium oxide, yttrium oxide, and scandium oxide.
