Abstract: In a method and device for, generating computed tomography images of a periodically moving organ of an organism, the organ having regions with rest phases and movement phases and the rest phases of different regions ensuing at different points in time, an x-ray source is moved around the body of the organism to be examined to generate projections serving for the image generation during at least one rotation of the x-ray source around the subject to be examined and during a duration that is at least equal to a period of the motion. The projection data are analyzed as to whether the data were acquired during a rest phase or movement phase of a respective region of interest of the organ, and an image of the organ is reconstructed using only data acquired during a rest phase of a respective region of interest of the organ.

Abstract: A device for generating trigger signals for a medical apparatus, used for diagnosis and/or therapy, based on the respiratory activity of a patient includes a spirometer with a measurement transducer disposed therein for measuring respiratory air of a patient, and a signal generator connected to the transducer for generating trigger signals based on the respiratory measurement. A closure device can be provided in the spirometer in the respiratory path, which can be closed so that the flow respiratory air is briefly interrupted when a predetermined set value, for example obtained from the measured value, is reached.
