  • Patent number: 8363916
    Abstract: At least one embodiment of the invention relates to a method for producing result images of an examination object, in the case of which a number of magnetic resonance images, determined by a magnetic resonance recording device, of the examination object are acquired, and radionuclide emission tomography image data, determined by a radionuclide emission tomography recording device, of the examination object are acquired. In at least one embodiment, the magnetic resonance images for determining contours of a target structure are then segmented, and the contours of the target structure are visualized in common with at least the radionuclide emission tomography image data that are assigned to picture elements located inside the target structure, and/or are stored for a later visualization.

  • Patent number: 8155978
    Abstract: A user predefines for a computer a retrieval instruction for primary data of a patient or of several patients. The computer accesses the primary data of this patient and outputs them to the user via a visual display device. The primary data comprise the primary image data recorded by way of a primary imaging modality and/or primary information derived from said primary image data. The computer automatically checks whether it is possible to access secondary data of this patient, which comprise the secondary image data recorded via a secondary imaging modality and/or secondary information derived from said secondary image data. In the affirmative case, the computer outputs a corresponding message to the user via the visual display device and/or by accessing at least a portion of the secondary data of this patient and outputting said data to the user via the visual display device.

  • Patent number: 8111888
    Abstract: At least one example embodiment discloses a method for automatically selecting a display mode for an image data record is provided. In the at least one example embodiment, spatially resolved values of a parameter are determined in a first image data record of the organ to be examined, with the parameter allowing an evaluation of a functionality of the organ to be examined. Thereupon a deviation of the determined values of the parameter from a tolerance range is localized. The result of the localization is saved, and a display mode of a second image data record is selected on the basis of the result of localization, with the second image data record being a 3D image data record. The second image data record is shown in the selected display mode.

  • Patent number: 8077941
    Abstract: In order to produce a contrast enhanced image data record of an examination region of a patient, a method is disclosed. In at least one embodiment, the method includes loading a first image data record of the examination region in the case of which healthy tissue is displayed with a lower intensity than blood and diseased tissue, and a second image data record of the examination region in the case of which blood is displayed with a lower intensity than healthy and diseased tissue. In at least one embodiment, the contrast enhanced image data record is produced by processing the first image data record and the second one, the processing including at least one arithmetic operation, and is thereupon displayed and/or stored.

  • Patent number: 7978891
    Abstract: In a method for generation of a medical image, starting from an acquired data set of an organ to be depicted, a magnification factor and/or an image section to be depicted are automatically determined dependent on the organ to be depicted. Based on this a medical image is generated from the data set. A data processing unit for medical images is fashioned for implementation of such a method and computer software implements such a method when it is executed on a data processing unit.

  • Publication number: 20100324409
    Abstract: In a method for determining the ventilation of a lung of an object under examination by magnetic resonance imaging, at least two first lung-representing image data sets are acquired at different intervals of the breathing phase. The density change of the lung tissue is automatically determined from the signal difference between the image signals of the first image data sets in at least one corresponding region of the first lung-representing image data set. The lung or the thorax volume is automatically determined using at least two of the first image data sets, or using at least an additional second lung-representing image data set in a breathing phase that corresponds with the breathing phase of a first image data set. The localized, quantitative ventilation of the lung is automatically calculated depending on the density change of the lung tissue and the change of the lung or thorax volume.
