    • The invention relates to an upper body MRI scanner comprising a magnet arrangement for producing a horizontally oriented homogeneous main magnetic field, said magnet arrangement being designed to examine the upper body of a standing patient. An image acquisition unit is provided for continuously creating upper body image of the standing patient. A quality checking unit is designed for automatically determining a quality metric characterizing the quality of the upper body images. An imaging controller connected to the image acquisition unit and the quality checking unit is provided for activating the image acquisition unit and outputting signals for influencing the position and/or behavior of the patient as a function of the characteristic quality metric. An output unit connected to the image acquisition unit is used for displaying and/or storing at least some of the upper body images.

    • In a method for automated evaluation of a three-dimensional map of a laterally-symmetric organ system as well as medical image acquisition system and a computer program for this purpose, a three-dimensional image of the organ system is segmented, and the segmented organ system is deformed such that the deformed organ system has two mirror-symmetric halves with regard to its external shape. The differences between both mirror-symmetrical halves of the deformed organ system are determined by a comparison of one half with the other half. Alternatively, instead of the deformation of the segmented organ system a mirror-symmetric normal model of the organ system can be deformed, relative to the organ system, or vice versa, such that differences of corresponding regions of both halves of the organ system can be determined using the normal model. The determined differences are presented to a user.

    • A positron emission tomography unit (PET), having a unit part assigned to an examination space and a first evaluation unit, is combined with a magnetic resonance tomography unit (MRT). The unit part of the PRT includes at least two gamma ray detector units with in each case an assigned electronics unit. The MRT includes a second evaluation unit, a gradient coil system and a high frequency antenna device formed as a stripline antenna device having at least two conductors. The high frequency antenna device is arranged nearer to the examination space than the gradient coil system with a high frequency shield between the gradient coil system and the high frequency antenna device. Each conductor of the stripline antenna device respectively includes a gamma ray detector unit with an assigned electronics unit. The conductors of the stripline antenna device are configured for the respective gamma ray detector units and their assigned electronics units as shielding covers that are caused by the high frequency antenna device and are opaque to high frequency radiation. An examination object in the examination space can be imaged by the combined positron emission tomography and magnetic resonance tomography unit.
