  • Method for determining a position-dependent attenuation map of surface coils of a magnetic resonance/PET apparatus
    Patent number: 9541622
    Abstract: A method is disclosed for determining a position-dependent attenuation map of at least one surface coil of a combined magnetic resonance/PET apparatus. In an embodiment, the method includes acquiring magnetic resonance image data by way of the at least one surface coil during a magnetic resonance/PET examination of a patient; reconstructing the position of the at least one surface coil on the basis of the acquired magnetic resonance image data; and determining the position-dependent attenuation map of the at least one surface coil on the basis of the reconstructed position of the at least one surface coil. A magnetic resonance/PET apparatus and a computer program product, embodied to perform the method, are also disclosed.
