Claim:
1. A method for determining a position-dependent attenuation map of at least one high frequency coil of a combined magnetic resonance positron emission tomography device (magnetic resonance PET device), wherein the high frequency coil includes at least one coil element, comprising: determining at least one first signal frequency for the at least one coil element during a magnetic resonance PET examination; determining at least one second signal frequency for the at least one coil element during the magnetic resonance PET examination, wherein at least one gradient field is applied during determination of the at least one second signal frequency; reconstructing a position of the at least one coil element using the at least one first signal frequency and the at least one second signal frequency; reconstructing a position of the at least one high frequency coil using the reconstructed position of the at least one coil element; and determining the position-dependent attenuation map of the at least one high frequency coil using the reconstructed position of the at least one high frequency coil.
