Device and method for determining a heating effect of a magnetic resonance imaging sequence on a diagnostic modality

A method for determining a heating effect of an imaging sequence of a second imaging modality on a detector of a first modality of a combined imaging device in dependence of a reference imaging sequence of the second imaging modality, the first modality being configured to acquire diagnostic data of an examination object, the second imaging modality including a magnetic resonance imaging device configured to acquire magnetic resonance imaging data of the examination object, and the first modality including a temperature compensation unit configured to compensate a temperature variation of the detector, the method comprising:

• performing a reference imaging sequence using the second imaging modality, the reference imaging sequence including applying at least one of a gradient magnetic field and a high frequency electromagnetic field to the image acquisition region of the combined imaging device, and the reference imaging sequence including a plurality of imaging parameters determining a property of the at least one of the gradient magnetic field and the high frequency electromagnetic field;
• acquiring at least one temperature dependent parameter of the detector of the first modality;
• and
• determining a heating effect on the detector of the first modality in dependence of the plurality of imaging parameters of the reference imaging sequence and the at least one temperature dependent parameter of the detector.
