One
challenge of PET/MR imaging is the correction of photon attenuation caused by
hardware in the field-of-view. For the particular case of MR local coil
attenuation, a solution based on stored templates is provided by commercially
available clinical PET/MR systems. This solution, however, is limited to rigid
coils docked in a pre-defined position. A
more general method encompassing other coil types would be desirable to improve
the accuracy of PET images. The goal of the present study is to investigate the
accuracy of fast ZTE acquisitions for the correction of local coil attenuation.
