ATTENUATION CORRECTION OF PET IMAGE USING IMAGE DATA ACQUIRED WITH AN MRI SYSTEM

摘要

A method for correcting attenuation in a positron emission tomography (PET) image includes acquiring images of tissue using a magnetic resonance imaging (MRI) system. The images of tissue are acquired by the MRI system at substantially the same time that sinogram data are acquired from the PET scanner. An attenuation correction sinogram is produced from the MR images and employed to correct the acquired sinogram data. PET images are then reconstructed from the corrected sinogram data.
