(54)System and method for correcting attenuation in hybrid medical imaging


(57) A hybrid medical imaging system (10) comprises a nuclear medicine imaging subsystem (12) for capturing an image of a target region of a subject, a magnetic resonance imaging (MRI) subsystem (14) for capturing an MRI image of the target region based on at least one MRI parameter and processing structure (16) communicating with the subsystems. The processing structure processes the MRI image to estimate attenuation within the target region and uses the estimated attenuation to correct the image captured by the nuclear medicine imaging subsystem.
