摘要：
A method for attenuation correction of a plurality of time-gated PET images of a moving structure includes establishing an ACF matrix, based on a baseline MR image of the structure developing a plurality of image transforms, each of the image transforms registering the baseline MR image to a respective cine MR image of the moving structure applying each of the image transforms to the ACF matrix to generate a corresponding cine ACF matrix time-correlating each of the cine MR images, and its corresponding cine ACF matrix, to one of the plurality of time-gated PET data sets and producing from each of the time-gated PET data sets an attenuation-corrected time-gated PET image.
