MR-based MC in a Hoffman phantom using MPRAGE-derived motion estimates: MR images in the reference position (top row), uncorrected PET images (second row), data corrected in the LOR space before image reconstruction (third row) and in the image space after reconstructing each individual frame (forth row). Note the substantial improvement in image quality after MC. Images in the transaxial, coronal and sagittal orientations are shown in each case.
