Width of the minimum bounding box of each lesion in the head-foot direction, as a box plot. Note that widths are quoted as a percentage of the corresponding motionless lesion value. Labels correspond to: (UC) Uncorrected PET, (IC) Our proposed indirect correspondence technique, (DC) The direct correspondence technique, and (PT) Direct PET-PET registration. Note that for IC and DC in the All Lesions graph and DC in the Lung Lesions graph, the median corresponds to the lower quartile
