Motion Freeze for Respiration Motion Correction in PET/CT: A Preliminary Investigation with Lung Cancer Patient Data

<table>The coronal views of the fused PET/CT images from (a) 3D, (b) 4D (best bin), (c) motion freeze technology for patient number 4. A lesion in the left upper lobe of the lung and artifacts around the right diaphragm were observed on the 3D HCT images, and (d) vertical image profiles drawn across the lesion on <svg
