Figure 4

Three- and 4-dimensional positron emission tomography and computed tomography (PET/CT) images of the phantom. (A) Three-dimensional PET/CT image of the nonmoving phantom where the CT and PET images are fused together. Three different views (axial, sagittal, and coronal) across the tumor are shown. (B) Four-dimensional PET/CT image of the moving phantom (sinusoidal motion with 15.4 mm amplitude). The 4-dimensional PET image was reconstructed with phase-matched attenuation correction. Sagittal views of PET/CT fusion from 5 of 10 breathing phases are shown.
