Figure 9

An example of the subtraction of PET and CT feature image sequences. (a), (b), and (c) represent the subtraction before registration and (d), (e), and (f) represent the subtraction after registration. (a) and (d) are along the transverse plane, (b) and (e) are along the sagittal plane, and (c) and (f) images are along the coronal plane.
