Coregistration of perfusion CT and PET images on day 7: rabbit number 3 in the control group. (a) A contrast-enhanced CT image from the thirty-first frame (time point) of perfusion CT and noncontrast CT image from PET/CT acquisition were coregistered to the same locations. (b) PET and coregistered perfusion CT images were rigidly fused using in-house developed software and ROIs were manually delineated throughout the whole tumor at each axial image.
