FIGURE 2.
HYPR-LR processing of small-animal PET images of miniature Derenzo phantom. Transaxial slices of 1-min frames for FBP, HYPR-LR processing, and 3.78 × 3.78 × 3.63 mm (3 × 3 × 3 voxels) 3D boxcar smoothing of FBP image are displayed on top. Profiles (as shown on the images) plotting mean and SD of 1-min frames over entire 60-min study are shown on bottom. All images are shown using same window and threshold.
