FIGURE 3.
HYPR-LR processing of images of multiradionuclide phantom. Cylindric volume is filled with 11C (t1/2, 20.4 min), and surrounding volume contains 18F (t1/2, 110 min). Total summed image (0–40 min) and FBP-reconstructed images of 1-min frames at 0, 20, and 40 min are shown on top. Blurred composite (sum) image and 1-min frames of data processed with HYPR-LR using 3.78 × 3.78 × 3.63 mm (3 × 3 × 3 voxels) 3D boxcar filter are shown on bottom. All images are scaled to maximum intensity of 37 kBq/mL.
