Influence of Rotation Increments on Imaging Performance for a Rotatory Dual-Head PET System

Figure 9

Reconstructed images of the hot spot phantom. The first row is the reconstructed results of 90° increments. The second and the third row are the results of 60° increments based on the nearest interpolation and bilinear interpolation, respectively. The columns, from the left to right, show the images from 50 mm, 70 mm, and 100 mm, respectively.
