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

Figure 6

Reconstructed images of the Derenzo phantom. Images in the first, second, and third rows are reconstructed with rotation increments and rotation 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.
