To improve the high noise problem for a PET image is important work because the quality of the PET image and the diagnosis accuracy is affected by this noise. For this reason, a novel subband denoising technique is provided. The method is based on subband transformation and a statistical method. By using the technique the noise can be inhibited effectively.
