Abstract :
Two popular non-uniformity techniques were evaluated for the effect on tumor response measurements (change in tumor volume over time): a phantom correction method and homomorphic filtering. No improvement in tumor segmentation was achieved, and the tumor response measurement was less accurate when using a correction
