Wavelet Denoising in Voxel Based Parametric Estimation of Small Animal PET Images: A Systematic Evaluation of Spatial Constraints and Noise Reduction Algorithms
Voxel based estimation of PET images, generally referred to as parametric imaging, can provide invaluable information about the heterogeneity of an imaging agent in a given tissue. Due to high level of noise in dynamic images, however, the estimated parametric image is often noisy and unreliable. Se...
