Denoising of PET images by combining wavelets and curvelets for improved preservation of resolution and quantitation
An improved Positron Emission Tomography (PET) denoising methodology is proposed. The new method overcomes limitations of the PET state-of-the-art filters. The new filtering scheme is a combination of wavelet and curvelet transforms. A trade-off between denoising and structures integrity preservation is obtained.
