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.
