A general approach for partial volume correction of positron emission tomography (PET) images is introduced. The method is based on the merging of functional information from PET images and anatomical information using high resolution anatomical images. In order to decompose the PET and high resolution images the "à trous" algorithm was implemented. Results obtained with simulated and real patients images show a significant partial volume reduction and image enhancement. The relative errors in the partial volume corrected image are always less than 3,6% with respect to 16% of the original image.
