Simulated brainweb PET/MR data sets for denoising and deblurring

The data set consists of 20 subjects based on the normal anatomical models from the brainweb phantom. See https://brainweb.bic.mni.mcgill.ca/.

For each subjectXX the data is organized as follows:

1. image_0.nii.gz -> (1st simulated "random" PET contrast)
2. image_1.nii.gz -> (2nd simulated "random" PET contrast)
3. image_2.nii.gz -> (3rd simulated "random" PET contrast)
4. attenuation_image.nii.gz -> (attenuation image)
5. t1.nii.gz -> (high resolution T1 MR)

All data sets have a shape of (220,220,184) and a voxel size of 1mm x 1mm x 1mm and are provided in nifti format.
The T1 MR scans and antomical models used to create the ground truth PET images are taken from the BrainWeb: Simulated Brain Database.
