Hi, could you tell me the meaning of image types??original??Pre-processed??Post-processed??what are the steps about pre-processed and post-processed?Thanks!
Original images are the raw unprocessed DICOMS. All pre- and post-processed images are derived from original DICOM images.
Pre-processed images (depending on scanner) have undergone a combination of the corrections outlined at the following link: http://adni.loni.usc.edu/methods/mri-analysis/mri-pre-processing/
Post-processed scans have undergone various other corrections.
To see the precise processing steps performed on pre-or post- processed scans, select an image description once you have performed a search. You will be directed to a page with information on the exact processing steps for that image.
