Hi Fatameh, please keep the posts on the list.
Private companies will probably not give you access to their own quality assurance documentation. However, that is not something I could decide. You need to specify what exactly you mean with accuracy before we can give a sensible answer. And even if you do, you will probably not be able to cite a post on a mailing list as literature for the purpose of your dissertation.

Is it possible to have access to such texts ? The size of a voxel is the accuracy ?
