Dear Dennis,

Thank you for sharing. I think they'll be useful, especially the first article which is more relevant to my work in Medical imaging / Radiography. However, I cannot access the full text but I'll get help from the library to do that. The second I managed to get the full text and there are valuable tips that I can adopt / adapt for my work.

Thank you again for your inputs.
