Hello Bailey4

I'm sorry. That's just like me, open mouth, insert foot. :rolleyes: I did not realize the difference until I looked at it and thought of myself. My initials are PTB.

I searched myself and found that much more information popped up when I typed in proton beam therapy, instead of PBT.
