Perhaps I did not actually have to rename the images; however, when I used to3d, the dimon process, or medcon with the images not renamed it took the slices out of order and our images looked jumbled because you might have images from higher or lower interspersed incorrectly because of how it was reading the names of the files. I did not know another way to handle the naming to ensure that the slices show up in the correct order.
The raw image files came off of the scanner named like this:
MR.1.3.12.2.1107.5.2.32.35216.201210050737047783302523
MR.1.3.12.2.1107.5.2.32.35216.201210050737049913702524
I was used to handling data that was named like this so we wrote a script to rename everything:
003-00001-00000191.dcm
003-00001-00000192.dcm
