vbrename

From VoxBoWiki

vbrename takes a directory full of arbitrarily named DICOM files and sorts them into subdirectories based on various pieces of header information. It also renames the individual files, using timestamps where possible to make sure the lexical order is also the order of acquisition. vbrename does not modify the contents of the files. Here's the help text:
