//Fix for Ticket #623 - HH - It turns out that for memory usage optimization the pixel data tag is stripped from the in memory dataset.
//So while there are probably many better ways to address the missing pixel data tag a small hack was introduced because this entire utility will
//be completely refactored in the very near future to make use of the methods the pacs uses to parse the tags.
//Addendum to Comment above - HH 07/27/07 - Turns out that our implementation continues to remove the pixel data for optimization at this time so
//the workaround is still needed.
//Addendum to Comment above - JY 09/16/08 - Somewhere along the line, things were changed that made this line redundant - the only reference to
//it after this point is at +11 lines or so, and all it does is get file.Filename. Therefore, I am commenting this line out.
