Hi,
One of the characteristics of conquest is that it will rewrite a file already in the pacs even exact duplicates. .
A wishlist would be a feature to allow or disregard files rewritten when a duplicate of a study is sent.
. it could be a dicom.ini parameter. The server would check the sopuid then compare name, patient, id, age, sex, accession number, birthdate and possibly other parameters of the incoming file. if those are the same with stored file, the the incoming file is ignored leaving the original intact. A log is also written of the duplicate file. A more complex alternative is a duplicate file is save in a separate folder. Otherwise if the parameter is not set the old file is overwritten. The dicom.ini could state something like overwriteduplicate=1, allowing files to be rewritten, which is the present default. It may increase cpu usage but a lot faster than rewriting a whole study I guess.
One reason for this request is we get ntfs errors on chkdsk.
Deleting corrupt attribute record (186, $I30)
This is a known ntfs "bug" deficiency.
