The DICOM Archive module provides a front end to view the metadata
about DICOM studies and series that have been registered in the
LORIS database via the first step of the imaging pipeline (using
dicomTar.pl). Protocol checks and QC are performed later on and not
represented in this module.
The DICOM Archive is primarily used by DCC staff who are investigating the status of imaging pipeline scripts.
The DICOM Archive shows DICOM tar metadata. It does not provide a
way to visualize scans or view metadata of other data formats. It
provides a frontend to the tarchive_* tables in LORIS, but does
not directly inspect files on the filesystem. However, DICOM
files can be downloaded through the frontend and inspected on a
user's system.
The permission dicom_archive_view_allsites is required to access
the DICOM Archive module.
The patientNameRegex, LegoPhantomRegex, and LivingPhantomRegex
configuration variables provide regular expressions to ensure that
the DICOM has been properly anonymized. If at least one of these
isn't matched, the Patient Name is displayed as "INVALID - HIDDEN".
By default, when the regex is blank (such as in a default LORIS
install), all patient names are shown.
The patientIDRegex configuration has a similar purpose for the
Patient ID column.
The showTransferStatus configuration option is obsolete and should
not be used, but determines if a first "Transfer Status" column
appears in the menu table.
For downloading large DICOM files, it may be necessary to increase the
value of the memory_limit configuration option within php.ini.
The tarchive tables used by the DICOM archive must be populated by
the imaging dicomTar.pl script before there is any data in the module.
The menu for the DICOM Archive module links to the imaging browser
module, for scans which have been successfully inserted. Clicking on this link
will download a copy of the DICOM tar file. Note that the PatientName field is
prepended to the downloaded file though it is not stored this way on the server.
