findscu

DICOM-rs findscu

This is an implementation of the DICOM Find SCU (C-Find), which can be used to search for study and patient records in a DICOM archive.

This tool is part of the DICOM-rs project.

Usage

Note that this tool is not necessarily a drop-in replacement for findscu tools in other DICOM software projects. Run dicom-findscu --help for more details.

There are two exclusive ways to specify a DICOM query:

Using the multi-value -q option

Each value is a text of the form «field_name»=«field_value», where:

• field_name is either a standard DICOM tag (in the form (gggg,eeee) or gggg,eeee) or a tag keyword name such as PatientName.
• field_value is the respective value or pattern to match against the value of the specified DICOM attribute. It can be empty, which in that case the = may also be left out.

Basic usage includes searching for a study or patient by a certain attribute. Only patient level and study level queries are supported.

# query application entity STORAGE for a study with the accession number A123
dicom-findscu STORAGE@pacs.example.com:1045 --study -q AccessionNumber=A123

# query application entity PACS for patients born in 1990-12-25
dicom-findscu PACS@pacs.example.com:1045 --patient -q PatientBirthDate=19901225

# wild-card query: grab a list of all study instance UIDs
dicom-findscu PACS@pacs.example.com:1045 -S -q "StudyInstanceUID=*"

Passing a query object file

As an alternative to term queries, you can also provide a DICOM query object as a file. There are currently no tools in DICOM-rs to assist in the process of creating these objects, but one can convert DCMTK DICOM data dumps into compatible DICOM query objects.

# query is defined in file
dicom-findscu PACS@pacs.example.com:1045 --study query.dcm
