orthanc-cli

orthanc-cli is a command-line interface for Orthanc, an open-source, lightweight DICOM server.

Compatibility

orthanc-cli usually supports the same Orthanc versions as its underlying orthanc-rs crate. See Compatibility for details.

Installation

There are multuple different ways to install orthanc-cli.

  • using cargo:

    $ cargo install orthanc-cli
    
  • manually downloading a release package from Github Releases page

Configuration

orthanc-cli needs several settings configured in order to communicate with an Orthanc server: Orthanc server address, and username and password (in case the server requires authentication).

Orthanc server address

Orthanc server address can be set with -s/--server command-line option. The value of the option is an HTTP(S) URL, e.g. http://127.0.0.1:8042. Alternatively, if you prefer to not type the option every time you call a command, you can set an environment variable ORC_ORTHANC_SERVER

$ export ORC_ORTHANC_SERVER=http://127.0.0.1:8042

Orthanc server authentication

If the Orthanc server you are working with requires authentication, you can provide it with command-line options -u/--username and -p/--password. Similar to the server address these can also be set as environment variables ORC_ORTHANC_USERNAME and ORC_ORTHANC_PASSWORD:

$ export ORC_ORTHANC_USERNAME=orthanc
$ export ORC_ORTHANC_PASSWORD=orthanc

Usage

Help

To get a general idea of the usage run orthanc --help. This will present the list of options, flags, and subcommands:

$ orthanc --help

Command-line interface for Orthanc, an open-source, lightweight DICOM server

USAGE:
    orthanc [OPTIONS] <SUBCOMMAND>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

Subcommands might have nested subcommands, which also respond to --help. If unsure, append --help to the command to see how to use it.

Entities and their IDs

orthanc-cli makes a convention of calling Patients, Studies, Series and Instances Entities (not to be confused with Application Entities). You might come across this naming in documentation or names of command-line options or flags.

Similarly to Orthanc web interface orthanc-cli operates mainly with unique identifiers (IDs) when it comes to referring to Entities (Patients, Studies, Series etc.). Each Entity is assigned a unique identifier (ID) by the Orthanc server, that looks similar to this:

22c54cb6-28302a69-3ff454a3-676b98f4-b84cd80a

In the list of Studies for example the identifiers are in the first column (ID):

$ orthanc study list
 ID                                             PatientID   AccessionNumber   StudyInstanceUID              StudyDescription   StudyDate   StudyTime   Number of Series

When you need to refer to an Entity in any of the orthanc-cli commands use its Orthanc ID:

$ orthanc study show cbec5098-53cd29f5-86d01e4b-c6e76386-709f00a6
 ID                 cbec5098-53cd29f5-86d01e4b-c6e76386-709f00a6
 Patient ID         8be8a583-193f48d2-d9b8dd53-adc11459-e46c7c27
 PatientID          patient_1
 StudyID            402411870

Anonymizing and modifying Entities

orthanc-cli allows modification and anonymization of Entities. Anonymization allows, and modification requires, the use of a configuration file describing how exactly the entity should be anonymized or modified. The format of the configuration file is explained in the next sections.

Note that both anonymization and modification create a copy of the entity that is being anonymized/modified instead of changing the entity in-place.

Anonymization

Anonymization of an entity can be done with or without configuration. If done without configuration, anonymization deletes or erases DICOM tags according to Application Level Confidentiality Profile Attributes:

$ orthanc study anonymize cbec5098-53cd29f5-86d01e4b-c6e76386-709f00a6
 New study ID   bb8802bf-fa9621bd-e43406cf-707a3cfb-7786ec34
 Patient ID     6cf95a77-4112b9d3-905c17f0-d48ee8e1-b9e6d482

The configuration file must be in YAML format and may contain the following fields:

  • replace - the values of specified DICOM tags will be replaced with those specified
  • keep - the values of the specified DICOM tags will be left intact even if they are specified as to be removed in the table mentioned above
  • keep_private_tags - whether or not to keep the values of private DICOM tags (defaults to false if omitted)

Example:

replace:
  PatientName: Rick Sanchez
  PatientBirthDate: 19700101
keep:
  - StudyDate
  - StudyTime
keep_private_tags: true

The usage of such a configuration file is as follows:

$ orthanc study anonymize cbec5098-53cd29f5-86d01e4b-c6e76386-709f00a6 -c /tmp/anonymization_conf.yml
 New study ID   22fc5ba2-650a6ef5-76f78251-af82a47f-87ce33f4
 Patient ID     8d8454ca-3c70d505-3d4ddced-792feac4-7c992741

Modification

A configuration file is required for modification. The configuration file must be in YAML format and may contain the following fields:

  • replace - the values of specified DICOM tags will be replaced with those specified
  • remove - the specified DICOM tags will be removed

Example:

replace:
  PatientName: Rick Sanchez
  PatientBirthDate: 19700101
remove:
  - StudyDate
  - StudyTime

The usage of such a configuration file is as follows:

$ orthanc study modify cbec5098-53cd29f5-86d01e4b-c6e76386-709f00a6 -c /tmp/modification_conf.yml
 New study ID   db0a9bc8-7b0362ca-f361c32b-ba62bfd2-44ff849b
 Patient ID     8be8a583-193f48d2-d9b8dd53-adc11459-e46c7c27
