901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	12 An "Orthanc peer" is another instance of Orthanc, possibly running on
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	13 a remote computer.
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	14
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	15 Contrarily to a "modality", it is possible to communicate with a peer
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	16 through the HTTP/HTTPS protocol (i.e. through the REST API of
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	17 Orthanc), and not through the DICOM protocol. This implies a much
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	18 easier configuration: It is only required to know the URL, the
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	19 username and the password to communicate with an Orthanc peer. This
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	20 contrasts with DICOM query/retrieve, that is quite complex and that
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	21 involves a lot of pitfalls (cf. the FAQ entry about :ref:`troubleshooting
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	22 DICOM communications <dicom>`) that can be bypassed if using HTTP.
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	23
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	24 Furthermore, as HTTP(S) communications are generally not blocked by
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	25 firewalls (contrarily to the DICOM protocol that is inherently an
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	26 Intranet protocol and that often requires the setup of VPN tunnels),
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	27 it is much easier to setup communications of medical images through
218 8bb11cd0f20f links amazy parents: 170 diff changeset	28 the Internet with :ref:`Orthanc peers <peering>`.

901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	35
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	36 Because of its focus on low-end computers, Orthanc implements **disk
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	37 space recycling**: The patient that has been stored for the longest
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	38 time inside Orthanc can be automatically deleted when the disk space
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	39 used by Orthanc grows above a threshold, or when the number of stored
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	40 patients grows above a threshold. This feature enables the automated
278 9bf644571511 fix doc wrt recycling order amazy parents: 224 diff changeset	41 control of the disk space dedicated to Orthanc. Note that each time
9bf644571511 fix doc wrt recycling order amazy parents: 224 diff changeset	42 a new instance is received for an existing patient, the patient will
9bf644571511 fix doc wrt recycling order amazy parents: 224 diff changeset	43 be marked as the most recent one in the recycling order.

901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	45 Recycling is controlled by the ``MaximumStorageSize`` and the
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	46 ``MaximumPatientCount`` options in the :ref:`Orthanc configuration
106 7063afe5748c added info about recycling amazy parents: 95 diff changeset	47 file <configuration>`. Setting both these values to 0 will disable

901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	50 It is possible to prevent important data from being automatically
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	51 recycled. This mechanism is called protection. Each patient can be
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	52 individually protected against recycling by using the
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	53 ``Unprotected/Protected`` switch that is available from Orthanc
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	54 Explorer.
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	55
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	56 Note that protection is only available at the patient level. It
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	57 protects all the studies/series/instances of the patient against
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	58 recycling. The rationale is that we think it is important to keep
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	59 available all the data related to one patient. Unwillingly losing a
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	60 study/series that is part of the same patient might lead to a loss in
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	61 consistency with respect to the medical history of this patient.
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	62
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	63 .. _compression:
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	64
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	65 Compression
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	66 -----------
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	67
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	68 If your disk space is limited, besides :ref:`recycling`, you should
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	69 also consider using disk space compression. When compression is
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	70 enabled, Orthanc compresses the incoming DICOM instances on-the-fly
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	71 before writing them to the filesystem, using `zlib
25 669ea65ba7fb fix links Sebastien Jodogne <s.jodogne@gmail.com> parents: 0 diff changeset	72 <https://en.wikipedia.org/wiki/Zlib>`_. This is useful, because the
0 901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	73 images are often stored as raw, uncompressed arrays in DICOM
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	74 instances: The size of a typical DICOM instance can hopefully be
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	75 divided by a factor 2 through lossless compression. This compression
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	76 process is transparent to the user, as Orthanc automatically
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	77 decompresses the file before sending it back to the external world.
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	78
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	79 Compression is controlled by the ``StorageCompression`` option in the
901e8961f46e initial commit Sebastien Jodogne <s.jodogne@gmail.com> parents: diff changeset	80 :ref:`Orthanc configuration file <configuration>`.

d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	88 Metadata consists in an associative key-value array (mapping a
d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	89 integer key in the range [0,65535] to a string value) that is
d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	90 associated with each :ref:`DICOM resource <orthanc-ids>` stored inside
d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	91 Orthanc (may it be a patient, a study, a series or a DICOM
d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	92 instance). Metadata can be either referred to using the integer key,
d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	93 or using a symbolic name (if configured). Metadata records
d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	94 information that is not readily available in the DICOM tags.

d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	96 In spirit, the metadata mechanism is similar to the :ref:`attachment
d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	97 mechanism <orthanc-storage>`. However, metadata is stored directly
d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	98 inside the database, whereas attachments are stored as separate files
d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	99 on the filesystem (the database only stores a reference to the
632 38face2a84a4 metadata are utf-8 strings Sebastien Jodogne <s.jodogne@gmail.com> parents: 622 diff changeset	100 attachments). Choosing between metadata and attachments is most often
38face2a84a4 metadata are utf-8 strings Sebastien Jodogne <s.jodogne@gmail.com> parents: 622 diff changeset	101 a matter of trade-off: Metadata must be kept small (as a rule of
38face2a84a4 metadata are utf-8 strings Sebastien Jodogne <s.jodogne@gmail.com> parents: 622 diff changeset	102 thumb, under 1KB) and used if fast access is needed, whereas
38face2a84a4 metadata are utf-8 strings Sebastien Jodogne <s.jodogne@gmail.com> parents: 622 diff changeset	103 attachments can be used to store arbitrarily large piece of data.

38face2a84a4 metadata are utf-8 strings Sebastien Jodogne <s.jodogne@gmail.com> parents: 622 diff changeset	105 However, pay attention to the fact that metadata must be UTF-8 strings
38face2a84a4 metadata are utf-8 strings Sebastien Jodogne <s.jodogne@gmail.com> parents: 622 diff changeset	106 terminated by the ``\0`` character. If you need to store arbitrary

36bf58dfb7f7 added core metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 660 diff changeset	126 DICOM instance to Orthanc using the DICOM protocol.
78 d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	127 * ``ModifiedFrom`` and ``AnonymizedFrom`` hold from which original
d6bd1dd820e5 metadata Sebastien Jodogne <s.jodogne@gmail.com> parents: 25 diff changeset	128 resource, a resource was modified or anonymized. The presence of

8bda16db46cf SynchronousCMove: Synchronous vs. asynchronous C-MOVE SCP Sebastien Jodogne <s.jodogne@gmail.com> parents: 661 diff changeset	450 Orthanc will queue the C-MOVE instructions and :ref:`creates a job

8bda16db46cf SynchronousCMove: Synchronous vs. asynchronous C-MOVE SCP Sebastien Jodogne <s.jodogne@gmail.com> parents: 661 diff changeset	453 PACS systems, but requires the client software to be more complex as

8bda16db46cf SynchronousCMove: Synchronous vs. asynchronous C-MOVE SCP Sebastien Jodogne <s.jodogne@gmail.com> parents: 661 diff changeset	457 As a consequence, by setting ``SynchronousCMove`` to ``true``, Orthanc
8bda16db46cf SynchronousCMove: Synchronous vs. asynchronous C-MOVE SCP Sebastien Jodogne <s.jodogne@gmail.com> parents: 661 diff changeset	458 can be used as a buffer that enables communications between a simple
