Part 18 of the DICOM standard details an interface to DICOM Objects using HTTP. WADO enables, for example, retrieving DICOM images as JPEG using an HTTP GET request.[/fusion_text][fusion_text] The importance and acceptance of WADO increased dramatically together with the internet revolution and increasing use of cloud services and PACS as a Service. As a result, WADO evolved to include many of the standard DICOM Network Protocol commands and is gradually taking over. The DICOM Network Protocol defined in Part 8 of the DICOM Standard (Network Communication Support for Message Exchange) is still dominant mainly for connecting Imaging Modalities while WADO and implementation specific services over http rules the Web Applications used for viewing the images and related data. [/fusion_text][fusion_text]The current version of the DICOM Standard extends WADO into two main parts: WADO-WS - A Web Service version that supports the IHE XDS Integration Profile WADO-RS - RESTful API using XML or JSON that gradually covers all aspects of networking addressed by the older DICOM Network Protocol and includes, retrieval, storage, search and workflow.

A DICOM Element may have multiple values. String values are separated by \ while the VM of binary values is determined by dividing the element length in bytes by the size of one value.

[fusion_text]Acronym for “Unique Identifier”. UID’s are widely used in DICOM and are assigned to objects, classes, transfer syntaxes, special services, and specific data elements. NEMA registers DICOM UID’s and every instance of a DICOM application should have a UID prefix that it can use to generate new UID’s from.[/fusion_text]

[fusion_text]Defines how data elements are serialized in three (3) aspects: (1) Byte order (Little/Big endian) (2) Explicit or Implicit Value Representation and (3) If and what type of compression is used for the image pixel data element. Represented as a pre-defined UID. Transfer syntax is negotiated for every service in the association setup phase and is also part of the file meta information header. [/fusion_text]

[fusion_text]Picture Archive and Communication System. It is commonly accepted that PACS provides its services using the DICOM Network Protocol. PACS is an information technology system that provides services for archiving and restoring medical imaging documents using the DICOM network protocol standard. A common PACS provides the following services: Storage - Allows imaging modalities to store the images they produce by sending C-STORE commands with DICOM Instances. Search - Allows searching for Patients, Studies, Series and Images by their attributes such for example Patient Name and ID, Study Date, and other DICOM Data Elements . The search is part of the DICOM Query/Retrieve Service and performed by sending the C-FIND command . Retrieve - Gets a copy of documents that are stored in the PACS in the form of DICOM Instances by sending a C-MOVE DICOM Command with the keys that identify the documents. The Retrieve is part of the DICOM Query/Retrieve Service and is performed by sending the C-MOVE command . PACS in IHE - Image Archive/Image Manager IHE defines the Image Archive/Image Manager actor. This role is usually played by the PACS. IHE technical framework details all the transactions that the PACS should support. These transactions include in addition to storage and query/retrieve, the Storage Commitment service (SCM) that is intended for transferring ownership of previously stored instances. [/fusion_text]

Q: SCM - Storage Commitment Management

[fusion_text] A DICOM Service that is used to “pass the ownership” on DICOM Instances from one application to another. It confirms that a DICOM Application stores a set of DICOM Instances in a similar way to the “commit” SQL command. When receiving successful commit result, an application can assume that the instances are safely stored by the other application and can delete them from its own storage. [/fusion_text]

Q: Service Object Pair (SOP) Class

[fusion_text]A pair of an IOD and DIMSE Service that together defines a capability of a DICOM AE. At association phase, AE’s exchange SOP Class UID’s and agree on their capabilities.[/fusion_text]

Q: MWL - Modality Worklist Management

[fusion_text] A DICOM Service that is used for managing “tasks” for Imaging Modalities. [/fusion_text]
