The document assumes familiarity with the DICOM Standard as defined by ACR-NEMA. It should be interpreted in conjunction with the published standard. 2.3 Remarks The NTT Data Unified Clinical Archive is a product of NTT Data, Inc. The DICOM application will evolve in the future to meet user requirements and to incorporate new features and technologies. NTT Data plans to adapt its software to future versions of the DICOM standard. This may result in changes to the support of the communications features listed in this Conformance Statement. The user should ensure that other devices conform to the evolving standard. Failure to do so could result in the loss of function and/or connectivity. NTT Data reserves the right to make changes to its products or to discontinue its delivery. This Conformance Statement by itself does not guarantee successful interconnection. It is the responsibility of the user to carry out additional validation tests to ensure the functionality, performance, accuracy and stability of the transmitted image and patient data. NTT Data will make every effort to keep the NTT Data Unified Clinical Archive Product backwards compatible with previous versions of the product and continue to support retired DICOM capabilities where feasible. NTT Data participates in testing sponsored by Integrated Healthcare Enterprise (IHE) and the NTT Data Unified Clinical Archive Integration Statement can be found on our Website. 2.4 Definitions, Terms and Abbreviations Big Endian: A form of byte ordering where multiple byte binary values are encoded with the most significant byte encoded first; and the remaining bytes encoded in decreasing order of significance. NTT Data, Inc. DICOM Conformance Statement Page 11
Little Endian: A form of byte ordering where multiple byte binary values are encoded with the least significant byte encoded first; and the remaining bytes encoded in increasing order of significance. Pixel Data: Graphical data (e.g. images or overlays) of variable pixel-depth encoded in the Pixel Data Element. Standard Data Element: A Data Element defined in the DICOM Standard, and therefore listed in the DICOM Data Element Dictionary in PS 3.6. Private Data Element: Additional Data Element, defined by an implementer, to communicate information that is not contained in Standard Data Elements. Data Element Tag: A unique identifier for a Data Element composed of an ordered pair of numbers (a Group Number followed by an Element Number). Sometimes the word Tag is used to indicate a Data Element Tag. Transfer Syntax: A set of encoding rules that allow Application Entities to unambiguously negotiate the encoding techniques (e.g. Data Element structure, byte ordering, compression, etc.) they are able to support, thereby allowing these Application Entities to communicate. Unique Identifier: A string of characters that uniquely identifies a wide variety of items; guaranteeing uniqueness across multiple countries, sites, vendors and equipment. Security Profile: A set of mechanisms, such as encryption, user authentication, or digital signatures, used by an Application Entity to ensure confidentiality, integrity, and/or availability of exchanged DICOM data. Service Class User: The role played by a DICOM Application Entity which invokes operations and performs notifications on a specific Association. Service Class Provider: The role played by a DICOM Application Entity which performs operations and invokes notifications on a specific Association. Service Class: A collection of SOP Classes which are related in that they are described together to accomplish a single application. Service-Object Pair (SOP) Class: The union of a specific set of DIMSE Services and one related Information Object Definition (as specified by a Service Class Definition) which completely defines a precise context for communication. Service-Object (SOP) Instance: A concrete occurrence of an Information Object and a communication context. The word Instance is sometimes used to indicate an SOP Instance. This Conformance Statement sometimes uses the abbreviation IOD to indicate an SOP Instance. Presentation Context: A specific SOP Class and a list of Transfer Syntaxes supported by an Application Entity for that SOP Class.

The indexstore AE stores the IOD on its local RAID/SAN and adds an entry to its Database for each IOD. This Database is used by the indexquery AE. In the background, the NTT Data Unified Clinical Archive will forward IOD s to one of UCA remote Data Centers where they will be transferred to long term storage for near term retrieval by the indexquery AE. When the indexstore AE receives IOD s it can forward them to other Remote AE s based on configuration parameters using the indexpush AE or indexforward AE. The Remote AE can send Commitment Requests of those IOD s to the indexstore AE. The indexstore AE will wait for the IOD s to arrive at an UCA Data Center before it takes action on
the Commit request. The indexstore AE will then send the results of the Commit Request back to the requesting Remote AE. A Modality can send MPPS messages to the indexstore AE, which will forward the messages to an Order Filler. After IOD s have been received and entered into the Database, an AE can send a Query/Retrieve Request to the indexquery AE to examine these IOD s. If the AE requests retrieval of IOD s, the indexquery AE retrieves those IOD s, either locally or from a- UCA Data Center, and sends them to the specified Destination AE in the case of a C-MOVE-RQ or to the requesting AE in the case of a C-GET-RQ using its DICOM Service. The indexquery AE can be configured to send Modality Worklist Queries to a Modality Worklist Server. Any Remote AE can verify the operational readiness and capabilities of either the indexstore AE or the indexquery AE by using their DICOM Verification Services. 3.1.2 Functional Definitions of Application Entities The NTT Data Unified Clinical Archive has four Application Entities (AE s) which act as a Service Class Provider and User, a Commitment Provider, a Procedure Step SOP Class Provider and User, a Basic Worklist Management Service Class User and a Query/Retrieval Provider. 3.1.2.1 indexstore Application Entity The indexstore AE provides the, Commitment, Procedure Step SOP Class and Verification DICOM Services. 3.1.2.2 indexpush/indexforward Application Entity The indexpush/indexforward AE use Services to forward IOD s to Remote AE s (e.g. display stations and workstations) based on the configuration information. The indexpush AE does not guarantee delivery; whereas, the indexforward AE does guarantee delivery. 3.1.2.3 indexquery Application Entity The indexquery AE provides the Query/Retrieval, Basic Worklist Management and Verification DICOM Services to find Patients, Studies, Series and Instances in the NTT Data Unified Clinical Archive Database and forward the requested IOD s to a Destination AE or the requesting AE using the DICOM Service. 3.1.3 Sequence of Real World Activities A Commitment Request can be sent on the same Association as the Store Request or later on a separate association. The indexstore AE will not send a Response to a Commitment Request until the requested IOD s are sent to a UCA Data Center. This normally will occur within a few hours but could take an extended period of time depending on configuration. The N-EVENT-REPORT message will be sent back on a new association. A Modality Performed Procedure Step message can be sent on the same Association as a Store Request or on a separate Association. The indexstore AE will forward the MPPS message to an Order Filler. When the indexpush AE forwards IOD s to another Remote AE there is a configurable limit on the number of times it will try sending the IOD s. As a result, there is no guaranteed delivery of these forwarded IOD s. When the indexforward AE forwards IOD s to another Remote AE the delivery is guaranteed. The indexforward AE will periodically retry sending any IOD s until it succeeds. The option of whether to use the indexpush AE or the indexforward AE to forward IOD s is configurable by Destination AE. NTT Data, Inc. DICOM Conformance Statement Page 17
A Query/Retrieve Request cannot retrieve a Study until after it has been entered in the Database which occurs sometime after the Originating AE sends the study and the Association is released. The indexquery AE can send Modality Worklist queries to a Modality Worklist Server. A WADO Client can send a request through the isowado.php to the indexquery AE. The indexquery AE will acquire the requested IOD files and the isowado.php will return the requested objects to the WADO Client. 3.2 Application Entity Specifications 3.2.1 indexstore Application Entity Specification 3.2.1.1 SOP Classes The indexstore AE provides standard conformance to the DICOM V3.0 SOP Classes listed in Table 3.2.1-1 as an SCP.

The limit is based on the size of the NTT Data Unified Clinical Archive and how many Associations the indexquery AE has opened. This limit is typically 25 on a small NTT Data Unified Clinical Archive Configuration. The indexstore AE is limited to 5 pending Association Requests. Once an Association is negotiated and accepted it is no longer pending and not counted in this limit.

If it is unable to send the results to the Remote AE, it will periodically retry to initiate the Association. It will give up after 60 days (or some other limit as configured). 3.2.1.2.1.2 Proposed Presentation Contexts Table 3.2.1-7 Proposed Presentation Contexts for Commitment SOP Class Abstract Syntax Transfer Syntax Role Ext.

The results of a Commitment Request will always be sent on a separate Association and not on an Association initiated by a Commitment. The Media File Set ID attributes (0008,1150) and (0008,1155) are not supported. The Retrieve AE attribute (0008,0054) is not supported. See Section 3.2.1.4 (Association Acceptance Policy) for the remaining conformance issues.
If the indexstore AE is unable to connect to the Originating AE then the indexstore AE will periodically retry to connect to the Originating AE for up to 60 days (a configurable limit). If an error status is given in the N-EVENT-REPORT-RSP, this error will be logged and no attempt will be made to resend the transaction. This is usually caused by an expired Transaction UID. The only Failure Reason (0008,1197) ever given by the indexstore AE is 0112H (No Such Object Instance) which indicates the requested SOP Instance UID was not in the NTT Data Unified Clinical Archive Database and thus never successfully received by the indexstore AE. The recommended action is to resend the IOD with that SOP Instance UID. The indexstore AE does not verify that the SOP class corresponds to the SOP Instance UID (Failure Reason 0119H). A duplicate Transaction UID is reported when the N-ACTION-RQ is sent with an N-ACTION-RSP error status of 0210H (Duplicate Invocation) rather than as failure reason 0131H (Duplicate Transaction UID). 3.2.1.2.2 Forwarding is Specified for the Originating AE 3.2.1.2.2.1 Associated Real World Activity The indexstore AE will initiate an instance of the indexpush AE or indexforward AE to forward the IOD s received from the Originating AE to a Destination AE, as configured. The indexpush AE may be initiated with a retry option based on configuration parameters. If the retry option is present then the indexpush AE will repeatedly try to send the IOD s for the configured number of times (see Section 3.2.2 - indexpush Application Entity Specifications). If the indexforward AE instead of the indexpush AE is used for forwarding to the given Destination AE, then the indexforward AE will periodically retry sending any IOD until it succeeds, guaranteeing delivery. The IOD s forwarded may be for one or more studies but will be for only one patient. There is no guarantee that the IOD s represent a complete study or that they will be delivered in any particular order. 3.2.1.2.3 Forwarding Modality Performed Procedure Step (MPPS) Requests 3.2.1.2.3.1 Associated Real World Activity When the indexstore AE receives an MPPS Request it will attempt to forward the request to an Order Filler. If indexstore AE is unable to forward the MPPS Request, it will periodically retry to initiate the Association. It will give up after 15 days (or some other limit as configured). 3.2.1.2.3.2 Proposed Presentation Contexts Table 3.2.1-8 Proposed Presentation Contexts for MPPS SOP Class Abstract Syntax Transfer Syntax Role Ext.

Any other Presentation Contexts for the Verification SOP Class will be rejected. If more than one Presentation Context is accepted, the can choose which Presentation Context to use. The indexstore AE will give preference to JPEG Lossless over JPEG 2000 Lossless for a compressed Transfer Syntax and Explicit VR Little Endian over Implicit VR Little Endian for an uncompressed Transfer Syntax. 3.2.1.3.1.2.1 Conformance to Verification SOP Class (SCP) The Verification Service conforms to the DICOM V3.0 Standard. Table 3.2.1-10 Verification Response Status
Service Status Further Meaning Error Code Reason Success Success 0 The status in a C-ECHO-RSP is always 0 (success). 3.2.1.3.2 Remote AE sends an IOD Store Request 3.2.1.3.2.1 Associated Real World Activity A Remote AE () sends a DICOM Store Request (C-STORE-RQ) to the indexstore AE for one or more IOD s (e.g. SOP Instances). Usually all the IOD s sent in one Association are for a single study, but this is not a requirement. If the IOD is sent using an accepted encoding (e.g. JPEG Lossless, RLE, etc.) then the IOD will be stored unchanged using that encoding. If the IOD is sent uncompressed then it is compressed using JPEG-LS. The indexstore AE stores the object in a DICOM compatible file which is encapsulated in a non-dicom encryption layer along with non- DICOM MD5 signatures on a local RAID/SAN. A success is reported to the Remote AE if the IOD is successfully stored. The Remote AE can also send Commit Requests on the same Association. After the Remote AE has sent all the IOD s and released the connection, or after an IOD has arrived with a new Patient Name, then the received IOD s are added to the Database on the NTT Data Unified Clinical Archive. A duplicate policy is applied to any IOD which has an SOP Instance UID that already exists in the Database. A configuration parameter determines the duplicate policy and can be set the following ways: 1 If the IOD is a byte-for-byte exact copy of an existing IOD with the same SOP Instance UID then it is discarded. Otherwise the new IOD is added to the Database, replacing all previous IOD s that have the same SOP Instance UID. This is the default. 2 Keeps the first IOD received and discards any subsequent IOD s with the same SOP Instance UID. 3 The new IOD is added to the Database, replacing all previous IOD s that have the same SOP Instance UID. After the IOD s have been added to the Database, they are queued to be copied to a UCA Data Center. The IOD s are sent encrypted and in a manner which guarantees reliable and accurate delivery. This process is non-dicom and beyond the scope of this document. At a UCA Data Center, the IOD s are staged on a RAID/SAN before being copied to permanent storage for remote access by the indexquery AE. Two separate permanent copies of the IOD are made. All copies are encrypted. The NTT Data Unified Clinical Archive can be configured to indicate that any IOD received from a given Remote AE (by AE Title) is to be forwarded to one or more other Remote AE s. In this case the indexstore AE will schedule this delivery. See the Association Initiation section 3.2.1.3 for indexstore and the indexpush/indexforward AE section 3.2.2 for further details of this process. The NTT Data Unified Clinical Archive can also be configured to forward IOD s to other NTT Data Unified Clinical Archives at the same site or other sites. In this case the indexstore AE queues the IOD s for forwarding to these remote NTT Data Unified Clinical Archives. This forwarding process send IOD s in an encrypted format and in a manner which guarantees reliable and accurate delivery.
