6 1. Implementation Model The ONIS DICOM Client is a medical imaging application that receives objects (images) for storage but does not allow the query and retrieval of these objects. It runs on the following Microsoft Windows platform:. Windows XP Professional. Windows 2003 Server. Windows Vista 32 & 64 bits - Windows 2008 Server as a plugin for ONIS 2.0 that accepts association requests from external applications. ONIS DICOM Client can be started automatically when ONIS 2.0 starts up. Users can modify the different available settings of the ONIS DICOM Client from the preference panel of ONIS 2.0. The following parameters of the ONIS DICOM Client are configurable from the preference panel of ONIS 2.0: - Application Entity Title of the DICOM Server - Listening port number - Maximum number of clients which can be connected at same time - Time out settings (Idle, Connection, Move and Store) - PDU Size - Security options (verification of the called and calling AE title and/or IP Addresses). After modifying any of the above settings, the ONIS DICOM Client needs to be restarted in order for the changes to take effect. Through the Clients page of the preference panel of ONIS 2.0, the definition of the AE Applications that can connect to the DICOM Server can be defined. The following parameters can be defined for each AE Application: - Application Entity Title - IP Address - Port Number (when this AE Application will be used as an SCP) 6

11 The AE will accept any PDU length, offered on associations initiated by remote applications. However, the actual PDU size will not exceed the maximum size requested by the SCP. It is recommended that it does not exceed 64 Kbytes Number of Associations ONIS DICOM Client supports multiple associations in both SCP and SCU. The maximum number of associations opened simultaneously can be defined in the preference panel of ONIS 2.0. This number should not exceed Asynchronous Nature ONIS DICOM Client does not support negotiation of multiple outstanding transactions Implementation Identifying Information Implementation Class UID: Implementation Version Name: _Server Association Initiation Policy ONIS DICOM Client Initiates associations under the following conditions: - User invokes a CFIND request to a remote AE - User invokes a CMOVE request to a remote AE - User invokes a CGET request to a remote AE - User invokes Image Store to a remote AE CFIND requests sent to to remoted AE 11

If the transfer syntax of the SOP Instance to be transferred is not Implicit VR Little Endian, ONIS DICOM Client proposes two transfer syntax s: 17

18 1) Transfer syntax of the original SOP Instance 2) Implicit VR Little Endian ONIS DICOM Client always includes Implicit VR Little Endian as proposed transfer syntax for each abstract syntax. The proposed transfer syntax can be one of the following: Name UID Implicit VR Little Endian Explicit VR Little Endian Explicit VR Big Endian Baseline JPEG (Process 1) Extended JPEG (Process 2,4) Extended JPEG (Process 3,5) Spectral JPEG (NonHier, Process 6,8) Spectral JPEG (NonHier, Process 7,9) Full JPEG (NonHier, Process 10, 12) Full JPEG (NonHier, Process 11,13) Lossless JPEG (NonHier, Process 14) Lossless JPEG (NonHier Process 15) Extended JPEG (Hier, Process 16, 18) Extended JPEG (Hier, Process 17, 19) Spectral JPEG (Hier, Process 20, 22) Spectral JPEG (Hier, Process 21, 23) Full JPEG (Hier, Process 24, 26) Full JPEG (Hier, Process 25, 27) Lossless JPEG (Hier, Process 28) Lossless JPEG (Hier, Process 29) Lossless JPEG (NonHier, Process 14B) RLE Lossless Table

19 SOP Specific Conformance for Storage SOP Class ONIS DICOM Client Provides standard conformance to the DICOM Storage Service Class Association Acceptance Policy ONIS DICOM Client accepts associations initiated by a remote AE under the following conditions: - Association for Verification SOP Class is accepted, if SCU is defined in user defined list (see paragraph 5.2). - Association for Storage SOP Classes is accepted, if SCU is defined in user defined list (see paragraph 5.2) Verification requested by a remote AE Associated Real-World Activity Associated Real-World Activity is the verification of the DICOM communications.

21 Query/Retrieve SCU. ONIS Remote Client does not support any Query/Retrieve FIND service from a Remote AE Move Requested by a remote AE Associated Real-World Activity The associated Real-World Activity with the Query/Retrieve MOVE Service is to transfer images to a destination AE as requested by a DICOM Query/Retrieve MOVE SCU. ONIS DICOM Client does not support Query/Retrieve MOVE Service from a remote AE Get Requested by a remote AE Associated Real-World Activity The associated Real-World Activity with the Query/Retrieve GET Service is to transfer images to the SCU which has requested the GET SOP Service Class. ONIS DICOM Client does not support Query/Retrieve GET Service from a remote AE Storage requested by a remote AE Associated Real-World Activity The associated Real-World Activity with the Storage Service is the storage of image data on a local hard disk. Images are retained in DICOM Part 10 compliant file format, until user intentionally deletes them. ONIS DICOM Server is Level 2 SCP for all Storage SOP Classes. 21

24 Table SOP Specific Conformance for Storage SOP Class ONIS DICOM Client provides standard conformance to the DICOM Storage Service Class Presentation Context Acceptance Criterion Any of the Presentation Contexts shown in Table are acceptable for ONIS DICOM Client Transfer Syntax Selection Policies ONIS DICOM Client will use the first transfer syntax proposed by the remote AE in the presentation context. If the first transfer syntax is not available, then it will use the second one and so on. The remote AE must support at least Implicit VR Little Endian. 3 Communication Profiles 3.1 Supported Communication Stacks ONIS DICOM Client provides DICOM V3.0 TCP/IP Network Communication Support as defined in PS TCP/IP Stacks Physical Media Support 24

25 ONIS DICOM Client is indifferent to the physical medium over which TCP/IP excutes. The recommended medium is 1000Base-T Ethernet. 4 Extensions / Specializations / Privatizations Not Applicable. 5 Configuration 5.1 AE Title / Presentation Address Mapping See paragraph 5.2 for Local AE Title and Port ID Settings. Local IP Address is configured through Windows users interface. 5.2 Configurable Parameters The following parameters of the ONIS DICOM Client are configurable through the preference panel of ONIS 2.0: - Application Entity Title of the ONIS DICOM Server - Listening port number - Maximum number of clients which can be connected at same time - Time out settings (Idle, Connection, Move and Store) - CSTORE Overwrite behavior - Security flags (check of called and calling AE and/or IP Addresses) After modifying any of the above settings, the ONIS DICOM Client needs to be restarted in order for the changes to take effect. 25

26 Through the clients page of the preference panel of ONIS 2.0, the definition of the AE Applications which can connect to ONIS DICOM Client can be defined. The following parameters can be defined for each AE Application: - Application Entity Title - IP Address - Port Number (when this AE Application will be used as an SCP) - Rights (Find, Get, Move and Store rights) 6 Support for Extended Characters Sets For Japanese Language only: ONIS DICOM Client supports Japanese Character sets, ISO 2022 IR 13, ISO 2022 IR 14 and ISO 2022 IR 87, as extended character sets for all SOP classes and both SCU and SCP roles. 26
