3 Introduction to the MiPACS Storage Server The Server Using LEADTOOLS Medical developer toolkits, Medicor Imaging has created the MiPACS Storage Server, a scalable and affordable image repository and management system for most DICOM-compliant modalities and client applications. The MiPACS Storage Server is an ideal starting point for any facility migrating towards a film-less environment. The MiPACS Storage Server is the backbone of a DICOM, (Digital Imaging and COmmunications in Medicine), network. MiPACS Storage Server Manager The DICOM 3.0 Standard: DICOM is an open standard that allows medical equipment and software from different manufacturers to communicate with one another and share medical data, improving patient care. DICOM is the most common standard for receiving medical images from a hospital, and is quickly becoming the standard for all types of medical communication. Devices, from MRIs and CT Scans to Printers and Software, are DICOM-compliant only if they strictly follow DICOM conformance. Conformance envelopes both a file format as well as a protocol for communication that DICOM-compliant devices must use. The advantage of keeping a clinic or hospital DICOM-compliant is that DICOM is an open, non-proprietary standard. A result of this is that any DICOM-compliant device can communicate with any DICOM server or printer, regardless of brand, type of device, or operating system. 1

4 Overview of Server Features Technical, Administrative, and Security Features Network Load Balanced/Failover Capability The MiPACS Storage Server can be configured in a Network Load Balancing Cluster to provide even distribution of traffic to more than one MiPACS Storage Server. Such a configuration, achieves failover capability as well. Upon failure of the Server service or physical failure of a server, other servers in the cluster pick up the slack. Runs as a service The MiPACS Storage Server runs as a service automatically in the background and requires no user interaction to start. If a server is restarted, there is no need to login. Logging of all DICOM, Server, and Error messages An extensive log can be kept of every event taking place on the MiPACS Storage Server. Every DICOM transaction, with clients identified, can be recorded. Database runs on SQL Server The MiPACS Storage Server database runs on a trusted and proven database server the Microsoft SQL Server. Secure Communications Supported The MiPACS Storage Server can be configured to communicate with other devices over a secure port, with the option to verify server and client certificates. DICOM Features Full Compliance with the DICOM 3.0 Standard The MiPACS Storage Server is fully compliant with the DICOM 3.0 medical standard, and a conformance statement is provided with the Server. IP and Subnet Mask or Hostname Verification Client AE (Application Entity) titles can be bound to an IP address and subnet mask or to a hostname. With verification, if another computer on your network tries to connect as the AE title of an authorized computer, it will not be permitted unless the exact IP address or hostname are verified on the server. Access Level Security per Client The MiPACS Storage Server controls which AE Titles can query, retrieve, and/or store to the server. Capable of Anonymous Connections Anonymous connections can query and store to the server without being specified in the clients table. Receives Images The MiPACS Storage Server stores any received image, in its entirety, in its internal data store. Also, the MiPACS Storage Server extracts the query information and stores the patient, study, series, and image data in its internal database. 2

5 Accepts Queries from Other Devices The MiPACS Storage Server responds to any query request, basing its decisions on the records stored in the database. Accepts Retrieve Requests from Other Devices The MiPACS Storage Server responds to C-MOVE commands in order to process retrieve requests of images for the requester by obtaining a reference from the database. The object is then obtained directly from the data store. Transmits Images The MiPACS Storage Server transmits images to other compatible devices as a Service Class User of C-Store service. TCP/IP Network Communication Support The MiPACS Storage Server supports the TCP/IP network Communication Support stack protocol, adhering to the DICOM 3.0 standard. Multiple Simultaneous Connections The MiPACS Storage Server spawns a new process for each connection request it receives. Asynchronous Nature The MiPACS Storage Server allows only a single outstanding operation on an association. Therefore, the MiPACS Storage Server does not perform asynchronous operations, other than the default specified by the DICOM 3.0 standard. Image Forwarding Series can be forwarded manually or on a recurring schedule to other DICOM Servers. For example, a satellite clinic can forward exams to a central server at a different location on a daily or weekly basis for archiving. Image Cleanup Images can be cleaned up from a server manually or on a recurring schedule based upon the age of the exam, if they have been forwarded to a central DICOM server for archiving. For example, a satellite clinic can conserve storage space by deleting all images over 2 months old if they have already been forwarded to a central server for archiving. Autocopy The auto copy feature allows the storage server to be configured to automatically route moved DICOM image data to any number of PACS servers. This feature can be set up so that when the server receives a C-MOVE request to a destination AE it will automatically store it to some other server as well. When the storage server to connects to the remote PACS servers, it can be configured to optionally use a custom AE title. For performance, the auto copy processing can be performed in a user-specified number of different threads Gateway The gateway feature allows DICOM servers to be created that act as a proxy to communicate with other DICOM servers on the client s behalf. This allows clients to send query/retrieve requests only to the gateway server. Those requests can then be automatically relayed to any number of other PACS servers. The Gateway can forward C-FIND and C-MOVE DICOM messages. Requests are forwarded to the specified remote DICOM servers and the responses forwarded back from the gateway to the requested clients. Images moved from remote servers are stored in the local main storage server database. Multiple remote servers can specified for each gateway. If one remote server fails to respond, then the next remote server in the list is used, continuing until a server responds before sending a failure message to the requested client. 3

6 System Requirements The requirements of the MiPACS Storage Server depend on the number of clients connecting to it and the amount of traffic those clients generate. In addition, the amount of storage required depends on the number of patients seen. Examples of recommended configurations are shown below. The MiPACS Storage Server is designed for 32-bit or 64-bit* operating systems running Microsoft Microsoft Windows 2000 Server, Microsoft Windows Server 2003 or Microsoft Windows Server To utilize Network Load Balancing, Microsoft Windows Server 2003 or 2008 is required. MiPACS Storage Server Example Configurations Configuration 1 - SQL Redundancy / MiPACS Workload Distribution / Maximum Scalability: Two PE R410 Servers run MiPACS Storage Server in a load-balanced configuration. In addition, two other PE R410 Servers run SQL Server in an active/passive configuration and are connected via iscsi or Fibre-channel to shared storage on a Dell Storage Array. The Storage is used by the MiPACS image store and can be placed active on whichever node SQL is not currently active. Microsoft Windows Server 2003 or 2008 Enterprise Edition is required for clustering.

7 Cons Storage Array is expensive Enterprise licenses for OS are expensive Required manual intervention if load-balanced hardware fails Configuration 2 - MiPACS Redundancy / SQL Redundancy: Two PE R410 Servers are connected via iscsi or Fibre-channel to shared storage on a Dell Storage Array. MiPACS and SQL are both configured as cluster resources in different cluster groups. MiPACS remains active on one node, while SQL is active on the other. If at any point a node fails, its function can be moved to the other node. Database storage and image storage are located on the Storage Array. Microsoft Windows Server 2003 or 2008 Enterprise Edition is required for clustering. Dell PowerVault MD3220 Dual SAS Controllers 8 300GB SAS Hard Drives (2.1TB Storage) Redundant power supplies Drives are expandable to 24 for 6.9TB total storage when more storage is needed later 2 Dell PowerEdge R410 Servers (running both SQL and MiPACS Storage Server) Quad Core Xeon Processors 4 GB RAM 2 Mirrored SATA hard drives (for OS and Software installations) Fibre-channel or iscsi host bus adapter card Windows Server 2003/2008 Enterprise SQL Server 2005/2008 Standard or Enterprise Pros Redundant hard drives in each machine Redundancy in both server applications (SQL and MiPACS) Redundant storage (RAID5) Fast access to images Scalability Storage Array can be scaled to 6.9TB Workload distribution (SQL on one server and MiPACS on the other) Cons Storage Array is expensive Enterprise licenses for OS are expensive Configuration 3 - MiPACS Workload Distribution / No SQL Redundancy / Maximum Scalability: Two PE R410 Servers run MiPACS Storage Server load-balanced and one PE R710 serves as an image storage and SQL server. 2 Dell PowerEdge R410 Servers (running MiPACS Storage Server) Quad Core Xeon Processor 4 GB RAM 2 Mirrored hard drives (for OS and Software installations) Windows Server 2003 Standard 5

12 MiPACS Storage Server Operating Procedures The Server Directory Layout and Notes about the Application: Note that the MiPACS Storage Server saves the DICOM images separately from the database. Images are stored to a physical drive and the references to the DICOM images are stored in a SQL database. By default the MiPACS Storage Server creates a database (MiPACS_DB.mdf ) and a transaction log file (MiPACS_DB_LOG.LDF) in the SQL server s default database directory (C:\Program Files\Microsoft SQL Server\MSSQL\Data). You can copy the database and map the image folder in the MiPACS Storage Server to a more suitable location on the network where more disk space is available for storing DICOM images. This also makes it easier for a database administrator to manage and back up the data. For example, you can do the following: Create a Directory for storing the images and database (e.g. S:\Medicor Imaging ). Create two sub-directories, named Images and Database. (e.g. S:\Medicor Imaging\Images, S:\Medicor Imaging\DataBase ). For more information, see the section on Configuring the MiPACS Storage Server using the Control Panel. 10

In most cases leave these options turned off. 37

40 Update Existing Patient check box If the image with the duplicate identifier has different patient information (name, DOB, PID, Sex), turning this option on will allow the server to overwrite the existing information for all of the existing images for that patient in the database tables. The DICOM tags will be left unaffected. Update Existing Study check box f the image with the duplicate identifier has different study information (study type, date), turning this option on will allow the server to overwrite the existing information for this study in the database tables. The DICOM tags will be left unaffected. Update Existing Series check box If the image with the duplicate identifier has different series information (series date, series type), turning this option on will allow the server to overwrite the existing information for that series in the database tables. The DICOM tags will be left unaffected. Update Existing Instance check box If the image with the duplicate identifier has different instance information (instance date, instance type), turning this option on will allow the server to overwrite the existing information for that instance in the database tables. The DICOM tags will be left unaffected. Auto Truncate Data check box Automatically truncates any stored data to the maximum defined length by the DICOM specification. Note that enabling this option affects storage performance, so it should be used only if necessary. 38

41 Query Settings page The Query Settings page displays settings that determine how a dataset is validated and what to include in a response dataset. Query Settings Page The following fields are on the Query Settings page: Request Dataset Validation group This group of fields are used when validating incoming C-Find requests. These options allow you to be less restrictive than what is specified in the DICOM specification about incoming C-Find requests. Each option is described below.
