Configure Server Partitions |
|
For each server partition, some default behaviors can be set with regards to how DICOM devices connect to the partition. The partition can be configured to accept any device that connects to it, or to only allow connections from DICOM devices that have been configured for the partition. The server can also be configured to automatically insert DICOM devices into the device list when they connect. When automatic insertion is enabled, a default DICOM listen port can be configured that will be set for the device.
If no studies exist on a partition, the partition can be deleted. Note also that partitions can be disabled so that the Windows service no longer listens for DICOM connections to the partition.
The ImageServer also allows for configuration of a policy for each partition on how to handle duplicate images that the partition receives. The currently supported policies are the following:
| • | Send a failure response message for any duplicate C-STORE-RQ messages received. |
| • | Send success for any duplicate C-STORE-RQ messages received, and ignore the new message. |
| • | Examine any duplicate C-STORE-RQ messages received, and report any differences in the messages (if they exist) through the Study Integrity Queue. |
The server partition page is for configuration of partitions associated with the server. Each partition has an Application Entity (AE) title and port number associated with it. Each partition is in essence a virtual partition that shares resources with the other partitions. Server Partitions can be added, edited, deleted, or queried. Note that partitions can only be deleted when they don't have any studies stored on them. The search results on this page shows the current number of studies stored on each partition.
Partitions have a number of different options that can be set for them from the Add/Edit dialog:
General
The General Tab configures a number of general settings for the partition:
| • | AE Title: The DICOM Application Entity (AE) Title. AE Titles must be unique per partition. |
| • | Port: The TCP/IP listen port for the partition's DICOM server. The listen port can be shared with other partitions. |
| • | Description: A textual description of the partition used when logging and for display purposes. |
| • | Folder Name: The name of the folder where images are stored within a filesystem. The folder name must be unique per partition. Typically the Folder Name is the same value as the AE title. Note that if a folder name is edited, the physical folder on the filesystem must be manually renamed so that the ImageServer can still access its studies. |
| • | Enabled: The ImageServer service will automatically monitor when a partition is disabled and will stop listening for new incoming associations when the partition is disabled. |
| • | Duplicate Object Policy: Configures the policy used by the partition to handle duplicate images sent to the partition. The following policies are available: |
| o | Send Success (default): Send a success response to the client DICOM device, but ignore the duplicate image. |
| o | Reject Duplicates: Send a failure status to the DICOM client. |
| o | Compare Duplicates: Send a success status to the DICOM client and compare the duplicate image to the original image received. If there are differences, place a record in the Study Integrity Queue for processing. |
Remote Devices
The Remote Devices tab contains configuration options related to how remote DICOM devices are dealt with. The following summarizes the options:
| • | Accept Any Device: When selected, the partition will accept associations from any DICOM device. When not selected, the partition will reject DICOM associations that are not configured in the DICOM Device table. |
| • | Auto Insert Devices: When selected, devices are automatically inserted into the the DICOM Device table for the partition. |
| • | Default Remote Port: This option sets the port number that is inserted for a remote device when it is automatically inserted. This is set to port 104 as a default for the partition, but it can also be set to other common DICOM listen ports such as 4006 or 11112. |
Note: It is useful in some cases to start with a configuration where the partition automatically inserts DICOM devices into its device table. After all of the DICOM devices at a site are tested, it may make sense to change the configuration to only accept connections from configured DICOM devices. This makes it easier to initially configure the partition.
Study Matching
When images / SOP Instances arrive at the ImageServer for a study that has already been added, a comparison can be performed to see if the demographics of the new SOP Instances match the demographics entered into the database. The Study Matching tab configures which fields are checked for matches. The currently configured fields include: Patient Name, Patient ID, Patient Sex, Patient Birthdate, Accession Number, Issuer of Patient ID. In some cases, these checks may be problematic, and they can be disabled from this tab.
Delete Management
Specifies whether or not deleted studies will be tracked. If this option is enabled, deleted studies will appear in the deleted studies screen. When a delete is done from the Web GUI, the studies will be copied to a deleted folder and remain on the filesystem. Note that studies that are deleted due to disk management are not saved.
