Features

• Select DICOM routing and mapping rules based on public DICOM tags and/or association information such as day-of-week and/or time-of-day to facilitate institutional scheduling requirements.
• Correct various connectivity problems by defining filters which can add/delete/modify DICOM tags, as well as change their transfer syntax.
• Aggregate a study from multiple inbound associations into a single outbound association, providing advanced DICOM router functionality.
• Route a single DICOM store job from one SCU to multiple SCPs.
• User defined filters may be added to any association, providing the ability to modify or map certain fields before forwarding, thus allowing the user to correct various connectivity problems.
• Schedule outbound jobs to be run during a specific time-of-day and/or day-of-week.
• Temporarily queue up outbound jobs to a particular destination while the destination is undergoing maintenance.
• Ability to alter the encoding (transfer syntax) of sop instances as they pass from one system to another, e.g., a modality stores images to Compass as implicit-little-endian syntax, and Compass forwards those images to a remote archive server using one of the various JPEG or JPEG 2000 compression transfer syntaxes, enabling highly flexible and configurable DICOM image sharing.
• Log and monitor DICOM transactions in a user-friendly, human-readable format.
• Log verbosity that is dynamically configurable via a convenient interface.
• Make multiple client devices appear as a single device to a server.
• Route DICOM store jobs from one SCU to more than one SCP to facilitate testing of new devices.

Typical Scenarios

Scenario 1: Compass can act as a checkpoint where you control which studies enter your PACS. A rule can be defined so that any or all studies get routed to the Hold Queue, where they can be inspected for their patient name, patient ID, accession number, study date, study instance UID, or the modality type. The study can then be sent to a destination, removed, or held until a later date.

Scenario 2: Compass gives the user the ability to give priority to certain jobs by marking any rule as STAT. Data that match this rule will be placed into a job that is marked STAT and will be run before non- STAT jobs also targeted for that particular destination.

Scenario 3: Compass provides powerful view filtering capabilities which allow a user to easily find jobs of interest. Jobs in any state (Sent, Running, etc) can be easily found and tracked, allowing the user to quickly determine when and where data was sent.

Benefits

• Control - Dynamic control of the mappings and related configuration facilitates ease of use.
• Selectivity - Users are able to control and monitor the associations or transactions of interest.
• Flexibility - Optional and configurable logging, diagnostic, and filtering operations may be performed as the messages are forwarded between devices.
