LEADTOOLS High Level PACS Framework

PACS

The LEADTOOLS High Level PACS Framework builds upon the LEADTOOLS DICOM Communications classes by implementing high-level client (SCU) and server (SCP) classes. These classes encapsulate LEAD's years of medical imaging development experience to provide an extensible, programmer-friendly framework for rapid application and system development.

Overview of High Level PACS Framework SDK Technology

The LEADTOOLS High Level PACS Framework requires very little knowledge of the internal workings of DICOM communications. Because the framework handles all of the low level communications, developers are free to devote more time to user interface and database queries. Since these classes are built upon the foundation of LEAD's low level DICOM communications layer, they still provide the same power and flexibility to handle any situation.

DICOM PACS Client

The LEADTOOLS High Level PACS Framework provides classes to do common operations including C-ECHO, C-GET, C-STORE, C-FIND, and C-MOVE. The framework handles all of the low level DICOM communications such as connection, association, and message handling processes internally.

DICOM PACS Server

With the service based architecture of the LEADTOOLS High Level PACS Framework, developing a PACS server hosting SCPs is done with minimal time and code. Multiple SCPs may be hosted on the same server, each one running as an individual Windows Service, providing isolation and security. Each framework service handles all of the low level communication, freeing the developer to implement system specific logic for services such as C-FIND, C-MOVE and C-GET. Developers may even further divide the framework service add-ins by SOP class and transfer syntax for more flexibility to implement specific business logic. For example, the add-ins may be segmented to store CT and MR images into different databases. The LEADTOOLS PACS Imaging SDK includes fully functional sample add-in implementations for security, C-MOVE, C-FIND, MWL, C-STORE and Storage Commit.

DICOM PACS High Level Framework Add-ins

The following is a list of framework add-ins included with the LEADTOOLS High Level PACS Framework. These framework add-ins may be used as is or modified to meet the specific needs of any system. Additionally, developers may create completely new custom add-ins.

  • C-MOVE
  • C-STORE
  • C-FIND
  • MWL - Modality Work List
  • MPPS - Modality Performed Procedure Step
  • Storage Commit
  • DICOM Router

DICOM Router Add-in

The LEADTOOLS DICOM Router Add-in implements rule based image routing or forwarding to any local or remote DICOM listening service. This add-in provides a DICOM Storage provider service for all DICOM Storage objects. It processes the images it receives from a client according to preconfigured rules. Based on the outcome, it forwards the images to configured PACS or Workstations.

A rule script editor is provided to help define custom rules based on source application or attribute value(s) in any DICOM tags in the receiving object. The service also allows secure image forwarding using the TLS security profile of the DICOM standard.

DICOM Storage Server Application

The LEADTOOLS PACS DICOM Storage Server Application is a fully functional, OEM-ready application with source code designed for easy branding and customization. It uses the high level PACS Server Framework as service application (daemon) and implements following DICOM Services as service class provider (SCP / Server):

  • Verification service (C-ECHO or DICOM Ping)
  • Different level of Study Root Query/Retrieve Information Model – FIND service
  • Different level of Study Root Query/Retrieve Information Model – MOVE service
  • Full Level 2 DICOM Storage Service for all Standard SOP Classes
  • Storage Commitment Service
  • Modality Work-list (MWL) Service
  • Modality Performed Procedure Steps (MPPS) service

In addition, the LEADTOOLS DICOM PACS Server also implements the following real-world functionalities and customizable add-ins:

  • Simple and easily customizable user interface
  • Custom database schema interfacing
  • Handling simultaneous TCP/IP client connections
  • Large query pagination
  • Logging Add-in that supports many filtering and searching options including automatic export of logs
  • Patient Updater Add-in that includes a patient/study management client that allows users to move, merge, and update patient information using DICOM communications
  • Auto-Copy Add-in that automatically routes retrieved DICOM image data to multiple storage locations
  • Gateway Add-in that acts as a query/retrieve proxy, automatically relaying a single query/retrieve message to any number of external DICOM servers
  • Forwarding Add-in that allows DICOM image data to be automatically forwarded to another PACS server immediately upon storage or on any schedule
  • Administrative options including setting permissions for both users and AE titles
  • On-the-fly transfer syntax re-encoding based on established association
