This Integration Profile specifies how images, RT Structure Sets, RT Doses, and associated spatial registration information can be exchanged, stored, processed and displayed. For a display workstation, it is essential that a workstation correctly identifies the corresponding image sets, matches data from single-slice and multi-slice datasets, matches coordinate systems, and performs spatial translations. The use of relevant DICOM objects (Spatial Registration) is clarified and constrained in order to avoid misinterpretation.<br>

The Radiotherapy Treatment WorkFlow (TRWF) integrates daily imaging with radiation therapy treatments using workflow.

Summary

Two Workflows are described by this profile:

  • the Discrete Positioning and Delivery Workflow Profile involves the positioning of a patient and subsequent treatment delivery, where the positioning and delivery are performed by separate devices.
  • the Integrated Positioning and Delivery Workflow Profile involves the positioning of a patient and subsequent treatment delivery, where the positioning and delivery are performed by a single device.

Benefits

  • Provides transactions required for interoperability between multi-vendor systems

Details

The Discrete Positioning and Delivery Workflow Profile involves the positioning of a patient and subsequent treatment delivery, where the positioning and delivery are performed by separate devices, as follows:

  • The Patient Positioning System (PPS) acquires a set of 2D (planar projection) or 3D (CT) positioning images, performs a registration with previously retrieved reference images, and repositions the patient if necessary. Note that for this profile, the output of these steps is the fact that the patient positioning has been successfully performed.
  • The Treatment Delivery Device (TDD) then delivers the intended treatment.


The Integrated Positioning and Delivery Workflow Profile involves the positioning of a patient and subsequent treatment delivery, where the positioning and delivery are performed by a single device, as follows: • The Positioning and Delivery System (PDS) acquires a set of 2D (planar projection) or 3D (CT) positioning images, performs a registration with previously retrieved reference images, and repositions the patient if necessary. It then delivers the intended treatment.
