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:
Two Workflows are described by this profile:
• 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.
* '''Discrete''' Positioning and Delivery Workflow involves positioning a patient and subsequent treatment delivery performed by '''separate devices'''.
• The Treatment Delivery Device (TDD) then delivers the intended treatment.
* '''Integrated''' Positioning and Delivery Workflow involves positioning a patient and subsequent treatment delivery both performed by a '''single device'''.

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>
Discrete Positioning and Delivery Workflow involves:

Image Registration Integration Profile focuses on content for image registration and does not define a registration workflow. Such workflow could be managed by using mechanisms described in the Post-Processing Workflow Integration Profile.

The Image Registration Profile does not specify the use of quantification methods for the image data that is created or displayed.

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


Summary

Two Workflows are described by this profile:

  • Discrete Positioning and Delivery Workflow involves positioning a patient and subsequent treatment delivery performed by separate devices.
  • Integrated Positioning and Delivery Workflow involves positioning a patient and subsequent treatment delivery both performed by a single device.

Benefits

  • interoperability between multi-vendor radiotherapy systems

  • The Patient Positioning System (PPS)
    • acquires a set of 2D (planar projection) or 3D (CT) positioning images

    • repositions the patient if necessary
  • The Treatment Delivery Device (TDD)
    • delivers the intended treatment to the already correctly positioned patient
