<Instructions to authors are encapsulated in angled brackets as “< … >” and denoted with italicized text. These instructions are to be deleted in their entirety prior to publication.>
<Use of capitalization: Please follow standard English grammar rules-only proper nouns and names are upper case. For example, “Modality Actor” is upper case, but “an actor which fulfills the role of a modality” is lower case. Do not use upper case to emphasize a word/topic.>
<Note: There are editing conventions, such as diagram numbering and how to use Microsoft Word tools, etc., at http://wiki.ihe.net/index.php?title=Writing_Technical_Frameworks_and_Supplements. Please review this prior to beginning a new Supplement. This is especially useful for first time authors.>
<This Supplement Template is intended for the development of new Profiles or for making significant changes to Profiles, such as adding formal Options. Simple changes to existing Supplements or Profiles should be made using the Change Proposal (CP) process. See the Technical Framework Development section at http://wiki.ihe.net/index.php?title=Process#Technical_Framework_Development for more guidance on Supplements vs. CPs.>
<All of the sections in this document are required. Sections may not be deleted. The outline numbering is intended to be consistent across Profiles and across Domains, so do not adjust the outline numbering. If there is no relevant content for a section, simply state “Section not applicable”, but leave the numbering intact. Sub-sections may be added for clarity.>
<This Supplement Template includes templates for Volumes 1 (Profiles), 2 (Transactions), 3 (Content Modules), and 4 (National Extensions).>
<Volumes 1, 2, and/or 3 are developed together for Public Comment and Trial Implementation submission. Volume 4, National Extensions, is typically developed at a later point in time, usually at Trial Implementation or later. Templates for all four volumes are included in this document for the sake of completeness. If you are beginning a new profile, you are strongly discouraged from using National Extensions and should instead focus on optional data sets or other alternatives. For more information, see http://wiki.ihe.net/index.php?title=National_Extensions_Process.>

IHE <Domain Name>RO Technical Framework Supplement – <Deformable Registration in Radiation Oncology Profile Name (Profile AcronymDRRO)>______________________________________________________________________________
ForewordThis is a supplement to the IHE <Domain Name> Technical Framework <VX.X>. Each supplement undergoes a process of public comment and trial implementation before being incorporated into the volumes of the Technical Frameworks.<For Public Comment:> This supplement is published on <Month XX, 201x> for Public Comment. Comments are invited and may be submitted at http://www.ihe.net/<domain>/<domain>comments.cfm. In order to be considered in development of the Trial Implementation version of the supplement, comments must be received by <Month XX, 201X>. <For Trial Implementation:> This supplement is published on <Month XX, 201X> for Trial Implementation and may be available for testing at subsequent IHE Connectathons. The supplement may be amended based on the results of testing. Following successful testing it will be incorporated into the <Domain Name> Technical Framework. Comments are invited and may be submitted at http://www.ihe.net/<domain>/<domain>comments.cfm.This supplement describes changes to the existing technical framework documents. “Boxed” instructions like the sample below indicate to the Volume Editor how to integrate the relevant section(s) into the relevant Technical Framework volume.Amend section X.X by the following:
Where the amendment adds text, make the added text bold underline. Where the amendment removes text, make the removed text bold strikethrough. When entire new sections are added, introduce with editor’s instructions to “add new text” or similar, which for readability are not bolded or underlined.

Introduction to this Supplement
The DRRO profile defines the content necessary for exchanging DICOM Deformable Spatial Registration (DSR) objects between radiation oncology systems. In addition to defining the data required to accomplish deformable image registration, it provides requirements on data elements so that DSR objects can be appropriately handled by radiation oncology systems that test to this profile.
Open Issues and Questions# Intr.
inDescription
1 Is there a usage for (0064,0010) Post Deformation Matrix?2 Use case “Dose compositor” partially overlaps with DCOM. The use case
involves a Dose Actor and a Dose Compositor Actor. The latter is the same as in DCOM. Do we include this use case (as well the Dose Compositor Actor) in DRRO and how do we differentiate?Include, but make sure that it is reflected in the resulting RT Dose.2019-03-19: There appear to be some limitations in the current DICOM standard preventing storage with relevant references for the Deformable Dose Compositor.
3 Should Use cases “Deformable registration creation” and “Deformable registration editing” be separate use cases or do we merge and use “optional” for consumption of Deformable Spatial Registration Object?2018-02-04: Not clear if Use case “Deformable registration editing” corresponds to any current clinical product. The use case is retained as a placeholder.
4 Contourer Actor is described as propagation of structures but for the use cases also used to describe the action of contouring in fusion view. Should we introduce one more actor (Fusion view contourer actor?)?
5 Do we introduce prerequisites on the RT Dose objects considered (axial?)?6 2019-03-18: Handling of Fiducial (0070,0314 “Used Fiducial Sequence”) was
discussed. This is an Open Issue – could be handled as a Profile Option. The idea would be to use the reference structures (regions and/or points of interest) which have been used to guide the deformable registration algorithm.

7 2019-09-09: Deformable dose compositor actor and deformable compositing planning are moved to later versions of the profile.
8 2020-10-07: Patient Position in the case of PET should be discussed. Expression of patient position in PET is different than the historical way of expressing it in MR and CT. Check this profile and dependent profiles on patient position restrictions

X DX Deformable Registration for Radiation Oncology (DRRO) ProfileThis Integration Profile specifies how images, RT Structure Sets, RT Doses, and associated deformable registration information can be exchanged, stored, processed, and displayed. […] The use of relevant DICOM objects (Deformable Spatial Registration) is clarified and constrained in order to avoid misinterpretations.The Deformable Registration for Radiation Oncology (DRRO) Profile is a Workflow and Content Module profilefocuses on the content for deformable registration and does not define the deformable registration workflow.. The focus is both on a registration workflow and content for image registration and deformation of structure sets and images.

X.4.1 Concepts
X.4.1.1 Deformable Image Registration (DIR)Deformable image registration (DIR) is the process of defining finding a mappingpoint-to-point between the positions in one scan and theirits corresponding positions in another scan. This permits point-wise merging of information in scans acquired of the same subject at different time points or of different subjects and is of high relevance in many aspects of radiation therapy treatmentsaccurate treatment planning and is necessary to evaluate the accumulated dose from a number of radiation therapy treatments.DIR allows for alignment that accounts for changes suchfrom such processes as organ deformation, patient weight loss, or tumor shrinkage. DIR has the perspective of being widely integrated into many different steps of the radiotherapy process including planning, delivery and accumulated dose from radiotherapy. For example, inter-fractional registration can be used to match an image acquired at one treatment fraction to an image from another fraction to improve patient positioning, and to evaluate organ motion relative to bony anatomy. Another particular use is data transfer between images to propagate contours from the planning images or from an atlas to newly acquired images as well as between images of different modalities. Intra-fractional registration is used to match images acquiring during a single treatment fraction. For example, this process is used to track respiratory motion and can be used to generate a model of organ motion across a patient population.Once the registration is complete, the result is recorded in a Deformable Spatial Registration object which is typically stored in the study with the image data.

registration is described through a rigid transform, for initial coarse alignment, and a deformation vector field, for subsequent detailed alignment, see “primary” image data set is the one that shares the same Frame of Reference as the Spatial Registration Object and shall have an identity transformation matrix.Many different There are many deformable image registration algorithms exist. The methods/algorithms for registration: matching fiducials that are visible in the datasets, using operator input to help align the data, correlating the information content in the datasets, etc. Specifying a method/algorithm to use to arrive at the transformation is outside the scope of this profile. The specific algorithm used may be of interest to the user (especially when several different registrations exist between the same datasets). It is therefore relevant that the Deformable Spatial Registration object stores information on the type of algorithm used, for instance if the driving force is image information or fiducial markers in terms of POIs or ROIs so it is recommended that the name and description of the method be recorded in the resulting Deformable Spatial Registration object.
X.4.1.2 Rigid transform and Ddeformation vVector fFieldA deformation vector field is not, in general, invertible. In the use case descriptions, we follow the annotation in DICOM supplement 112 “Deformable Spatial Registration Storage SOP Class”, i.e., the dDeformations and transformations describe how to sample data from the Source Reference Coordinate System (RCS) into the Registered RCS. The deformable spatial registration is applied to the Registered RCS coordinates by:
1. First, transforming the coordinates using a pre deformation matrix; and2. Then, applying the deformation offsets to the resulting coordinates.
The resulting coordinate addresses the corresponding point within the Source RCS. In other words,
Each vector describes the displacement of a point in the Registered RCS to spatially align with the corresponding point in the Source RCS, after having been rigidly aligned through a pre deformation matrix; and
The vector field is defined on the Registered image. Expressed as an equation, a source coordinate can be calculated as:[XSource

Note that a deformation vector field is not, in general, invertible. This is a difference with respect to Spatial Registration object which can be used for rigid alignment in both directions.
X.4.1.3 Deformable Image Registration (DIR)Deformable image registration (DIR) is the process of finding a point-to-point map between
the positions in one scan and its corresponding position in another scan. This permits accurate treatment planning and is necessary to evaluate the accumulated dose from a number of radiation therapy treatments.
DIR allows for alignment that models changes from such processes as organ deformation, patient weight loss, or tumor shrinkage. DIR has the perspective of being widely integrated into many different steps of the radiotherapy process including planning, delivery and accumulated dose from radiotherapy. For example, inter-fractional registration can be used to match an image acquired at one treatment fraction to an image from another fraction to improve patient positioning, and to evaluate organ motion relative to bony anatomy.

Deforming Images, Contours and DoseA deformable image registration can be used to create deformed objects. Contours on the Registered image can be deformed to the Source image following the vector field. The Source image can be deformed to the Registered image and stored as a Deformed image. This allows for instance visualization of the two images fused. A RT Dose defined on the Source image can be deformed to the Registered image and stored as a Deformed Dose. This allows for instance summation of doses on different images.The result of a deformable registration can be used for creating deformed objects in the coordinate system of the registered image. Applying the deformable registration to contours and doses the result is deformed contours and deformed doses respectively.The source image can be stored as a deformed image, which is basically moving the source image coordinate system to the same as the registered image.

The DCOM Profile (rigid dose compositing) requires this attributed to be PLAN or MULTI_PLAN in dose retrieved using transaction [RO-DC1] and MULTI_PLAN in dose stored by the Dose Compositor using transaction [RO-DC2].
Some Use Cases for deformable dose involve BEAM doses. These may need to be supported in the DRRO Profile. Cross-profile compatibility issues need further evaluation.
Use dose summation type of the original dose?
Corresponding requirements in the DCOM Profile may also need to be re-evaluated.
X.4.2.8.2 Dose Compositor Use Case Testing
Can we reuse ideas from DCOM testing for the summation part?
X.4.2.9 Use Case #9: Composite planning, Recurrence Planning, Adaptive Planning
A deformed dose is used as background dose in planning.
X.4.2.9.1 Composite planning, Recurrence Planning, Adaptive Planning Use Case Description
Received:
Two series of images as CT/MR/PET Image Objects – registered Image R and source Image S

A plan with Image R as planning image as RT Plan Object.
A dose on Image S as RT Dose Object.
Action: A Dose Actor allows mapping of Dose S to Image R. A Planner Actor allows to use the deformed dose as background dose for the plan.
Stored: A plan created using the deformed dose as background dose, and Image R as planning image, is stored as RT Plan.
X.4.2.9.2 Composite planning, Recurrence Planning, Adaptive Planning Use Case Testing
Do not include optimization. It is possible to reference a previous plan. But not dose.
X.4.2.YYY Use Case #YYY: Extras Use cases not described above but which have been discussed:
o Use case: Deformable Registration Comparison
A device can display the differences between deformable registrations. The difference here between straight dose comparison is that it can accept the deformable registration and the data that composes it. The actors for this use case may not be different from actors suggested by other use cases (deformable dose compositing, displaying) except that it may have a comparison component and the ability to display deltas with side by side dose displays.
o Surgery Use Case: Resection Cavity Correction (Intra-Op Update) Any interest / relevance to add use case for diagnostic PET/CT - planning CT contouring
in fusion / contour propagation [deformable registration between diagnostic CT and planning CT, while diagnostic PET and planning CT used for fusion / propagation]?
Resampling (images, structures, and dose) is outside the scope of the DRRO profile. This should be pointed out clearly in the description.
