| DICOM PS3.21 2024d - Transformations between DICOM and other Representations |
|---|
The transformation is described in one direction, by enumerating the structures in the target (DICOM SR TID 1500) and describing where in the source (AIM v4) the corresponding information may be obtained. The information is tabulated in a manner that can be implemented as an automated "pull" conversion of an AIM instance into a DICOM SR instance, such as might be described using a transformation language such as XSLT. The transformation is intended to be reversible, i.e., by inverting the target and the source, even though round-trip full fidelity will not be achieved in some cases. Gaps that exist in the information required in the target to create a compliant object, which need to be filled by information from an out of band source or generated de novo , are highlighted. Information in the source that is not "pulled" into the DICOM encoding will be lost; these omissions are deemed to be harmless from the perspective of the relevant use cases.
The tabular representations make use of the following conventions in order to simplify the automatic extraction and use as a formal syntax to drive implementations:
DICOM Attributes are represented by keywords defined in PS3.6, rather than specifying the data element group and element tags.
DICOM Attributes that are nested within sequences are shown as a path from the top level Data Set separated by a ">" symbol.
AIM classes, attributes and associations are represented using their XPath representation as encoded in XML instances.
DICOM Code Sequence Attributes are mapped from AIM CD data type attributes without fully enumerating the corresponding subordinate DICOM Attributes and XML elements and attributes.
Other DICOM Sequences are listed, without a mapping on the same row, but with the following rows describing the individual DICOM Attributes nested within that Sequence.
All source and target paths are fully qualified relative to the root of the instance in order to make the transformation reversible. I.e., it would be possible to describe some transformations using the descendant-or-self axis XSLT operator ("//") if the source were unambiguous but that would not specify the location reversibly as a target. Accordingly, some of the explicit paths are quite long.
The requirement type for DICOM Attributes is as defined in PS3.3 for Attributes in Modules and Attribute Macros, except that if the containing Module in the IOD is not required, e.g., is U rather than M, then a mandatory (Type 1 or 2) Attribute in a user optional (type U) Module is shown as optional (Type 3).
The data type and cardinality are specified for both the source and the target, to highlight potential mismatches that may occur during transformation. For nested elements and attributes, the multiplicity is expressed as the combination of the multiplicity along the entire path. For example, the aim:name attribute has a multiplicity of 1:1 in an aim:Person class but is associated with the aim:ImageAnnotationClass with a multiplicity of 1 -> 0:1, so the multiplicity is indicated as 0:1, not 1:1, since that is the net effect. The DICOM multiplicity is either the VM for the data element or the number of Sequence Items if the data element is a Sequence.
The XML representation of the AIM UML collapses some associations and classes such that they are encoded as a single element, and this is reflected in the mapping paths. For example, the aim:Person class has an aim:person association from the aim:ImageAnnotationCollection class, so the path to the aim:name attribute is expressed as /ImageAnnotationCollection/person/name, as it appears in the XML instance.
Data type transformations are assumed and are not described further unless there is a specific requirement. For example, conversion from DICOM DA, TM and DT VR Attributes to AIM TS Data Type values is implicit, including extraction/population of the appropriate sub-fields (i.e., only the date portion of a TS is used when creating a DICOM DA value).
If value sets are defined for both AIM and DICOM, then value mappings are described. In some cases, explicit value sets are not defined. For example, aim:Person/sex has no explicitly defined value set but maps to DICOM PatientSex, which does; so if AIM implementations use the DICOM values, and the values are copied, then the transformation without value mapping will be successful, but not otherwise.
When a mapping is defined but no transformation source is available but a value is required, a Generated Value is indicated, which may be a fixed constant (e.g., a Modality value of "SR"), an indication that an empty (zero length) value or sequence is required, or an indication that a new value of the appropriate VR needs to be generated (e.g., a new UID for a UI VR, a new integer for an IS VR, etc.). The need to generate new values will not produce a deterministic result without a memory of previous conversions.
Optional content in the target that has no defined source is not described (e.g., DICOM SeriesDescription in the General Series Module has no correlate in AIM, though it would be useful to populate with a generated value).
When the same DICOM Attribute is described in two different Modules, the more specialized (restrictive) use is described in the mapping tables. E.g., InstanceNumber is Type 3 in the SOP Common Module but Type 1 in the SR Document General Module, so it is only described in the latter.
Capitalization and punctuation of DICOM keywords and AIM class, attribute and association names are significant.
General Remarks on the mapping of DICOM header Module Attributes:
Mapped AIM objects are considered "unverified", so there is no requirement to record the identity of the Verifying Observer; if the "recording" observer identity is required (aim:user class attributes) it may be mapped to Author Observer Sequence (0040,A078) in the SR Document General Module (and entries in Observation Context in the Content Tree are not needed).
Attributes of the Predecessor Documents Sequence (0040,A360) and Identical Documents Sequence (0040,A525) are not described in this transformation since they are relevant only in the context of a managed DICOM SR document environment and have no correlate in AIM.
Attributes of the Current Requested Procedure Evidence Sequence (0040,A375) and Pertinent Other Evidence Sequence (0040,A385) are described in the transformation and provide the information described in the Hierarchical SOP Instance Reference Macro used to match composite instance references with their Study and Series context; the AIM DicomImageReferenceEntity class performs a similar function.
Attributes of the Equivalent Document Sequence (0040,A090) are not described in the transformation since they are relevant only in the context of the original DICOM SR document.
The name space of the AIM elements is elided, and is implied to be "gme://caCORE.caCORE/4.4/edu.northwestern.radiology.AIM".
Timezone Offset From UTC (0008,0201) shall be considered for Attributes of the DICOM SR document that are based on the DA or TM data type (PS3.5). AIM date and time attributes may or may not contain explicit timezone information that may be extracted to populate Timezone Offset From UTC (0008,0201).
The Specific Character Set (0008,0005) is required (Type 1C), if the Basic Graphic Set is expanded or replaced. This is the basis for mapping DICOM character sets to AIM XML Unicode (<?xml version="1.0" encoding="UTF-8"?>).
Ambiguities exist for mapping individual characters to Unicode (e.g., for Japanese characters). Resolution of those issues is beyond the scope of this document. Please refer to Section A.8 for further details on data types and character sets.
Table A.6.1.1.1-1. Mapping of DICOM Patient Module
If the annotation concerns a small animal that has been imaged as part of a group of animals in the same image, then the PatientID and other Attributes of this Module will be those of that individual animal, not the group. The AIM 4.2 model can optionally identify the group of animals imaged at the same time that corresponds to the DICOM SourcePatientGroupIdentificationSequence.
No mapping of the DICOM Clinical Trial Subject Module is described since no corresponding content is present in the AIM model.
The AIM 4.2 model provides optional Study identification information. If available, this information shall be used during transformation from AIM to SR, otherwise either a new Study may be generated, or the SR instance derived from the AIM object could be placed in (one of) the Study(ies) referenced by the AIM instance, assuming there are any, which produces a predictable transformation.
If there is more than one DICOM Study referenced by the AIM object and explicit Study identification information (ImageAnnotationCollection/studyInstanceUid) is absent, duplicates of the converted AIM SR instance may be placed in each of the referenced studies (with different SOP Instance UIDs), in which case the IdenticalDocumentsSequence is required in the SR Document General Module; see Section C.17.2.2 “Identical Documents Sequence” in PS3.3 .
Table A.6.1.1.3-1. Mapping of DICOM General Study Module
No mapping of the DICOM Patient Study Module is described since no corresponding content is present in the AIM model.
No mapping of the DICOM Clinical Trial Study Module is described since no corresponding content is present in the AIM model.
The AIM 4.2 model optionally supports the concept that an annotation itself is part of a Series. If available, this information shall be used, otherwise a new Series shall be generated since a converted instance cannot be made part of a referenced image Series, if any, because of the rule that all instances of a Series are generated on the same Equipment.
Table A.6.1.1.6-1. Mapping of DICOM SR Document Series Module
No mapping of the DICOM Clinical Trial Series Module is described since no corresponding content is present in the AIM model.
Table A.6.1.1.8-1. Mapping of DICOM General Equipment Module
Table A.6.1.1.9-1. Mapping of DICOM SR Document General Module
All the Attributes in the SR Document Content Module are transformed by processing the DICOM SR Content Tree, and accordingly are not described in the same tabular manner as the "header" Attributes, since the mapping depends on the DICOM SR template structure. The Attributes common to each Content Item of the Content Tree are:
Each child Content Item with a "by-value" relationship with its parent also contains:
The additional required Attributes in each Content Item depend on the ValueType:
NUM - MeasuredValueSequence, MeasuredValueSequence>NumericValue, MeasuredValueSequence>MeasurementUnitsCodeSequence
COMPOSITE - ReferencedSOPSequence, ReferencedSOPSequence>ReferencedSOPClassUID, ReferencedSOPSequence>ReferencedSOPInstanceUID
IMAGE - ReferencedSOPSequence, ReferencedSOPSequence>ReferencedSOPClassUID, ReferencedSOPSequence>ReferencedSOPInstanceUID, ReferencedSOPSequence>ReferencedFrameNumber, ReferencedSOPSequence>ReferencedSegmentNumber
SCOORD3D - ReferencedFrameOfReferenceUID, GraphicData, GraphicType
CONTAINER - ContinuityOfContent, ContentTemplateSequence, ContentTemplateSequence>MappingResource, ContentTemplateSequence>TemplateIdentifier
ObservationUID is required for the following Content Items in order to propagate the aim:uniqueIdentifer information:
IMAGE - for (121191, DCM, "Referenced Segment") Content Item corresponding to aim:SegmentationEntity
CONTAINER - for (126200, DCM, "Image Library Group") Content Item corresponding to aim:ImageReferenceEntity
CONTAINER - for (125007, DCM, "Measurement Group") Content Item corresponding to aim:ImageAnnotation
NUM - for any Content Item corresponding to aim:CalculationEntity
SCOORD - for any Content Item corresponding to aim:MarkupEntity
ObservationDateTime is required for the following Content Items in order to propagate the aim:dateTime information:
Table A.6.1.1.11-1. Mapping of DICOM SOP Common Module
|
The fixed value is the SOP Class UID of the Enhanced SR Storage SOP Class, which is sufficient unless SCOORD3D are used, in which case the Comprehensive 3D SR Storage SOP Class is required, which has a UID of "1.2.840.10008.5.1.4.1.1.88.34". |
||||||||
|
Generated if more than one converted instance in separate studies. |
||||||||
|
The fixed generated value corresponds to the normal UTF-8 specified in the XMLDecl of the XML prolog [XML] in the AIM instance. Other values may be used if they are sufficient to describe all the encoded characters in the transformed instance. E.g., it may be omitted entirely if all the characters are US-ASCII. |

The fixed generic code value is suggested in lieu of AIM containing any information about the imaging procedure, so more specific procedure codes such as those from CID 100 “Quantitative Diagnostic Imaging Procedure” cannot be used. If out of band information is available, a more appropriate code can be used. |
