Amend DICOM PS3.21 as follows (changes to existing text are bold and underlined for additions and struckthrough for removals):
Normative and Informative References AIM Model v4 rv48v4.2 NCI 2013/032018/02 Annotation and Image Markup model version <emphasis role="bold"><emphasis role="strikethrough">4</emphasis><emphasis role="underline">4.2</emphasis></emphasis> https://​wiki.nci.nih.gov/​display/​AIM/​Annotation+​and+​Image+​Markup​+-+AIM#​Annotationand​ImageMarkup​-AIM-​AIMModel
Use Cases ... Multiple regions of interest, or multiple measurements and categorical statements about a single region of interest, or about the same real world entity (e.g., lesion) identified with different regions of interest (e.g., at different time points or with different modalities), may be encoded in single or multiple AIM or DICOM SR instances. Whether or not a source AIM or DICOM SR implementation encodes more than one region of interest (and their accompanying measurements and categorical statements) in a single instance or in separate instances, and whether the conversion from one form to the other "bundles" multiple instances into a single instance, or "unbundles" a single instance into multiple instances, is not prescribed. The AIM 4.01 model allows for the encoding of multiple marked up regions and multiple measurements in a single annotation instance, but does not and unlike earlier AIM model versions,provides a mechanism for identifying which markup is associated with which measurement using AIM statements; otherwise it is therefore necessary to assume that all markup applies to all measurements and vice versa. For example, for RECIST measurements that involve the long and short axis of a lesion, though it is currently not onlypossible to encode in AIM (and map to TID 1500) both the boundaries of and area measurements as derived from a planar volumetric ROI, and recognize them by their concept name code, it is not also possible to encode the endpoints of the measured axes of the pair of linear measurements and their derived values. Nor is a reverse mapping of such information encoded in TID 1500 into AIM possible. Some current AIM implementations use private extensions to address this use case, but mapping these is beyond the scope of the Standard. It is expected that a future revision of the AIM 4.0 model will allow for explicit linkage of markup and measurements, probably using statements, e.g., Calculation​Entity​References​Markup​Entity​Statement and Calculation​Entity​References​Segmentation​Entity​Statement, at which time the appropriate mappings will be added.

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. Currently there is noThe AIM mechanism to4.1 model can optionally identify the group of animals imaged at the same time that corresponds to the DICOM SourcePatientGroupIdentificationSequence.
Mapping of DICOM General Study Module The AIM 4.01 model does not provides optional Study identification information per se (i.e., conceptually an AIM instance may exist independent of a Study, but DICOM requires that SR instances be part of a Study). Accordingly, 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, and is described here. If there is more than one DICOM Study referenced by the AIM object, and explicit Study identification information (Image​Annotation​​Collection/​study​Instance​Uid) 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 PS3.3 C.17.2.2 Identical Documents Sequence.

If available, this information shall be used, otherwise a new Series shall be generated since a converted instance, and it 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.

Amend DICOM PS3.21 as follows (changes to existing text are bold and underlined for additions and struckthrough for removals):

The PQ data type is not used in AIM. The Concept Name of the measurement is usually pre-coordinated in a single CalculationEntity/​typeCode entry. If there is more than one CalculationEntity/​typeCode, the first is assumed to be the primary concept and the others may be modifiers that, if recognized as such, may be mapped to method and derivation, or if otherwise recognized and name-value pair of concepts can be constructed can be encoded as generic modifiers, but otherwise have to be ignored. The Numeric Value may be found as the single value of a CompactCalculationResult (i.e., value child of CalculationResult) or the first value of an ExtendedCalculationResult (i.e., nested within calculationResultCollection). This can give rise to a difference in representation in a round trip conversion. Units of measurement shall be converted from a text string (ST) to a Coded Sequence entry using the UCUM Code Values and "UCUM" as the Coding Scheme Designator (in AIM, CalculationResult/​unitOfMeasure is defined as "A string representation of UCUM unit for the value of the calculation"). The AIM CalculationData/​@value shall be assumed to be in the US English locale (i.e., periods are used as the decimal point, not commas, etc.). The length of the AIM CalculationData/​@value ST is not limited, but the DICOM DS value representation is limited to 16 characters. Values of CalculationData/​@value that are too long shall be truncated or rounded to fit in an implementation-dependent manner. The CalculationResult/​dataType (e.g., Double, Integer) is not encoded in the DICOM mapping, since all DICOM SR numeric values are encoded as a Decimal String (DS), so in a round trip from AIM to DICOM and back to AIM will not be recovered (i.e., will always be encoded as Double). For the use cases for this mapping, it is likely that all measurements will be Double anyway. DICOM allows the Measured Value Sequence (0040,A300) to be sent zero length (empty) if there is no value. In such cases the Numeric Value Qualifier Code Sequence (0040,A301) may be used in DICOM to send a code indicating why, either because of an invalid floating point result (e.g., (114000, DCM, "Not a number") corresponding to NaN), or for more general reasons (e.g., (114006, DCM, "Measurement failure")). See . indicates that a non-numeric CalculationData/@value may be mapped to Numeric Value Qualifier Code Sequence (0040,A301). Various possible mappings of AIM string values to a subset of DICOM codes corresponding to are defined in . These are based on the: Java Double.toString(double) definition (see ) No similar standard C or C++ mapping is known to exist (e.g., for libc dtostr() or sprintf()). Other languages offer some flexibility (e.g., Python supports case insensitive variants of "NaN" and "Infinity", the latter with or without a sign; see ). For JavaScript, see , and . The table describes a subset of possible values, the mapping may not be exact (e.g., the definitions of NaN may differ), the mapping is ambiguous (since AIM does not define which string source to use), and the mapping of other values is undefined.

DICOM Image references to AIM Path

Referenced SOP Sequence > Referenced Frame Number IS referencedFrameNumber/​@value INT
An image reference in the AIM tree locally consists of the SOP Instance UID only, without SOP Class, which is described elsewhere in the tree in the imageReferenceEntityCollection (which, similar to the DICOM Current Requested Procedure Evidence Sequence or Pertinent Other Evidence Sequence, also contains the Study and Series level information). Hence the use of the predicate "sopInstanceUid/​@root=$sopInstanceUID" in the path in the table. The AIM version 4.1 model includes an optional AccessionNumber in the imageStudy class used in the imageReferenceEntityCollection. This may be preserved in a DICOM SR instance in the ImageLibrary. DICOM segmentation references may be mapped as specified in .
DICOM Segmentation references to AIM Path

Referenced SOP Sequence > Referenced SOP Instance UID UI ​SegmentationEntity/​sopInstanceUid/​@root II
Referenced SOP Sequence > Referenced Segment Number US SegmentationEntity/​segmentNumber/​@value INT
The SOP Class UID is included locally in the AIM tree with the reference, rather than being factored out into the imageReferenceEntityCollection, in which it is not present. Ideally, all segmentation references would be included in either Current Requested Procedure Evidence Sequence or Pertinent Other Evidence Sequence as appropriate; however t. There is insufficientoptional information in the AIM 4.01 model to support this; i.e.,identify the Study and Series, but if the Study and Series Instance UIDs are absent, andthey cannot safely be assumed to be those of any related images. The reference to the original image that was segmented or a representative image on which the segmentation may be displayed, which may be encodedpresent in SegmentationEntity/​referencedSopInstanceUid/​@root, may be encoded in a separate Content Item if supported by the template (e.g., TID 1410, TID 1411) in (121233, DCM, "Source image for segmentation").
