Introduction

AIM version 4 revision 44 48 Radiology and Oncology (called RadOnc) is an extension of the AIM 4.0 foundation modelFoundation Model, which covers fundamental image annotation needs. The RadOnc model has nine new classes that cover Oncology lesion annotation needs. You can download the RadOnc model.

Summary of Changes between

the AIM Foundation and AIM 4.0, Revision

...

48 Models

AIM 4.0 has fifty-five new classes. Twelve classes were renamed and four were deleted. This document describes changes from the AIM 3.0 to the AIM 4.0 foundation information modelFoundation Model. Descriptions of the new classes follow.

...

LesionObservationEntity (RadOnc)

The class is an abstract class stores observations made about lesions in both clinical trial and day-to-day clinical treatments. For detailed informatioinformation, see DICOM Clinical Trials Results Reporting Supplement (Working group 18).

...

GeneralLesionObservationEntity (RadOnc)

This class contains general observations made about lesions in clinical trial results and day-to-day clinical treatment that are not specific to time point. For detailed information, see DICOM Clinical Trials Results Reporting Supplement (Working group 18).

...

TimePointLesionObservationEntity (RadOnc)

This class contains observations made about lesions in day-to-day clinical interpretations and clinical trial results at a specific time point. It also includes “lesions” that are created for the purpose of calibrating scanned film or other secondary capture images. For detailed information, see DICOM Clinical Trials Results Reporting Supplement (Working group 18).

Classes derived from AnnotationOfAnnotationStatement

AnnotationOfAnnotationHasGeneralLesionObservationEntityStatement (RadOnc)

An instance of annotation of annotation may have one or more general lesion observations associate with it. AnnotationOfAnnotationHasGeneralLesionObservationEntityStatement represents a direct relationship between an instance of annotation of annotation and general lesion observation. If you have two general lesion observations, you will need to create two statements.

...

1. Create a general lesion observation instance.
2. Create an AnnotationOfAnnotationHasGeneralLesionObservationEntityStatement statement linking the annotation of annotation (subjects) to the general lesion observation (objects).

AnnotationOfAnnotationHasTimePointLesionObservationEntityStatement (RadOnc)

An instance of annotation of annotation may have one or more time-point lesion observations associate with it. AnnotationOfAnnotationHasTimePointLesionObservationEntityStatement represents a direct relationship between an instance of annotation of annotation and time-point lesion observation. If you have two time-point lesion observations, you will need to create two statements.

...

1. Create a time-point lesion observation instance.
2. Create a AnnotationOfAnnotationHasTimePointLesionObservationEntityStatement statement linking the annotation of annotation (subjects) to the time-point lesion observation (objects).

Classes derived from ImageAnnotationStatement

The following classes were derived from ImageAnnotationStatement.

GeneralLesionObservationEntityHasImgingPhysicalEntityStatement (RadOnc)

The class is used to record a relationship between a general lesion observation entity and imaging physical entity. Each lesion observation can only be directly related to one imaging physical entity.

...

1. Create an imaging physical entity instance.
2. Create a general lesion observation entity instance.
3. Create an GeneralLesionObservationEntityHasImagingPhysicalEntityStatement statement linking the general lesion observation entity (subjects) to the imaging physical entity (objects).

ImageAnnotationHasGeneralLesionObservationEntityStatement (RadOnc)

An instance of image annotation may have one or more general lesion observations associate with it. ImageAnnotationHasGeneralLesionObservationEntityStatement represents a direct relationship between an instance of image annotation and general lesion observation. If you have two general lesion observations, you will need to create two statements.

...

1. Create a time-point lesion observation instance.
2. Create an ImageAnnotationHasTimePointLesionObservationEntityStatement statement linking the annotation of annotation (subjects) to the time-point lesion observation (objects).

ImageAnnotationHasTimePointLesionObservationEntityStatement (RadOnc)

An instance of image annotation may have one or more time-point lesion observations associate with it. ImageAnnotationHasTimePointLesionObservationEntityStatement represents a direct relationship between an instance of image annotation and time-point lesion observation. If you have two general lesion observations, you will need to create two statements.

...

1. Create a time-point lesion observation instance.
2. Create a ImageAnnotationHasTimePointLesionObservationEntityStatement statement linking the image annotation (subjects) to the time-point lesion observation (objects).

TimePointLesionObservationEntityHasImgingPhysicalEntityStatement (RadOnc)

The class is used to record a relationship between a timepoint lesion observation entity and imaging physical entity. Each lesion observation can only be directly related to one imaging physical entity.
