Features in the AIM 4.0 Toolkit

The Annotation and Image Markup (AIM) information model version 4.0 has evolved in response to the feedback and changing requirements from the imaging community. The model has become more flexible and expressive. It defines AIM statements that describe a finding found on an image or series of images. These statements represent a relationship between the subject and object entities in the AIM foundation model. A class name that ends with “entity” can be used to create an AIM statement.

AIM 4.0 has two models, AIM Foundation and AIM 4.0. The AIM Foundation model can be extended by imaging experts in a domain area such as molecular imaging and optical imaging. These experts can add additional classes to capture information currently not available in the AIM Foundation model. The AIM 4.0 model includes classes that are required to capture lesion tracking in the domains of radiology and oncology.

The AIM 4.0 Toolkit has the following new features:

  • Fully supports the ISO 21090 data type
  • Collects a question as a coded term for an annotation role entity, imaging physical entity (formerly known as anatomic entity), imaging physical entity characteristic, imaging observation entity, imaging observation entity characteristic, inference entity, calculation entity, task context entity, text annotation entity, DICOM segmentation entity, markup entity, URI image reference entity, or DICOM image reference entity
  • Explicitly captures relationships between entity classes in the AIM model via an AIM statement
  • Has the ability to store a three-dimensional graphical markup
  • Has the ability to store a lesion observation with or without a time point
  • Allows the storage of calculation results in a compressed format
  • Allows a workflow or task context assignment
  • Allows more than one AIM instance in one AIM file or collection
  • Supports post-coordinate terms (combines existing terms to create a new concept)

Logical Data Models for AIM 4.0 and AIM Foundation

The AIM Foundation Model Model is available.

The AIM 4.0 Radiology and Oncology Information Model is also available.
