The Annotation and Image Markup (AIM) standard integrates the description of pixel meaning with user-generated graphical symbols placed on the image into a single common information source. The AIM data model defines the information needed to capture many types of image semantic content, i.e. AnatomicEntity, AnatomicEntityCharacteristic, ImagingObservation, ImagingObservationCharacteristic and Inference. This information is used to aggregate clinical image findings and is collected using standard vocabularies such as RadLex, SNOMED, and DICOM, as well as user-defined controlled terminology. To facilitate AIM annotation creation, an AIM template schema and web-based application have been developed.

The AIM information model is, of necessity, complex and comprehensive. It is intended to apply to many medical image annotation use cases. In the majority of cases, whether for a particular application or clinical trial, the user wants to make simple and constrained annotations.

To facilitate this creation of constrained annotations, the AIM template project provides a web based mechanism to create and store templates locally or in an on-line library. The web based application is based on a new AIM template schema. Instances of AIM templates are created by selecting components to be filled in by the annotator. Terms to be used by the annotator can be selected from standard vocabularies and the use of the terms by the annotator specified. The web browser interface allows for editing, renaming and deletion of a template that belongs to the user on a server. The system automatically validates saved templates against the schema to ensure the annotation will match the AIM model. An image display application can import the template to instantiate a user interface to capture the desired, constrained annotation.

We have created an AIM template schema and web-based application for creating annotation templates. The template schema does not dictate how a graphical user interface can be arranged and implemented. It is platform and application-independent. The web application permits users to define custom templates that can be used with any AIM-compliant image annotation tool.
