Module Description

The purpose of the Reporting module is to provide Slicer interface for creating image annotations/markup that are stored in a structured form, and can be exported into Annotation Image Markup (AIM) XML-based format. Currently, Reporting module allows to create three types of markup:

• point (fiducial)
• 2-d measurement (ruler)
• 3-d segmentation (label map).

The 3-d segmentations are stored as binary image masks, and are serialized into DICOM Segmentation Storage objects, which in turn can be referenced from the AIM XML document.

Please note that this module is under active development, and is being made available for the purposes of beta testing and feedback evaluation! The functionality, GUI and workflows may change in the subsequent releases of the module.

Use Cases

This module is designed for the use cases that require creation and/or exchange of self-containing documents describing a certain finding in a DICOM image, such as lesions and anatomical structures.

Tutorials

Panels and their use

The steps to create a new report are the following:

An DICOM imaging study that will be annotated should be loaded into Slicer DICOM database using Slicer DICOM module. If you are unsure what this means, see documentation of the DICOM module. In the Reporting module, new report should be created (see explanation of the module GUI panels below) (Input panel) The volume that will be annotated should be selected (Input panel). Following this, the slice viewers will be initialized to show the volume being annotated. The name of the structure should be selected from the Slicer terminology list by clicking the colored patch in the Annotation panel. Fiducial and ruler markup elements should be placed only in those slice viewers that correspond to the image acquisition plane. Those slice viewers will be listed in the Markup panel of the module. To place a new fiducial/ruler markup elements, corresponding controls in the Slicer toolbar should be used (see on the right). The tree view in the module Markup panel will be showing all markup elements that have been added to the active report. To attach a 3-d segmentation to the report, the segmentation image should be either loaded from file and added to Slicer scene (see instructions on how to use Data module), or a new segmentation should be created using the "Segmentation volume" drop-down. Segmentation can then be edited using the Editor module. "Save Report into AIM format" button can be used to save the report into AIM XML format. "Load Report from AIM format" button can be used to load the report back into Slicer.

Slicer toolbar buttons that should be used for placement of fiducial/ruler markups.

GUI of the module contains the following elements:

Input panel Report: active report being edited Annotated volume: volume being annotated Annotation panel contains the name of the structure being annotated and the colored patch showing the label color. Clicking the colored patch will bring up the selection of the supported named structures. Currently supported terminology is based on Slicer General Anatomy Colors lookup table. Integration of this table with Radlex terminology is planned for the future. Markup panel contains the text listing the slice viewers that should be used for placing fiducial/ruler markups. Tree view widget shows the markups that are associated with the report. The "eye" button toggles visibility of the markup element. Clicking right mouse button over the name of the markup brings up the menu that allows to rename/delete the markup, or to jump to the slice where the markup is placed. Segmentation panel Segmentation volume selector allows to choose the volume containing the segmentation, or to create a new segmentation. Save/Load buttons allow to export/import the report into AIM format.
