Segmentation Display Tool

The SegmentationDisplayTool is a Tool inside Cornerstone3DTools. Similar to other tools it should be added first via addTools and then to a ToolGroup that is going to use it for displaying the segmentations.

Usage‚Äč

Below we show you how to use the SegmentationDisplayTool to display a labelmap segmentation representation for a toolGroup.

import {
addTool,
segmentation,
SegmentationDisplayTool,
ToolGroupManager,
} from '@cornerstonejs/tools';

const segmentationId = 'segmentationId';
const toolGroupId = 'segmentation-display-tool-group';
const viewportId = 'segmentation-display-viewport';

// Adding it to internal state of cs3DTools
addTool(SegmentationDisplayTool);

const toolGroup = ToolGroupManager.createToolGroup(toolGroupId);

// adding viewports to the toolGroup
toolGroup.addViewport(viewportId);

// adding tool to the toolGroup
toolGroup.addTool(SegmentationDisplayTool.toolName);

// setting tool to enabled in order to be show the segmentations
toolGroup.setToolEnabled(SegmentationDisplayTool.toolName);

// adding the segmentation to cornerstone3DTools segmentation state
segmentation.addSegmentations([
{
segmentationId,
representation: {
type: Enums.SegmentationRepresentations.Labelmap,
data: {
volumeId: segmentationId,
},
},
},
]);

// create a labelmap representation of the segmentation and add it to the toolGroup
await segmentation.addSegmentationRepresentations(
toolGroupId,
[
{
segmentationId,
type: Enums.SegmentationRepresentations.Labelmap,
},
],
toolGroupSpecificRepresentationConfig
);
