Class: DragProbeTool

ProbeTool let you get the underlying voxel value by putting a probe in that location. It will give index of the location and value of the voxel. You can use ProbeTool in all perpendicular views (axial, sagittal, coronal). Note: annotation tools in cornerstone3DTools exists in the exact location in the physical 3d space, as a result, by default, all annotations that are drawing in the same frameOfReference will get shared between viewports that are in the same frameOfReference. Probe tool's text box are dynamically generated based on the viewport's underlying Modality. For instance, if the viewport is displaying CT, the text box will shown the statistics in Hounsfield units, and if the viewport is displaying PET, the text box will show the statistics in SUV units.

The resulting annotation's data (statistics) and metadata (the state of the viewport while drawing was happening) will get added to the ToolState manager and can be accessed from the ToolState by calling getAnnotations or similar methods.

To use the ProbeTool, you first need to add it to cornerstoneTools, then create a toolGroup and add the ProbeTool to it. Finally, setToolActive on the toolGroup

cornerstoneTools.addTool(ProbeTool)

const toolGroup = ToolGroupManager.createToolGroup('toolGroupId')

toolGroup.addTool(ProbeTool.toolName)

toolGroup.addViewport('viewportId', 'renderingEngineId')

toolGroup.setToolActive(ProbeTool.toolName, {
bindings: [
{
mouseButton: MouseBindings.Primary, // Left Click
},
],
})
