Other modules include:

• Locator: connects Slicer to a server that feeds a real-time stream of coordinates from a device called the locator.
• Realtime: enables the locator's real-time coordinates to control Slicer.
• Guidance: positions two spherical targets (red and yellow) in the 3D view window to support reformatting volumes.
• EMSegment: implements the Expectation-Maximization segmentation algorithm.
• Custom: a template to help you to create your own modules for Slicer.
• Anatomy: saves files from a Slicer scene to use with the Surgical Planning Lab's Anatomy Browser.
• CustomCsys: lets developers add a Coordinate System actor to their module.
• ModelHierarchy: displays the hierarchy of models.
• Options: reorganizes the order of the modules and hides unnecessary modules.
• SessionLog: records information about a segmentation session for Slicer development purposes.
• Tester: allows the developer to test modules.
• TetraMesh: reads in a Tetrahedral Mesh and converts it into a model.
• VolRend: selects the volume rendering method: Composite, MIP (Maximum Intensity Projection), or Isosurface.
• VolumeMath: adds and subtracts volumes; finds the distance between two points in a volume.
• ModelCompare: shows point correspondences and models in 2D.
