Segmentation information: for each segmentation visible at that position For label volumes the label name corresponding to the voxel value is also displayed. Volume name, or None if no volume is selected for that layer. Layer type: L (label), F (foreground), B (background). Volume layer information: three lines, one for each volume layer For a clinical image Sp: 2.5 means that slices are 2.5mm distance from each other. Slice spacing: distance between slices in this orientation. View orientation: Axial, Sagittal, Coronal for standard anatomical orientations, and Reformat for any other orientation. For example (R 17.6, P 35.3, S 12.1) for a clinical image means that the current position is 17.6mm to the right from the origin, 35.3mm towards posterior, 12.1mm superior from the origin. The origin - (0,0,0) position - was chosen by the imaging technologist when the image was created. Slice view name: Red, Green, Yellow, etc.Īnatomical position: three coordinate values, prefixed with R/ L (right/left), A/ P (anterior/posterior), S/ I (superior/inferior). Slice view information (displayed when the mouse is over a slice view): It displays information about view content at the position of the mouse pointer: Data Probe ¶ĭata Probe is located at the bottom of the module panel.

Current module can be selected using the Module Selection toolbar. This panel (located by default on the left side of the application main window) displays all the options and features that the current module offers to the user. Slicer package contains over 100 built-in modules and additional modules can be installed by using the Extensions Manager.

Modules typically do not interact with each other directly: they just all operate on the data nodes in the scene. Slicer provides a large number “modules”, each implementing a specific set of functions for creating or manipulating data in the scene. Each data set, such as an image volume, surface model, or point set, is represented in the scene as a “node”. Slicer stores all loaded data in a data repository, called the “scene” (or Slicer scene or MRML scene).
