3D Slicer is a multi-platform, free open source software (FOSS) for visualization and image computing. The navigation box on the left leads to additional pages with more information.
Featured Image: A computer modeling tool for comparing novel ICD electrode orientations in children and adults.
Top Row: Examples of nonstandard subcutaneous, epicardial, and transvenous electrode orientations. Left: Infraclavicular can with single subcutaneous electrode. Middle: Abdominal can with epicardial lead. Right: Infraclavicular can with superior vena cava and right ventricular transvenous electrode as well as left subcutaneous electrode.
Bottom Row: User interface for electrode placement. A subcutaneous electrode (red) extending left posterior with right abdominal can (green) is shown in a 2-year-old torso shown in 2 views used while placing electrodes in a finite element model. Moveable cutting planes allow the user to examine anatomical detail during electrode placement. The blue spheres on the red electrode and bounding cage on the can indicate handles for user interaction. Electrodes can be placed with similar precision in epicardial and transvenous orientations.
