SlicerAutoscoperM (SAM) is a free, open source and multi-platform 3D Slicer extension being developed for image-based 3D motion tracking of skeletal structures.

SAM includes modules for Pre-Processing, 3D tracking of structures captured via single, bi-, and multi-plane videoradiography (Autoscoper), 3D registration of structures captured via 4DCT Sequential 3DCT or MRI (Hierarchical 3D Registration) and a Sample Autoscoper data Tracking Evaluation module.

Current Features

  • N-plane Videoradiography - Track 3D motion from 1 or more videoradiographs.
  • 4DCT Registration - Segmented 3DCT structures registered in each frame using Elastix
  • Ridged Body Kinematics - Track the motion of ridged bodies in 3D space with 6 degrees of freedom.
  • Pre-Processing Module - Generate segmentations and extract ridged bodies from 3DCT images.
  • Sample Data - Download sample data to test SAM’s features.

What are we working on?

Below are some features currently under development:

  • Collision Detection - Detect collisions between ridged bodies to inform the optimization process.
