I have already gone through following open source software for Building a 3D model of femur fracture bone
1. ITKSNAP
2.3D slicer.
3.INVESALIUS 3.1.1
4. Image J
I am expecting selection of software based on availability of tutorials and easiness of handling it since I am a beginner in this area . Kindly suggest where I will get sample fracture femur bone i.e datasets to start my work
