Target

1. Create visualization of experimental tests in modeling (image) coordinate system.
2. Prepare experimental data for model inputs.

Tibiofemoral Joint

1. Download joint mechanics .zip file from Downloads page.
2. Download the desired registration markers and bone STLs (place in folder named mri-oks00x, where x is the specimen ID).
   • 3 registration marker stls for tibia
   • 3 registration marker stls for femur
   • stl for tibia bone
   • stl for femur bone

3. Create registration xml (Example Registration XML)

4. Run script from command line Script

   1. Change directory to desired OpenKnee specimen (e.g. oks001)

   2. Run convert_to_image_CS.py <oks00x_registration_0x> <1>

Example using oks001 - 004_passive flexion
White stls - segmentation from MRI. Colored bone stls - progression throughout test (red = initial, green = 1/4 way through test, blue = 1/2 way through test). Colored registration marker stls - spheres from calculated center of digitized points.
