Hi Sir
I have a query regarding the bones available in the anybody human model. I want to export loads on the fibula bone. But there is no fibula bone in the anybody human model.How can i generate fibula bone from anybody human model?
Thanks.

Hi Mohit,

Unfortunately we do not have the fibula in this dataset. It was derived from a cadaveric study by Klein-Horsman, which did not have very good medical images to segment it from. In some future we will add another dataset, which will contain better geometry and will contain fibula, but I can’t tell the dates yet.

I think for now the only option is to morph a fibula from another dataset into the AnyBody one:

  1. Find a tibial geometry with fibula (let’s call it A)
  2. Construct landmarks for both tibia and fibula (you could use muscle attachments that are present in the AnyBody dataset (B))
  3. Construct a non-linear RBF transformation from A to B
  4. Apply it to the fibula of A
  5. Export the result as fibula of B

Another problem will be that the shank segment contains all muscle attachment nodes of fibula - you would need to separate/filter needed muscle branches to be applied to the fibula. Please use ForceObjectExclude and ForceObjectList members of AnyMechOutputFileForceExport to do so. The tip would be to search the forum for ObjSearch and ObjSearchRecursive that will give you an idea how to filter force list.

Please start with the first part.

Kind regards,
Pavel
