  • Summary: 3-D Shoulder Models Constructed from 2-D MRI Segments

    Here are the responses that I got from my post about 3-D shoulder
    remodeling from 2-D MRI Images - not an overwhelming response, however
    a good start nonetheless. In continuing research, if anyone happens
    to come across any information or produce something on their own
    relevant to this topic, please don't hesitate to contact me.

    Thanks to all those who wrote back.

    I do know that Bart Kaptein of the Dutch Shoulder Group did this
    dissertation: Towards in vivo parameter estimation for a
    musculoskeletal model of the human shoulder.

    It relied heavily on MRI to reconstruct shoulder structures.

    Dear Sarah,

    We have a database with a lot of medical imaging data. We could
    provide some services. If you are interested, we can deliver you
    shoulder (bony) images, like the ones attached for example.

    What file format would you need?

    Hie Sarah,
    we have some data-images on the gleno-humeral geometry (surfaces only
    from digitizer) but I don't know which kind of format you need or
    what's you application and therefore I don't know if they could be
    useful to you.

    Bye, Sandra

    Dear Sarah,

    I could provide a 3D model of the shoulder, based on CT images.
    However, not certain why you need MRI images? If you want the bone
    structures, then you would normally use CTs.

    Let me know what is the file format you require. STL is fine?

    We would appreciate if you could just provide some acknowledgment at
    any papers, conferences etc.

    Look forward to hearing from you,

    Best regards,

    Hi there,

    I am a student in my final year of mechanical engineering at the
    University of Western Australia.

    I was forwarded your query by my supervisor. I am involved with the
    Finite element modelling of the shoulder. We obtained a 2D CT-Scan of
    a patient and imported the data into MIMICS, a medical imaging
    software. The model is then converted to a 3D stereolithograph which
    can be manipulated within Solid Edge and then imported into ANSYS, the
    FEA program, where bc's and loads can be applied.

    I was quite successful in the process and am happy to help out, please
    indicate what exactly your questions are.

    Cheers

    Subajan
