  • responses to Fuji film

    Hello to Everyone,

    In late May I posted an inquiry regarding the use of Fuji film in an animal
    model, with particular reference to the rabbit. This inquiry actually
    covered a wide range of questions regarding the use of Fuji film and its
    application to orthopedics. The response was excellent in providing
    information about shareware image analysis packages and the previous
    literature on this research subject.

    A quick summary of my questions:

    QUESTION 1: What methodologies give meaningful and repeatable results?
    QUESTION 2: Is/are there publication/s that describe that methodology?
    QUESTION 3: Is anyone familiar with the Bristol group?
    QUESTION 4: Does a shareware image analysis package exist?
    QUESTION 5: Are there problems storing the films for long periods of time?
    QUESTION 6: Can films be stacked up one another?
    QUESTION 7: Are there problems when using the films in certain fluids?

    The responses to Q1-3 and 5-7 were excellent in citing particular research
    papers and facilities that perform this type of research. All papers listed
    by individual respondents were also cited on the web page created by Adrian
    Liggins, Ph.D., which is dedicated to research using pressure sensitive
    film. I highly encourage anyone interested in learning more about this
    research area to visit the site. The site contains information on both the
    technical side of Fuji film (resolution/image analysis) and the orthopedic
    application of this material. The site location:

    The responses to Q4 demonstrated that about half the people using shareware
    image analysis packages used NIH Image while the other half used Osiris.
    Both groups described previous technical problems with these packages.
    However, recent improvements have apparently fixed any preliminary

    An alternative source for in vivo or in vitro pressure measurements came
    from TekScan. This group makes a pressure sensitive mat which can be placed
    in the joint space. However, since Fuji film was already in use, further
    inquires into the suitability of the TekScan technology was not pursued.

    I certainly appreciate the assistance of all respondents, some of whom wish
    not to be listed here. Should any other information be passed along to me,
    I will update this posting with that information.

    Again, thanks to the following people.
