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.

Adrian Liggins, Ph.D.
Rita Patterson, Ph.D.

Norman Murphy, Ph.D.
