I found it; here's the site...
http://www.crd.ge.com/esl/cgsp/projects/vm/
It's called the "Visible Human" project. (I need to re-familiarize myself with
the details, to see if any of my suggestions are worthwhile.)

I was investigating this:
http://fly.mpi-cbg.de/~saalfeld/df3.html
for other purposes (clouds) but got diverted onto something else and never
made much progress, so all I can offer is that above link .... perhaps
someone else can have a look

I am interested enough to see what you need. If I thought I could add
value and meet your deadlines I would do some work.

i think there are people interested, unfortunately i just got pov dont know
how to use it very well,

Dear all,
Thank you very much for your replies. Jim thanks for your offer.
Given the interest, I would like to be more specific about the elements
required.
We do not need a full 3d model, especially not one that can be rotated. We need
a schematic picture only and we therefore only need to include anatomical
landmarks. If you are interested, have a look at the following link please:
http://www.merckmedicus.com/ppdocs/us/hcp/content/emed/Nervous/Brain_JPEGs/index.htm
If you look at the cross section on the slightly rotated picture, that is
already too detailed, but approximately what we are looking for.
In terms of anatomical detail, the illustration needs to identify the brain
hemispheres, the ventricles, the major blood vessels. It would be nice to put
this all into a schematic human head with schematic facial features and to
illustrate it using layer of section with partial transparency. I have the
picture in my head and I would be happy to draw it, scan it and post it as a
jpg to make things easier.
Regarding the motivation for this: I understand that a non-profit contribution
is not exactly tempting.
Personally, I do not get any salary for this project either, but the problem
that we are discussing is very relevant. Traumatic Brain Injury is one of the
leading causes of death and disability in young patients, particularly after
road traffic accidents. There are no pharmacological treatments available to
protect the brain function during recovery, however, there are multiple
scientific hypotheses of how this could be achieved. In order to proof or
refute these hypotheses the processes in patients need to be understood more
completely. Already, intensive care medicine is making use of a number of
techniques to monitor brain function after injury. Small tubes are placed in
the blood vessels and fluid filled spaces in the brain and we are also using
sequential imaging methods to get an idea of the time course of injury. The
picture discussed would illustrate those methods. Our hypothesis is that these
monitoring devices can be used to not only guide patient treatment, but to
extract data for a better understanding of the disease processes and treatment
options.
The publication will hopefully make a significant impact on this field of
medicine.
If you are still interested, please let me know your email address and I can
send a few drafts of the illustration. We can then discuss things further.
My email address is: tj212 (at) cam.ac.uk

I feel this is a very worthy topic and I hope you get the support you need.
FYI there is another occasional visitor to these newsgroups, Andrel Linnenbank
of the University of Amsterdam, who I know uses POV for scientific illustration:
he does cardiac research and has published a number of papers with POV images.
He may be able to give you some tips.

While I hope they will find someone to do the work, i hope we will not see
the result as a wonderful illustration in some expensive book...
That happened to me some time ago, ha ha ha! So I got my experience in that
field.
But if there's no financial earning behind it, then - why not? In fact, I
would consider it a good idea to publish that 3D model as object inside the
POV-Ray object library.

Thanks again for all the different views and opinions. Sven, I am sorry to read
about your bad experience in the past.
Jim has kindly offered to look into our request more closely. We will not use
this message board further. Please contact me via email should you wish to.
If in future the result should be part of any publication, we will post the
link.

In fact, it is not wrong but the best you can do to use message boards like
this. The responses usually have a broad bandwidth of feedbacks, it is
always good to expect that.
While some might be critically, it still makes sense to use message boards
like this. Don't feel demotivated. :-)
POV-Ray is a wonderful tool to achieve detailed 3D views, and offers a lot
of amazing features.
Greetings,
Sven

The deliverables required for the project are illustrations not models,
and not necessarily even renders. However, the approach that I have
promoted to Tobias, and believe to be the most flexible and efficient,
is, in fact, to make a simple mesh model of the needed brain anatomy and
then to render the necessary illustrations in POV from the model. This
approach would most easily create advantageous cutaways, camera views
and so on, facilitate sequences of related images, and support updates
and tweaking of related images. The final result will almost certainly
involve image editing too. But if all goes well, I believe the mesh
model we use could find a home in the object library, yes.
