[sci.med] Digitized Radiographs, MRI scans wanted for Macintosh demo

bmartin@uhccux.uhcc.hawaii.edu (Brian Martin) (09/29/89)

Hello,

I'm trying to help people here at the medical school understand some of
the capabilities of the Macintosh. While several of the deans own SEs,
and the dean has suggested that he'd like to see every medical student
own a macintosh, the majority of people here own IBMs or compatibles.

If anyone has access to directly-scanned radiographs, CT-scans, or MRI
scans, especially ones demonstrating pathology, please contact me.
We've scanned x-rays, angiograms and CT-scans published in textbooks,
but the resolution is not detailed enough for our purposes.  We'd like
to show how one can directly manipulate brightness and contrast
on-screen with a program such as ImageStudio, to demonstrate/enhance
subtle density gradations. We'd also like to demonstrate how color
mapping or the application of certain convolutions could enhance these
images, especially for the non-radiologist.  I can ftp it from your
site, or I could send diskettes to you.

Thanks in advance,
-- Brian

You want to get hold of a copy of the public domain NIH-Image program if
you are considering using the Mac to look at radiographs, CT scans, MRI
scans, etc. It lets you directly minipulate brightness and contrast,
and also supports pseudocolor. it is available via ftp from sumex-aim
and now directly from NIH at alw.nih.gov in /pub/ftp/image. The NIH
site also has example MRI and CT scans.
