Message-Id: <mailto:199503202203.QAA18922@library.wustl.edu> Date: Mon, 20 Mar 1995 16:56:34 -0500 From: Fred Kwiecien <mailto:kwiecien@UBVMS.CC.BUFFALO.EDU> Subject: digitizing x-rays, again? To: Multiple recipients of list IMAGELIB
I was the original requestor about digitizing x-rays. I want,
first, to thank everyone for some great ideas, and for taking the time to
reply to my plea for help. I cross-posted that original query to VRA,
IMAGELIB, and Photoforum, and I've compiled 27 replies from various folks
who offered advice or had additional questions. If anyone would like me to
e-mail that compilation to them for further perusal, just send me a
request. But please send it to <mailto:kwiecien@ubvms.cc.buffalo.edu> and not
to the whole group!
Let me add just a little bit more about why I was asking about
digital cameras as a possible solution to my problem.
I use RPC currently to make slides from x-rays (or similar
materials). Making a print instead (and then scanning that) wouldn't solve
the problem. Making and scanning a slide is easier for me to do at my
particular shop. But I'd really like to avoid any of that and just scan
directly from the original x-rays.
I don't have direct access to an x-ray scanner of the sort that
some hospitals use, although I have seen one in action. It would be ideal,
but much too expensive. Our volume just can't justify the purchase price.
It's also much too inconvenient to go to a another site that has such a
device, even if we could work out the details of permission and scheduling
when to use it. We really need to have something set up in-house.
The suggestions I've received about using a regular hardcopy
flatbed scanner are more a propos for my situation, because we already have
one of those. However, quality has been an issue when using the flatbed,
as well as not being able to get the bigger films digitized in one shot. I
also don't have a film scanning attachment for it, although some people
have made a case for getting one.
I MIGHT be able to justify getting a good Nikon digital camera
sometime in the near future for doing general digital photography, as we
may have numerous applications for such a device. As such, the purchase of
the camera becomes a better investment than buying a dedicated x-ray
scanner, because it will get used in lots of different ways.
With that in mind, I was wondering if anyone had used such a
digital camera in combination with a copystand and a light box to
photograph transilluminated subjects (specifically x-rays) and what were
your results? I know that I could use a video camera instead, but video
resolution is generally pretty poor. And the Apple QuickTake is not even
in the ballpark.
In any case, thanks for all of the great input so far.
