Re: pls suggest me

One of the projects I started a while ago really needs to be looked at for
cleaning up and maybe made commercial. I have a working system that I use,
but the software is clunky and completely undocumented making it useless for
anyone but me.

As more and more equipment goes hi-tech, the tools that go with it need to
grow as well. I maintain and repair imaging equipment including X-Ray, CT,
MRI, Ultrasound and nuclear medicine. Diagnostic and quality control tends
to be unique and proprietary for each machine (even within the same
manufacturer.) In addition test results can be very subjective, example:
"Does the picture of the phantom look good? One ultrasound many actually
says that in the diagnostic section.

What I have done is to take a laptop computer and added a video capture
capability to it and software based upon Microsoft Access to capture and
store diagnostic images. I have also written a package that lets me
manipulate the images in some specific ways:

1) "strip" mode - shows a series of diagnostic images as frame in a movie
format. It also does scaling and alignment automatically so that any
changes in focus, resolution or view can be readily spotted;

2) Real time overlay - playback an image from the database and place a
real-time image from the device over it to allow for replication of phantom
or target position;

Not all equipment has a have a raw video output, so I attach directly to the
analog or digital info going directly to the monitor. Because of the large
differences in scan rates and signals I actually a series of acquisition
products I use. These need to be cleaned up and a single "black" box"
built. The black box would be "smart" and could sense video type, rate and
other information required to setup acquisition parameters.

One done, this product could also be used to capture test, PM / quality
control and performance data on imagine systems, patient monitors.
defibrillators or any other system that uses a monitor or screen for display
(what systems don't). This would not only be useful for technicians but
from a risk management view it allows for quantifiable proof that a given
system was properly functioning. Remember that these days, PM is almost
more about CYA than actually maintaining the equipment.

I won't give away my code - you would need to do that your self. The images
are stored using a Access database that also stores setup parameters and
test configuration data so I don't need any hardcopy forms while diagnosing
the machines.

The black box for video acquisition could be easily be built on VXI or
extended PCI using largely off the self hardware. I would potbelly do this
based on an Intel process based SBC and a 802.11G interface to keep it
simple. I used some Matrox video cards for acquisition. The are fast,
flexible ad handle a large range of video inputs. The currently "black" box
is a Compaq pizza box computer running Linux with three different Matrox
video acquisition cards built in. It talks to the laptop via USB. I would
not recommend USB for this as it is a little slow - but - very easily to
implement.

Anyway, I have moved on to other paying projects and this thing stalled
about 1 year ago. I don't mind giving away the idea or any help I can
offer. Maybe this will give you an idea or 2. Let me know (direct or
posted) what project you decide to take on). At the local school, they let
our biomedical engineering students get away with very simple projects.
This one would certainly not falls in this category. Good Luck,

Don
