Converting CT or MRI scan data into an STL file


Respected sir,

Myself and three of my colleagues are very much interested in developing an interfacing software which takes in the CT/MRI scanning data and convert it into an STL file..

The present problem we face is that we are not able to get an example of the CT/ MRI scan data and hence, we don’t know what format they are in exactly. The WIPRO GE medical systems here in India (manufacturers of scanning machines) aren’t aware of these data types as they just import from some foreign country where their head office is located.

It would be very much useful if you could kindly help us with the scan data and brief us about how to go about our task. We are literally asking for your guidance so that we could reach a level from where we could go by ourselves.

Eagerly looking forward to your mail to get shape to our dreams!

Thanking you.

Yours faithfully,
CP



Dear Mr. / Ms. CP:

I would suggest several things. First, is that this problem has been worked on many times by both commercial software providers and university researchers and is at a high state of development. You should always try to find out what has been done before you begin so that you won't waste your time.

  1. Look on our web site under the "Software" listings for packages which translate CT and other medical formats to STL. There are quite a number. Visit the companies web sites which will discuss what file formats are available for translation. Then you can search for the definitions of those formats fairly easily on the web. You might also contact those companies which are often willing to help students.

  2. Check our bibliography (Mom) and you will find numerous papers on the subject which discuss both specialized and commercial applications in this area. Note that we don't supply papers, but there is a page on the site that gives you ideas for finding them. Of course, from these papers you will also be able to find out more about likely places to uncover more information. The University of Zurich has a group which is very versed in the area (among many others) and they might help you.

  3. Post your needs to the RP Mailing List. (See the page for information sources on our site.) Someone on the list will know exactly what you need, I'm sure, but since this question has been asked several times, I believe, you may not get an answer. Download the last couple of years of postings from our site and scan them for pertinent information about this.

That ought to get you going and I hope you find this a help.
