Here is what I plan to do. My girlfriend is a nurse in a clinic where they do tomograph computer, magnetic resonance and such things. She asked her bosses and they agreed to me going there once when they are less busy and take a few shots. I'm thinking stuff like that can be sold as stock well. The thing is I have to expose myself and the camera to a considerable amount of radiation (on my own risk) I don't worry for myself because I know short time exposures don't do much harm to the human body. I am concerned about the camera tho, anyone knows if digital cameras can take that or not? I mean I wouldn't wanna ruin a perfectly good cam for a few shots that are probably not going to sell for more than 10 bucks :)

If they can go through the airlines, I am sure it will be okay. And the level of rad from (depending on portable, etc.) shouldn't be significant. Doesn't hurt you, probably not the camera. I wouldn't recommend standing in the CT room though. Unless ya protect your thyroid and Baaaaallllllls. (C: I usually stay out of CT unless absolutely have to stay with a pt. And usually get away from the Xrays as much as possible considering the increased exposure I get. I have been told many times by Rads that seven feet from a portable monitor decreases the exposure about 3-5 times (?). even if it is directed it still goes out in a 360 degree arc (not as powerful, though).
I have been thinkiing on increasing medical images, but never have much time to do it. And I really don't want to go in when not schediled or they will want me to work. :P
I've done a couple...
Suture set and Suture set B&W. Some others, like IV's going into an arm, etc...but...
Look on the stock sites for the medical images. Usually involve people in them with equipment, etc.

Thought in mag resonance type facilities you weren't allowed to carry around anything metallic etc ? or is that just in the physics labs that I've been in ?

The concern is that the magentic pull is so strong it can e.g., slice off a finger while it pulls the ring off, or accelerate a coin straight through your body etc...

Or I could be just manufacturing urban myths..

I don't know about those extreme possibilities, but I think that a strong magnetic field may prove anathema to solid state memory media. In other words, you might wipe your camera (Pictures AND firmware) if the field is strong enough.

Had a look - it's called the 'missile effect' A few people have died from it. (very few)

Basically metalic objects get accelerated by the magnet and hit people. Electronic devices like pacemakers are also pretty suceptable - obviously this is all not such an issue if the device is off, but usually for safety reasons, you might not even get to go close with things that are at risk. I know in the lab I visited, everything in the rooms near the magnetic devices had to be non-metallic. (But that was a very high power (3T) magnetic imaging device)

Yeah, I'd avoid MRI because the mag field will mess up memory card and possibly firmware as well. But regular old x-rays shouldn't pose too much of a problem.

Definitely not in MRI! Even when the MRI machine is off there is still a large magnetic field. I know from experience. Had a MD so anxious to get his pt done so he could leave he started pushing the ER cart (lots of metal and O2 tank aboard), tried to get him to stop but he said it isn't on, it won't do nuthin. Well, the bed got sucked right up against the machine (still on it's wheels). It took alot of work to pry that sucker free.
And I have seen the aftermath of an O2 tank in the room when it was going. Not pretty!

Thank you all for the advice, actualy they told me too that it's ok in the CT but not the MRI.
