Shooting HPX170...P2 Only...in magnetic fields?

[freelanzr]

Hey all...I have a shoot coming up and I wanted to see if anyone had experience shooting P2 only in magnetic fields like those that would be produced by an MRI scanner?

I have a new client that for the most part the machines will be shut off but a few of them will not allow to be shot while off.

Just want to be prepared...if I have to stay back say 6 feet or whatever.

I know magnetic fields used to scramble a beta camera, but that was mainly because it had to right to tape.

Thanks for any guidance or tips.

Hello all...a lot views here, but no replies...so I will share what I have found out so far.


Some info that I got from a guy at I believe it was Johns Hopkins Radiology Department via Creative Cow...some of this I already knew from having shot in cath labs and the like, but good info nonetheless:

The most important thing to remember about MRI is that the magnet is always on. The tech assisting you may not even let you into the room where the MRI scanner is, but if he/she does, don't take anything metallic with you, or you may lose it. Don't take your wallet or credit cards in the room because they may be erased. You won't be able to light the MRI scanner because the magnet will drag the light across the floor and they will have to take the scanner out of service until a repair technician can pry the light out of the scanner. I've seen pictures of a walker jammed in one and it was enough to convince me.

As for the camera, you probably won't be able to see a picture once you stand on the threshold of the room where the scanner is. Getting the camera within six or seven feet will most likely erase all the data on the cards and the firmware--everything, assuming you can even hold the camera that close. In other words, don't try to bring your camera in the room with the scanner. Shoot through the open door as the patient gets situated and through the glass where the tech sits & operates the scan.

CT scans are like most X-rays and flouroscopy. You can be in the room with the scanner while it is scanning the patient, but you should be wearing a lead apron. It won't hurt your camera if you want to lock it down and leave the room during the scan. Like the MRI, you can shoot through the glass pretty well, but unlike the MRI you can light the room all you want.

Ultrasound, bone density scan (Dexa), are easy and no special precautions are necessary for you or the camera. PET scans have the same precautions as CT, though the patient is mildly radioactive!

You didn't mention it, but if you happen to shoot radiation therapy like for a cancer patient, you won't be in the treatment room during the treatment, but you probably don't want to leave your camera in there whenever the beam is on. They put cameras in all the treatment rooms for the tech to monitor the patient and all the cameras I've seen have dozens of dead pixels for some reason.
