Hello:
I cannot imagine any harming hazard for X-ray machines and CT
scans.  They are used when studying ingestion of metallic foreign
bodies.
On the other hand, MRI machines (and HGs with metal pieces)
could get seriously damaged.  (That is why neurosurgeons use now Titanium
clips instead of steel ones).

I think the problem is more with machines that are hired or rented (like
many photocopy machines) or where there are the usual warranty problems of
using something for other than the purpose for which it is intended.
(A bit like making your coffee in the sterilizing box).
Due to the cost of the machines, I can see many people (especially if they
don't own them themselves) being very worried at popping a HG under one.
Most insurances wouldn't cover any possible damage (dropping the HG from a
great height onto the machine) and it would take a brave technician to do
the deed knowing they would probably get fired if found out.I like the idea
of a vet though. That sounds good.If they can X-Ray King Tut, a HG seems a
doddle.

X-Rays. Was Re: [HG] Binding shaft on Reichmann hurdy-gurdy

2007-06-11 Thread Arle Lommel

Alden,

How do you get X-rays? A number of years back I approached a fellow I  
knew who worked at a major medical imaging manufacturer, who told me  
in no uncertain terms that if any medical equipment were ever used  
for such a purpose, it would invalidate all sorts of agreements and  
be against the law. I found that hard to believe, but he was  
insistent that there is no way he could ever help me get the image I  
wanted or that his equipment would be worthless after that.

How do you get X-rays? 

Try a museum.  Some have x-ray equipment or access to it.  When I lived in 
Pensacola, Florida I worked as a volunteer on some finds dredged up from a ship 
that sank in the bay in 1559. Some of the extremely corroded finds were x-rayed 
and/or cat scanned by one of the local hospitals. At least for the ones I saw, 
the equipment was temporarily re-located to the conservation facility. 
Obviously they weren't worried about any warranties being invalidated, and they 
enjoyed the publicity.

I have a friend who is a veterinarian, who does x-rays of old stuff for me all 
the time, without ever harming the equipment or invalidating and warranty or 
such.  Of course the clinic owns the x-ray machine, and I usually get the 
images after hours.  I don't know what it would cost - I always take the 
service out in trade (even cleaning around the clinic, if necessary)

My advice - don't try people doctors, they are all bound up in all sorts of 
industry red tape.  Find a vet, they are more likely to be helpful.

I know that to be wrong because there are all sorts of industrial X-ray
processes used from small items to concrete blocks and oil pipes. He may,
however, be right in that medical machines should not be used in that way.
You need to look for industrial companies, not medical.The safety rules are
different and, probably, the strength of the rays. (Google industrial X
ray).
A university would be a good place to start.

Thanks everyone,

I figured that a HG couldn't possibly harm an X-ray machine. I don't  
know why the fellow told me what he did, especially as he was  
generally very helpful and friendly. I found his response strange,  
but figured he must know something I didn't

We get our X-rays sort of under the table (so to speak) from a clinic where a
friend of a friend is the director of radiology.  (Convenient, that.)   She
didn't seem at all concerned about the insurance implications or whatever. 
The techs are always very helpful and interested (pecan brownies help here),
but I do typically need to bring in my stuff after hours so as not to
interfere with patient bookings.

We've even gotten some CT scans of instruments - fabulous for showing the
exact positions and shapes of braces, the shape of the lute back, and other
cool stuff.  CT scans do have some shadowing issues with metal pieces - the
shaft always looks like the sun's corona during an eclipse, and other metal
parts give weird effects, but it's more a matter of interpretation than of
harming the machine.

It may be that the guy had just been razzed by an insurance inspector or
something and didn't want to deal with the hassle.
