Re[2]: Angiogram Dose

[coogen_michael@hq2ccgw.hq.dla.mil]

The radio opague dye is non-radioactive.  In order to calcuate the dose that 
your patient received you need to determine the output (mR/mAs) of the x-ray 
machine.  Once you determine the output, then you need to determine how much 
exposure time was given to your patient..mike coogen sends

* Hello all,
* 
* One of my workers recently received an angiogram.  A small tube was 
* threaded up through a small incision in his leg to the heart region, a 
* radio-opaque die was injected into his blood stream, and "lots" of 
* x-rays taken.  I checked my standard references and found nothing 
* discussing the doses involved.
* 
* Does anyone know how much dose he is likely to have received? 
*

* Thanks,

The dose the the patient will vary greatly according to the type of imaging 
equipment used and the manner in which it is employed.  
Saying that, there have been a few paprs puplished:
Mustafa AA and Janeczek J  BJR (1989) 62 pp 838 - 842 used a phantom to 
measure organ doses.

I'm trying to find the patient studies which I know we have copies of.
