    Every once in a while Fidelity Medical Cassettes in 8x10 or 11x14 format show up in various places. Does anyone know whether these are fully equivalent to regular film holders, or say compatible with ANSI standard? Thanks in advance & best regards, Markus

    I purchased two of the 8x10 medical holders off EBay, they were not listed that way and in their original form would not fit an 8x10 back. There are two "ears" on both sides of the holder and I thought I had been stiffed.

    On closer inspection I discovered the ears can be removed. They were attached to the holder by some very small screws, after removal they were in fact regular 8x10 Fidelity holders. I may have been lucky as the ears could be removed - so I would definitely check with the seller before buying.

    In medicine they actually use fidelity film holders! I have picked up seven of it in size 8x10 for a $100 in the other day! They are film holders for photography, so don’t believe anything else! They are feet into any cameras with out any problem!

    So, why they are using it and where?

    There is one examination method called for ultrasound and there is a very low intensity X-ray too!
    In regular X-ray we using intensifying screen also called salted screens and they can be blue or red or neutral! It gives certain speed for x-ray films so exposing time can be reduced as those rays is dangerous for your health! So it’s just because to eliminating risks! But those look totally different so it’s impossible to mistaking its aluminium and when you open it up its white inside!

    Than there is a so called soft X-rays. Now, when using soft X-rays usually film can not be put in any type of intensifier holders as in that case the aluminium would filtrate all X-rays so they using 8x10 holder instead of plastic just to cover the film rather than have in it lying free!

    That’s it guys!
