Why do different radiology facilities use different technique standards?

Question

I'm a Rad Tech student and we've been shown one technique in the books, another in the lab and we've been told that we need to learn the techniques for each clinical site we go to.

On top of that, we're expected to make our own technique chart for all the positions we learn.

What's the significance in using different techniques at different facilities?

My guess is the equipment might be stronger/weaker at one place, so you have to make adjustments according to the technological advancement of the equipment.

I know we have to consider patient size, muscular mass, and the condition of the target(ex:emphysema, you would have more air in the lungs, therefore you would lower kVp so the radiograph will not have too much density).

But other than that, why not just stick to a STANDARD?

Answer 1

Well, there are many variables.  The type of film (Kodak vs. AGFA vs. Fuji) will require different techniques, on the same equipment.

Different screens.....different grids.....different developing chemisty.

Learning techniques was very stressful to me, as a RT student.  But, you will figure it out, and you will know how to adjust.  I used a small, purse sized phone book, to write my techniques in.  Under "A", I listed ankle.  Under "K", I listed KUB...you get the idea.  Also, when you are phototiming, watch the read out on the machine to see what MAS was used.  Start writing those down as well.  For example, I usually phototime my lumbar spines, but I recorded those techniques in my little book.  

Best wishes, and good luck!
