Good evening,
I've developed an interest in x-ray sources and imaging techniques. There is a lot of great information out there but I feel there is gaps in my knowledge of the subject.
Below I included a list of questions for anyone to answer. I don't expect one person to answer them all so I numbered them. I also included my thoughts on what prompted these questions for ease of understanding.
Feel free to respond to just one question if you know the answer. Thanks for your time and help guys.
Radiology Questions 3/25/20
1.) Why is the face not prioritized with leaded protection?
I've seen x-ray glasses, caps, gloves and thyroid collars. I'm confused why full face masks are not more widespread considering whats available for other body parts.
2.) Is the chemical makeup of the intensifying/phosphor screens different when comparing the front (tube side) screen to the backside?
Just wondering if both the phosphor screens are identical. If they are identical it would seem the cassette determines which is the tube side. Or maybe the phosphor screens have slightly different composition and that determines the tube side.
3.) Green vs blue film. Why would anyone use blue?
In my experience the rare earth green screens emit so much more light when compared to a blue screen. I'm not sure why anyone would use blue considering the difference. I heard blue has higher resolution, realistically how much better is blues resolution when compared to the resolution of a green screen
4.) Why do we even use x-ray film?
If DR panels have such high resolution and near instant developing time it seems irresponsible to use anything else to diagnose a condition. Not to mention the lower radiation dose to the patient. Unless I'm mistaken the individual components of a DR scanner are not particularly expensive. Yet they seem to cost at least 15k+ when new.
5) I was wondering how different facility handle the removal of old equipment. Is there a specific process you have to follow or are the hospitals selling or donating it.
Curious how different facility's handle the removable of old equipment. Where does it go and who gets it? If a tube goes bad do you just throw it away? or are there specific procedures you have to follow to dispose of it.
6.) How much maintenance are radiologist expected to do on x ray machines?
Do they do things like replace the tube or electronic components of the HV power supply. Or are larger companies handling all the service of the machines?
7.) When you are developing film manually can you develop and fix multiple films at one?
Assuming your using a 8x10 tray that sits flat on a table (not a vertical tank) is it okay to develop two films right on top of each other in the developer/fixer solution.
Thanks for taking the time to read this. I hope you are all health and safe during this time,
Matt
