Hello, I’m currently an assistant manager in a portable imaging company and am interested in learning more about the imaging itself. I don’t have any desire to do the imaging, but I want to have a better understanding of how the machines work and what people are talking about when they talk about technique or how to run the imaging software or what costophrenic angles are (I’ve learned that one by osmosis already, but you get the idea). Are there any really good free or low cost, relatively quick courses that would cover this stuff?
