Preparing for the Test
We have our first Radiographic Imaging (RAD-121) test in the morning. So far, this class hasn’t been much more than a review of topics we covered in Patient Care & Intro to Radiography (RAD-111) during the first semester. The first segment of this test covers visual perception topics such as boundary effect, mach effect, threshold detection, and simple optical anatomy. The next section will be covering topics such as x-ray tube contstruction, functions and construction of the tube parts, the process of x-ray creation, types of radiation, mAs, kVp, and properties of x-rays. Most of this second section is review. There isn’t much new information at all here. The third section revisits mAs, kVp, and SID with reintroduction of the mAs formula, mAs reciprocity, intensity/mAs relationships, intensity/kVp relationships, the inverse square law, and a host of problems solved with all those formulas. The final section gets into some new material that I posted about yesterday. The photoelectric and compton effects, as well as attenuation. The material isn’t as complicated as it sounds, and I’m hoping I’ll do well on the test tomorrow. The difficult part about tests from this instructor is that a lot of his questions are designed to be confusing, and it takes a good bit of concentration and attention to detail during the test to keep from overlooking things. There are a few minor details I still need to look over, but they are minor. I hope I’m ready because I think I’m about finished studying for this one…
