mAs = Dose

Today’s post will center on how the mAs you use is directly proportional to the dose you are giving your patients.  I could have just written “the dose the patient is getting” but I really want to make it clear that you the radiographer, or radiographer student, are the one setting

How Low Can You Go?

This is how I teach ALARA (As Low As Reasonably Achievable) to all of my students and whenever I give any kind of talk on digital radiography techniques to students or techs.  It’s all about using the smallest/lowest mAs possible so that the dose is as low as it can

How Much Off-Focus Radiation Comes Out of the Tube?

Today’s blog is about off-focus (stem) radiation which until a couple of weeks ago I had completely forgotten about.  As a reminder to all of you who haven’t cracked open your physics books in a while; off-focus radiation are x-rays produced by stray electrons that interact at positions on the anode

Universal CR & DR Technique Charts

Back in the film days I would always give my students a technique chart that had about 50 different body parts on it.  When we went digital in 2002, our vendor told to use the same techniques, so we continued to use those charts.  Four years later we had learned

Off-Focus Radiation

This whole project began when we tried to prove if a patient should be shielded in the front or the back for a PA chest x-ray. I decided to test this out using an 8×10 CR cassette that I would run at 1200 speed, making it extremely sensitive to any
