5 Reasons One Would Change a Technique

There are only 5 reasons why a radiographer would change a technique (and 8 ways you could do it without using distance).  As the how’s are not nearly as interesting as the whys, we’ll start with why you would change a given technique.  Here are the 5 reasons: Increase kV,

The Difference in Lead Apron Thickness

A few years ago I was in charge of choosing and purchasing the lead aprons used in our radiology department. We had one main vendor we used so I contacted them about getting a bunch of front sided and wrap around aprons as well as half shields of different sizes.

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

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

Optimum kV for DR & CR Equipment

As soon as the film-screen combination was developed in our profession, there has been optimum kVs used for every body part.  Even when Rare Earth screens came on the market in the early 80’s and the mAs was cut to one third (from 9 to 3 for example) the kV

How to Properly Critique a Digital Image

We have had hundreds of digital equipment training hours at my hospital in the past 10 years, but in all of that I don’t remember any time given in learning how to correctly critique the image.  I have to imagine this is the same with everyone around the country, possibly
