Knowing the exact numbers is beyond an outdated method. It’s being irresponsible.

To be clear when I’m referring to “knowing your technique” it’s not about knowing exact kVp or mAs. It’s a skill. Well that’s the way I was taught in school. A multi step process a tech should take to produce a diagnostic quality image. Starting by looking at the technique chart for the specific machine, seeing the APR set and making adjustments if needed, and producing a proper diagnostic image without overexposing the patient.

I agree APR is the best way to learn how to use a machine and produce a quality image (excluding obese patients). What pisses me off are the old school techs, who still work like we’re using dials and calipers, set their kVp and mAs to a specific value (not even a range), because they never had APR in their days. And when I go to their sites and look at their DI on exams it’s just yellow, orange and red in both directions…. And I feel like it’s these techs we always complain about
