The 15% Rule-Simplified
Understand the physics. Control the exposure. Pass the ARRT Registry.
Service Description
The 15% rule is one of the most tested imaging physics concepts on the ARRT Radiography Registry — and one of the most misunderstood. In this interactive study group, we simplify the math and explain why receptor exposure doubles when kVp increases by 15%. Students will practice: Calculating 15% kVp increases and decreases Identifying how exposure differs from mAs Determining new mAs values to maintain exposure This session is ideal for radiologic technologist students who are uncomfortable with exposure maintenance formulas and need structured, guided practice.
