Radiologic Technologist Practice Exam 2025 – Complete Guide to Test Prep

The term "exposure factors" in radiographic imaging specifically refers to key variables that directly impact both the quality of the resulting images and the amount of radiation that a patient receives during the imaging procedure. This includes measurements such as kilovoltage peak (kVp), which determines the energy and penetrating power of the X-rays produced, and milliampere-seconds (mAs), which controls the quantity of X-rays generated.

By properly adjusting these exposure factors, a radiologic technologist can optimize image contrast, sharpness, and overall diagnostic quality while minimizing the patient's exposure to unnecessary radiation. Understanding and applying these factors is crucial when performing radiographic exams, as they directly affect both the efficacy of the images and patient safety. This knowledge enables technologists to tailor imaging techniques to the specific needs of each examination, ensuring that the benefits of diagnostic imaging outweigh the risks associated with radiation exposure.
