What factors influence the radiation dose received by a patient during a radiographic exam?

• A. Digital sensor sensitivity and film type
• B. Room temperature and patient anxiety level
• C. Imaging technique, patient size, and number of views obtained
• D. Equipment brand and model

Answer: (C)

The factors that influence the radiation dose received by a patient during a radiographic exam are predominantly related to the imaging technique, patient size, and the number of views obtained. Imaging technique is crucial because it encompasses the settings chosen for the exam, such as kilovoltage (kV), milliamperage (mA), and exposure time. These parameters directly affect the amount of radiation used to produce the image. Patient size plays a significant role as well; larger patients require more radiation to ensure adequate penetration and visualization of structures in the image. This means that the thicker or denser the body part being imaged, the higher the radiation dose that may be necessary. The number of views obtained is also a critical consideration. Each additional view often requires another exposure, thereby increasing the total radiation dose received by the patient. Therefore, minimizing the number of views while still obtaining sufficient diagnostic information is essential in radiographic practice to reduce the overall radiation exposure. While digital sensor sensitivity and film type can impact image quality and may lead to potential dose adjustments, they do not individually dictate the dose received. Room temperature and patient anxiety level do not have a measurable effect on radiation dose. Equipment brand and model may affect performance but are secondary to the factors mentioned
