What is the primary purpose of using high kVp and low mAs in fluoroscopy?

The primary purpose of using high kilovoltage peak (kVp) and low milliampere-seconds (mAs) in fluoroscopy is to minimize radiation exposure. High kVp settings allow for a more penetrating x-ray beam, which reduces the amount of radiation needed to visualize the internal structures clearly. Because the higher energy photons can pass through body tissues with greater efficiency, this approach helps maintain adequate image quality while significantly reducing the total radiation dose to the patient.

Additionally, low mAs further decreases the quantity of x-rays produced, further ensuring minimal exposure. This methodology is vital in clinical practice, especially in procedures like fluoroscopy, where continuous imaging could lead to heightened cumulative radiation exposure. By using high kVp and low mAs, healthcare professionals can optimize safety for both patients and staff involved in the imaging procedures.
