What is essential for obtaining quality radiographs with minimal patient dose?

Using high kilovoltage peak (kVp) and low milliampere-seconds (mAs) techniques is essential for obtaining quality radiographs while minimizing patient dose. High kVp allows for greater penetration of the X-ray beam, leading to improved image contrast and reducing the amount of exposure needed to achieve a diagnostic quality image. This is particularly effective because higher energy X-ray photons are less likely to be absorbed by the body tissues, resulting in less radiation exposure to the patient.

Conversely, low mAs settings reduce the overall quantity of radiation produced, further decreasing the patient’s dose. The combination of high kVp and low mAs allows radiographers to optimize image quality while protecting patients from unnecessary radiation exposure. This approach aligns with the principles of radiation safety and optimization, which are crucial in radiology practices.
