In a radiographic procedure, which factor is adjusted to enhance image penetration?

In a radiographic procedure, adjusting kVp (kilovoltage peak) is crucial for enhancing image penetration. KVp determines the quality and energy of the X-ray beam. Higher kVp settings increase the energy of the X-rays, allowing them to penetrate denser tissues and materials more effectively. This results in improved image contrast and detail, especially in areas of the body with varying tissue densities, such as the lungs or bones.

When the kVp is increased, more X-rays reach the film or detector, providing a clearer image of the structures being examined. This adjustment is particularly important for imaging thicker body parts or when using contrast media, as it helps to differentiate between types of tissues by providing enough penetration to visualize them correctly.

In contrast, mA (milliamperage) primarily affects the quantity of X-rays produced, which influences image darkness or density rather than penetration quality. Film speed relates to the sensitivity of the film to radiation, and distance affects the intensity of the X-ray beam but does not specifically enhance penetration as effectively as kVp adjustments do.
