What parameters can enhance image contrast in radiography?

Enhancing image contrast in radiography is crucial for obtaining clear and interpretable results. The correct answer focuses on the effects of kilovolt peak (kVp) and filtration on image quality.

kVp essentially controls the energy of the X-ray beam. Higher kVp settings increase the penetrating power of the X-rays, which can affect the contrast in images. While higher energy can improve the ability to penetrate denser materials, it can also lead to decreased contrast in the image, as the beam can pass through both dense and less dense materials more uniformly. Therefore, adjusting kVp carefully is vital for maximizing contrast based on the specific requirements of the examination.

Filtration improves image quality by selectively reducing low-energy X-rays that contribute little to the image quality while allowing higher-energy X-rays, which provide better contrast, to pass through. This reduction of scatter radiation helps enhance image contrast, making important details clearer.

While other factors, such as exposure time, temperature, humidity, and type of film stock, can affect image quality, they do not play as direct a role in enhancing image contrast as kVp and filtration do. For example, exposure time primarily influences the overall density of the radiographic image rather than the contrast between different materials. Temperature and humidity
