In X-ray imaging, "contrast" refers to the difference in density between various structures in the image. High contrast allows for clear differentiation between different tissues or structures, making it easier to identify and diagnose abnormalities.
Motion blur occurs when the patient moves during the X-ray exposure, resulting in a blurred image. This artifact can affect the clarity of the image and may require retaking the X-ray to obtain a clearer diagnostic result.
Quantum mottle, or noise, refers to the uneven distribution of X-ray photons reaching the detector, leading to a grainy appearance in the image. It often results from insufficient X-ray exposure and can affect the diagnostic quality of the image.
Increasing the kVp setting increases the energy and penetration of the X-ray beam, which results in decreased image contrast but better penetration through dense structures. This is useful for imaging thicker body parts or structures.
Inadequate detail or blurring in an X-ray image often results from improper patient positioning or movement. Ensuring the patient is correctly positioned and remains still during the exposure helps achieve a clearer and more detailed image.
