What is the primary effect of X-rays in medical imaging?

The primary effect of X-rays in medical imaging is that they permeate human flesh to expose film. This capability arises from the nature of X-ray radiation, which is a form of high-energy electromagnetic radiation. X-rays can pass through various tissues of the body because they have sufficient energy to penetrate soft tissues, while being absorbed more by denser structures such as bones. When X-rays interact with the photographic film or digital sensors used in imaging, they create an image based on the varying degrees of absorption across different tissues.

This fundamental property is integral to how X-ray imaging works, as it enables healthcare professionals to visualize the internal structures of the body, identify fractures, diagnose diseases, and monitor the progression of medical conditions. The clarity and contrast of the images produced depend not only on the type of tissue but also on the X-ray technique used.
