What is the effect of transmission during X-ray interaction with matter?

The effect of transmission during X-ray interaction with matter refers to how X-ray photons interact with tissues and continue to move towards the image receptor. When X-ray photons are produced and directed at a patient, a portion of the photons can pass through the body without any interaction; this is known as transmission. The photons that successfully pass through the tissues without being absorbed or scattered will reach the image receptor—such as a film or digital sensor—and contribute to the formation of the final image.

This process is critical in diagnostic radiography, as it allows for the visualization of internal structures based on the varying levels of attenuation among different tissues. Dense tissues, like bone, will absorb more radiation and appear lighter on the radiograph, while less dense tissues, such as muscle or fat, will allow more photons to pass through and appear darker.

In contrast, other options reflect different interactions that are not classified as transmission. Some photons might lose energy as they interact with matter, resulting in scattering or absorption, or they may be reflected, but this does not contribute to the transmission aspect that is essential for creating a clear and accurate image. Thus, the relationship between transmission and the formation of an image in radiography is fundamental, highlighting the necessity of photons passing entirely through to
