What type of imaging is used by X-ray machines?

X-ray machines utilize ionizing radiation to create images of the internal structures of the body. This process involves emitting X-rays, which penetrate tissues and organs at different rates; denser materials like bones absorb more X-rays, resulting in a lighter area on the resulting image. In contrast, softer tissues allow more X-rays to pass through, creating darker areas. This differential absorption is what enables X-ray imaging to provide clear visuals of structures such as bones, organs, and certain diseases.

The other imaging types mentioned do not apply to X-ray machines. Sound wave imaging relates to ultrasound technology, which uses high-frequency sound waves rather than ionizing radiation to produce images. Magnetic resonance imaging (MRI) relies on magnetic fields and radio waves to visualize internal tissues, while infrared photography uses infrared light and is not suitable for internal imaging in a diagnostic context. Thus, the method that X-ray machines use is indeed ionizing radiation to create images, validating the choice.
