One tissue donor can enhance or save the life of … WebA special tube inside the x-ray machine sends out a controlled beam of radiation. Tissues in the body absorb or block the radiation to varying degrees. Dense tissues such as bones block most radiation, but soft tissues, like fat or muscle, block less. After passing through the body, the beam hits a piece of film or a special detector.
WebIn a neck X-ray, an X-ray machine sends a beam of radiation through the neck, and an image is recorded on a computer or special film. This image can show: the vertebrae (neck bones) the soft tissue in front of the vertebrae. the adenoids and tonsils if they're enlarged. the oral and nasal airways and the nasopharynx (where those two airways meet) WebWikipedia
WebDec 14, 2024 · As the high-energy photons pass through material, their energy is decreasing. This is known as attenuation. The attenuation theory is valid for X-rays and gamma rays as well. It turns out that higher energy photons (hard X-rays) travel through tissue more easily than low-energy photons (i.e. the higher energy photons are less likely to interact ...
