WebDescribing X-ray abnormalities in terms of density may help in determining the tissue involved. A radiographic image is composed of a 'map' of X-rays that have either passed freely through the body or have been variably attenuated (absorbed or scattered) by anatomical structures. The denser the tissue, the more X-rays are attenuated. WebDense bone absorbs much of the radiation while soft tissue (muscle, fat, and organs) allow more of the x-rays to pass through them. As a result, bones appear white on the x-ray, soft tissue shows up in shades of gray, and air appears black. Most x-ray images are electronically stored digital files.

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. WebICG has undergone a resurgence of use in recent years primarily for tissue perfusion assessment 7,10,11 but also for tissue identification and soft-tissue infection management 12.

Diagnostic … WebX-ray beam attenuation. As the x-ray beam passes through tissue, photons get absorbed so there is less energy; this is known as attenuation. It turns out that higher energy photons travel through tissue more easily than low-energy photons (i.e. the higher energy photons are less likely to interact with matter).
