Radiolucent
Radiolucent (ray-dee-oh-loo-sent) is a term used in radiology to describe a substance or body part that allows the passage of X-rays or other forms of radiation. It is derived from the Latin words 'radius' meaning ray, and 'lucent' meaning light.
Definition
Radiolucent materials appear dark on radiographic images because they allow radiation to pass through, rather than absorbing it. This is in contrast to radiopaque materials, which appear white or light because they absorb or block radiation.
Applications
In the field of medicine, radiolucent materials are often used in medical devices such as catheters and surgical instruments to allow for clear imaging during procedures. They are also used in the construction of radiology equipment to prevent interference with imaging.
