Röntgen is a German term that refers to the process of using X-rays to capture images of internal bodily structures, such as bones and organs. In English, the term is often used interchangeably with X-ray. However, there are a few synonyms for the term röntgen, including radiography, radiology, and roentgenography. Radiography refers to the process of taking X-rays, while radiology refers to the study and interpretation of X-rays. Roentgenography is similar to röntgen, as it refers specifically to the use of X-rays to capture images of the body. Despite the different terms, they all refer to the same basic concept of using X-rays to capture images of internal bodily structures.
