fluoroscope

(flo͝or`əskōp), instrument consisting of an X-ray machine (see X rayX ray,
invisible, highly penetrating electromagnetic radiation of much shorter wavelength (higher frequency) than visible light. The wavelength range for X rays is from about 10−8 m to about 10−11

) and a fluorescent screen that may be used by physicians to view the internal organs of the body. During medical diagnosis the patient stands between the X-ray machine, or other radiation source, and the fluorescent screen. Radiation passes through the body, producing varying degrees of light and shadow on the screen. Although the regular X-ray photograph shows more detail, fluoroscopy is preferable when the physician wants to see the live image, i.e., observe the size, shape, and movement of the patient's internal organs. In industry the fluoroscope is used for the examination of materials, manufactured objects, welds, castings, and other objects, principally for flaws.

fluoroscope

[′flu̇r·ə‚skōp]
(engineering)
A fluorescent screen designed for use with an x-ray tube to permit direct visual observation of x-ray shadow images of objects interposed between the x-ray tube and the screen.

(22) Another method of maximizing distance from the x-ray source is through proper positioning of the fluoroscope. By positioning the smaller x-ray source above the patient and the larger image intensifier below, there is a larger field for easier positioning of the extremity and reduced need for repeat images.

Due to the previous anastomosis (Figure 1(a)), the afferent loop and efferent loop of patients were distinguished through the following methods: (1) reviewing the previous surgery records: if the large curve was proximal for patients in the left-lateral supine position, the inferior orifice indicated the afferent loop; and vice versa; (2) observing the intestinal cavity: it is easier for the scope to enter the efferent loop and the afferent loop usually has bubbles and bile; and (3) using the C-arm fluoroscope: the path of the endoscope can be visualized under fluoroscopic guidance.
