fluor·o·scope (flr-skp, flôr-)

n.

A device equipped with a fluorescent screen on which the internal structures of an optically opaque object, such as the human body, may be continuously viewed as shadowy images formed by the differential transmission of x-rays through the object.

fluoroscope

an instrument for visual observation of the form and motion of the deep structures of the body by means of x-ray. The patient is put into position so that the part to be viewed is placed between an x-ray tube and a fluorescent screen. The x-rays from the tube pass through the body and project the bones and organs as shadowy images on the screen. Examination by this method is called fluoroscopy, but the image is viewed on a separate television monitor and not on the fluorescent screen. See also image intensification.

The advantage of the fluoroscope is that the action of joints, organs and entire systems of the body can be observed directly. The use of radiopaque media aids in this process. See also barium study.
