In fluoroscopy, what is used to visualize real-time patient images?

In fluoroscopy, a fluoroscope is the essential equipment used to visualize real-time images of a patient's internal structures. The fluoroscope employs an X-ray tube and a fluorescent screen or flat-panel detector to capture continuous X-ray images as they are produced. This allows healthcare professionals to observe movement within the body, such as the motion of organs or the flow of contrast agents, providing vital information for diagnosis and treatment.

The fluoroscopic technique stands out because it enables dynamic imaging, unlike static imaging methods typically used in CT scans or standard X-ray setups. The ability to view images in motion is crucial for certain medical examinations and procedures, such as evaluating gastrointestinal function or guiding interventional procedures.
