What does fluoroscopy utilize to create real-time imaging?

Fluoroscopy is a medical imaging technique that utilizes X-rays to produce real-time images of the movement of internal structures and fluids within the body. Unlike traditional X-ray imaging, which captures static images, fluoroscopy provides continuous imaging, allowing healthcare providers to observe processes such as swallowing, the motion of joints, or the functioning of organs in real-time.

The use of X-rays in fluoroscopy is essential because they penetrate body tissues and can create images on a screen, facilitating the observation of dynamic processes. This capability is invaluable in various medical procedures, including gastrointestinal studies, catheter placements, and orthopedic assessments.

Other imaging modalities mentioned, such as magnetic fields, radiofrequency waves, and ultrasound waves, refer to different technologies used in MRI, certain types of therapeutic approaches, and ultrasound imaging, respectively. They do not provide the real-time imaging capability that is characteristic of fluoroscopy.
