What is the main purpose of an image intensifier in fluoroscopy?

The primary function of an image intensifier in fluoroscopy is to enhance the brightness of the fluoroscopic images, making it easier for medical professionals to view the details of the structures and functions being examined. When x-rays pass through the body, they produce a relatively weak image that may not be easily interpretable. The image intensifier amplifies this signal, allowing the resultant image to be much brighter. This increased brightness is crucial in allowing practitioners to visualize dynamic processes in real-time during the examination.

While an image intensifier does contribute to viewing images on a monitor, its core role is to increase image brightness, which enhances visibility and diagnostic confidence. The ability to modify the x-ray beam or produce dynamic imaging involves different components and processes within the fluoroscopic system. The enhancement of brightness is what makes the image intensifier a fundamental element in fluoroscopic procedures, optimizing the quality of the diagnostic imaging.
