What is the primary function of the image intensifier in fluoroscopy?

The primary function of the image intensifier in fluoroscopy is to enhance the brightness of the fluoroscopic image. This device plays a vital role in converting the X-ray photons that pass through the patient’s body into a visible light image that can be viewed on a monitor.

By amplifying the light, the image intensifier allows for a clearer and more detailed representation of the internal structures being examined, especially in darker environments. This enhancement is crucial for enabling healthcare professionals to visualize the real-time movement and function of organs, which aids in diagnosis and treatment planning.

While the image intensifier does contribute to reducing radiation exposure by allowing clearer images at lower radiation doses, its main job is centered on brightness enhancement. Similarly, capturing X-ray images and maintaining a consistent frame rate are important functions related to the overall fluoroscopic system, but they are not the primary roles of the image intensifier itself.
