What is indicated by the term 'image intensifier' in fluoroscopy?

The term 'image intensifier' in fluoroscopy refers to a device that enhances the quality of images produced during the examination. It plays a crucial role in converting the radiation from the X-ray source that passes through the patient into a visible image that can be viewed on a monitor. The device uses a combination of an input fluorescent screen, which converts X-rays to visible light, and various electronic components to amplify the light signal, effectively making the image brighter and more detailed. This enhancement allows for better visualization of structures and processes within the body, facilitating accurate diagnosis and treatment during fluoroscopic procedures. The functionality of an image intensifier is essential in improving the overall reliability and usefulness of fluoroscopy in clinical settings.
