In image intensification, what is the role of the output screen?

The output screen plays a crucial role in image intensification by converting incoming x-rays into visible light. This is essential in fluoroscopy, as it allows for the visualization of structures within the body on a display monitor. When x-rays strike the output screen, which is typically made of a phosphorescent material, they excite the atoms within the screen, causing them to emit visible light. This process enhances the image quality and allows for real-time viewing of dynamic processes within the body, significantly improving the diagnostic capabilities of fluoroscopy.

The conversion of x-rays to visible light is important because it increases the brightness of the image, making it easier for healthcare providers to interpret the images during procedures. This function is a fundamental aspect of the image intensification process, ensuring that the images produced are both high-quality and efficiently visible.
