The resolution of the image intensifier is reduced

The image intensifier is an X-ray image intensifier that converts invisible X-ray images into visible images and enhances the brightness of the images.
The resolution of the image intensifier is limited by the resolution of the input and output phosphor screens and the ability of the focusing electrode to maintain the image when the image is transferred from the input screen to the output screen. For the CsI input image intensifier screen, the average resolution is 4 line pairs/mm.
The reasons for the reduction of the external resolution of the image intensifier include: the scattered radiation in the x beam received by the input screen; the movement of the patient and the limited size of the focal spot cause the image to be out of focus.
The resolution, brightness, and contrast of the image produced by the X-ray image intensifier reach the maximum in the center of the image and gradually decrease toward the periphery. The brightness reduction along the edges of the image is usually no more than 25%.
