The digital x-ray detector is a sophisticated and expensive device that plays a decisive role in improving image quality and reducing X-ray radiation dose.
Digital x-ray detector are an important part of DR radiography.In X-ray radiography, compared with ordinary X-ray images, digital X-ray images have high resolution, wide gray scale and large amount of information, which is helpful to improve diagnostic accuracy.
In digital x-ray detector, X-ray signals are converted into electrical signals by flat detector, so the characteristics of digital x-ray detector will have a great impact on the quality of DR image.
Spatial resolution affects the resolution ability of the image to detail, while DQE affects the contrast of the image.In the equipment that requires high image density and resolution, indirect conversion flat panel detector, such as chest projection, should be used.
In the equipment with high image spatial resolution requirement, direct conversion detector should be used
