Abstract: The resolution of computed radiography (CR) technology is an important parameter to describe the digital image quality, which is characterized by its particularity compared with the traditional film technology. In order to introduce the CR technology to the nondestructive testing of nuclear power plants, the factors affecting the resolution are analyzed and tested. The test results show that the contrast resolution and the spatial resolution are quite critical to the CR image quality. The outcome from the study can provide solid references to determine technical parameters of CR technology.

Key words: computed radiography (CR), resolution, image quality, contrast resolution, spatial resolution
