Objective To study the causes and control countermeasures of the noise of computed radiography(CR). Methods One thousand cases CR image was retrospectively analysed. Results The more dose the exposure, The less will be the amount of noise.The more long the use time of imaging plate, the more will be the amount of noise. Conclusion The noise are key point to influence imaging quality of computed radiography. Optimal application noise control countermeasures can provide accurate informations for clinical diagnosis.
