Study on test methods of detective quantum efficiency in DR system
摘要
Abstract
Objective: This paper introduces the test methods and significance of detective quantum efficiency (DQE). Methods:According to the IEC 62220-1 standard, test methods of DQE is analyzed, relationships between DQE and other important factors which might affect the digital X-ray image quality are analyzed. Results: Main factors including noise, contrast, MTF, patient’s dose are concluded. Conclusion:DQE combines some important factors together including image contrast, noise, and spatial resolution and input X-ray dose, which makes it as the most accurate method in evaluating digital X-ray image quality.关键词
