摘要
Abstract
Objective: The detective quantum efficiency is the most suitable parameter to describe the X-ray imaging device. DQE determination method is currently in the initial stage, and becomes the study focus Methods: DQE for the medical digital X-ray flat panel detector system has been measured in accordance with the international standard IEC62220-1. Results: Discussing the practice of detecting DQE and calculation methods for the modulation transfer function and noise power and make the curve. Conclusion:This article analyses the determination and calculation principle of the DQE in detail, and make it from the theory to the practice.关键词
