目的对当前医学成像系统显示器性能进行测定,评价其所显示的图像是否能够正确反映患者影像检查的真实情况,为医生能够调阅稳定的和一致性的医学图像提供依据。方法根据AAPM TG18提出的关于医学成像系统显示性能测试的指导标准,在2015年1月至7月,对笔者所在医院医学影像科中用于医学图像调阅的医用显示器进行3次性能测试。结果被检测的医用显示器的图像稳定性和一致性较好,其各项性能指标均符合AAPM TG18标准。结论医用显示器在数字医疗系统中是医学影像的最终呈现者,其图像显示的稳定性和一致性在医生进行软阅读中有重要作用,AAPM TG18标准能够对医用显示器性能的各个性能进行系统的评价,适合推广使用。
Objective To evaluate the performance of current medical imaging system display and evaluate whether the displayed image can correctly reflect the actual situation of the patient’s image examination and provide the basis for doctors to read stable and consistent medical images. Methods According to the guidelines of AAPM TG18 on the display performance of medical imaging system, three performance tests were performed on the medical monitors for medical image retrieval in the medical imaging department of the author’s hospital from January to July 2015. Results The medical monitors tested showed good image stability and consistency, and all the performance indexes of the medical monitors met the AAPM TG18 standard. Conclusion Medical monitors are the ultimate presenters of medical imaging in digital medical systems. The stability and consistency of medical images play an important role in doctors’ soft reading. The AAPM TG18 standard can systematically evaluate the performance of medical monitors , Suitable for promotion use.
