To solve the problems of image displays in filmless radiology conferences for the purpose of teaching, we made an experimental design of a conference system with dual 50-in. plasma monitors for displaying larger images and a shared folder containing shortcuts to images for quick display during conferences on the desktop of each client computer in a picture archival and communication system. The image quality of the monitors was evaluated using the TG18-QC test pattern. The display time of images was measured in 20 cases when the shared folder was used and when it was not. Monitor screen size and image quality, operability, display time of images, and overall impression given by the system were evaluated subjectively by five radiologists. Although the image quality of the monitor was not as high as that of the high-resolution monitors used for diagnostic radiology, its performance was good enough for teaching. The average display time using the shared folder (2.6 +/- 0.39 s) was significantly shorter than without it (16.9 +/- 5.04 s; p = 2.85 x 10(-6)). Despite the need for certain improvements in monitor size and in the operability of the system, the radiologists considered the system suitable for radiology teaching conferences. We believe that this system is useful for institutions that intend to introduce a filmless system for filmless radiology teaching conferences.
为了解决无胶片放射学会议中图像显示的问题，以便于教学，我们设计了一个实验性的会议系统，该系统使用两个 50 英寸的等离子监视器来显示更大的图像，并在每个客户端计算机的桌面上共享一个文件夹，其中包含图像的快捷方式，以便在会议期间快速显示。使用 TG18-QC 测试图案评估监视器的图像质量。在使用和不使用共享文件夹的情况下，测量了 20 个案例中图像的显示时间。五位放射科医生对监视器屏幕尺寸和图像质量、可操作性、图像显示时间以及系统的整体印象进行了主观评估。尽管监视器的图像质量不如用于诊断放射学的高分辨率监视器高，但它的性能足以用于教学。使用共享文件夹的平均显示时间（2.6 +/- 0.39 s）明显短于不使用时的时间（16.9 +/- 5.04 s；p = 2.85 x 10(-6)）。尽管需要改进监视器尺寸和系统的操作性，但放射科医生认为该系统适合放射学教学会议。我们相信，对于那些打算引入无胶片系统进行无胶片放射学教学会议的机构来说，这个系统是有用的。
