The rotating display is a useful method for reviewing single photon emission computed tomography (SPECT) data. This study evaluated the requirements for a subjectively pleasing and useful implementation of this technique. Twelve SPECT data sets were modified and viewed by several observers who recorded the minimum framing rates for apparent smooth rotation, 3D effect, effects of image size, and other parameters. The results showed that a minimum of 16 frames was needed for a useful display. Smaller image sizes and more frames were preferred. The recommended minimal framing rate for a 64-frame study is 16-17 frames per second and for a 32-frame study, 12-13 frames per second. Other enhancements also were useful.
旋转显示是一种用于回顾单光子发射计算机断层扫描（SPECT）数据的有用方法。本研究评估了该技术在主观上令人满意且有用的实现所需的条件。对12个SPECT数据集进行了修改，并由几位观察者进行查看，他们记录了实现明显平滑旋转、三维效果、图像大小影响及其他参数所需的最低帧率。结果表明，要实现有用的显示至少需要16帧。较小的图像尺寸和更多的帧数更受青睐。对于64帧研究，推荐的最低帧率为每秒16 - 17帧；对于32帧研究，推荐的最低帧率为每秒12 - 13帧。其他增强功能也很有用。
