The researchers used high-speed imaging of folks coughing and sneezing, along with simulations and mathematical models.

研究人员使用高速动扫描成像记下人们咳嗽和打喷嚏的全过程，后进行数据模拟和模型分析。

So yeah, so the University of Utah conducted these tests where they took dynamic MRI, so like you don't have to just be laying down still to get an MRI image of a person.

是的，犹他大学进行了这些测试，他们使用动振成像，也就是说，你不必一直躺着不动就能获得人体的振图像。
