Open 2 files at the same time

如图所示，我想同时在右边展示左边的两个文件，并且能够分别做标记，互相不影响，请问我该怎么做？

Good idea!

• For your work, why do you want this? To show 2 MRI scans of a single patient taken at different times?
• Can you share some screenshots of how other viewers let users pick which images to show side by side?

我想要制作对比功能，对比一个患者不同时间的MRI图像，目前我不知道该如何实现这个功能。我看了好多其他用户提交的issue，没有找到类似的问题或解决方案。

For example Weasis allows you to do this.

In the thumbnails ribbon you have patient, study and series nested by study, if the studies belong to the same patient (by patient id) you can divide the viewport in two and drag the desired series to each of the sides regardless of whether they are from different studies

volview好像没有拖动功能。我现在能打开两个视图，但是这两个视图指向同一个对象，在左边做标记的同时右边也会出现同样的标记
