Describe the Bug

Hello, when I use OHIF to open a set of MIP images of MRI, when I switch the images, there will be a problem of image distortion (vertical rotation), when I investigated, I found that there is a relationship with the tag information of ImageOrientationPatient, when I delete this tag of the image, the distortion problem disappeared, and when I open the images with MicroDICOM and other reading tools, they are all normal. I used MicroDICOM and other viewing tools to open the image.

Hi,Here is another 3D sequence data to share, when switching images also appeared to rotate abnormally (I troubleshooting to locate that it is an abnormal scale problem, but I do not know how to cause it), when I remove ImageOrientationPatient, the display is normal!
