Operating system: macOS Catalina 10.15.1
Slicer version: 4.11
Expected behavior: Images upload clear
Actual behavior: Images upload blurry and two errors showed up (when looking at the slices individually they are clear, but when uploading all together it looks like this.
I tried enabling acquisition geometry regularization, but it didn’t change anything.
Most probably you have 3 series, each is high-resolution only along one image axis. See this topic for more details:
I went onto the View Controllers Module and found that there are many series options and when I switch to a different series the image appears clear. I am not sure what I am doing though or what these series are. Could you try to explain what is happening?
In an imaging study, usually many series are acquired and even more can be created by reconstructing the same acquired data in many different ways. Use those sequences that work the best for you.
Thanks Andras. I have a follow up question. Would I be able to make 3D measurements using three different series of images (one for each orientation)? Or do I need to somehow align the series first? If so, what is the best way to do this?
First you need to verify that there is no significant displacement between these images. If they are well aligned (which is probably the case) then you can make measurements on any combination of them. You just need to be aware that accuracy of your measurements may be limited to the slice spacing (which may be a magnitude larger then pixel spacing within the slice).
