I am not able to import a time-resolved cardiac CT sequence, consisting of 10 time points and 300 slices. I tried exporting DICOMs both as separate folders for each time point, and also all the DICOMs in one single folder. I used the examine button and selected different Multivolume options available individually and together (see below). I also tried different combination of “DICOM Plugins” to no avail.
When I scroll through the images in metadata, it goes through all the slices in a time point before advancing to the next time point. Is there a way to sort/read the files in Slicer based on “slice position”?
Your screenshots look OK to me. What happens if you click the “Load” button? In both screenshots, the top, checked option looks like it is a 10 frame volume sequence, which is what you want. You can then go through each frame using the sequence browser.
Both the first and second options load as Volume Sequences that I can play back. The first is the right one to choose, the second one loads but has step/banding artifacts because it organizes by time instead of by cardiac cycle.
What version of Slicer are you using? I loaded with 5.2.1, which is a little behind the current stable version. If you are using an older version, try upgrading to the current stable and see if that works. The DICOM plugin you need enabled is MultiVolumeImporterPlugin, and then make sure that the one you select is described as a Volume Sequence by CardiacCycle (not a MultiVolume by CardiacCycle; somewhat confusingly, MultiVolume is a deprecated predecessor to Volume Sequences. It is OK that the “Reader” column says MultiVolume, you just don’t want that in the first column). It is possible that the version you are using is getting tripped up by the StudyID, StudyDescription, and SeriesDescription DICOM tags being empty. If you are unable to update your Slicer version, I would try filling in those tags with something and see if that allows you to load.
@mikebind It appears @SassanHashemi is using the latest version of Slicer (5.6.1). If it is working for you with Slicer 5.2.1, maybe you can confirm that it is also working with Slicer 5.6.1.
Apologies I didn’t have access to my laptop for a few days.
This is very strange! I had anonymized the data I shared with you under a different name. I loaded the version I shared with you and to my surprise it loaded fine, exactly the way it loaded for you!
Maybe try to copy the files again, maybe to a folder that has shorter name.
You can also enable detailed DICOM logging (in menu: Edit / Application settings / DICOM) and check the application log after clicking “Examine” and see if there is any message related to CardiacCycle.
