You’re seeing the CT slices which is how a CT is done - many slices. The images I posted are CT slices put in 3D. My CT scan images included 4 3D images so I could better see what the CT scan showed. Some of our members have been able to get the radiology lab where their CT was done, do a 3D conversion of their images. Others have had to do it themselves when they couldn’t get it done professionally.
There are free 3D slicer apps online to convert slices to 3D images. One that’s popular among our forum members is RadiAnt Viewer - https://www.radiantviewer.com.
A few years ago, our member, @SnappleofDiscord, posted detailed instructions for using 3D slicer software w/ a link to the specific software he used.
I hope one or the other of these is helpful for you.
