I am currently working on lung CT to evaluate the changes in lung tissue and tumor size. I have CT scans at 8 different time points such as Planning CT, Therapy Control CT, and Follow-up CTs.
I want to use planning CT as the base data (the first data point) and visualize the changes over time. I have seen many tools (such as ANTs for image registration) and some plugins in 3D Slicer, however; I am not sure which one I need to use.
The thing in my mind is simply that;
Image registration by labeling anatomic points in two CTs and then extracting the changes in lung tissue (this can be done in a manual/autonomous or semi/autonomous fashion). Then. visualize the changes as a heat map (such as Jacobian Map )and extract the statistics
I have seen ChangeTracker, SlicerMorph, and SlicerElastix in the extension manager. However, I am unsure which one may fit my problem better, and which pipeline.
