I am working with CT data that have been acquired from the same patients at different time points. My aim is to evaluate the tumor shrinkage (I have established it well in the 3D slicer, and works well) and tumor’s movement (this part is the question).
Since I am working on the lung (which has breathing phases, and I use average CT), the determination of the tumor’s movement is challanging. I plan to use a coordinate system in which I will assign the XYZ axis by taking advantage of the human anatomy to determine coordinates for each time point.
Is there any tool (plugins) so that I can do it?
Please let me know your ideas.
Thanks for your help.
