In other words, by stacking 2D images, you get the volume (case or patient). They're all taken at the same time/week, which is week 0 in our case.\nThe weeks and FVC values in the CSV sheets represent the progression with time, for example: week 10 indicates that this measurement has been taken 10 weeks after the CT scan. \nHope this helps.</p>",
