Hello,
I have many DICOM serial images (210 slices each one) for the same core but in two different conditions. I need to subtract two files (Slice by slice) in the same location and compare them. Let's assume the image parameters like pixel spacing, slice thickness, etc. are the same. But the core may moved after each scan. How can I achieve the image alignment? in the end, I would like to find a 2D matrix (i, j) with the pixel by pixel substraction values between the two series of images.
Thank you!
