 Hi, How does x, y, z correspond to our image(512,512), say we use 1 image only. In this case will z=1? Also, what exactly is dx, dy, and dz? should that be set to 1,1,0 if I'm interested in 1 pixel of my image at a time? basically i want dose deposition at each pixel in my (512,512) image, how would I do this using x,y,z,dx,dy,dz? (1,1,0)(1,1,0)0 (1,2,0)(1,1,0)0 . .
