The expected scanning grayscale values from part a in the Y and X directions are:

Y: 1 0 1 0 0 0 1 1 0 0 0 0 1 0 0 0 1 1 0 0 0 0 0 0

X: 1 0 1 0 1 0 0 0 0 0 1 0 0 1 0 0 1 0 0 0 0 1 0 0

b) ( 0.75 point) Using the values you calculated in part a), please create a (CT) image for the 16 pixels using uniform backprojection. Just put the pixel intensity values (you don't have to actually shade the image). (Note: If you can't figure out part a), put 0101 for your values for the x and y grayscale values and solve that problem) c) (0.25 point) How many projections would I have to do in order to recreate the original CT
