Suppose we have a first-generation CT scanner with a mechanical problem. For each projection angle, it measures zero at . Now we use the scanner to image a uniform disk.

(a) Sketch the sinogram.

(b) What would the reconstructed image look like?

(c) If instead the scanner always zeroes the measurement at , what

would the reconstructed image look like?
