A medical imaging system has the following line spread function, where

α = 2 radians/cm:

(a) Suppose a bar phantom is imaged, where the bars have width w, separation w, and unity height. Assume what are the responses of the system at the center of a bar and halfway between two bars?

(b) From the line spread function, can we tell whether the system is isotropic?

(c) Assume the system is separable with Compute

Its transfer function.
