Suppose we wish to image an object in all three dimensions, that is, we want our final image to be an N × N × N array of voxels with isotropic dimensions. However, our ability to produce RF pulses is limited to short bursts of unmodulated RF; therefore, we cannot use slice selection.

(a) Can you think of a method to the object? (Hint: look at the phase encoding section of the book and extend these ideas.)

(b) What would the equation for the signal be?

(c) How would you reconstruct the image?
