There is a 4-pixel by 4-pixel image shown below. If we apply Gx=5Gauss/cm as the frequency encoding gradient and Gy-10Gauss/cm as the phase encoding gradient, what is the final signal in terms of summation of cosines? Gy = 10G/cm Y(cm) 0(0,3) 1(1,3) 5(2,3) -2(3,3) 1(0,2) 2(1,2) 0(2,2) 3(3,2) 4(0,1) 2(1,1) -1(2,1) 0(3,1) -3(0,0) 0 (1,0) 2(2,0) 1(3,0) Gx = 5G/cm X(cm)
