Fig. 10.

Same image as shown in Fig. 7 with an attempt to display the full magnitude of the image vectors with the correct sign. (a) A simple algorithm which uses the sign of the real part of the image vector after phase correction to determine the sign of the displayed pixel. Note the increased low-signal noise, jagged boundaries, and anaomalous pixels. (b) The phase sensitive image after the image processing described in the text. (c) The residual signal remaining in the imaginary image after this processing. The window for (a) and (b) is the same as in Fig. 7(b); the window for (c) is the same as in Fig. 7(c).
