Algorithm flowchart of the program used to convert the projected images into slices. The sinograms were computed by FBP based on the energy, distance and number of projected images. Because of the nonuniform thickness of the tissues of the eye, the gray value of the background has not been agreed. So we adjusted the gray value of background to remove the background noise.
