Illustration of stereovision surface reconstruction: rectified left (a) and right (b) camera images after dural opening, allow the correspondence point search to occur along a horizontal line (i.e., epipolar line). The reconstructed 3D cortical surface is shown in pMR image space (c). Reconstructed cortical surface cross-sections on a pMR axial image are shown (d) at four distinct surgical stages (0: before dural opening; 1: after dural opening; 2: before tumor resection; and 3: after partial tumor resection).
