AN ACCURATE AND ERGONOMIC METHOD OF REGISTRATION FOR IMAGE-GUIDED NEUROSURGERY COMPUTERIZED MEDICAL IMAGING AND GRAPHICS Henderson, J. M., Smith, K. R., Bucholz, R. D. 1994; 18 (4): 273-277

Abstract

We have developed a system for accurately and conveniently achieving surgical registration for image-guided neurosurgery, based on alignment and matching of patient forehead contours. The system consists of a contour digitizer that is used in the operating room to acquire patient contours, editing software for extracting contours from patient image data sets, and a contour-match algorithm for aligning the two contours and performing data set registration. Initial tests of the individual portions of the system have found each to be robust; we are in the process of refining the design of the optical digitizer in order to further automate the procedure as well as provide increased accuracy.
