ABSTRACT
A method for developing a three-dimensional visual system for simulating augmentation mammaplasty based on OpenGL is proposed. The 3D reconstruction of breast surface using NURBS, reality simulation of the breast surface, parametric design of mammary prosthesis, and simulation of postoperative effect are described. The system may provide a means for better communication between the surgeons and patients.

<p><b>OBJECTIVE</b>To measure breast basic dimension by using computer-aided projection fringe system.</p><p><b>METHODS</b>A system has been developed for measuring breast basic dimension based on computer-aided projection fringe measurement and programming software. Plastic manikins breast's SN-N (sternal notch to nipple distance), N-ML (nipple to midline distance), N-N (internipple distance), MBW (base width of breast) and N-IMF (nipple to inframammary fold distance) are measured with this system. At the same time, these items are also measured with routine ruler.</p><p><b>RESULTS</b>This study indicate that the system has some merits: (1) non-touching measurement; (2) it is very rapid, the patient measured need hold his breath only 0.5 second, and all the time it takes is about 2.5 minutes; (3) the measurement's sensitivity is as high as to 0.6 mm, which meets the clinic requirement entirely; (4) the measurement's accuracy of the system is not significantly when comparing to the routine ruler's.</p><p><b>CONCLUSIONS</b>Computer-aided projection fringe system for measuring breast basic dimension is feasible and advanced.</p>
