Image-guided surgery planning for breast reconstruction flap design

In this paper, a computer aided breast reconstruction surgery planning method is proposed, computing the breast shape after excision of one for some diseases such as cancer. In order to achieve a reasonable result, we calculate shape, area, volume and depth of the skin and muscle for the reconstruction, based on another wholesome breast. The solution is described as follows: firstly, the breast´s MRI data of patient is input; then, the region of interest is obtained from healthy breast employing balloon segmentation algorithm and retrieve surface mesh data; thirdly, the dimensional surface skin mesh is mapped onto the plane, in order to attain the shape and volume of the flap for breast reconstruction, by the help of deformable model; finally the approximate curve volume shape of flap is calculated. Other contributing methods such as mesh smoothing and cutting of triangulated surface are also discussed. The doctors validation and evaluation process are also provided to ensure the robust and stable result of virtual surgery planning.
