A robust method and affordable system for the 3D-surface reconstruction of patient torso to evaluate cosmetic outcome after Breast Conservative Therapy

摘要

Breast cancer is the most common cancer among women around the world. Breast Conservative Therapy (BCT) is a treatment where the complete tumor and a margin of healthy tissue are surgically removed (partial mastectomy or lumpectomy) and the remaining breast tissue receives radiotherapy. Although the outcome of this treatment method usually provides good clinical results, some cosmetic defects like asymmetry may nevertheless emerge. The objective of this work is to present a robust, mobile, and affordable three-dimensional (3D) surface reconstruction system that can be used to assess post-surgery breast cosmetic outcome after a lumpectomy. Preliminary results obtained with this system have allowed us to test some of the hypotheses we made in our multiscale predictive modeling of BCT outcome.
