Abstract:
1. A system for determining a breast volume in an automatic fashion from a three-dimensional (3-D) representation of a contoured surface of an upper torso, comprising: (a) a 3-D imaging device for obtaining said 3-D representation of said contoured surface of said upper torso; (b) a computer analysis device coupled to said 3-D imaging device comprising one or more computer-implemented modules for determining rate of change of contours of said 3-D representation of said upper torso; (c) said computer analysis device further comprising one or more computer-implemented modules for determining from said 3-D representation an unclosed yet continuous 3-D breast fold curve by analyzing said rate of change of said contours of said 3-D representation, wherein said determined 3-D breast fold curve is along a 3-D surface of said 3-D representation defining a lower part of the breast; (d) said computer analysis device further comprising one or more computer-implemented modules for determining from said 3-D representation 3-D chest parameters by analyzing said contours and said rate of change of said contours of said 3-D representation, wherein said 3-D chest parameters comprise at least one anterior axillary line corresponding to said determined 3-D breast fold curve and an anterior chest midline; (e) said computer analysis device further comprising one or more computer-implemented modules for determining a partial chest wall from said determined 3-D breast fold curve and said determined 3-D chest parameters, whereby said determined partial chest wall is optimized to features of a 3-D model of a chest wall and wherein said optimized partial chest wall corresponds to said determined 3-D breast fold curve; (f) said computer analysis device further comprising one or more computer-implemented modules for determining an original breast volume from said determined 3-D breast fold curve, said optimized partial chest wall and a 3-D surface integral of said 3-D representation of said upper torso; and (g) a displaying or reporting device coupled to said computer analysis device for displaying or reporting said original breast volume.
