The overall aim of this study was to assess the accuracy, reproducibility and stability of a high resolution passive stereophotogrammetry system to image a female mannequin torso, to validate measurements made on the textured virtual surface compared with those obtained using manual techniques and to develop an approach to make objective measurements of the female breast. 3D surface imaging was carried out on a textured female torso and measurements made in accordance with the system of mammometrics. Linear errors in measurements were less than 0.5mm, system calibration produced errors of less than 1.0mm over 94% over the surface and intra-rater reliability measured by ICC=0.999. The mean difference between manual and digital curved surface distances was 1.36mm with maximum and minimum differences of 3.15mm and 0.02mm, respectively. The stereophotogrammetry system has been demonstrated to perform accurately and reliably with specific reference to breast assessment.
