With the advent of three-dimensional (3D) surface imaging technology, objective measurements of breast aesthetics, such as contour, surface area, shape, size, and volume are now possible, and studies have demonstrated its utility and efficacy in clinical medicine. Moreover, several relatively low-cost portable hand-held 3D scanners are now commercially available, which has increased the likelihood of the technology finding widespread clinical adoption. An understanding of the capabilities and limitations of 3D imaging technology and corresponding measurements is essential for its successful application in pre-operative planning as well as post-operative assessments. Breast volume is a key outcome measure in aesthetic and reconstructive surgery; thus, it is critical to not only have validated algorithms for accurate measurements, but to also understand the ability of the technology to resolve and detect volume changes. Inconsistencies in volume measurement and lack of appropriate standardization protocols can influence applications that utilize quantitative measurements. For example, changes in breast volume need to be quantified to maintain breast symmetry and any inconsistencies may impact the surgeon's ability to formalize pre-operative plans. In this study, we assessed the resolution of 3D imaging in terms of assessing breast volume change and compared volume measurements made using a non-portable 3D imaging system (3dMDTorso) and a hand-held 3D scanner (Go!SCAN 3D). Using adjustable implants with varying volumes, with the non-portable system and customized volume computation software, we could reliably detect changes in volume as low as 5.5+-2.6cc. In addition, volume measurements made using the non-portable system and the hand-held scanner were highly correlated (R2=0.99), demonstrating feasibility of using the portable hand-held scanner for breast volume measurements.
