“…The LP is the point where the inframammary fold ends laterally. The Inferior Breast-Chest contour (IBC), which is the lowest visible boundary of the breast, was detected using a contour detection algorithm [12]. The breast was cropped using the annotated fiducial points and the detected IBC.…”

While advancements in plastic surgery techniques and technology have facilitated improved aesthetic outcomes in both cosmetic and reconstructive breast surgery, communicating potential outcomes to the patient prior to the surgery, and understanding their aesthetic preferences for breast shape and size still remains a challenge. Unrealistic expectations related breast aesthetics can lead to patients' dissatisfaction with surgical outcomes. Currently, plastic surgeons rely on drawings or images of former patients to explain surgical procedures and their possible outcomes. The ability to visualize the expected post-surgery breast would, to a large extent, mitigate this challenge and aid both surgical planning, and inform decision making. In this work we propose a software tool that will enable visualization of three-dimensional (3D) images of patient's breasts and allow real time simulation of morphological changes on the breast. 3D surface images of the patients' torso were obtained using stereophotogrammetry during their clinical visits. The front torso area between the sternal notch and the umbilicus was captured. The breast region of interest was extracted semi-automatically from the 3D surface mesh of the torso and a computational model using Fourier based spherical harmonics (SPHARM) was created. SPHARM coefficients obtained from modeling were previously observed to have direct correlation with breast size and shape measurements, such as height, width, projection and ptosis. Simulation of breast shape changes was achieved by modifying these coefficients. We designed an application for visualization of the simulated breast on the 3D surface image of the torso with real time simulation of breast size changes by modifying the model parameters. The work in this study addresses design and development of the visualization software. Future work will focus on evaluating the visualization framework to assess surgeon and patient acceptance on usability, and feasibility for clinical translation.

“…The seven measurements were made with custom software that allows for viewing, manipulating, and measuring 3D images [5]- [9]. Two trained researchers (KN and EJ) manually selected the eight required fiducial points (Most Projecting Point of the breast (MPP), Inframammary Fold at the meridian (IMF), Sternal Notch (SN), Medial Point -most medial point at the end of the IMF (MP), Lateral Pointmost lateral point at the end of the IMF (LP), Midline (M), Mid-clavicle (MC), Transition Point -post of transition from the chest wall to the breast on the meridian line (TP)) when present on each image, which were verified by an experienced reconstructive surgeon (GR).…”

Breast reconstruction patients face unique challenges in finding a properly fitting bra after breast surgery, leading to decreased bra comfort and psychosocial functioning. In addition to considerations such as location of seams and choice of fabric, identifying trends in how breast shape and symmetry measurements change between native breasts and reconstructed breasts may help inform bra design for reconstruction patients. We have previously developed a correspondence system between bra measurements and clinical breast measurements used by reconstructive surgeons. The selected measurements describe the size and projection of the breasts as well as their relative location on the torso as captured by clinical photographs. In this study, we explore how reconstruction changes breast measurements pertinent to bra design by analyzing 3D surface torso images of 15 unilateral implantbased breast reconstruction patients before and after their reconstruction surgery. Using custom software developed at University of Houston, two researchers measured several breast properties on a 3D surface torso image taken before mastectomy and on another image taken after each patient's final implants had been placed. 14 of the 15 patients had completed their reconstruction surgeries by the time that the second image was taken. We compared the differences in measurements between the pre-mastectomy image and post-mastectomy and reconstruction image for both breasts separately, as well as change in right-left symmetry of the measurements between the pre-and post-images. 14 out of the 15 patients had a revision surgery performed on the contralateral breast to enhance postreconstruction symmetry. The three most affected measurements between native breasts and breasts reconstructed after mastectomy were the sternal notch to most projecting point, lateral point to most projecting point, and mid-clavicle to transition point to most projecting point. These changes can be attributed to the size and shape of the implants used to compensate for the removal of native breast tissue, which change the fundamental footprint and curvature of the breast. Asymmetry between the breasts also increased after breast cancer treatment despite reconstruction and contralateral revision procedures. These measurements can be used to inform bra designers of what adjustments may be needed to bra patterns to improve fit for reconstruction patients.
