Abstract Breast cancer is the second leading cause of cancer death in American women. Breast reconstruction surgery is an important component of the breast cancer treatment process, that is used to rebuild a breast form that has been removed due to cancer surgery. It is integral to improving the cancer patient's health-related quality of life. However, planning and evaluation of the surgery are done subjectively, and the result is not always aesthetically satisfactory. Standards for breast reconstruction have evolved over the past two decades, and patients and surgeons alike expect natural, symmetrical -looking surgical outcomes. Surgeons rely on their personal experience and on subjective visual assessment skills to achieve these results. Similarly, aesthetic outcome assessment methods, following surgery, are rather subjective, and are based on observer evaluation of physical changes in breast morphology and symmetry. With recent developments in three-dimensional (3D) imaging, there is now an opportunity to develop software that permit use of breast morphometry and computerized simulations for treatment planning, clinical consultation, and objective assessment of postoperative results. Currently, there is no stand-alone, imaging-device independent software for a surgeon to automate measurements for objectively formulating a surgical plan or generate realistic simulations of breast shape. To address this challenge, we propose the development of software for quantitative assessment of breast shape. 3D imaging has been validated for the clinical assessment of breast aesthetics but has seen limited use for simulation and surgical planning due to the exorbitant costs (~$100-300K) of imaging equipment and lack of appropriate image analysis tools. Low-cost (~8K), portable hand-held 3D scanners are now available, but software for enabling breast morphometric analysis for surgical planning is lacking. In this Phase I STTR study, Soft Imaging, LLC is collaborating with the University of Houston (UH) and The University of Texas MD Anderson Cancer Center to develop 3D image analysis software that will utilize innovative and novel 3D image analysis algorithms for enabling (1) automated approaches for breast morphometry and surgical planning and (2) employ a parametric modeling approach based on 3D spherical harmonics (SPHARM) to model breast shape, to provide realistic simulations for visualization during clinical consultations. This will help breast cancer patients make informed decisions about their breast reconstruction treatment choices, calibrate her expectations, and be more comfortable with her treatment choices. At the completion of this Phase I feasibility study, a future Phase II project, will develop a prototype for clinical testing at multiple sites, followed by Phase III commercialization. Applications would improve breast cancer care in several ways, such as; surgical planning, enabling personalized simulations of surgical outcomes, surgical education, and planning of comfortable postoperative garments (bras) for use during surgical recovery.

抽象的 乳腺癌是美国女性癌症死亡的第二大原因。乳房再造 手术是乳腺癌治疗过程的重要组成部分，用于重建乳房形状 由于癌症手术已被移除。它对于提高癌症患者的健康相关质量至关重要 的生活。然而，手术的计划和评估都是主观的，结果并不总是 审美上令人满意。 乳房重建的标准在过去二十年中不断发展，患者和外科医生 同样期待自然、对称的手术结果。外科医生依靠他们的个人经验和 依靠主观视觉评估技能来实现这些结果。同样，审美结果评估 手术后的方法相当主观，并且基于观察者对身体变化的评估 乳房的形态和对称性。随着三维（3D）成像的最新发展，现在 有机会开发允许使用乳房形态测量和计算机模拟的软件 治疗计划、临床咨询和术后结果的客观评估。目前，有 没有独立于成像设备的独立软件可供外科医生自动进行客观测量 制定手术计划或生成真实的乳房形状模拟。 为了应对这一挑战，我们建议开发用于乳房定量评估的软件 形状。 3D 成像已被验证可用于乳房美观的临床评估，但用途有限 由于成像设备的成本过高（约 100-30 万美元）且缺乏 适当的图像分析工具。低成本 (~8K) 便携式手持式 3D 扫描仪现已上市，但 缺乏用于手术规划的乳房形态测量分析软件。在这项第一期 STTR 研究中， Soft Imaging, LLC 与休斯顿大学 (UH) 和德克萨斯大学 MD 安德森分校合作 癌症中心将开发 3D 图像分析软件，该软件将利用创新和新颖的 3D 图像分析 用于实现（1）乳房形态测量和手术计划自动化方法以及（2）采用的算法 基于 3D 球谐函数 (SPHARM) 的参数化建模方法对乳房形状进行建模，以提供 临床咨询期间可视化的真实模拟。这将帮助乳腺癌患者 关于乳房重建治疗选择的明智决定，调整她的期望，并更加 对她的治疗选择感到满意。 在第一阶段可行性研究完成后，未来的第二阶段项目将开发一个原型 在多个地点进行临床测试，然后进行 III 期商业化。应用可以改善乳房 癌症护理有多种方式，例如；手术计划，实现手术结果的个性化模拟， 手术教育，以及规划手术恢复期间使用的舒适术后服装（胸罩）。
