Project Summary Approximately 12% of women in the United States will develop breast cancer in their lifetime, including an estimated 276,480 new cases of invasive breast cancer, 48,350 new cases of non-invasive (in-situ) breast cancer, and 42,170 deaths in 2020. Breast cancer is the second most diagnosed cancer in women, with a death rate second only to lung cancer. Although mammography is the gold standard for initial breast cancer screening, 10-30% of breast cancers can be missed at mammography. Despite several underlying explanations, including dense breast tissue, slow growing lesions, perception error, and incorrect interpretation of suspect findings, errors in positioning the breast are common and have a profound effect on mammography's accuracy as a diagnostic modality. Further, positioning errors are the primary reason breast centers fail reaccreditation. These problems stem from the fact that experience in breast positioning is limited during a mammography technologist's training. To address these issues, One World DMG is developing the MammoVest Simulator System, a device and curriculum designed to provide expanded initial training to mammography students and continuing education on proper positioning to practicing mammography technologists, ultimately to increase the efficacy of mammography screening. MammoVest will be a wearable vest with life-like female breasts and realistic elastic skin. The filler will mimic the real feel and response of breast tissue during manipulation and under compression. In this Phase I SBIR program we will first modify the initial design of the MammoVest, originally designed for mammography equipment demonstrations, to be wearable and have the optimal mobility and anatomy for breast positioning training. This first `Standard' MammoVest will provide mammography technologists with a dependable, standardized resource for beginner- level training. We will conduct a Face (or Content) Validity study in which expert mammography technologists will evaluate the realism of the `Standard' MammoVest with additional effort allotted to making any design modifications discovered to be necessary in the Validation study. Finally, we will develop and outline a downloadable curriculum for training breast positioning using MammoVest in collaboration with our expert mammography technologist. The curriculum will include videos of proper positioning, metrics for success, and common errors. This Phase I SBIR will demonstrate that MammoVest can be a complete, validated training system for mammography and breast positioning. In Phase II multiple MammoVests with diverse breast morphologies, including those most challenging to position (very large, very small, augmented, etc.), will be built, the curriculum expanded, and further Validation studies completed. Ultimately, MammoVest will provide standardized and validated breast positioning training to mammography technologists and radiologists, potentially improving the accuracy of mammography throughout the world.

项目摘要 美国约有12％的妇女一生将患乳腺癌，包括 估计有276,480例浸润性乳腺癌的新病例，48,350例非侵入性（原位）乳房病例 癌症和2020年的42,170例死亡。乳腺癌是女性中诊断出的第二大癌症， 死亡率仅次于肺癌。虽然乳房X线摄影是初始乳腺癌的黄金标准 筛查，乳房X线摄影可能会错过10-30％的乳腺癌。尽管有几个基础 解释，包括密集的乳房组织，生长缓慢的病变，感知误差和不正确的解释 在可疑发现中，乳房定位错误很常见，对 乳房X线摄影作为诊断方式的准确性。此外，定位错误是乳房的主要原因 中心失败了重新认证。这些问题源于以下事实：乳房定位的经验有限 在乳房X线摄影技术专家的培训中。为了解决这些问题，一个世界DMG正在发展 Mammovest模拟器系统，一种设备和课程，旨在提供扩展的初始培训 乳房X线摄影专业的学生和继续教育，以适当定位以实践乳房X线摄影 技术人员，最终提高乳房X线摄影筛查的功效。 Mammovest将是可穿戴的 带有栩栩如生的女性乳房和逼真的弹性皮肤。填充物将模仿 操纵期间和压缩过程中的乳房组织。在此阶段I SBIR程序中，我们将首先修改 最初是为乳房X线摄影设备演示设计的妈妈维斯特的初始设计， 可穿戴，并具有最佳的移动性和解剖学用于乳房定位训练。第一个“标准” Mammovest将为初学者提供可靠的标准化资源 - 水平培训。我们将进行一项面部（或内容）有效性研究，其中专家乳房X线摄影技术人员 将通过分配任何设计的额外精力来评估“标准”妈妈的现实主义 在验证研究中发现的修改是必要的。最后，我们将开发和概述 可下载的课程，用于与我们的专家合作使用Mammovest培训乳房定位 乳房X线摄影技术专家。该课程将包括适当定位的视频，成功指标以及 常见错误。 I阶段I SBIR将证明Mammovest可以是一个完整的，经过验证的培训 乳房X线摄影和乳房定位系统。在第二阶段，多种乳房的乳房 形态学，包括最具挑战性位置的形态（非常大，非常小，增强等）将是 建造，课程扩展，并完成了进一步的验证研究。最终，Mammovest将提供 标准化和经过验证的乳房X线摄影技术人员和放射学家的乳房定位训练， 有可能提高全世界乳房X线摄影的准确性。
