MammoVest™ Simulator System and Curriculum for Initial and Continued Education in Mammography Positioning

项目摘要 在美国，大约12%的女性在一生中会患上乳腺癌，其中包括 估计有276，480例新的浸润性乳腺癌病例，48，350例新的非浸润性（原位）乳腺癌病例 癌症，2020年有42，170人死亡。乳腺癌是女性第二大诊断癌症， 死亡率仅次于肺癌。虽然乳房X光检查是早期乳腺癌的金标准， 在乳腺癌筛查中，10-30%的乳腺癌可能会在乳房X光检查中被遗漏。尽管有几个潜在的 解释，包括致密乳腺组织、缓慢生长的病变、感知错误和不正确的解释 在可疑的发现中，乳房定位的错误是常见的，并且对 乳房X光检查作为诊断方式的准确性。此外，定位误差是乳房畸形的主要原因。 中心未能重新认证。这些问题源于乳房定位的经验有限 在一个乳房X光检查技师的培训中。为了解决这些问题，One World DMG正在开发 MammoVest模拟器系统，一种旨在提供扩展初始培训的设备和课程， 乳房X线摄影学生和继续教育的正确定位，以实践乳房X线摄影 技术人员，最终提高乳房X光检查筛查的效率。MammoVest将是一款可穿戴设备， 背心与逼真的女性乳房和现实的弹性皮肤。填充物将模仿真实的感觉和反应， 在操作和压迫下的乳房组织。在第一阶段SBIR计划中，我们将首先修改 最初设计用于乳房X射线摄影设备演示的MammoVest的初始设计将 可穿戴，并具有最佳的流动性和解剖乳房定位训练。第一个“标准” MammoVest将为乳房X线摄影技术人员提供一个可靠的，标准化的资源，为初学者- 水平训练。我们将进行一项面部（或内容）有效性研究， 我将评估“标准”MammoVest的真实性，并分配额外的努力来进行任何设计 确认研究中发现的必要修改。最后，我们将制定并概述一个 与我们的专家合作，使用MammoVest培训乳房定位的可下载课程 乳房X光检查技师课程将包括适当定位的视频，成功的指标， 常见错误本第I阶段SBIR将证明MammoVest可以是一个完整的、经过验证的培训 用于乳房X线摄影和乳房定位的系统。在II期研究中，多个MammoVest（具有不同乳房） 形态，包括最难定位的形态（非常大、非常小、增大等），将 建立，课程扩展，并完成进一步的验证研究。最终，MammoVest将提供 对乳房X线摄影技术人员和放射科医生进行标准化和有效的乳房定位培训， 这可能会提高全世界乳房X光检查的准确性。

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.
