项目摘要

DESCRIPTION (provided by applicant): The National Institute on Deafness and Other Communication Disorders (NIDCD) supports research and development of innovative technologies for improving the quality and utilization of hearing aid devices. Physical Optics Corporation proposes development of a new Ear Canal Optical Coherent Tomography (ECOCT) system to obtain the shape of the individual ear canal and the corresponding 3-D image of the underlying tissue by a purely optical means, without taking an ear canal imprint. This innovative system will improve the accuracy of ear canal shape measurements (to better than 10 5m), and provide a unique opportunity of using a 3-D map of the underlying tissue to help eliminate the excess pressure from the hearing aid shell impinging on the most sensitive areas in the ear canal. The digital file obtained by the ECOCT system will be sent to the hearing aid manufacturer through the Internet, and will be easily archived or stored on a personal memory stick. Manufacturing cost savings will be achieved through reduction of the shell re-work to obtain a perfect fit into the ear canal. In Phase I, POC will design, fabricate, assemble, and test the laboratory prototype, and demonstrate its major operational parameters (accuracy of measurements, speed of operation, capability of mapping underlying tissue, etc.) In Phase II, POC will design and fabricate a fully operational prototype and test its operation on a representative pool of patients at the House Ear Institute in Los Angeles, California. PUBLIC HEALTH RELEVANCE: Approximately 36 million American adults report some degree of hearing loss and would benefit from hearing aid use. However, only ~20 percent of potential hearing aid candidates actually use these devices, owing to concerns about inconvenience, discomfort, stigma, cosmetics, sound quality, and affordability. The conventional method of design of the individual hearing aid shell involves taking imprints of the ear canal using various types of impression materials, and sending it to a hearing aid manufacturer, where the imprint shape is measured by a 3-D laser scanner for subsequent computer assisted shell design. The step of making imprints is the major source of mistakes and the need for rework in hearing aid manufacturing, causing significant cost increases for hearing aid devices and disappointment with the sound quality, as well as discomfort for patients. The Ear Canal Optical Coherent Tomography (ECOCT) system will provide a digital 3-D shape of individual ear canals by a purely optical means, with better accuracy, while enabling mapping of the underlying tissue to improve shell fit into the ear canal. The digital file of the ear canal shape and the map of the underlying tissue obtained at the primary care provider's office will be easily sent to the shell manufacturer, and archived or stored on a personal memory stick. The ECOCT technology will reduce the hearing aid cost (by decreasing the rework to get a better fit), and improve the sound quality, convenience, and comfort of hearing aid use.

描述（由申请人提供）：美国国家耳聋和其他沟通障碍研究所 (NIDCD) 支持创新技术的研究和开发，以提高助听器的质量和利用率。物理光学公司提议开发一种新的耳道光学相干断层扫描 (ECOCT) 系统，通过纯光学手段获得个体耳道的形状和相应的底层组织的 3D 图像，而无需留下耳道印记。这一创新系统将提高耳道形状测量的准确性（优于 10 5 m），并提供使用底层组织 3-D 图的独特机会，以帮助消除助听器外壳撞击耳道的过大压力。耳道中最敏感的区域。 ECOCT系统获得的数字文件将通过互联网发送给助听器制造商，并可以轻松存档或存储在个人记忆棒上。通过减少外壳返工以获得与耳道的完美贴合，可以节省制造成本。在第一阶段，POC 将设计、制造、组装和测试实验室原型，并演示其主要操作参数（测量精度、操作速度、绘制底层组织的能力等）。在第二阶段，POC 将设计和测试实验室原型。制造一个完全可操作的原型，并在加利福尼亚州洛杉矶的 House Ear Institute 的代表性患者池中测试其操作。公共卫生相关性：大约 3600 万美国成年人报告有一定程度的听力损失，他们将受益于助听器的使用。然而，由于担心不便、不适、耻辱、美观、音质和负担能力，只有约 20% 的潜在助听器候选人实际使用这些设备。个体助听器外壳的传统设计方法包括使用各种类型的印模材料获取耳道的印记，并将其发送给助听器制造商，在那里通过 3D 激光扫描仪测量印记形状以供后续计算机使用辅助外壳设计。制作印记的步骤是助听器制造过程中出现错误和返工的主要来源，导致助听器设备的成本大幅增加、对音质的失望以及患者的不适。耳道光学相干断层扫描 (ECOCT) 系统将通过纯光学手段提供个体耳道的数字 3D 形状，具有更高的精度，同时能够对底层组织进行绘图，以改善外壳与耳道的贴合度。在初级保健提供者办公室获得的耳道形状的数字文件和下面组织的图将很容易发送给外壳制造商，并存档或存储在个人记忆棒上。 ECOCT技术将降低助听器成本（通过减少返工以获得更好的适配），并提高助听器使用的音质、便利性和舒适度。
