THREE DIMENSIONAL VIDEO CAMERA FOR PLASTIC SURGERY

人体表面的形状本质上是三维的，而所有传统的摄影设备和相机只能获取二维的平面图像。这一基本限制极大地限制了整形外科医生测量患者体表真实三维形状的能力；它阻碍了对困难的美学或重建问题的定量评估和准确记录。本文提出的SBIR努力的主要目标是开发一种新型、高速、低成本、非侵入性和多功能的3D摄像机硬件/软件，该硬件/软件能够获取患者体表的全帧3D图像。定量的3D测量数据使整形外科医生能够进行高保真的手术前预测、手术后监测和计算机辅助程序设计。3D摄像机捕获的2D和3D图像将允许外科医生和患者通过使用实际的2D/3D图像和计算机生成的交替来讨论手术计划过程。直接的术前视觉沟通通过改善患者对现实结果的教育，有助于提高术后满意度。3D可视交流在主治医生和住院外科医生之间的住院医生和同伴教学项目中也可能是无价的。拟议的商业应用：拟议的3D成像技术为许多医学成像和可视化应用增加了一个维度(字面上和比喻上)。如果成功，它将对生物医学研究产生重大影响，并将彻底改变目前在整形和重建外科、身体畸形、康复、住院医师培训和教育方面的许多做法。它将在矫形术和假肢中发挥作用，在这些领域可以生产出更合适的支架和假肢。

The shape of human body surface is three-dimensional (3D) in nature, yet all conventional photography devices and cameras can only acquire two- dimensional flat images. This fundamental restriction greatly limited the capability of plastic surgeons- in measuring true three-dimensional shapes of patient's body surface; It prevents the quantitative evaluation and accurate documentation of difficult aesthetic or reconstructive problems. The primary objective of the SBIR effort proposed herein is to develop a novel, high-speed, low-cost, non-invasive, and versatile 3D video camera hardware/software that is able to acquire full frame 3D images of patient's body surface. The quantitative 3D measurement data enables plastic surgeons to perform high-fidelity pre-surgical prediction, post-surgical monitoring, and computer-aided procedure design. The 2D and 3D images captured by the 3D video camera would allow the surgeon and the patient to discuss the surgical planning process through the use of actual 2D/3D images and computer-generated alternations. Direct preoperative visual communication helps to increase postoperative satisfaction by improving patient education in regards to realistic results. The 3D visual communication may also be invaluable in resident and fellow teaching programs between attending and resident surgeons. PROPOSED COMMERCIAL APPLICATIONS: The proposed 3D imaging technology adds one more dimension (literally and figuratively) to many medical imaging and visualization applications. If successful, it will have a significant impact on biomedical research and will revolutionize many current practices in plastic and reconstructive surgery, body deformities, rehabilitation, resident training and education. It would find utility in orthotics and prosthesis, where better-fitting braces and artificial limbs could be produced.
