TECHNICAL ASSISTANCE FOR TELEVISION USE IN RESEARCH

电视系统已经成为许多科学和技术领域不可或缺的组成部分 在美国国立卫生研究院学习医学研究。一台电视机的实现 系统要求遵守严格的系统互连标准， 调整。BEIB应要求提供技术援助，例如 为校内研究提供制度设计和咨询 程序。咨询的范围从协助选择系统组件 例如相机、相关电子设备和镜头，以解决 一个现有的系统。一个典型的例子就是Dr。 史蒂文·斯坦霍普。 斯坦霍普博士有一台Vidicon六摄像头计算机操作的运动分析 用于获取和评估与患者相关的数据的系统 功能。视频系统检测反射标记的存在 定位在患者身上，并通过软件计算三维 每个标记的位置。持久力、开花结果和 摄像机的电子稳定性使六台摄像机保持平衡 非常困难。解决方案是用ccd取代摄像机。 摄像机。Ccd摄像头具有卓越的电子稳定性，并且不 当检测到快速运动时，显示图片涂抹。

Television systems have become an integral part of many scientific and medical research studies at the NIH. The implementation of a television system demands adherence to rigid standards for system interconnections and adjustments. On request, EEES, BEIB provides technical assistance such as system design and consultation is provided to the Intramural Research Program. Consultations range from assistance in selecting system components such as cameras, associated electronics, and lenses to solving problems of an existing system. A typical example is represented by the requests of Dr. Steven Stanhope. Dr. Stanhope has a Vidicon six camera computer operated motion analysis system for the acquisition and evaluation of data associated with patient function. The video system detects the presence of reflective markers located on the patient and by software, calculates the three dimensional location of each marker. The problems with persistence, blooming, and electronic stability of the vidicon makes the balancing of the six cameras very difficult. The solution is to replace the vidicon cameras with CCD cameras. The CCD cameras have superior electronic stability and do not display picture smearing when detecting fast motion.
