The long term of the proposed research is to develop a dental radiography capable of reproducing a desired imaging geometry. The goals of the proposed research are to develop a prototype system and to test it on dry skulls. The patented robot control system (U.S. Patent #5, 113, 424) is capable of reproducing imagery geometry by sensing the 3-D position of the head using an electromagnetic sensor. A known X-ray source to tooth imaging geometry allows it to reposition the source in real-time to achieve this desired imaging geometry. In this way the imaging geometry can be reproduced without mechanical connection of the patient to the X-ray system. The advantage of such a system is the ability to produce radiographs of the entire mouth with a standardized imaging geometry that can used alone or for subtraction radiography to detect subtle change in the dentition. A system such as this can eventually be in place in a clinician's office. The goal of the proposed research is to demonstrate the feasibility of a prototype robot's controlled X-ray system. There are 2 specific aims. First, to develop a robot-controlled X-ray arm; second, to conduct trials with dry skulls, to determine if standardized films created with this system are a more accurate diagnostic tool. To achieve the first goal, an X-ray system will be modified and a study conducted to determine how accurately the arm can be repositioned. To achieve the second goal, radiographs will be taken on dry skulls. In this trial the robot control system will be compared to a subtraction system using occlusal stents. The anticipated outcome is that the robot control system will produce more diagnostically meaningful radiographs and subtraction images.

本研究的长期目标是开发一种牙科X线摄影技术， 能够再现所需的成像几何形状。 的目标 建议的研究是开发一个原型系统，并测试它的干 头骨 获得专利的机器人控制系统（美国专利#5，113，424）能够 通过使用传感器感测头部的3D位置来再现图像几何形状， 电磁传感器。 牙齿成像几何形状的已知X射线源 使其能够实时重新定位震源， 成像几何学 以这种方式，可以再现成像几何形状 而不需要将患者机械连接到X射线系统。 这样的系统的优点是能够产生所述组织的射线照片。 具有标准化成像几何结构的整个口腔， 用于减影X线摄影以检测牙列的细微变化。 一 诸如这样系统最终可以在临床医生的办公室中就位。 拟议研究的目标是证明一种 原型机器人的受控X射线系统 有两个具体目标。 第一，开发机器人控制的X光臂;第二，进行试验 用干燥的头骨，以确定是否标准化的电影与此创建 系统是更准确诊断工具。 为了实现第一个目标，将修改X射线系统，并进行研究 以确定如何准确的手臂可以重新定位。 到 为了实现第二个目标，将在干燥的头骨上拍摄X光照片。 在这 试验将机器人控制系统与减法系统进行比较 使用咬合支架。 预期的结果是机器人控制 系统将产生更多有诊断意义的射线照片， 减影图像
