项目摘要

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.

拟议研究的长期目标是开发牙科放射线照相术能够再现所需的成像几何形状。的目标拟议的研究是开发一个原型系统并在干环境中进行测试头骨。获得专利的机器人控制系统（美国专利#5、113、424）能够通过感测头部的 3D 位置来再现图像几何形状电磁传感器。已知的 X 射线源到牙齿成像几何形状允许它实时重新定位源以实现这一期望成像几何。通过这种方式可以再现成像几何形状无需将患者与 X 射线系统进行机械连接。这种系统的优点是能够生成射线照片整个口腔具有标准化的成像几何形状，可以单独使用或用于减影射线照相以检测牙列的细微变化。一个这样的系统最终可以在临床医生的办公室就位。拟议研究的目标是证明可行性原型机器人的受控 X 射线系统。有 2 个具体目标。一是开发机器人控制的X射线臂；二、进行试验用干燥的头骨，以确定是否用此制作标准化电影系统是更准确的诊断工具。为了实现第一个目标，将修改 X 射线系统并进行研究进行以确定手臂重新定位的精确度。到为了实现第二个目标，将在干燥的头骨上拍摄射线照片。在这个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具诊断意义的射线照片减法图像。
