曲面断层牙片机成像载体支架的改进研究

目的：介绍一种简便实用的数字牙片摄影装置。方法：采用PanouraUIJTRA曲面断层牙片机设备，将曲面断层牙片机的成像载体支架轴承杆和胶片盒手柄位置进行改进，使其支持把传统增感屏一胶片，改为装载数字X线成像IP板进行摄片。用FCR5000R读取器对IP板进行读取，再经终端处理器对所获图像进行计算机后处理，最后用FUJI-FILM DRY PIX7000激光相机打印，从而得到一张高清晰、高质量的数字牙片。结果：利用改进后的成像载体支架进行曲面断层摄影，甲片率达98％以上。结论：该装置具有设计合理、操作简便、成本低廉、节能环保、成像质量好、辐射计量小、可软读片、并入PACS方便远程会诊等特点，在口腔临床及科研教学方面有良好的应用前景。

Improvement of Image Carrier Bracket of Orthopantomograph Dental Machine

Objective To introduce a kind of simple and practical digital dental photographic equipment. Methods PanouraULTRA Orthopantomograph dental equipment was adopted to improve its axletree pole of imaging carrier bracket and the position of the handle of film box, so as to make it possible to change the traditional screen film into the IP board carrying digital X-ray imaging to take pictures. By reading the IP board with FCR5000R read implement, dealing with the acquired images through terminal processor, and then using FUJIFILM DRY PIX7000 laser camera to print, a highly clear digital tooth image with high quality would be got. Results Taking Orthopantomograph photos with the improved imaging carrier bracket, successful photos were over 98% of the total. Conclusion This applied machine is characterized by several advantages as follows: appropriate design, convenient operation, low cost, energy-saving and environment protection; high quality of imaging and low quantity of radiation. It can be combined with PACS, which is convenient for distant consultation. This equipment has a promising future in the fields of clinical oral cavity, scientific research and teaching.
