骨密度、骨龄计算机数字视频技术研究

APPLICATION OF COMPUTER DIGITAL VIDEO TECHNIQUE TO BONE MINERAL DENSITY AND BONE AGE

利用手骨影像转换器将不可见的手骨影像转变成电视模拟信号后输入计算机 ,然后再通过计算机将其转变成计算机数字信号。实现对手骨影像静止图像和动态画面的采集 ,并以计算机文件及数据光盘的方式长期记录和储存。为骨密度、骨龄资料的记录、分析和保存提供了快捷、准确、可行的方法。

The hand bone image exchanger was used to change invisible light into TV imitative signal turned into computer digital signal through a computer video card.The computer was used to realize the collection of static and dynamic hand bone images recorded and stored in files and data discs.The application of multimedia technique provided a speedy,accurate and practical method to recording,analyzing and storing data of bone mineral density (BMD) and bone age.
