密闭的电子元件、零件等内部的非破坏性检查,一般采用X射线TV装置,然而,具有复杂的内部结构及多层结构的零件中的检测则较为困难。同时,因利用断层图像进行检查,需要专用的昂贵的CT装置。因此,日本石川县工业试验场开发了小型零件用CT检查装置。它在X射线TV中增加了个人计算机、图像输入装置及回转控制装置,用软件处理X射线透视图像,再构成CT图像。该装置可用透视图像表示指定部位的断层图像,还能够用透视图像、断层图像两种图像进行检查。目前, X-ray TV devices are generally used for the non-destructive inspection of sealed electronic components, parts and the like. However, the detection of parts with complicated internal structures and multi-layer structures is more difficult. At the same time, due to the use of tomographic examination, a dedicated and expensive CT device is required. Therefore, Japan Ishikawa industrial test site has developed small parts CT inspection device. It X-ray TV in the increase of personal computers, image input devices and rotary control device, the software X-ray fluoroscopic images, and then constitute the CT images. The device can be used to express the perspective image of the designated site tomographic images, but also with perspective images, tomographic images of two kinds of inspection. Currently,
