Intraoral radiography is important for not only diagnosis but also national dose reduction. The development of computer technology gives us a modern virtual reality system. In this study, we develop intraoral radiography training system in virtual reality (VR) and its effectiveness was evaluated.We decided to use the Omega Space (Solid ray, Japan) because its handling capacity of VR contents and easy operability. CT data of a dry skull was used in VR content. The simulated x-ray displayed in a few seconds.The questionnaire survey was performed on the students of dental school. The VR system offered better effect on understanding of the effect of angulation of x-ray source on the radiography. For the evaluation of images, we used subtraction method. in this methods moved distance calculated from images were good correlated with actual difference of the images.

口内X光检查不仅对诊断很重要，而且对国家剂量减少也很重要。计算机技术的发展给我们带来了现代虚拟现实系统。在本研究中，我们开发了虚拟现实（VR）中的口腔内放射成像训练系统，并对其有效性进行了评估。我们决定使用Omega Space（Solid ray，日本），因为它的VR内容处理能力强且易于操作。 VR 内容中使用了干燥头骨的 CT 数据。模拟X射线在几秒钟内显示出来。对牙科学校的学生进行了问卷调查。 VR系统对于了解X射线源角度对射线照相的影响提供了更好的效果。对于图像的评估，我们使用减法方法。在该方法中，从图像计算出的移动距离与图像的实际差异具有良好的相关性。
