Intra-oral radiography is used frequently in dentistry. The quality of radiograph influences on diagnosis. The quality of intra-oral radiography is mostly affected by the skill of radiographers. In the course of clinical training of the students of dental school, it is important to train the technique of intra-oral radiography. So in this experiments we conducted to make up the training system of taking the intra-oral radiography with virtual reality.Research was divided in the next three stages:1. Examine the most appropriate data on the tooth and jaw bones for the use of the simulation.2. Clear the feeling of the virtual reality system for the students.3. Build up the program, which simulates an intra-oral X-rays, image and examine its precision.ResultsThe data obtained from cone beam CT is best for the simulation because the spatial resolution of that is most high and easy of data conversion.As for a feeling of the use of the virtual space, it was a comparatively good result as for the three dimensional effect.The program, which simulated images of intra-oral radiography, was made using Visual Basic. That simulation image was high precision comparatively.The unresolved problems are the time until an image was made which was long with about five minutes, and the image resolution was not good at original intra-oral radiograph. It could think about the computer system of the higher ability with the necessity to solve these problems.

口腔内放射照相术在牙科中经常使用。X线片的质量影响诊断。口内放射摄影的质量很大程度上受放射技师技术的影响。在口腔专科学生的临床实习过程中，口内摄片技术的训练是非常重要的。因此，本实验进行了构建虚拟现实口腔内摄影训练系统的研究。检查最合适的数据上的牙齿和颌骨的使用模拟。2.明确学生对虚拟现实系统的感受.结果锥形束CT的空间分辨率最高，数据转换容易，模拟结果最好，虚拟空间的使用感和三维效果也比较好，模拟口腔X线摄影图像的程序，是用Visual Basic做的。该模拟图像精度较高，但仍存在成像时间较长（约5分钟），图像分辨率不高等问题。解决这些问题的必要性促使人们思考更高性能的计算机系统。
