For radiological technologists, it is very important to understand the principle of computed tomography (CT) and CT artifacts derived from mechanical and electrical failure. In this study, a CT system for educating radiological technologists was developed. The system consisted of a cone-beam CT scanner and educational software. The cone-beam CT scanner has a simple structure, using a micro-focus X-ray tube and an indirect-conversion flat panel detector. For the educational software, we developed various educational functions of image reconstruction and reconstruction parameters as well as CT artifacts. In the experiments, the capabilities of the system were evaluated using an acrylic phantom. We verified that the system produced the expected results.
对于放射技师来说，了解计算机断层扫描（CT）的原理以及由机械和电气故障产生的CT伪影非常重要。在本研究中，开发了一种用于培训放射技师的CT系统。该系统由一台锥束CT扫描仪和教育软件组成。锥束CT扫描仪结构简单，采用微焦点X射线管和间接转换平板探测器。对于教育软件，我们开发了各种图像重建、重建参数以及CT伪影的教育功能。在实验中，使用丙烯酸体模对系统的性能进行了评估。我们验证了该系统产生了预期的结果。
