Development of CT needle aspiration navigation system using multi-slice CT fluoroscope

随着CT透视技术和多层螺旋CT扫描技术的发展，我们可以进行多层面的CT扫描。然而，目前使用的多显示器的方法很难立即识别针尖的三维位置，因为我们无法同时观察多个图像。为了克服这个问题，我们开发了一种新的多层CT荧光镜彩色显示方法和针吸辅助系统。此外，我们还利用投影映射技术开发了一种新的显示方法。它是一种层投影映射技术，通过彩色显示方法和层投影映射技术，可以实现高准确性、高安全性、低患者和操作者辐射剂量的CT针吸检查。

Developments in CT fluoroscope technology and multi slice CT scanning have enabled us to conduct CT scanning in multi sections. However, the current method used with multiple displays makes it difficult to recognize the needle point's three-dimensional location instantly, because we are unable to observe multiple images simultaneously. To overcome this problem, we have developed a new color display method and needle aspiration assistance system for multi slice CT fluoroscope. In addition to this, we have developed the new display method by using projection mapping technique. It is slice projection mapping.By using color display method and slice projection mapping method, we could carry out the CT needle aspiration with high accuracy, high safety and low radiation dose of the patient and the operator.
