Stationary computed tomography (s‐CT) conceptually offers several advantages over existing rotating gantry‐based CT. Over the last 40 yr, s‐CT has been investigated using different technological approaches. We are developing a s‐CT system specifically for head/brain imaging using carbon nanotube (CNT)‐based field emission x‐ray source array technology. The noncircular geometry requires different assessment approaches as compared to circular geometries. The purpose of the present study is to investigate whether the CNT source array meets the requirements for stationary head CT (s‐HCT).

碳纳米管X射线源阵列在固定头计算机断层扫描中的评估

固定式计算机断层扫描（s-CT）从概念上讲比现有的基于龙门式旋转CT更具优势。在过去的40年中，使用不同的技术方法对s-CT进行了研究。我们正在使用基于碳纳米管（CNT）的场发射X射线源阵列技术开发专门用于头部/大脑成像的as-CT系统。与圆形几何形状相比，非圆形几何形状需要不同的评估方法。本研究的目的是调查CNT源阵列是否满足固定式头颅CT（s-HCT）的要求。
