Abstract
The slice geometry of the EMI head scanner is investigated. It is shown that the slice thickness is positionally dependent. The slice is thinner in the central part than on the periphery and also thinner on the tube side than on the detector side. It is also shown that there is a missing region between slices A and B.
摘要
对EMI头部扫描仪的切片几何形状进行了研究。结果表明，切片厚度与位置有关。切片在中心部分比在外围更薄，并且在管侧比在探测器侧更薄。还表明，在切片A和B之间存在一个缺失区域。
