本文研究了空间分辨率和探测器相对方位对双探测器康普顿相机定向定位精度的影响。我们推导出一个将角不确定性与空间分辨率和几何关系起来的一般表达式。作为一般表达式的特殊情况，可以得到特定构型的适当表达式。最后，我们给出了一个简单的公式来估计相对空间分辨率和距离的康普顿凸轮时代的位置不确定性。
In this paper, we investigate the effects of spatial resolution and relative orientation of detectors on the accuracy of the directional localization in two-detector Compton cameras. We derive a general expression that relates the angular uncertainty to spatial resolution and geometry. Appropriate expressions for specific configurations are obtained as special cases of the general expression. Finally, we present a simple formula for estimating the position uncertainty of Compton cam eras in terms of relative spatial resolution and distances.
