本文对双采样X射线层析成像的感兴趣区域进行了详细的误差分析。模拟研究与一系列采样率沿着使用，以量化感兴趣区域内的采样误差量。它示出，作为感兴趣的区域外的采样率变得稀疏的感兴趣的区域内的采样误差的量大大增加。
A detailed error analysis for the dual-sampling region-ofinterest X-ray tomography is presented. Simulation studies are used along with a range of sampling rates to quantitate the amount of sampling errors within the region of interest. It is shown that as the rate of sampling outside the region of interest becomes sparse the amount of sampling errors within the region of interest increases considerably.
