The present case study critically assesses the efficacy of a previously proposed segmentation methodology as a means to discriminate phases post-processing the image of an elemental map. In the BiTeS multiphase compound, the reference spectra of the BiTe and BiTeS phases are distinct enough to effectively distinguish two phases during map acquisition. Since the counts of the sulphur-K peak in the X-ray emission data are significantly higher for BiTeS compared to BiTe, the segmentation methodology exploits this variation and enables successful phase discrimination post-processing the image of the elemental map.
本案例研究严格评估了先前提出的一种分割方法的有效性，该方法用于在对元素图图像进行后处理时区分不同相。在BiTeS多相化合物中，BiTe相和BiTeS相的参考光谱足够不同，能够在图谱采集过程中有效区分这两个相。由于与BiTe相比，BiTeS的X射线发射数据中硫-K峰的计数显著更高，该分割方法利用了这种差异，并能够在对元素图图像进行后处理时成功实现相区分。
