The main of this work is to determine the elemental distribution in breast and prostate tissue samples in order to verify the concentration of some elements correlated with characteristics and pathology of each tissue observed by the X-ray transmission microtomography (microCT). The experiments were performed at the X-ray fluorescence beamline of the Brazilian Synchrotron Light Laboratory. The microCT images were reconstructed using a filtered-back-projection algorithm and the XRF microtomographies were reconstructed using a filtered-back-projection algorithm with absorption corrections.
这项工作的主要目的是确定乳腺和前列腺组织样本中的元素分布，以便通过X射线透射显微断层扫描（显微CT）验证与每个组织的特征和病理学相关的某些元素的浓度。实验在巴西同步加速器光实验室的X射线荧光束线进行。显微CT图像使用滤波反投影算法重建，X射线荧光显微断层扫描使用带有吸收校正的滤波反投影算法重建。
