摘要:

机器学习技术正越来越多地应用于医学与物理科学的各类成像模态中;然而,开发这类工具时的一个重要问题是高质量训练数据的可用性。本文提出了一个独特的多模态同步辐射数据集,样本为定制的锌掺杂Zeolite 13X(沸石13X),可用于开发先进的深度学习与数据融合流程。研究首先对一块锌掺杂Zeolite 13X碎片开展了多分辨率显微X射线计算机断层扫描,以表征其孔隙与特征,随后进行了空间分辨X射线衍射计算机断层扫描,以表征钠相和锌相的均匀分布。研究通过控制锌的吸收,制备出了一种简单的、空间隔离的两相材料。原始数据与处理后数据均以一系列Zenodo条目形式公开。总体而言,本文提出了一个空间分辨的三维多模态多分辨率数据集,可用于机器学习技术的开发,适用场景包括超分辨率、多模态数据融合以及三维重建算法的开发。

英文摘要:

Machine learning techniques are being increasingly applied in medical and physical sciences across a variety of imaging modalities; however, an important issue when developing these tools is the availability of good quality training data. Here we present a unique, multimodal synchrotron dataset of a bespoke zinc-doped Zeolite 13X sample that can be used to develop advanced deep learning and data fusion pipelines. Multi-resolution micro X-ray computed tomography was performed on a zinc-doped Zeolite 13X fragment to characterise its pores and features, before spatially resolved X-ray diffraction computed tomography was carried out to characterise the homogeneous distribution of sodium and zinc phases. Zinc absorption was controlled to create a simple, spatially isolated, two-phase material. Both raw and processed data is available as a series of Zenodo entries. Altogether we present a spatially resolved, three-dimensional, multimodal, multi-resolution dataset that can be used for the development of machine learning techniques. Such techniques include development of super-resolution, multimodal data fusion, and 3D reconstruction algorithm development.
