Hyperspectral/Multispectral imaging (HSI/MSI) technologies are able to sample from tens to hundreds of spectral channels within the electromagnetic spectrum, exceeding the capabilities of human vision. These spectral techniques are based on the principle that every material has a different response (reflection and absorption) to different wavelengths. Thereby, this technology facilitates the discrimination between different materials. HSI has demonstrated good discrimination capabilities for materials in fields, for instance, remote sensing, pollution monitoring, field surveillance, food quality, agriculture, astronomy, geological mapping, and currently, also in medicine. HSI technology allows tissue observation beyond the limitations of the human eye. Moreover, many researchers are using HSI as a new diagnosis tool to analyze optical properties of tissue. Recently, HSI has shown good performance in identifying human diseases in a non-invasive manner. In this paper, we show the potential use of these technologies in the medical domain, with emphasis in the current advances in gastroenterology. The main aim of this review is to provide an overview of contemporary concepts regarding HSI technology together with state-of-art systems and applications in gastroenterology. Finally, we discuss the current limitations and upcoming trends of HSI in gastroenterology.
高光谱/多光谱成像（HSI/MSI）技术能够在电磁光谱范围内从数十个到数百个光谱通道进行采样，超越了人类视觉的能力。这些光谱技术基于每种材料对不同波长具有不同响应（反射和吸收）这一原理。因此，这项技术有助于区分不同的材料。HSI已在诸如遥感、污染监测、现场监视、食品质量、农业、天文学、地质测绘等领域以及目前在医学领域展现出对材料的良好辨别能力。HSI技术能够突破人眼的局限进行组织观察。此外，许多研究人员正在将HSI用作分析组织光学特性的新型诊断工具。最近，HSI在以非侵入性方式识别人类疾病方面表现出良好性能。在本文中，我们展示了这些技术在医学领域的潜在用途，重点介绍了胃肠病学的当前进展。本综述的主要目的是概述有关HSI技术的当代概念以及胃肠病学领域的最新系统和应用。最后，我们讨论了HSI在胃肠病学中的当前局限性和未来趋势。
