Mass Spectrometry Imaging

Mass spectrometry imaging (MSI) is a powerful technique used to visualize the spatial distribution of molecules within a sample, providing crucial insights into biological processes and disease. Current research focuses on improving MSI efficiency through advanced sampling strategies, such as deep learning-based dynamic sampling, which significantly reduces acquisition time by prioritizing informative regions. Furthermore, sophisticated data analysis methods, including topological data analysis, are being developed to enhance signal processing, improve noise reduction, and enable more robust classification of complex biological features, such as tumor subtypes. These advancements are expanding the applications of MSI in diverse fields, including cancer research and drug discovery.
