Abstract
Methods, apparatus, and storage medium for obtaining high-resolution mass spectra and chemical maps from a sample using a subspace Fourier transform mass spectrometry (FT-MS) approach are described. The method includes conducting a first set of image data corresponding to a first group of spatial positions on the sample and a second set of image data corresponding to a second group of spatial positions on the sample; conducting a decomposition process on the first set of image data to obtain a set of basis elements; performing a reconstruction process on a second set of image data to obtain a set of reconstructed image data; performing a Fourier transform on the first and second sets of image data to obtain a first and second sets of mass spectra, respectively; and obtaining a FT-MS image for the sample based on the first set of mass spectra and the second set of mass spectra.
