From: Esmraldi: efficient methods for the fusion of mass spectrometry and magnetic resonance images
Overview of the proposed workflow. Steps for the fusion the fusion of a MRI (top row) and MALDI–MS (bottom row) images of a wheat grain. b The first step consists in extracting a representative shape through image reduction and segmentation. c The segmented shape in MALDI–MS is registered onto the MRI shape. This step involves linear and deformable registration methods. d Joint correlative analysis of the images: selection of the ion images in MALDI–MS which exhibit a similar spatial distribution as the distribution of water in MRI
