Data associated with the publication: Multi-contrast laser endoscopy for in vivo gastrointestinal imaging

This repository contains data and code for replicating the data analysis presented in <i>Multi-contrast laser endoscopy for in vivo gastrointestinal imaging.</i> In this project, we introduce a Multi-contrast Laser Endoscopy (MLE) system with rapidly tunable spectral, coherent, and directional illumination. We demonstrate three capabilities of MLE: enhancing tissue chromophore contrast with multispectral diffuse reflectance, quantifying blood flow using laser speckle contrast imaging, and characterizing mucosal topography using photometric stereo. We validate MLE with benchtop models, then demonstrate MLE in vivo during clinical colonoscopies. The data collection is split into code and data subdirectories. Due to the larger file sizes, the dataset cannot be downloaded as a single combined .zip file, and so should be downloaded individually. Please refer to the README for instructions for reassembling the file directly organization for proper file path access by the code.
