Adaptive Voronoi Binning in Muon Radiography for Detecting Subsurface Cavities

Muon radiography is an advanced imaging technique that utilizes cosmic muons to visualize the interior of structures and materials, making it highly valuable for subsurface investigations. In this study, we present a measurement conducted using muon radiography at the Temperino mine. We demonstrate the application of an adaptive binning approach using Voronoi tessellation to enhance image visualization and improve cavity detection. The results reveal that the adaptive binning technique significantly improves the visibility of regions with cavities. The combination of muon radiography and adaptive binning through Voronoi tessellation showcases its potential as a powerful tool for subsurface exploration and geological studies, providing a more accurate and reliable approach for cavity detection and characterization.
