quantEM is an open source Python toolkit for quantitative electron microscopy: imaging, diffraction, ptychography, tomography, and spectroscopy. Built on PyTorch, it runs on CPUs and GPUs and integrates deep learning.
🚀 Get started
What quantEM is, how to install it, and how the package is organized.
🔬 Imaging
Drift correction and lattice analysis for atomic resolution images.
💠 Diffraction
Bragg disk detection, model fitting, and strain mapping for 4D-STEM.
🌀 Diffractive imaging
Iterative and direct ptychography, from quick previews to multi-GPU reconstructions.
🧊 Tomography
Alignment, preprocessing, and 3D reconstruction of tilt series.
🌈 Spectroscopy
Analysis of spectroscopic signals such as EDS.
quantEM is developed openly on GitHub, with worked examples in quantem-tutorials. It is free software under the MIT license.
