Acousto-Optic Tomography Reconstruction Library

AcoustoOpticTomography (AOT_biomaps)

AOT_biomaps is an advanced Python library for Acousto-Optic Tomography (AOT). It provides comprehensive tools for image reconstruction, acoustic simulation, optical modeling, and 2D/3D data processing.

📌 About the Project

This library was developed to meet the needs of the biomedical imaging research community, particularly for Acousto-Optic Tomography applications. It combines advanced reconstruction algorithms with optimized CPU and GPU implementations.

Key Features

• ✅ Tomographic Reconstruction: MLEM, PDHG, LS, DEPIERRO, MAPEM, LBFGS
• ✅ Multi-Device Support: CPU (NumPy) and GPU (CuPy) with automatic fallback
• ✅ Sparse Matrices: Optimized CSR and SELL-C-sigma implementations
• ✅ Acoustic Simulation: Plane, focused, irregular waves
• ✅ Optical Modeling: Lasers, absorbers, heterogeneous media
• ✅ Signal Processing: Filtering, backprojection, Radon transform
• ✅ Visualization: 2D/3D visualization tools (optional with matplotlib)

🎯 Quick Start Example

import numpy as np
from AOT_biomaps import Tomography, AlgebraicRecon
from AOT_biomaps.AOT_Recon.ReconEnums import ReconType

# Create a tomography experiment
experiment = Tomography(
    optic_image_path="path/to/optic_image.npy",
    acoustic_fields_path="path/to/acoustic_fields.npy"
)

# Setup reconstruction
recon = AlgebraicRecon(
    experiment=experiment,
    reconType=ReconType.Algebraic,
    optimizerType="MLEM",
    numIterations=100
)

# Run reconstruction
recon.run(withTumor=True)

# Save results
recon.save(withTumor=True, saveDir="results/")
