Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Electron Microscope Tomography and Single-particle Reconstruction

Electron Microscope Tomography and Single-particle Reconstruction

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Validation through numerical simulations.
Experimental validation using phantom studies.

Main Results:

The proposed 3D model-based inversion algorithm significantly improves image reconstruction quality.
Demonstrated superior performance compared to commonly-used backprojection algorithms.
Numerical simulations and phantom experiments confirmed the algorithm's effectiveness.

Conclusions:

The developed model-based inversion algorithm offers accurate 3D optoacoustic image reconstruction.
This approach overcomes limitations of reduced-dimensionality methods, enhancing image contrast and resolution.
The algorithm represents a significant advancement for quantitative optoacoustic imaging applications.
