Neural Circuits

Neural Circuits

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Performance was compared against standard inversion algorithms.

Main Results:

The proposed neural network approach effectively compensated for modeling errors.
Significant improvements in ultrasound tomography image reconstruction quality were observed.
The method demonstrated efficacy even with relatively small training datasets.

Conclusions:

Neural network-based error compensation is a viable strategy for enhancing ultrasound tomography.
This approach offers a promising solution for achieving high-quality reconstructions with faster computations.
