Electrical Impedance Tomography (EIT) is a noninvasive imaging technique for estimating conductivity distributions, but its inverse problems are computationally demanding and noise-sensitive. This paper presents a deep learning framework integrating classification andregression to estimate conductivity maps efficiently. The model employs MobileNetV2-inspiredresidual blocks in a U-Net-based encoder-decoder structure. regression is handled by weighting class probabilities with a predefined conductivity scale. Evaluated on simulated andreal EIT data, the model accurately reconstructs conductivity maps, offering an efficient, real-time solution for biomedical and industrial imaging.

This article presents the development of two innovative medical devices: a cheap ultrasound tomography (UST) system that uses beamforming technology for imaging and an electrical impedance tomography (EIT) system. Combining these two technologies allows for the creation of a hybrid tomography system that uses novel algorithms to monitor the lower urinary tract. The information obtained from this system is intended to be used to detect diseases early and present them to medical personnel to contribute to diagnosing anddetecting diseases. Methods: The UST system utilizes beamforming technology to focus and steer ultrasound waves to produce images of the body's internal organs and tissues. The EIT system uses low-frequency electrical currents to image the body's electrical conductivity. Combining these two technologies allows for a hybrid tomography system that uses novel algorithms to monitor the lower urinary tract. Findings: The information obtained from the hybrid tomography system is intended to be used to detect diseases early and present them to medical personnel to contribute to diagnosing anddetecting diseases. The system is expected to be particularly useful fordetecting diseases related to the lower urinary tract.

This paper presents biomedical time series from Body Surface Potential Mapping (BSPM) recognition using various convolutional andrecurrent neural network structures. The BSPM signal is in a form of time series form 102 channels located around the chest. The time series are then transformed to time windows to allow recognition of heart diseases. The several options of neural network structures were compared: one-dimensional convolutional neural network, Long-Short-Term Memory neural network, and Gatedrecurrent Unit neural network. The article showcases different convolutional andrecurrent neural network architectures forrecognizing patterns in biomedical time series measured with Body Surface Potential Mapping. The study compared three types of neural network structures: Long-Short-Term Memory neural network, Gatedrecurrent Unit neural network, and one-dimensional convolutional neural network. The main goal of paper is to find optimal machine learning solution for heart disease recognition on the basis of BSPM signal. The best results are obtained using model with GrU layer.
