  author={Piotr Jarosik and Michal Byra and Marcin Lewandowski and Ziemowit Klimonda},
Attenuation coefficient (AC) is a fundamental measure of tissue acoustical properties, which can be used in medical diag-nostics. In this work, we investigate the feasibility of using convolutional neural networks (CNNs) to directly estimate AC from radio-frequency (RF) ultrasound signals. To develop the CNNs we used RF signals collected from tissue mimicking numerical phantoms for the AC values in a range from 0.1 to 1.5 dB/(MHz*cm). The models were trained based on 1-D patches of RF data. We…

Speech acoustic modeling from raw multichannel waveforms

A convolutional neural network - deep neural network (CNN-DNN) acoustic model which takes raw multichannel waveforms as input, and learns a similar feature representation through supervised training and outperforms a DNN that uses log-mel filterbank magnitude features under noisy and reverberant conditions.

Paper presented at the 10th Nordic-Baltic Conference on Biomedical Imaging: Field: A Program for Simulating Ultrasound Systems

A program for the simulation of ultrasound systems is presented. It is based on the Tupholme-Stepanishen method, and is fast because of the use of a fareld approximation. Any kind of transducer

Convolutional neural networks for acoustic modeling of raw time signal in LVCSR

It is shown that the performance gap between DNNs trained on spliced hand-crafted features and DNN's trained on raw time signal can be strongly reduced by introducing 1D-convolutional layers.
