Title:
SYSTEM AND METHOD FOR NEONATAL ELECTROPHYSIOLOGICAL SIGNAL ACQUISITION AND INTERPRETATION
Document Type and Number:
WIPO Patent Application WO/2022/122772
Kind Code:
A3
Abstract:
The present invention relates to an integrated system and method for EEG signal acquisition and interpretation, for neonatal seizure detection. The system as per the present invention comprises a control device, an integrated circuit, a wireless communication module, a visual indication means, and a power management module. The control device has a Convolutional Neural Network (CNN) embedded on it, and is programmed to configure the integrated circuit to receive a plurality of channels of EEG data from a plurality of EEG acquisition electrodes, and to amplify and digitize the received EEG data. The integrated circuit is further configured to segment the channels of EEG data to a plurality of sequential epochs of EEG data. The control device is configured to pass the sequential epochs of EEG data through the CNN which is pre-trained to output the probability of a seizure in the EEG data passed through it. The channels of EEG data received from the acquisition electrodes and the probability of seizure outputted by the CNN is communicated to at least remote computing device by the communication module. A filter is applied to smooth the outputs in a post-processing routine. The visual indication means is enabled if the output of the CNN exceeds a predetermined threshold probability.
