Biomagnetic field sensor systems and methods for diagnostic evaluation of cardiac conditions

A biomagnetic field sensor system for diagnostic evaluation of an individual, comprising:

• an array of biomagnetic field sensors configured to acquire electromagnetic field (EMF) signals associated with a tissue, an organ, or a body part of the individual and generate magnetic field measurements therefrom;
• a computer processor coupled to the array of biomagnetic field sensors;
• and
• a memory coupled to the computer processor, the memory storing instructions that are configured to be executed by the computer processor, the instructions, when executed by the computer processor, cause the biomagnetic field sensor system to:
• receive the EMF signals acquired by the array of biomagnetic field sensors;
• filter the EMF signals to obtain filtered data;
• execute a machine learning algorithm to process the filtered data, wherein the machine learning algorithm is trained to construct a hypothesis function according to training data comprising EMF measurements and corresponding abnormality data, to determine presence of one or more abnormalities in human subjects, the machine learning algorithm including a plurality of blocks of dilated convolutional neural networks, a respective block comprising a respective number of layers and a respective set of dilation rates, and wherein executing the machine learning algorithm includes:
• constructing, by the machine learning model, the hypothesis function based on the filtered data;
• determining, by the machine learning algorithm, whether an outcome of the hypothesis function is achieved;
• and
• determining, by the machine learning algorithm based on the outcome of the hypothesis function, whether an abnormality is present in the individual;
• and
• receive, as output via the machine learning algorithm, an analysis result indicating a presence or an absence of an abnormality of the tissue, the organ, or the body part of the individual, wherein the presence of the abnormality includes localization of the abnormality to a particular region of the tissue, organ, or body part.
