Claim 0:
1. A method of analyzing images obtained from an echocardiogram, the method comprising performing by a computer system:
receiving the images obtained from the echocardiogram;
identifying a subset of images corresponding to a particular echo view of a heart using a first convolutional neural network, wherein each image of the subset of images includes a set of pixel values, and wherein the particular echo view is selected from a group consisting of apical 2-, 3-, and 4-chamber (A2c, A3c, and A4c), parasternal long axis (PLAX), parasternal short axis (PSAX), and inferior vena cava (IVC);
feeding the sets of pixel values into a second convolutional neural network trained using sample echocardiograms with at least two different structures identified;
for each pixel of each image of the subset of images, assigning a probability of the pixel being part of one of a plurality of structures using the second convolutional neural network, wherein at least one of the plurality of structures is part of the heart imaged in the echocardiogram;
identifying pixels in each of the images that correspond to a first structure of the heart based on a comparison of the probabilities to a threshold; and
providing an indication of the first structure in the subset of images.
