Claim 0:
1. A method for determining a presence of one or more congenital heart defects (CHDs) in a fetus during pregnancy, the method comprising:
determining, by a server, first image data representative of a portion of the fetus's cardiovascular system, the first image data comprising a series of image frames;
determining optical flow data based on the first image data, the optical flow data indicative of movement of pixels in the series of image frames;
processing the image data using a spatial model, the spatial model comprising one or more first convolutional neural networks trained to process image data;
processing the optical flow data using a temporal model, the temporal model comprising one or more second convolutional neural networks trained to process optical flow data;
generating a spatial output using the spatial model and based on the image data, the spatial output indicative of a first likelihood of a presence of one or more CHDs of the fetus, the spatial output comprising a matrix of values indicative of a view orientation in a respective image frame of the series of image frames;
generating a temporal output using the temporal model and based on the plurality of optical flow data, the temporal output indicative of a second likelihood of the presence of one or more CHD of the fetus;
determining a fused output based on the spatial output and the temporal output, the fused output indicative of a third likelihood of the presence of one or more CHDs of the fetus patient; and
causing a first device to display a user interface corresponding to the fused output.
