Abstract: Devices, systems, and methods for automated segmentation and slicing of cardiac computed tomography (CT) images are described. An example method includes receiving a first plurality of input image frames associated with a cardiac CT operation, each of the first plurality of input image frames comprising a representation of two or more chambers of a heart, and performing, using a convolutional neural network, a segmentation operation and a slicing operation on each of the first plurality of input image frames to generate each of a plurality of output image frames comprising results of the segmentation operation and the slicing operation, wherein the segmentation operation comprises identifying volumes of each of the two or more chambers of the heart based on blood volumes, wherein the slicing operation comprises identifying one or more features of the heart in at least one predefined plane in a coordinate system associated with the cardiac CT operation.
