1. A method of examining fetal hearts and identifying normality or abnormality of fetal hearts, comprising:
obtaining spatiotemporal image correlation ultrasound data of a fetal heart of a subject to generate a plurality of fetal heart images at different cardiac phases;
displaying different marked sample images of a sample fetal heart and at respective cardiac phases, the different marked sample images each marking a different feature of the sample fetal heart at a respective marked location;
sequentially presenting one of the different marked sample images to a user along with one of the fetal heart images;
as each of the different marked sample images is sequentially presented, prompting the user to mark the different feature in a respective fetal heart image based on its marked location in the different marked sample image, to create a plurality of marked fetal heart images;
reconstructing a unique geometric model of the fetal heart based on the marked fetal heart images, from which fetal echocardiography views can be extracted; and
displaying the fetal echocardiography views of the fetal heart.
