1. A computer-implemented method for determining fetal situs during an ultrasound imaging procedure, comprising:
obtaining, at an ultrasound machine having a display and at least one processor, an ultrasound image of a fetus in utero, the fetus including a torso and a spine, wherein the ultrasound image comprises a circumferential view of the torso of the fetus, and the circumferential view includes at least: (i) an outer border of the torso, and (ii) the spine that includes three landmarks arranged in a triangular orientation;
superimposing, at the ultrasound machine, a fetal overlay based on an alignment instruction corresponding to an alignment between the outer border of the torso and the three landmarks arranged in the triangular orientation to obtain an augmented reality image of the fetus, the fetal overlay including a graphical element indicating a left side and a right side of the fetus; and
outputting, on the display of the ultrasound machine, the augmented reality image of the fetus.
