1. A system for diagnosing and assessing the severity of plagiocephaly based on a quantification of the asymmetry in the cranial contour of an infant subject's head, the system adapted to:
receive a set of images of a top of an infant subject's head;
select an image from the set of images having an accurate representation of the top of the infant subject's head;
utilize the selected image for tracing an outline of a cranial contour of the infant subject's head;
quantify a degree of asymmetry in the cranial contour;
locate a center of the infant subject's head to find an initial radius for the infant subject's cranial contour;
identify an optimal cranial contour by iteratively updating the contour points;
calculate radial distances from the located center of the infant subject's head to specified points on the infant subject's cranial contour;
calculate an assessment of plagiocephaly severity based on the calculated radial distances; and
output a diagnosis of plagiocephaly including a level of severity.
