Difference of Gaussians revolved along elliptical paths for ultrasound fetal head segmentation

Ultrasound measurements of fetal biometry is a standard method for dating pregnancies and for assessment of fetal growth. Standard biometric measurements include biparietal diameter (BPD), occipito-frontal diameter (OFD), head-circumference (HC), abdominal circumference (AC), crown-rump length (CRL) and femur length (FL). Based on these measurements, the gestational age and size of the fetus can then be estimated using charts or regression formulae [5,15,8]. In particular, biometrics related to the fetal head, i.e., BPD and HC as shown in Fig.
