Gestational age estimation from the measurements of the fetal head from the ultrasound images can be of great importance in management decisions during pregnancy. Biparietal diameter (BPD), occipital frontal diameter (OFD), and the head circumference (HC) are the most common parameters used for estimating the gestational age. Since the fetal head has an elliptical shape in the two dimensional image plane, extracting the ellipse and measuring the major axis (OFC), minor axis (BPD), and circumference (HC) are the task of image processing which will be discussed in this paper. |
