The Model 068 contains an asymmetric head with upper portion of the skull, right and left brain lobes and lateral and third ventricles. These anatomical references are used to measure the biparietal diameter (BPD) and anterior/posterior diameter (APD). Right and left femoral shafts with distal epiphysis are provided for femur length (FL) measurements. An umbilical marker indicates proper position for taking abdominal circumference (AC). Crown-Rump length (CRL) can also be taken. In addition, the model has full facial details making it suitable for demonstrating multi-dimensional systems and assessment of fetal anomalies.
