The CIRS Model 068 Fetal Ultrasound Biometrics Phantom facilitates teaching and demonstration of fetal ultrasound techniques in a non-stressful situation.A tissue equivalent full fetal model is suspended in a nonechoic, amniotic fluid-like environment. The model is housed in a rotatable cylinder with 2 fields of view. A variety of fetal/transducer orientations can be achieved. 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. All anatomies are based on published biometric data for normal fetal growth rates for a gestational age of 21 weeks. This enables assessment of composite measurement techniques and biometric analysis programs common to most ultrasound scanners.
