Abstract：we proposed an automatic alignment system of the reference standard planes of fetal face from three-dimensional (3D) ultrasound image.First,the median sagittal plane (MSP)was localized based on the automatic detection of two eyeballs.Then,the facial coronary plane (FCP)was localized based on the automatic detection of facial profile line in the MSP.At last,the nasal bone, the eyeballs and the facial profile line were combined to localize the axial plane (AP)and define the fetal facial base vectors in 3D ul-trasound.Experimental results on 80 3D ultrasound images showed that the degree errors of the MSP,FCP and AP planes by our auto-matic system were 3.836 ±2.954,4.870 ±3.822 and 4.805 ±4.005,respectively.The distance errors (mm)of the MSP,FCP and AP planes by our automatic system were 2.022 ±1.707,2.921 ±1.887 and 2.543 ±1.578,respectively.The results demonstrate the feasibility,repeatability and reliability of the developed system.
