Congenital heart defect is the most common congenital anatomical malformation of the fetus

and it is also one of the malformations that are most easily missed in prenatal ultrasound examination.Ultrasound imaging technology is currently the most commonly used method of fetal heart examination in clinical practice and plays an important role in the diagnosis and screening of congenital heart disease.With the continuous development of computer science and technology and the advent of electronic matrix probe

three-dimensional ultrasound imaging technology is becoming a crucial technique in prenatal screening and diagnosis of congenital heart disease.In this paper

we summarize the recent advances in the application of electronic matrix probe related three-dimensional ultrasound imaging technology in fetal heart.
