According to the State Administration for Market Regulation, China has established scoring standards for ultrasound sections and quantitative scoring models for key anatomical structures. It has led the development of six industry and group standards and initially established an intelligent quality control standard system for fetal ultrasound, effectively filling the gap in standardization construction in this field. During the 14th Five Year Plan period, the State Administration for Market Regulation organized domestic advantageous scientific research forces to conduct systematic research on fetal ultrasound standard reference maps and intelligent evaluation technologies, achieving a series of innovative results and promoting major breakthroughs in the field of intelligent quality control of fetal ultrasound in China. The research team broke through the limitations of traditional static maps and proposed and established a dynamic evolution mechanism for fetal ultrasound standard reference maps. For the first time, they proposed and implemented the acquisition of standard dynamic short videos, forming a dynamic standard reference map for gestational age evolution and individual differences, which was officially published by Science Press; We have established the world's first large-scale fetal ultrasound database with full cycle coverage and multi center distribution.
