Automatic quality control system and detection method of fetal ultrasonic section image

Abstract

The invention provides an automatic quality control system for a fetal ultrasonic section image. The automatic quality control system comprises a fetal ultrasonic section data acquisition module, a fetal ultrasonic section data preprocessing module, a fetal ultrasonic section data evaluation module and a fetal ultrasonic section data feedback module. The fetal ultrasonic section data preprocessingmodule receives original fetal ultrasonic section data acquired by the fetal ultrasonic section data acquisition module, preprocesses the original fetal ultrasonic section data and transmits the preprocessed original fetal ultrasonic section data to the fetal ultrasonic section data evaluation module. The evaluation module outputs the preprocessed fetal ultrasonic section data through a deep learning segmentation network to obtain standard fetal ultrasonic section image information and non-standard fetal ultrasonic section image information. The feedback module feeds back a fetal ultrasonic section image generation score and a quality evaluation report according to an evaluation result of the evaluation module. Meanwhile, the invention further provides a quality control method adopting the fetal ultrasonic section image quality control system.

Description

technical field [0001] The invention relates to the technical field of prenatal ultrasonic examination, in particular to an automatic quality control system and detection method for fetal ultrasonic section images. Background technique [0002] At present, fetal ultrasonography is the preferred examination method for prenatal diagnosis and defect screening. However, due to the uncertainty of fetal position, maternal body mass index, doctor's operation techniques, ultrasound physical characteristics, fetal movement and other factors, there are often great differences in the clarity and standardization of fetal ultrasound images obtained by ultrasound examination. Greatly affected the accuracy of the test results. Therefore, it is necessary to carry out quality control (Quality Control, QC for short) on fetal ultrasound section images. [0003] The existing method for quality control of fetal ultrasonic slice images is mainly through the subjective evaluation and objective s...
