Method and system for quality control of fetal ultrasound images

Abstract

The invention provides a fetal ultrasound image quality control method and system. Through inputting a fetal abdominal scan section gray image obtained by a clinical ultrasound doctor, a local phase characteristic is extracted to obtain corresponding local symmetric phase and asymmetric phase images, an RGB image is formed by combining the local symmetric phase and asymmetric phase images and the gray image, the positioning to an ROI is achieved by using L-CNN model, whether the ROI in a section is in accordance with a first index is judged, then a C-CNN model analyzes an identified ROI, whether SB is in accordance with a second index and whether UV is in accordance with a third standard are judged, and thus the fetal ultrasound image quality control is realized. The invention provides the fetal ultrasound image quality control method and system, through the quantitative quality control of fetal abdominal scan section automatic evaluation, and the purpose of objectively evaluating section quality can be realized, which is more economical and effective than manual operation of an expert.

Description

technical field [0001] The invention relates to the technical field of medical images, in particular to a method and system for controlling the quality of fetal ultrasound images. Background technique [0002] Ultrasound is widely used in prenatal examination due to its advantages of real-time acquisition, low cost, no radiation, and portability. Usually, the process of prenatal ultrasound examination includes: ultrasound probe scanning, standard section acquisition, biometric measurement, and gestational age weight determination. Biometric measurement is necessary for the determination of gestational age and weight, and biometric measurement is required to be carried out on the standard section, which shows that only the measurement value of the standard section can accurately estimate the gestational age and body weight, which shows the importance of the standard section sex. [0003] But not all physicians can obtain standard cut planes. like figure 1 (a) is the cut s...

Problems solved by technology

Generally, experienced physicians (experts) score the ultrasound scan sections according to the agreement to achieve the purpose of quality control, but the quality control of manual scoring by experts has many disadvantages: ①It is more inclined to the subjectivity of experts; ②It relies heavily on the experience of experts ③Repetitive operations are time-consuming and labor-intensive, which is impossible in clinical practice
