Embodiment 1

[0124] Model establishment: From January 2013 to January 2016, 3500 first-trimester ultrasound images stored in the Obstetrics and Gynecology Ultrasound Workstation of Sun Yat-sen Memorial Hospital of Sun Yat-sen University were collected. Eligible images were screened out, and the image criteria for inclusion in the study: the fetal head was fully displayed, and the head and thorax accounted for 70% to 85% of the entire graphics area; 130°~160°; the nose tip area of ​​the head should be the largest highlighted area in the whole image.

[0125]After manual screening of 1,500 images that meet the measurement conditions, obtain the pixel distance and actual distance conversion parameters of the ultrasound image, and mark the head area and NT area; ①Get the average offset value of the head area and NT area; ②Use the Adaboost algorithm And use HOG feature training to obtain head region detector; ③Adaboost algorithm and use HOG feature training to obtain NT region detector.

Abstract

The invention discloses a method and system for detecting the position of the transparent object on the nape of the fetus combined with medical statistical information. shift value; input the ultrasonic image, obtain the pixel distance and actual distance conversion parameters of the ultrasonic image; determine the head area; determine the NT area, which is the fetal neck, by the determined head area and the average offset value between the head area and the NT area The location of the back transparency. The present invention first determines the position of the head region, determines the NT region through the average offset value between the head region and the NT region, and combines the standard or prior knowledge of the NT ultrasonic image to improve the overall accuracy and stability of the detection method.

Description

technical field [0001] The invention belongs to the field of image processing and image recognition, and relates to a detection technology for a specific target in an ultrasonic image, in particular to a method and system for detecting the position of a transparent object on the nape of a fetus combined with medical statistical information. Background technique [0002] Birth defects such as congenital deformities, mental retardation, and metabolic diseases are the main causes of perinatal and infant deaths. At present, there are about 800,000 to 1.2 million babies with birth defects in my country every year, accounting for about 4 to 6% of the total number of births in the year. Seriously affect the quality of our country's population, but also caused a huge burden on society and families. In view of the fact that there is no cure for such diseases in medicine at present, prenatal screening is the only effective means to reduce the birth rate of defective children. Therefor...
