Hip joint standard ultrasonic image acquisition method based on Graf ultrasonic technology and intelligent system

Abstract

The invention discloses a hip joint standard ultrasonic image acquisition method based on a Graf ultrasonic technology and an intelligent system, and relates to an intelligent medical equipment system, in particular to an early screening technology for infant developmental dysplasia of joints. The method comprises the following steps: 1) establishing a picture substrate with a baseline; 2) presetting an identification area and an identification condition on the picture substrate; 3) acquiring an online ultrasonic image, and comparing and judging the online ultrasonic image with the preset identification area and the preset identification condition on the picture substrate; and 4) generating a standard image which can be used for measurement by using the online ultrasonic image which falls into the preset identification area and meets the preset identification condition. In the step 1), the ratio of the width to the height of the picture substrate is 1: (1-1.3), and a base line is arranged in the range of 10-20% of the width size of the two sides of the central point in the longitudinal direction of the picture substrate. According to the method, errors in screening can be effectively avoided, and the screening accuracy and efficiency are greatly improved.

Description

technical field [0001] The invention relates to an intelligent medical equipment system, in particular to an early screening technology for infant developmental dysplasia of the hip. Background technique [0002] Infant developmental dysplasia of hip (DDH) is birth-related and refers to abnormalities in the structure of the hip joint at birth and progressive deterioration during development, including hip joint instability to hip dislocation series of lesions. DDH ranks fifth among birth defects and is one of the most common musculoskeletal disorders that seriously endanger the health of infants. The etiology of DDH is unknown, but it may be related to genetics, amniotic fluid, fetal position, and birth conditions. Epidemiological studies have shown that about 12% to 33% of children with DDH have a positive family history, and the incidence of mechanical factors such as breech delivery is 16%; the incidence rate of girls is much higher than that of boys, and the risk facto...

Problems solved by technology

In addition, as an academic research, there are differences between the Graf method and other DDH diagnostic methods. The main point of controversy is that the Graf method does not have a corresponding relationship with the physical structure of the hip joint, so the measurement results cannot be used to explain the three-dimensional structure of the hip joint.

[0011] (2) The equipment standard of the Graf method is not perfect, and the screening technical means and methods are not easy to master

The lack of effective equipment has brought great troubles to doctors

[0012] (3) Carrying out a comprehensive Graf method for hip joint ultrasound screening is a heavy workload, and it is necessary to solve the problem of human resources

According to statistics in 2020, the number of babies born nationwide is about 10.035 million. After the implementation of comprehensive Graf hip ultrasound screening, the number of hip ultrasound examinations required is 1.25 times that of the birth population (including the number of normal screening and abnormal results. The number of interventions), the workload is huge

It still requires experienced medical personnel to manually operate and obtain a large number of images, and provide them to the system for screening, analysis, and measurement

If there is no "standard ultrasound image" that meets the subsequent analysis in a large number of images, the results cannot be obtained
