Measurement system and method of acetabular bone coverage degree based on ultrasonic image

Abstract

The invention discloses a measurement system of an acetabular bone coverage degree based on an ultrasonic image. The measurement system comprises a pre-processing module, an edge detection module, an analysis processing module and a coverage degree measurement module. A measurement method comprises the following steps: S1, carrying out detail enhancement processing; S2, carrying out outline completion processing; S3, carrying out image analysis processing; and S4, measuring a coverage ratio. According to the measurement system and the measurement method, the obtained ultrasonic image is subjected to the detail enhancement processing and the outline completion processing; then an iliac bone A, a round outermost side edge point B of a femoral head, an outermost edge point C of an inner side of an acetabular bone, a base line D, a femoral head reference line and an acetabular bone reference line are determined; and finally, the acetabular bone coverage ratio R is calculated by utilizing a vertical distance L1 between the round outermost side edge point B of the femoral head and the base line D, and a vertical distance L2 between the outermost edge point C of the inner side of the acetabular bone and the base line D. The measurement system and the measurement method have relatively low requirements on the skill level of an operation way and the definition of the image, so that the measurement speed is relatively high and errors are not easy to occur.

Description

technical field [0001] The invention specifically relates to a measurement system and method for measuring the degree of acetabular coverage based on ultrasonic images. Background technique [0002] The hip joint supports the torso and connects the lower limbs. It is the most needed and most critical part in walking, sitting and lying. The hip of the hip joint is an important hub connecting the human trunk and lower limbs. The hip of the hip joint covers part of the thigh The end of the bone, in order to ensure the flexibility and stability of the joint, often needs to measure and analyze the degree of coverage of the baby's acetabulum in medical research. [0003] The existing measurement methods are mainly through X-ray and ultrasound images. However, most of the hip joints of infants and young children are composed of cartilage components, and the femoral head has not yet been ossified. It is difficult for X-rays to show the structural shape of the hip joints, and there i...
