Problems solved by technology

[0005] Due to the fact that the prior art relies on manual estimation of bone age based on bone age films, the accuracy is subject to human subjective factors, the image is large, and the efficiency is low. The embodiment of the present application provides a method and device for detecting bone age

Embodiment Construction

[0053] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054]Bone age: Abbreviation for skeletal age, which needs to be determined with the help of specific images of bones in X-ray imaging. Usually an X-ray of the left wrist is taken, and the doctor observes the development degree of the ossification center of the metacarpophalangine, carpal bone and the lower end of the radius and ulna of the left hand through the X-ray to determine the bone age.

[0055] The technical solution for bone age detection in the embodiment of the present application is suitable for hospitals to detect the bone age of adolescents, providing reference for doctors...

Abstract

Embodiments of the present application provides a method and apparatus for detecting bone age, and relates to the technical field of machine learning. The method comprises the following steps: acquiring a bone age slice of a user to be detected, adjusting each bone in the bone age slice to a reference position, determining a wrist bone region from the bone age slice, then determining the number ofossification centers in the wrist bone region by using a classification model, and finally determining the bone age of the user to be detected according to the number of ossification centers in the wrist bone region. Because the number of ossification centers in the carpal region represents different bone age stages, as such, embodiments of the present application employ classification models toautomatically determine the numb of ossification centers in the carpal region, then, the bone age of the user to be detected is determined according to the number of ossification centers in the wristbone region, without artificial subjective judgment of bone age according to bone age slices, so that on the one hand, the precision of detecting bone age is improved, and on the other hand, the efficiency of detecting bone age is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of machine learning, and in particular to a method and device for detecting bone age. Background technique [0002] "Bone age" is the abbreviation of skeletal age. It is the developmental age obtained by comparing the skeletal development level of adolescents and children with the bone development standard. It can more accurately reflect the maturity of the body than age, height, and weight, and more accurately reflect the individual. level of growth and maturity. [0003] Clinically, the biological age of children can be judged by detecting bone age, the development status of children can be evaluated by the difference between biological age and calendar age, the trend of sexual maturity of children can be understood, the adult height of children can be predicted, etc., and it is widely used in diseases that affect children's growth and development Treatment monitoring is of great...
