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

[0048] 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.

[0049] 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.

[0050] 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 doctor...

Abstract

The embodiment of the present application provides a method and apparatus for detecting bone age. The method comprises: obtaining a bone age piece of a user to be detected, and adjusting the bones inthe bone age tablet to the reference position, determining a thumb bone region from that bone age slice, then identifying the medial thumb sesamoid in the thumb bone region by using the recognition model, which is determed by taking the bone age slices of the thumb bone region pre-marked with the medial thumb sesamoid as the training samples, and training the depth residual network after, finally,determining the bone age of the user to be detected according to the recognition results of the medial thumb sesamoid. Since the appearance of the medial thumb sesamoid represents a specific bone agestage, the recognition model is used to identify the medial thumb sesamoid bone, and the bone age of the user to be detected is determined according to the recognition result of the medial thumb sesamoid bone, so that the artificial subjective judgment of the bone age according to the bone age sheet is not required, thereby improving the precision of detecting the bone age on the one hand, and the efficiency of detecting the bone age on the other hand.

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...
