Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work all belong to the protection scope of the present invention.

[0022] Such as figure 1 As shown, the bone age evaluation method of the embodiment of the present invention comprises the following steps:

[0023] S1, input the bone age film image, and locate the positions of multiple bones / physis in the bone age film image, so as to obtain partial images of multiple bones / physis.

[0024] The bone age film image in the embodiment of the present invention is an anteroposterior X-ray film of the wrist. In one embodime...

Abstract

The invention provides a bone age evaluation method and device, and the method comprises the following steps: inputting a bone age film image, and determining the positions of a plurality of bones / epiphysis in the bone age film image, so as to obtain a plurality of bone / epiphysis local images; taking the local images as nodes, constructing a growth mode topological graph for describing bone / epiphysis development characteristic relevance, and fusing the characteristics of the target bone / epiphysis and the associated bone / epiphysis through a graph convolution network so as to determine whether the bone / epiphysis at each position develops abnormally or not; if the bone / epiphysis at at least one position develops abnormally, correcting the abnormally developed bone / epiphysis; and calculating the bone age according to the correction result. According to the invention, the influence of abnormally developed bone or epiphysis on bone age evaluation can be corrected, so that the accuracy of bone age evaluation is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a bone age evaluation method and a bone age evaluation device. Background technique [0002] Bone age is the main method to evaluate the biological age of adolescents and children, and it is widely used in the fields of clinical medicine, forensic science and sports medicine. Bone age films are usually taken with anteroposterior radiographs of the non-handed. The development process of each bone and epiphysis in the wrist follows certain genetic characteristics and order. In clinical application, abnormal bone or epiphysis can be seen, such as the common "physiological variation of the fifth middle phalanx: short phalanx" in the Chinese population, which accounts for about 2%-6% of the population in various regions of China. X-ray imaging showed early development and fusion of the fifth middle phalanx. [0003] Generally, the abnormal development of bones and epiphyse...
