Bone age evaluation method and device, electronic equipment and computer readable storage medium

Abstract

The embodiment of the invention provides a bone age evaluation method and device, and solves the problems that an existing bone age evaluation method cannot automatically identify difficult bone/epiphysis and cannot effectively intervene in uncertainty of bone age evaluation. The bone age evaluation method comprises the following steps: inputting a bone X-ray image into a bone age evaluation network model to obtain probability distribution data, the probability distribution data comprising a plurality of matching probability values corresponding to a plurality of standard bone age maps, and the plurality of standard bone age maps corresponding to a plurality of bone age standard values; inputting the bone X-ray image into an uncertainty estimation network model to obtain an uncertainty prediction value used for representing the uncertainty of the bone age evaluation value of the bone X-ray image; and when the uncertainty prediction value is greater than a preset threshold, sending keyauditing prompt information. According to the invention, bone/epiphysis with high uncertainty (easy to diverge) can be evaluated according to automatic identification of bone age, and doctors are recommended to focus on auditing.

Description

technical field [0001] The present application relates to the technical field of image analysis, and in particular, to a method, device, electronic device and computer-readable storage medium for evaluating bone age. Background technique [0002] Bone age is the main method to evaluate the biological age of adolescents and children, and it has preventive uses in the fields of clinical medicine, forensic medicine and sports medicine. At present, the widely used bone age assessment methods at home and abroad mainly include the atlas method and the scoring method. However, the results of bone age evaluation are affected by "uncertainty" factors such as differences in doctors' cognition, discontinuity of standard bone age maps, and changes in X-ray shooting angles, and there are great uncertainties. In clinical application, differences often occur between different expert readers. As mentioned in the monograph "Zhonghua-05", the random error (±0.35 years old) between 13 bone a...
