Description

A bone age detection system

The present invention is proposed by the applicant, the application date is November 12, 2021, the application number is CN202122781215.X, and the priority of the application titled "a bone age detection system" is claimed. The entire content of the above application is hereby incorporated by reference in its entirety.

technical field

The invention relates to a medical device, in particular to a bone age detection system.

Background of the invention

Skeletal age, referred to as bone age, is determined by the degree of bone calcification. In the process of human growth and development, the skeletal system is the easiest to truly reflect the growth time, which can more accurately reflect the various ages in the process from birth to full maturity. Bone age plays an important role in the analysis and diagnosis of developmental diseases, endocrine diseases, developmental disorders, nutritional disorders, genetic diseases and metabolic diseases.

At present, the traditional bone age detection method is: the patient orders a checklist from the doctor, and then goes to the radiology department to take a film through the DR machine; after the film is completed, the doctor manually evaluates the registration of 20 key points, and calculates the bone age according to the grade score; and then According to the patient's bone age, height, weight and other data, the target height, percentile and other content are calculated for further calculation, and finally a report is given, and the doctor makes a diagnosis through the report. The patient's diagnosis process is cumbersome, time-consuming and laborious.

There are two types of equipment used to detect bone age on the market: 1. DR equipment. DR equipment needs to be photographed in the radiology department. The radiation dose is relatively high during the photographing, and the patient's whole body will be exposed to X-rays.
