Ultrasonic bone age detection system and method

Abstract

The invention discloses an ultrasonic bone age detection system and method. The method includes the steps of 1, soaking to-be-detected tissue in a coupling medium, partially dipping a scanning windowinto the coupling medium to contact with the to-be-detected tissue, setting a contact pressure threshold and fixing the scanning window; 2, adjusting an ultrasonic probe in position and angle according to an ultrasonic image of the hand to allow the long axis of the ultrasonic probe to be perpendicular to the tangent plane of the to-be-tested tissue during scanning; 3, setting a scanning parameterand performing scanning to acquire an ultrasonic bone age image of the to-be-detected tissue. The image of a bone age feature area is acquired through the ultrasonic bone age detection system to assess the bone age of children, imaging quality is guaranteed after completion with one-time scanning, wide-field of view is achieved, and the problem about operator dependency is solved; a children's skeletal system has more cartilage compositions and ultrasonic imaging is superior to adults in terms of acoustic transmission, so that the ultrasonic bone age detection system and method is applicableto bone age detection in children.

Description

technical field [0001] The invention relates to the technical field of ultrasonic detection, in particular to an ultrasonic bone age detection system and a method thereof. Background technique [0002] At present, the bone age evaluation methods widely used at home and abroad are mainly Greulich-Pyle (G-P) atlas method and Tanner-Whitehouse (TW2) scoring method. In the 1990s, domestic scholars made appropriate revisions to the TW2 method based on the wrist data of teenagers aged 0-19 in my country, and formulated the Chinese bone maturity evaluation standard, namely the CHN method. All of the above methods require X-ray filming, which poses radiation hazards to children in the development and growth period, and repeated testing is not suitable, which limits the time limit for its clinical application. [0003] In principle, all parts of the human skeleton can be used to estimate the degree of maturity, but because of the large number of bones in the wrist, there are 29 bone...

AI Technical Summary

Problems solved by technology

However, due to the short time for ultrasound to evaluate bone age, it is still in the stage of exploration and accumulation of experience; in addition, there are differences in the operation techniques of sonographers and the setting of acquisition system parameters, so there is still no unified and recognized standard for ultrasound evaluation of bone age. Some technical methods also require special equipment, which limits the application of this technology in bone age determination.
