Description

[0002] Children belong to a vulnerable group in human society. They are relatively weak and easily attacked by diseases. Ultrasound examination can more intuitively obtain the causes of children's diseases.

[0003] During ultrasound examinations of the heart, hip joints and other aspects of children, it is difficult for children to fix their positions and cooperate poorly during the examination due to their easy movement and poor comfort. When operated with bare hands, the image is difficult to stabilize and easily deviates, resulting in poor repeatability of ultrasound measurements and large errors. The examination is terminated due to the crying of the child.
