At present, there are mainly two methods of scanning detection for internal information o...

AI Technical Summary

Problems solved by technology

The detection area of ​​manual detection is flexible and changeable, but because the exact position of the ultrasound probe is not known, it will cause a lot of trouble in the image stitching of the post-detection processing, which makes the post-detection processing algorithm complex and the imaging accuracy is not high

Automatic detection is easy to deal with the image stitching problem of post-detection processing because of knowing the position information of the ultrasound probe, but this kind of detection generally has a fixed detection area
