AI Technical Summary

Technical Problem

In mandibular border injections, existing ultrasound localization techniques struggle to accurately distinguish the platysma muscle from easily confused connective tissue, leading to a high risk of ineffective treatment or complications.

Method used

An image acquisition module was used to acquire ultrasound image sequences of the mandibular border. A region extraction module was used to determine the candidate muscle region. Threshold segmentation algorithm and morphological feature analysis were used to calculate the fat coefficient and contraction coefficient to accurately distinguish the platysma muscle from the connective tissue.

Benefits of technology

It improves the accuracy of layered and zoned ultrasound localization, reduces the risk of misjudgment, and provides real-time image semantic information assistance during the mandibular border injection process, ensuring injection safety.

Abstract

This invention relates to the field of ultrasound positioning technology, specifically to a layered and zoned ultrasound positioning system for mandibular border injection. The system includes: acquiring a sequence of mandibular border ultrasound images of the patient; determining a muscle candidate region based on the mandibular boundary morphology and grayscale changes in the mandibular border ultrasound images; determining the first echo region within the muscle candidate region using a threshold segmentation algorithm; obtaining a fat coefficient by combining the local morphological features and grayscale distribution of this region; acquiring the contour features, grayscale distribution, and fat coefficient of the first echo region in all mandibular border ultrasound images during mandibular resistance movements; obtaining the contraction coefficient of the first echo region; and using the contraction coefficient to assist in the assessment of the position during mandibular border injection. This invention improves the accuracy of layered and zoned ultrasound positioning during mandibular border injection.
