Abstract

The invention relates to the technical field of medical ultrasonic detection, and discloses a medical ultrasonic detection probe posture adjusting method and system. Through an attitude sensor integrating an inertial measurement unit and an optical sensor, high-precision fusion attitude information is generated by using a sensor fusion algorithm. The system calculates attitude deviation based on a preset target attitude model, and drives the adjusting mechanism to automatically correct the probe attitude through a proportional-integral-derivative control algorithm. And a dynamic weighting function and an ultrasonic image feedback mechanism are introduced, so that accurate control of deviation quantification and adaptive attitude calibration are realized. The problems that a traditional method depends on manual adjustment and is low in precision are solved, the ultrasonic image quality and diagnosis efficiency are remarkably improved, and the biomedical engineering industry is promoted to develop towards the intelligent and precise direction.
