AI Technical Summary

Technical Problem

In magnetic resonance (MR) imaging, imaging rates often fail to track the rapid position or temperature changes of the target during focus ultrasound treatment, resulting in inefficiency in treatment or safety risks.

Method used

By utilizing machine learning algorithms, such as neural networks, the lost k-space data is estimated by calculating the method and images are generated based on iteratively updated estimation information to accelerate MR temperature measurement.

Benefits of technology

Real-time monitoring of the temperature and location of the target area during ultrasound treatment is achieved, the MR imaging rate and resolution are improved, and inefficiency and safety risks during the treatment process are reduced.
