AI Technical Summary

Problems solved by technology

[0006] In clinical practice, doctors often need to monitor the thermal ablation area of ​​tumor cells and its surrounding environment. However, the amount of data collected by ultrasonic parametric imaging is relatively large. The transmission bandwidth and processing speed have high requirements, and it is difficult to apply it to a real-time system. If the traditional B-mode ultrasound imaging method is used for all areas, the monitoring quality of the tumor cell thermal ablation area cannot be guaranteed.
[0007] Moreover, the current ultrasonic parametric imaging technology only quantitatively calculates the changes in each position of the thermally damaged area at each moment, and cannot quantitatively and intuitively show the differences in different positions of the thermally damaged area at the same time, or the differences in the same position of the thermally damaged area at different times

Description

technical field [0001] The invention belongs to the technical field of ultrasonic monitoring imaging, and in particular relates to a multi-parameter monitoring method and system for ultrasonic thermal ablation based on demodulation domain parameter imaging. Background technique [0002] Tumor thermal ablation therapy refers to a treatment method that kills tumor cells by increasing tissue temperature under the guidance of imaging technology. It has the advantages of minimally invasive, safe, high operability, good repeatability, and fast postoperative recovery. During the ablation process, the accuracy of the positioning of the ablation probe and the judgment of the size of the ablation area are closely related to the quality of the monitoring image. Ultrasound imaging is widely used in dynamic monitoring of clinical thermal ablation process due to its real-time and non-destructive advantages. [0003] In clinical practice, doctors usually use ultrasonic B-mode imaging to m...
