Article Synopsis
- Radiofrequency ablation (RFA) is a treatment for liver tumors that requires temperature monitoring to ensure effective thermal dosage, primarily using ultrasound temperature imaging that detects echo time shifts.
- Traditional methods use a fixed coefficient (k) to relate temperature changes to echo shifts, which can lead to errors when temperatures exceed 50°C.
- This study introduces an adaptive-k algorithm that dynamically adjusts this coefficient during monitoring, tested on porcine liver samples, and found to significantly improve the accuracy of temperature estimation, particularly at higher temperatures.
