摘要
摘要:高强度聚焦超声(HIFU)是一种无创、低费用的新型肿瘤治疗手段。但是目前仍无一种有效的HIFU无损温度监控及检测治疗方法可应用于临床。该文采用数据挖掘中的回归分析模型,挖掘HIFU焦域处超声剪影图像中可用于温度估计的信息。结果表明在70℃以下的温度范围,采用该回归方程进行温度估计的精度为3℃。
High Intensity Focused Ultrasound is a type of non-invasive low-cost method for tumor treatment There is still no non-inva- sive temperature monitor system for HIFU could be used in clinic. We used the regression model of data mining to discover temperature related information hidden in the HIFU focal area subtraction ultrasound images. Result shows that the temperature estimate precision is 3℃, at temperature under 70℃ , by using the regression formula.
