Abstract:

针对微波消融技术应用中的无创监测组织温度难题,通过B超原始射频信号重建B超图像,排除B超仪器的相关性,探讨了利用B超图像纹理特征实现热疗温度监测的可行性.通过水浴加热猪肝实验,采集不同温度下的猪肝B超射频信号,在此基础上重建B超图像并分析图像纹理特征参数(灰度直方图、灰度共生矩阵与灰度梯度共生矩阵)与温度的相关性.实验结果表明:组织B超图像纹理参数随着温度变化而变化,在20~60℃范围内灰度直方图中的灰度均值,灰度共生矩阵中的熵以及灰度梯度共生矩阵中的混合熵、逆差距、相关等5个参数与组织温度间具有较高的线性相关性,利用这5个参数可实现肿瘤微波消融治疗中组织温度的无创检测.
