Description

一种基于人工智能的射频消融参数优化和信息合成方法及 系统
技术领域
本发明涉及射频消融技术领域,具体地说,涉及一种基于人工智能的射频消融参数优化和信息合成方法及系统。
背景技术
目前,现有的射频消融设备主要聚焦于电压和功率的产生,以成功地将高频电能传输到病人的目标组织;而且主要依靠主治医生的临床经验进行操作,相应的控制参数尚缺少精确的热学依据。由于消融的过程涉及到生物学、传热学、力学、临床医学等诸多学科领域,因此需要精确控制消融范围,尽可能减少不必要的损伤,保证在不伤及正常组织细胞的情况下最大限度地摧毁病灶细胞。
在手术过程中一般利用电流和温度的阈值来估计和控制能量传输,保护病人的安全和保障医疗器械的使用。但是测量动态电流和温度不能实现实时控制,并且效率不高。而且目前的消融设备不能做到自动闭环的消融或凝血的攻率和能量配置。
此外,鉴于微创操作技术具有较高的技术门槛和较长的学习曲线,年轻的医师难以具备足够的知识和经验,对年轻医师的培训和工作初期的指导尤其困难,现有的培训方法通常依赖于知识点讲解、视频介绍等,医师的长期操作经验无法精确表达,不能很好地帮助初学者了解操作步骤、辨识操作环境;对于射频参数的控制,需要考虑到决策输出针对人体治疗中的不同组织类型,如软组织、脂肪、骨头等;根据对模型及环境的单一分析不足以应付复杂的实际情况。因此,临床中亟待一种信息合成的方法和系统,可以在临床实操和模拟培训中,进行辅助的环境分析,并且提供匹配的操作参数,供医师参考。
发明内容

S2-2、对V进行归一化,并对每行求和,将求和后的数据组合成传感器系数矩阵W,对W进行归一化;
S2-3、对于样本数据所在的综合环境,分别针对单一环境根据柯西分布构建对应的关系矩阵R,所述的关系矩阵为k个;
S2-4、对传感器系数矩阵W和k个单一环境的关系矩阵R分别进行融合,即F=WR,得到k个单一采集环境的融合结果,[F1,F2,…,Fk];
S2-5、按照步骤S2-1至S2-4将多组样本的k个单一组织环境的融合结果[F1,F2,…,Fk],以及各样本对应的射频消融控制参数输入人工神经网络,设置网络的层数进行自学习,得到与样本数据对应的单一组织环境系数,建立的人工神经网络模型。
进一步地,所述的步骤S2中,模糊计算具体包括:
S2-1、构建传感器信号数据集S=[s1,s2,…,sn],n为传感器的数量;
基于传感器的种类和性质构建控制器的决策集D=[d1,d2,…,dm],m为决策结果数量,所述的决策集的元素为控制参数,包括消融电压电平,消融功率,脉冲时间,脉冲幅度和脉冲频率;
根据信号数据集S中的元素对决策集D输出的影响构建决策矩阵V,如表1所示:
