Description

一种超声影像分析系统及其分析方法 技术领域
本发明涉及医用超声图像分析领域, 尤其涉及一种超声影像分析系 统及其分析方法。
背景技术
联合国世界卫生组织下属的国际癌症研究机构(IARC )报告 2008 年 确诊癌症 1270 万, 760 万人死于癌症, 2030 年全世界确诊癌症病人将 有大约 2140 万, 1320 万人将死于癌症。 当前中国肿瘤病发率和死亡率 都呈加速发展态势。 肿瘤介入治疗已作为临床最主要治疗手段之一, 超 声介入治疗又是其中发展最块, 对肝癌、 肺癌、 曱状腺癌有着明确治疗 效果的手段。 在中国, 肝癌是最常见的恶性肿瘤之一, 每年肝癌死亡达 30 万人, 肝癌死亡率占恶性肿瘤的第二位。 在治肝癌的诸多疗法中, 目 前仍首推手术切除。 8 0 %的肝癌患者因为肝硬化导致肝功能和凝血机 制差, 或者由于肿块部位及心肾功能差等制约因素, 不能做手术切除, 剩下的 2 0 %的肝癌患者即使接受手术切除, 复发率仍高达 7 0 %。 而 肝癌细胞通常对化疗和放疗不敏感。 因此各种非手术的介入性治疗, 成 为了临床治疗肝癌的重要手段。
在超声引导肿瘤消融治疗过程中, 超声造影被用来对介入治疗结果 进行评估。 目前主要的评估手段是釆用对术前、 术后的超声二维造影, 测量肿瘤区域的长径, 该测量不能保证两次测量时超声切面和位置的一 致性, 尤其在大肿瘤多针消融时, 简单的长径测量不能代表整个消融区 域。 目前的三维超声造影技术, 大都用来单独显示目标区域的单独状态, 或则釆用 4D 成像, 显示目标区域的动态血流灌注形式。 另外的介入效 果评估方案是基于 CT/MRI 设备进行断层成像, 但是该方案不能满足临 床手术治疗后即时评估的要求,而且同样缺少针对肿瘤介入治疗的术前、 术后的三维体积定量对比功能。 而且, 临床大都单独观察某一时相的三 维造影结果。 显然, 这样的观察结果准确率不高。
不难看出, 现有技术还存在一定缺陷。

作为优选, 所述超声影像分析系统还包括:
图像存储模块 104, 用于存储第一组三维超声图像数据、 第二组三 维超声图像数据和 /或所述图像分析模块 102所获得的配准映射关系。
作为优选, 所述图像显示模块 103包括:
图像重建子模块, 用于接收选择目标区域的选择信号, 并用第一组 三维超声图像数据和第二组三维超声图像数据中的一组三维超声图像数 据重建出目标区域的第一图像; 以及根据配准映射关系, 用第一组三维 超声图像数据和第二组三维超声图像数据中的另一组三维超声图像数据 重建出与该第一图像对应的该目标区域的第二图像。

作为优选, 所述图像显示模块 103还可以包括:
图像测量子模块, 用于对所述第一组三维超声图像数据、 第二组三 维超声图像数据和改进图像分析模块 102所生成的配准映射关系进行测 量和编辑。
图像自动配准算法主要包括两部分, 即图像间的相似性度量方法和 图像间的映射方法。根据映射方法不同,可以分为刚体变换 (旋转和平移, 即刚体配准)、 放射变换 (放缩、 旋转和平移, 即放射配准)和非线性变换 (对不同局部的图像建立不同的映射, 即非线性配准)。 结合超声三维造 影成像特点, 下面给出刚体配准和放射配准的两种实施方案, 需要说明 的是, 本实施例不限定于某一种配准算法。 如果两组造影数据是在同一 深度下釆集, 即釆集的像素是同一尺度, 配准算法可以限定为刚体配准, 即包括旋转和平移。 如果两次釆集时深度设定不一致, 即釆集到的图像 像素大小尺度不一致, 则釆用双线性差值算法把两组数据放缩到同一尺 度, 然后按照刚体配准进行配准计算。
假设某组三维超声造影图像数据中像素点为 的图像亮度为 f (X , 另一组三维超声造影图像数据像素点 ^ 的图像亮度为 g (¼) , 两组三维超声造影图像数据间映射可表示为: 同时可定义两
Figure imgf000009_0001
E二 /m - g
ί=ί…- Ν
上述相似性度量为典型的 "最小绝对差值和" , 类似的定义方式还 有: "最小平方误差和"和"最大互相 \..)关",以及基于超声波噪声 Rayleigh 分布特性改进的最小绝对差值算法。 同时度量函数中的 f (X 和 g (Y 还可以定义为对应数据的局部梯度大小、 局部灰度商等等形式。 具体的 自动配准算法在图像处理领域有很多文献资料, 在此只给出易于实现的 实施方案。
进行图像配准操作时, 除了可以釆用上述自动配准算法外还可以釆 用半自动配准 (即交互式配准) 实施方案, 即结合人机交互模块 105和 图像显示模块 103 , 进行交互式配准。 在假设刚体配准要求下, 映射矩 阵 A 的左上角 3 x 3 矩阵为对称正交矩阵。 求解两组三维超声数据间的 刚体配准方法有多种, 最直接方案是利用交互式操作, 分别在两组三维 超声数据上选择 4 组或者 4 组以上的对应点对,通过最小二乘拟合方法 求解最优映射矩阵 A; 也可以是在两组三维超声数据上分别选择一个切 面, 用融合显示的方式, 建立两个切面的——对应关系, 然后在两组数 据中选择一个对应点对, 该对应点对在已知的两个切面外。 上述两种交 互式配准方法是常见的两种方案, 在此只给出易于实现的实施方案。 需 要说明的是, 进行图像配准操作时还可以是交互式配准与自动配准算法 的组合应用。
配准操作完成后可以基于图像显示模块 103显示配准结果。 需要说 明的是, 如图 2 所示, 所述图像显示模块 103的屏幕区域至少包括两个 显示子窗口, 用于对比显示两组数据。 显示的配准结果可以是三维超声 组织图像数据、 三维超声造影图像数据或者是两者的组合。
图像显示模块 103同时包含图像多平面重建相关功能, 结合人机交 互模块 105功能, 在图像中选择一个目标区域, 并对目标进行多平面重 建。 重建出来的切面可以是三维超声组织图像也可以是三维超声造影图 像。 在所述显示子窗口中分别显示重建后的两组图像, 例如: 在其中一 个显示子窗口中显示从第一组三维超声造影图像数据中重建出来的图 像, 在另一个显示子窗口中显示与之对应的从第二组三维超声造影图像 数据中重建出来的图像, 这两个显示子窗口中显示的图像中的像素是一 一对应的。 需要说明的是, 所述两个显示子窗口中显示的可以是三维超 声组织图像数据也可以是三维超声造影图像数据, 也可以支持两种数据 间的切换。
需要说明的是, 所述图像显示模块 103所显示的第一组三维超声图 像数据和第二组三维超声图像数据包括但不限于: 第一组三维超声图像 数据和第二组三维超声图像数据的一部分、 一个切面、 多个切面和第一 组三维超声图像数据或第二组三维超声图像数据在某个方向的投影。
与此同时, 作为优选, 所述两个显示子窗口还可以支持测量功能, 例如距离测量、 面积测量、 勾边、 描迹等; 两个显示子窗口还可以支持 测量功能联动显示, 即在其中一个显示子窗口进行测量操作, 在另外一 个显示子窗口的相同位置显示同样操作; 同时也可以支持解除联动操作 功能, 单独对某一个显示子窗口进行测量操作。 上述显示子窗口可以显 示一个图像切面, 也可以同时显示多个切面, 即两个显示子窗口中按照 相同顺序排列的图像。 所述图像显示模块 103的屏幕区域以支持使用者 选择不同的切面 (重建后的) 进行显示和测量操作。
本实施例还优选提供如下几种超声影像分析方法, 下面将对这几种 超声影像分析方法做进一步阐述。
第一种:
如图 3 所示, 一种超声影像分析方法, 包括:
釆集第一组三维超声图像数据和第二组三维超声图像数据。 在上述 的图像釆集模块 101中釆集第一组三维超声图像数据和第二组三维超声 图像数据, 具体的釆集方法可以与上文所述的三维超声图像数据获取环 节一致, 在此不再赘述。
对所釆集的第一组三维超声图像数据和第二组三维超声图像数据进 行分析配准, 获得第一组三维超声图像数据和第二组三维超声图像数据 之间的配准映射关系。 具体的三维超声图像数据分析配准方法可以釆用 上述的自动配准方法或者是半自动配准方法, 也可以同时釆用自动配准 方法和半自动配准方法的组合应用对所釆集的两组三维超声图像数据进 行分析配准, 具体的如何配准, 在此不再赘述。
根据配准映射关系在上述的图像显示模块 103中显示第一组三维超 声图像数据和第二组三维超声图像数据。
本实施例中, 根据配准映射关系显示第一组三维超声图像数据和第 二组三维超声图像数据可以包括下列步骤:
首先, 接收选择目标区域的选择信号。 该选择信号可以是由用户通 过人机交互模块 105输入的, 也可以是系统默认的。 通过该选择信号可 以确定用户感兴趣的目标区域。 该目标区域可以是第一组三维超声图像 数据或者第二组三维超声图像数据中的一部分。 也就是说, 目标区域可 以在第一组三维超声图像数据中选择, 也可以在第二组三维超声图像数 据中选择。
然后, 用第一组三维超声图像数据和所述第二组三维超声图像数据 中的其中一组三维超声图像数据重建出该目标区域的第一图像, 并在显 示器的第一区域中显示该第一图像。
然后, 根据前述的配准映射关系, 用第一组三维超声图像数据和所 述第二组三维超声图像数据中的另一组三维超声图像数据重建出与该第 一图像对应的目标区域的第二图像。 容易理解, 由前文所述, 已经获得 了两组三维超声图像数据的配准映射关系, 则, 在其中一组三维超声图 像数据中选择了目标区域后, 根据该配准映射关系, 即可获得该目标区 域在另一组三维超声图像数据中的对应区域, 用另一组三维超声图像数 据重建出的该对应区域的图像, 即为前文所说的与第一图像对应的目标 区域的第二图像。

本实施例中, 根据配准映射关系显示第一组三维超声图像数据和第 二组三维超声图像数据的方法步骤可以与前述第二种方法中的相同。

在其中一组三维超声图像数据中选择目标区域, 按照选定方向重建 出所述目标区域的切面, 并显示该组三维超声图像数据的切面; 基于两 组图像的配准映射关系, 在另一组三维超声图像数据中重建出与之前重 建出的一组三维超声图像数据切面对应的切面, 并显示该切面。
运用所述图像重建子模块, 重建目标区域在两次釆集时候获得的图 像数据, 在三维超声图像数据中选择一个目标区域, 并对目标进行多平 面重建, 重建后的图像数据是——对应的。 重建出来的切面可以是三维 超声组织图像数据也可以是三维超声造影图像数据。 例如: 在其中一个 显示子窗口中显示从第一组三维超声图像数据中重建出来的图像, 在另 一个显示子窗口中显示与之对应的第二组三维超声图像数据中重建出来 的图像, 这两个窗口中显示的图像中的像素是——对应的。
