请参阅图2,图2是本申请实施例提供了一种基于VRDS 4D医学影像的动脉与静脉Ai处理方法的流程示意图,应用于如图1所述的医学成像装置;如图所示,本基于VRDS 4D医学影像的动脉与静脉Ai处理方法包括:
S201,医学成像装置根据目标用户的目标部位的多张扫描图像确定位图BMP数据源;
其中,所述目标部分例如可以是肾脏。所述扫描图像包括以下任意一种:CT图像、MRI图像、DTI图像、PET-CT图像。
在一个可能的示例中,所述医学成像装置根据目标用户的目标器官关联的多张扫描图像确定位图BMP数据源,包括:所述医学成像装置获取通过医疗设备采集的反映目标用户的人体内部结构特征的多张扫描图像;从所述多张扫描图像中筛选出包含所述目标部位的至少一张扫描图像,将所述至少一张扫描图像作为目标用户的医学数字成像和通信DICOM 数据;解析所述DICOM数据生成目标用户的图源,所述图源包括纹理Texture 2D/3D图像体数据;针对所述图源执行第二预设处理得到所述BMP数据源,所述第二预设处理包括以下至少一种操作:VRDS限制对比度自适应直方图均衡、混合偏微分去噪、VRDS Ai弹性变形处理。
可见,本示例中,医学成像装置会对扫描图像进行筛选得到DICOM数据,然后解析得到Texture 2D/3D图像体数据,最后通过均衡、去噪、弹性变形中的至少一种进行处理,最终获得符合医学影像要求的BMP数据源。
在本可能的示例中,所述VRDS限制对比度自适应直方图均衡包括:区域噪音比度限幅、全局对比度限幅;将图源的局部直方图划分多个分区,针对每个分区,根据该分区的邻域的累积直方图的斜度确定变换函数的斜度,根据该变换函数的斜度确定该分区的像素值周边的对比度放大程度,然后根据该对比度放大程度进行限度裁剪处理,产生有效直方图的分布,同时也产生有效可用的邻域大小的取值,将这些裁剪掉的部分直方图均匀的分布到直方图的其他区域。
所述混合偏微分去噪包括:不同于高斯低通滤波(对图像的高频成分不加区别的减弱,去噪的同时会产生图像边缘模糊化),自然图像中的物体所形成的等照度线(包括边缘)应该是足够光滑顺畅的曲线,即这些等照度线的曲率的绝对值应该足够小,当图像受到噪声污染后,图像的局部灰度值会发生随机起伏,导致等照度线的不规则震荡,形成局部曲率很大的等照度线,根据这一原理,设计通过VRDS Ai曲率驱动和VRDS Ai高阶混合去噪,实现即可保护图像边缘、又可以避免平滑过程中出现阶梯效应的混合偏微分去噪模型。
所述VRDS Ai弹性变形处理包括:在原有点阵上,叠加正负向随机距离形成差值位置矩阵,然后在每个差值位置上的灰度,形成新的点阵,可以实现图像内部的扭曲变形,另外再对图像进行旋转、扭曲、平移等操作。

在本可能的示例中,所述医学成像装置综合所述第一数据、所述第二数据、所述动脉的除所述交叉位置的数据以及所述静脉的除所述交叉位置的数据,得到所述目标医学影像数据,包括:所述医学成像装置综合所述第一数据、所述第二数据、所述动脉的除所述交叉位置的数据以及所述静脉的除所述交叉位置的数据,得到第二医学影像数据;针对所述第二医学影像数据执行第一预设处理得到目标医学影像数据,所述第一预设处理包括以下至少一种操作:2D边界优化处理、3D边界优化处理、数据增强处理,所述目标医学影像数据包括所述目标器官的数据集合和所述动脉的数据集合以及所述静脉的数据集合;
其中,所述2D边界优化处理包括多次采样获取低分辨率信息和高分辨率信息,其中,低分辨率信息能够提供分割目标在整个图像中上下文语义信息,即反映目标与环境之间关系的特征,这些特征用于物体类别判断,高分辨率信息用于为分割目标提供更加精细的特征,如梯度等。
其中,所述3D边界优化处理包括:3D卷积、3D最大池化和3D向上卷积层,输入数据的大小为a1、a2、a3,通道数为c,过滤器大小为f,即过滤器维度为f*f*f*c,过滤器数量为n,则3维卷积最终输出为:
(a1-f+1)*(a2-f+1)*(a3-f+1)*n
具有分析路径和合成路径。在分析路径中,每一层包含两个3*3*3的卷积核,每一个都跟随一个激活函数(Relu),然后在每个维度上有2*2*2的最大池化合并两个步长。在合成路径中,每个层由2*2*2的向上卷积组成,每个维度上步长都为2,接着,两个3*3*3的卷积,然后Relu。然后在分析路径中从相等分辨率层的shortcut连接提供了合成路径的基本高分辨特征。在最后一层中,1*1*1卷积减少了输出通道的数量。
其中,所述数据增强处理包括以下任意一种:基于任意角度旋转的数据增强、基于直方图均衡的数据增强、基于白平衡的数据增强、基于镜像操作的数据增强、基于随机剪切的数据增强和基于模拟不同光照变化的数据增强。

具体实现中,交叉位置的交叉复杂度可以根据交叉区域的曲率范围计算得到,曲率范围越大,说明动脉与静脉的接触情况越紧密复杂,对应交叉复杂度越高。交叉位置的分区具体可以按照曲率半径进行分区,如曲率半径a1到a2范围内的区域为第一交叉分区,曲率半径a2到a3范围内的区域为第二交叉分区。每个交叉分区的数据的筛选策略可以是通过卷积运算或者稀疏处理等算法执行,目的是保证显示效果的基础上减少数据量以提高计算效 率。
其中,所述交叉血管网络模型通过以下操作实现动脉和静脉的数据分离:(1)提取交叉位置的融合数据;(2)针对每个融合数据基于预设数据分离算法分离该融合数据,得到相互独立的动脉边界点数据和静脉边界点数据;(3)将处理后得到的多个动脉边界点数据整合为第一数据,将处理后得到的多个静脉边界点数据整合为第二数据。
