另外,说明书中所描述的特点、操作或者特征可以以任意适当的方式结合形成各种实施方式。同时,方法描述中的各步骤或者动作也可以按照本领域技术人员所能显而易见的方式进行顺序调换或调整。因此,说明书和附图中的各种顺序只是为了清楚描述某一个实施例,并不意味着是必须的顺序,除非另有说明其中某个顺序是必须遵循的。
本文中为部件所编序号本身,例如“第一”、“第二”等,仅用于区分所描述的对象,不具有任何顺序或技术含义。而本申请所说“连接”、“联接”,如无特别说明,均包括直接和间接连接(联接)。
目前,由于Color、Power或者多普勒频谱等模式原本是用于提供血流的信息,因此当被应用到介入操作的超声图像模式时,存在很多缺点。以Color模式的超声成像为例进行说明。如图1所示,超声成像系统交替执行一帧二维成像扫描和一帧血流成像扫描,然后根据前后的一帧二维成像扫描和一帧血液成像扫描的回波信号来生成一帧彩色多普勒血流超声图像,例如依次进行第1帧二维成像扫描、第1帧血流成像扫描、第2帧二维成像扫描、第2帧血流成像扫描、……、第n帧二维成像扫描、第n帧血流成像扫描、……;第1帧二维成像扫描和第1帧血流成 像扫描用于生成第1帧的彩色多普勒血流超声图像,第2帧二维成像扫描和第2帧血流成像扫描用于生成第2帧的彩色多普勒血流超声图像,……,第n帧二维成像扫描和第n帧血流成像扫描用于生成第n帧的彩色多普勒血流超声图像,……。可以看到,在Color模式的超声成像,血流成像的扫描和计算会占用大量的资源,如果运用到用于引导医生进行穿刺介入操作的超声引导图像中,会使得图像帧率明显下降。通常为了获取更好的血流信号、更丰富的血流信息,血流成像所占用的发射能量会明显超过二维信号。受限于探头温升等法规,单位时间内可以发出的能量存在上限,血流成像占用的多,二维成像就必须减少。因此,二维信号的信噪比会有损失,直接表现是二维图像质量下降,影响组织及穿刺针的显示。另外,通常流血信息是以伪彩的形式覆盖在二维图像上,使得医生无法看法当前位置的二维图像。
为解决上述问题,本申请提供如图2所示的示例性构思,超声成像系统交替执行一帧血流成像扫描、连续的多帧二维成像扫描,例如M帧二维成像扫描,M为大于1的整数。每一帧血流成像扫描用于确定血管位置,并依次与其后的多帧二维成像扫描的每一帧来生成包含血管位置的超声图像。可以看到,由于血流成像扫描的时间大大减少,血流成像扫描和计算占用的资源也大大减少,这使得图像帧率明显上升,二维图像质量提高。当然上述的构思可以有多种的变形方案,例如这里的一帧血流成像扫描也可以替换成连续的多帧血流成像扫描,只要保证这连续的多帧血流成像扫描的帧数小于连续的多帧二维成像扫描的数量,那么还是会比Color模式的超声成像的图像帧率和二维图像质量高;再例如由于血流成像扫描是用于确定血管位置,因此这里的血流成像扫描可以替换成其他能够用于确定血管位置的扫描类型;再例如由于这里的二维成像扫描是用于生成生物体的内部组织结构的超声图像,因此这里的二维成像扫描也可以替换成其他能够生成生物体的内部组织结构的超声图像的扫描类型,以及其他维度的超声图像,例如三维,四维超声图像。
请参考图3,为一种实施例的超声成像系统的结构示意图。超声成像系统可以包括超声探头10、发射/接收控制电路20、回波处理单元30、处理器40和显示单元50。
超声探头10包括多个阵元,用于实现电脉冲信号和超声波的相互转 换,从而实现向被检测生物组织60(例如人体或动物体中的生物组织)发射超声波并接收组织反射回的超声回波。超声探头10所包括的这多个阵元,可以排列成一排构成线阵,或排布成二维矩阵构成面阵,这多个阵元也可以构成凸阵列。阵元可根据激励电信号发射超声波,或将接收的超声波变换为电信号。因此每个阵元可用于向感兴趣区域的生物组织发射超声波,也可用于接收经组织返回的超声回波。在进行超声检测时,可通过发射序列和接收序列控制哪些阵元用于发射超声波,哪些阵元用于接收超声波,或者控制阵元分时隙用于发射超声波或接收超声回波。参与超声波发射的所有阵元可以被电信号同时激励,从而同时发射超声波;或者参与超声波发射的阵元也可以被具有一定时间间隔的若干电信号激励,从而持续发射具有一定时间间隔的超声波。
发射/接收控制电路20一方面用于控制超声探头10向生物组织60发射超声波束,另一方面用于控制超声探头10接收超声波束经组织反射的超声回波。具体实施例中,发射/接收控制电路20用于产生发射序列和接收序列,并输出至超声探头。发射序列用于控制超声探头10中多个阵元中的部分或者全部向生物组织60的感兴趣目标发射超声波,发射序列的参数包括发射用的阵元数和超声波发射参数(例如幅度、频率、发波次数、发射间隔、发射角度、波型和/或聚焦位置等)。接收序列用于控制多个阵元中的部分或者全部接收超声波经组织后的回波,接收序列的参数包括接收用的阵元数以及回波的接收参数(例如接收角度、深度等)。对超声回波的用途不同或根据超声回波生成的图像不同,发射序列中的超声波参数和接收序列中的回波参数也有所不同。
回波处理单元30用于对超声探头10接收到的超声回波信号进行处理,例如对超声回波信号进行滤波、放大、波束合成等处理,得到处理后的超声回波信号。在具体实施例中,回波处理单元30可以将处理后的超声回波信号输出给处理器40,也可以将超声回波信号的数据先存储在一存储器中,在需要基于超声回波数据进行运算时,处理器40从存储器中读取超声回波信号的数据。本领域技术人员应当理解,在有的实施例中,当不需要对超声回波信号进行滤波、放大、波束合成等处理时,回波处理单元30也可以省略。
处理器40用于获取超声回波信号,并采用相关算法得到所需要的参数或图像。
显示单元50可以用于显示信息,例如显示由处理器40计算得到的参数和图像等。本领域技术人员应当理解,在有的实施例中,超声成像系统本身可以不集成显示单元,而是连接一个计算机设备(例如电脑),通过计算机设备的显示单元(例如显示屏)来显示信息。
以上是超声成像系统的的一个基本结构。
本申请一实施例中发射/接收控制电路20用于控制超声探头10执行第一扫描模式对目标组织进行扫描以及接收第一扫描模式的回波信号,和控制超声探头10执行第二扫描模式对所述目标组织进行扫描以及接收第二扫描模式的回波信号,其中第二扫描模式对应的扫描帧数大于第一扫描模式对应的扫描帧数。一实施例中第一扫描模式对应的扫描帧数可以是一帧,也可以是多帧。一实施例中第一扫描模式和第二扫描模式不同。这里的第一扫描模式是用于检测目标组织内的血管位置,例如第一扫描模式可以是C扫描模式或D扫描模式,其中D扫描模式可以是PW扫描模式和CW扫描模式等。第一扫描模式可以使用常规聚焦方式,也可以使用平面波方式等。这里的第二扫描模式是用于检测目标组织的内部组织结构,例如第二扫描模式可以是B扫描模式。第一扫描模式和第二扫描模式的扫描范围可以相同,这样可以保证医生在超声图像上的可视范围内的血管位置都够得到确定,不会产生遗漏。
处理器40则根据第一扫描模式的回波信号确定目标组织内的血管位置,和根据第二扫描模式的回波信号生成所述目标组织对应的第一超声图像。显示单元50则将所述血管位置显示在第一超声图像上。
如图4所示,一实施例的超声成像系统可以包括一轮或多轮扫描,发射/接收控制电路20控制超声探头10执行这多轮扫描;在每一轮扫描中,发射/接收控制电路20都控制超声探头10执行第一扫描模式对目标组织进行扫描以及接收第一扫描模式的回波信号,和执行所述第二扫描模式对目标组织进行扫描以及接收第二扫描模式的回波信号,处理器40把根据同一轮的第一扫描模式的回波信号所确定的血管位置融合在根据同一轮的第二扫描模式的回波信号所生成的第一超声图像上,并通过显示单元50来显示。具体地,例如对于每一轮扫描,发射/接收控制电路20对第二扫描模式对应的扫描帧数计数以判断是否达到设定帧数,若未达到设定帧数,则通知显示单元50将血管位置显示在第一超声图像上,若达到设定帧数,则发射/接收控制电路20控制超声探头10进行下一轮 扫描。以图4中为例,超声成像系统交替执行N帧的第一扫描模式的扫描和M帧的第二模式的扫描,其中N和M都是正整数且M大于N。换句话说,超声成像系统的每轮扫描都包括N帧的第一扫描模式的扫描和M帧的第二扫描模式的扫描。如图5所示,以其中任意一轮的扫描为例,通过N帧的第一扫描模式的扫描来确定血管位置,通过M帧的第二扫描模式的扫描来依次生成并显示M帧的第一超声图像,在显示这M帧中的每一帧第一超声图像时,都将上述通过N帧的第一扫描模式的扫描所确定的血管位置显示在第一超声图像上。可以将上述的设定帧数设置为M+1,则发射/接收控制电路20对第二扫描模式对应的扫描帧数计数以判断是否达到设定帧数M+1,若未达到设定帧数M+1,则通知显示单元50将血管位置显示在第一超声图像上,若达到设定帧数M+1,即下一帧若还要进行第二扫描模式的扫描,则帧数将会达到第M+1帧,那么这时候发射/接收控制电路20控制超声探头10进行下一轮扫描,而不是进行这第M+1帧的第二扫描模式的扫描。
本申请实施例通过扫描帧数相对少的第一扫描模式来确定血管位置,通过扫描帧数相对多的第二扫描模式来生成关于目标组织的内部组织结构的第一超声图像,这样可以有效地提高最终所显示的超声图像的帧率和质量。
下面对处理器40如何确定血管位置进行进一步的说明。
处理器40根据第一扫描模式的回波信号确定所述目标组织内的血管位置,可以有多种实现方式,例如其中一种实现方式可以包括:接收第一扫描模式从目标组织返回的回波信号,从该回波信号中生成血流信号,根据该血流信号确定所述血管位置。从回波信号中生成血流信号可以使用现在的算法也可以使用未来出现的算法,例如以第一扫描模式为C扫描模式为例,可以通过对回波信号进行波束合成、正交解调、滤波、自相关计算、速度能量估计以及后处理,从而生成血流信号;有血流信号的位置,即可以判定该位置处有血管;例如再以第一扫描模式为PW扫描模式为例,可以通过接收到的回波信号来计算各位置的PW信号强度,并根据各位置的PW信号强度来判断是否有血管,比如设定一预设阈值,PW信号强度大于预设阈值的位置被判定为该位置有血管,PW信号强度小于预设阈值的位置则判定该位置没有血管。
处理器40确定了血管位置后,可以根据血管位置生成目标掩模图像, 并将该目标掩模图像融合在第一超声图像上,显示器通过显示融合后的图像,从而可以实现将血管位置显示在第一超声图像。例如,有血管的位置,就将掩模图像该位置的像素值设置为非零值,例如1,反之,若没有血管的位置,就将掩模图像该位置的像素值设置为零,这样遍历整帧图像,生成的掩模图像即为上述的目标掩模图像。由于第一扫描模式的帧数可以为一帧也可以为多帧,下面根据这两种情况分别说明如何具体生成目标掩模图像。
一实施例中,当第一扫描模式对应的扫描帧数为1时,则处理器40根据血管位置生成目标掩模图像可以包括:根据这一帧扫描对应的血管位置得到一个初始掩模图像,并将这个初始掩模图像确定为目标掩模图像。
一实施例中,当第一扫描模式对应的扫描帧数为多帧,例如N帧,N为大于1的整数,则处理器40根据血管位置生成目标掩模图像可以包括:根据这N帧扫描对应的血管位置生成N个初始掩模图像;将这N个初始掩模图像按照预设方式生成所述目标掩模图像,其中,所述预设方式包括加权相加的方式和取最大值的方式中的至少一种。请参照图6,不妨以两帧为例,第一扫描模式的这两帧扫描对应的血管位置生成两个初始掩模图像,请参照图6(a),假设通过权重系数分别为0.5的加权相加的方式来生成目标掩模图像,则目标掩模图像的像素值分别为:0*0.5+0*0.5即0,0*0.5+0*0.5即0,1*0.5+0*0.5即0.5,1*0.5+1*0.5即1;请参照图6(b),假设通过取最大值的方式来生成目标掩模图像,则目标掩模图像像素值分别为:0和0中取0,0和0中取0,1和0中取1,1和1中取1,其中,目标掩模图像像素值为0时,则代表此位置无血管,目标掩模图像像素值不为0时,则代表此位置有血管。
下面对如何具体将血管位置显示在第一超声图像上进行进一步的说明。
处理器40可以驱动显示单元50将血管位置显示在第一超声图像上。具体的方式可以包括多种,下面试举两种。
方式一,将血管位置以伪彩的方式显示在第一超声图像上,伪彩的方式可以是通过预设透明度渲染上述血管位置,该透明度对应的颜色值不做限定。例如请参照图7(a)的例子,是用半透明的伪彩来将血管位置进行示意,以供医生查看。
方式二,将血管位置以边界描绘的方式显示在所述第一超声图像上,所述边界描绘的方式用于通过实线和虚线中的至少一种线条描绘血管的边界。例如请参照图7(b)的例子,是用虚线来描绘血管的边界以对血管位置进行示意,从而可供医生查看。
本申请实施例还提供一种计算机可读存储介质,该计算机可读存储介质存储有多条程序指令,该多条程序指令被处理器40调用执行后,可执行本申请各个实施例中的血管位置的显示方法中的部分步骤或全部步骤或其中步骤的任意组合。
一个实施例中,该计算机可读存储介质可为存储器,其可以是闪存卡、固态存储器、硬盘等非易失性存储介质。
本申请实施例中,前述的超声成像系统中的处理器40可以通过软件、硬件、固件或者其组合实现,可以使用电路、单个或多个专用集成电路(application specific integrated circuits,ASIC)、单个或多个通用集成电路、单个或多个微处理器、单个或多个可编程逻辑器件、或者前述电路或器件的组合、或者其他适合的电路或器件,从而使得该处理器40可以执行前述各个实施例中的血管位置的显示方法的相应步骤。
本申请还提出一种血管位置的显示方法,该显示方法可以用于超声介入引导,供医生在进入穿刺等介入操作时查看血管位置;请参照图8,一实施例的血管位置的显示方法可以包括步骤110到步骤150,下面具体说明。
步骤110:通过第一扫描模式对目标组织进行扫描以确定所述目标组织内的血管位置。
请参照图9,在一实施例中步骤110通过第一扫描模式对目标组织进行扫描以确定所述目标组织内的血管位置可以包括步骤111~步骤113。
步骤111:接收从所述目标组织返回的回波信号。
步骤112:从所述回波信号中生成血流信号。
步骤113:根据所述血流信号确定所述血管位置。
步骤130:通过第二扫描模式对所述目标组织进行扫描以获取所述目标组织对应的第一超声图像。
步骤130中的第二扫描模式对应的扫描帧数大于步骤110中的第一扫描模式对应的扫描帧数。
一实施例中第一扫描模式和第二扫描模式不同。这里的第一扫描模式是用于检测目标组织内的血管位置,例如第一扫描模式可以是C扫描模式或D扫描模式,其中D扫描模式可以是PW扫描模式和CW扫描模式等。第一扫描模式可以使用常规聚焦方式,也可以使用平面波方式等。这里的第二扫描模式是用于检测目标组织的内部组织结构,例如第二扫描模式可以是B扫描模式。第一扫描模式和第二扫描模式的扫描范围可以相同,这样可以保证医生在超声图像上的可视范围内的血管位置都够得到确定,不会产生遗漏。
步骤150:将所述血管位置显示在所述第一超声图像上。在一实施例中,步骤150将血管位置显示在所述第一超声图像上包括以下至少一种方式:
方式一,将所述血管位置以伪彩的方式显示在所述第一超声图像上,所述伪彩的方式用于通过预设透明度渲染所述血管位置;
方式二,将所述血管位置以边界描绘的方式显示在所述第一超声图像上,所述边界描绘的方式用于通过实线和虚线中的至少一种线条描绘血管的边界。
请参照图10,一实施例中的显示方法还可以包括图像融合步骤140;请参照图11,图像融合步骤140可以包括步骤141和步骤142。
步骤141:根据所确定的血管位置生成目标掩模图像。第一扫描模式的帧数可以为一帧也可以为多帧,下面根据这两种情况分别说明如何具体生成目标掩模图像。例如,当第一扫描模式对应的扫描帧数为1时,则根据血管位置生成目标掩模图像可以包括:根据这一帧扫描对应的血管位置得到一个初始掩模图像,并将这个初始掩模图像确定为目标掩模图像。例如,当第一扫描模式对应的扫描帧数为多帧,例如N帧,N为大于1的整数,则根据血管位置生成目标掩模图像可以包括:根据这N帧扫描对应的血管位置生成N个初始掩模图像;将这N个初始掩模图像按照预设方式生成所述目标掩模图像,其中,所述预设方式包括加权相加的方式和取最大值的方式中的至少一种。
步骤142:将目标掩模图像融合在第一超声图像上。这样步骤150就可以通过显示融合后的图像来实现将血管位置显示在第一超声图像上。
一实施例的显示方法可以包括多轮扫描,每一轮扫描都包括所述的步骤110即通过第一扫描模式对目标组织进行扫描以及所述的步骤130 即通过第二扫描模式对所述目标组织进行扫描;其中,将同一轮扫描中所确定的目标组织内的血管位置显示在同一轮扫描中所获取的第一超声图像上。具体在实现时可以这样来实现每轮扫描的切换:对第二扫描模式对应的扫描帧数计数以判断是否达到设定帧数,若未达到设定帧数,则将血管位置显示在第一超声图像上,若达到设定帧数,则进行下一轮扫描。例如可以将上述的设定帧数设置为M+1,对于每一轮扫描,对第二扫描模式对应的扫描帧数计数以判断是否达到设定帧数M+1,若未达到设定帧数M+1,则将根据本轮扫描所确定的血管位置显示根据本轮扫描所生成在第一超声图像上,若达到设定帧数M+1,即下一帧若还要进行第二扫描模式的扫描,则帧数将会达到第M+1帧,那么这时候进行下一轮扫描,而不是进行这第M+1帧的第二扫描模式的扫描。
在上述实施例的基础上,本实施例增加了介入物例如穿刺针的显示。
因此一实施例的发射/接收控制电路还20控制超声探头10执行第三扫描模式对刺入目标组织内的介入物进行扫描,以及接收第三扫描模式的回波信号;处理器40则根据第三扫描模式的回波信号生成所述介入物对应的第二超声图像,并将所述第二超声图像和所述第一超声图像融合以在显示单元50中显示。这样如图12所示,显示单元50可以在超声图像中显示血管位置和介入物。在一实施例中,第三扫描模式和第一扫描模式不同,而第三扫描模式可以和第二扫描模式相同。
因此,展开来说就是:发射/接收控制电路20控制超声探头10执行第一扫描模式对目标组织进行扫描以及接收第一扫描模式的回波信号,控制超声探头10执行第二扫描模式对所述目标组织进行扫描以及接收第二扫描模式的回波信号,和控制超声探头10执行第三扫描模式对所述目标组织内的介入物进行扫描以及接收第三扫描模式的回波信号;其中所述第二扫描模式对应的扫描帧数大于所述第一扫描模式对应的扫描帧数。处理器40则根据上述第一扫描模式的回波信号确定所述目标组织内的血管位置,根据上述第二扫描模式的回波信号生成所述目标组织对应的第一超声图像,和根据上述第三扫描模式的回波信号生成所述介入物对应的第二超声图像。显示单元50则将上述血管位置显示在第一超声图像和第二超声图像融合的图像上。
类似地,显示单元50将血管位置显示在第一超声图像和第二超声图 像融合的图像上,包括以下至少一种方式:
方式一,将血管位置以伪彩的方式显示在第一超声图像和第二超声图像融合的图像上,上述伪彩的方式用于通过预设透明度渲染上述血管位置;
方式二,将血管位置以边界描绘的方式显示在第一超声图像和第二超声图像融合的图像上,上述边界描绘的方式用于通过实线和虚线中的至少一种线条描绘血管的边界。
相应地,请参照图13,一实施例的显示方法还包括步骤160和步骤170。
步骤160:通过第三扫描模式对刺入所述目标组织内的介入物进行扫描以获取所述介入物对应的第二超声图像。
步骤170:将所述第二超声图像和所述第一超声图像融合显示。
本实施例通过还引入显示介入物,实现了医生进行超声介入引导时,所观看的超声图像在显示血管位置的同时还显示介入物,这可以帮助医生更好地设计介入路径,避免意见刺破血管。
因此,展开来说就是,一实施例的显示方法,如图14所示可以包括步骤210到步骤270,下面具体说明。
步骤210:通过第一扫描模式对目标组织进行扫描以确定所述目标组织内的血管位置。
步骤230:通过第二扫描模式对所述目标组织进行扫描以获取所述目标组织对应的第一超声图像。
步骤230中的第二扫描模式对应的扫描帧数大于步骤210中的第一扫描模式对应的扫描帧数。
步骤250:通过第三扫描模式对刺入所述目标组织内的介入物进行扫描以获取所述介入物对应的第二超声图像。
步骤270:将所述血管位置显示在所述第一超声图像和第二超声图像融合的图像上。
上述步骤中,步骤210可参考步骤110,两者相同;步骤230可参考步骤130,两者相同;步骤250可参考步骤160,两者相同;步骤270可参考步骤150和步骤170,步骤270所实现的效果与步骤150和步骤170配合起来所实现的效果相同或类似。
以上就是本申请的大体内容,在实施例本申请后,可以使得医生不需要中途再对仪器进行操作,就可以得到并实时在超声图像上刷新血管位置,为医生设计介入方案提供参考,提高了用户的易用性和工作效率。
