Description

超声成像的方法、超声成像设备以及穿刺导航系统 技术领域
本申请涉及医疗器械领域，尤其涉及一种超声成像的方法、超声成像设备以及穿刺导航系统。
背景技术
随着科学技术的发展，超声波的指向性能够对病变组织进行相当准确的定位，而且能实时观察组织解剖结构的动态变化，其准确性和安全性相对其他影像检查手段具有不可比拟的优势。超声能够清晰的显示人体内部组织结构，超声引导穿刺技术应运而生，这种技术就是在实时超声影像的监视和引导下，针对体内病变或目标进行穿刺的临床技术。具体做法是在超声的引导下，避开重要脏器及较大的血管和神经，将穿刺针准确地穿入病变组织内进行治疗或通过吸出、切割出少量细胞或组织进行病理检查，或将穿刺针穿刺到神经附近注释麻醉药物等，这就在最大程度上避免了对周围组织的损伤，穿刺后还能立即对穿刺部位、穿刺路径以及麻醉药物的扩散进行观察，及时发现可能出现的出血等现象，用最短的时间加以处理，避免引起更加严重的并发症。
超声穿刺导航可以实时显示穿刺针在组织内的运动情况，为穿刺路径选择提供依据，是超声辅助治疗的重要手段。但是常规超声引导穿刺严重依赖操作者的经验与超声仪器性能，可能存在穿刺次数较多和操作用时较长等问题，进而导致并发症发生率增加。例如，探头发出的超声波实际上非常狭窄，是从探头中间的小缝隙发出的，穿刺针和探头发出的超声波不在一个平面内，因此无法通过超声成像对穿刺进行有效引导。另外，当探头和皮肤并不垂直时，穿刺针需要从相对于探头的侧方向进针，穿刺针和探头并不共面。若超声引导下神经阻滞，如果针尖没有完整显示，可能存在神经损伤。而对于一些穿刺治疗也存在比较大困难，例如，由于抽吸针针管很小，穿刺针在到达超声图像2-3cm深度时就显示不清晰，因而无法有效避开重要的血管和神经等。

具体实施方式
本申请实施例提供了一种声成像的方法以及超声成像设备，用于提高操作准确性。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
图1为本申请实施例中的超声成像设备10的结构框图示意图。该超声成像设备10可以包括探头100、发射电路101、发射/接收选择开关102、接收电路103、波束合成电路104、处理器105和显示器106。发射电路101可以激励探头100向目标区域发射超声波。接收电路103可以通过探头100接收从目标区域返回的超声回波，从而获得超声回波信号/数据。该超声回波信号/数据经过波束合成电路104进行波束合成处理后，送入处理器105。处理器105对该超声回波信号/数据进行处理，以获得目标对象的超声图像或者介入性物体的超声图像。处理器105获得的超声图像可以存储于存储器107中。这些超声图像可以在显示器106上显示。
本申请的一个实施例中，前述的超声成像设备10的显示器106可为触摸显示屏、液晶显示屏等，也可以是独立于超声成像设备10之外的液晶显示器、电视机等独立显示设备，也可为手机、平板电脑等电子设备上的显示屏，等等。
本申请的一个实施例中，前述的超声成像设备10的存储器107可为闪存卡、固态存储器、硬盘等。
本申请的一个实施例中，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105调用执行后，可执行本申请各个实施例中的超声成像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107，其可以是闪存卡、固态存储器、硬盘等非易失性存储介质。
本申请的一个实施例中，前述的超声成像设备10的处理器105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105可以执行本申请的各个实施例中的超声成像方法的相应步骤。
下面对本申请中的超声成像方法进行详细描述。
需要说明的是，结合图1所示的超声成像设备10的结构框图示意图，本申请实施例提供的超声成像方法可应用于如下应用场景：操作人员将探头100放在待穿刺部位的体表，从探头100的侧面插入穿刺针，操作人员通过显示器106，可以看到组织结构等，同时也可以隐约看到穿刺针或穿刺针的针尖在组织结构内所处的位置。
基于此，请参阅图2，本申请实施例提供的一种超声成像方法，该方法应用于超声成像设备10，超声成像方法实施例包括：
201、向目标区域发射超声波，并接收目标区域返回的超声回波，以获得超声回波数据。
首先，为获取目标区域的图像，操作人员可以将探头100放在目标区域，向目标区域发射超声波，并接收目标区域反射的超声回波，以得到超声回波数据。根据目标区域的组织结构的不同，所接收到的超声回波数据也不同。
具体地，如图3所示，可以是处理器105控制打开发射/接收选择开关102，并控制发射电路101通过探头100向目标区域发射超声波，并通过探头100 接收超声回波，并传送至接收电路103，即可以理解为接收电路103可以通过探头100接收从目标区域返回的超声回波，从而获得超声回波数据。
202、根据超声回波数据生成超声图像。
超声回波数据经过波束合成电路104进行波束合成处理后，传输至处理器105，处理器105对该超声回波数据进行处理，以获得目标区域的超声图像。
203、获取介入性物体的位置信息。
本实施例中，处理器105可获取待插入或者插入目标对象的介入性物体的位置信息，并根据该位置信息确定目标成像参数。该位置信息可以是该介入性物体相对于探头的位置关系。
在临床操作中，当介入性物体插入或待插入目标对象时，超声成像设备10对该介入性物体进行定位，以获取该介入性物体的位置信息。
为便于描述，本申请实施例中，以介入性物体为穿刺针为例进行说明，对应的，介入性物体的位置信息可包括穿刺针的针尖位置。实际应用中，该介入性物体可以为其他物体，具体此处不做限定。
需要说明的是，实际应用中，获取该介入性物体的位置信息的方式有多种，包括通过电磁导航技术、图像模式识别技术、红外或者激光技术等，具体此处不做限定。
在一个实施例中，可通过电磁导航技术得到该介入性物体的位置信息。该获取待插入或者插入目标对象的介入性物体的位置信息包括：处理器105检测该穿刺针磁化后产生的磁感应强度；根据该磁感应强度确定该穿刺针的针尖位置。
电磁导航技术，为利用空间分布的磁场，根据传感器在磁场中获得的数据，对磁场中物体实现定位的技术。可以理解为利用磁场对非屏蔽物体的穿透性来实现非可视状态下的实时定位技术。示例性地，基于磁场感应定位技术确定穿刺针的位置信息的过程包括：首先监测探头100周边的磁场强度，记录初始磁场强度。然后操作人员可通过磁化器将穿刺针磁化，得到磁化后的穿刺针。当磁化后的穿刺针靠近超声成像设备10的探头100时，由于该磁化后的穿刺针会产生磁场，且如图4所示，一个实施例中，探头100的内部可集成有磁敏材料组成的磁场传感器阵列201，故磁化后的穿刺针会影响磁场传感器阵列201 周围的磁场。因此磁场传感器阵列检测出穿刺针产生的磁场的磁感应强度，使得超声成像设备10根据该磁感应强度的变化值确定磁场传感器阵列周围的磁场的变化值，并基于该磁场的变化值实时计算穿刺针的针尖的坐标信息和方位信息，以得到穿刺针的空间坐标，并将空间坐标转换为相对超声图像所在平面的平面坐标，可以结合超声图像，生成穿刺针在超声图像中对应的位置信息。
应理解，探头100中可以包括磁传感器，以检测探头100周围的磁场强度。
示例性地，首先监测探头100周边的磁场强度B(b)，将穿刺针磁化后，检测因磁化的穿刺针引起的探头周边磁场变化强度B(t)，根据原来的探头周边磁场强度和变化后的探头周边磁场强度计算出穿刺针的磁场B(n)＝B(t)-B(b)，将计算得到的穿刺针的磁场强度和预置的磁场数据表进行比较计算出穿刺针相对于探头的位置和角度，计算穿刺针的针尖和针尾的空间坐标B(0)＝F(x 0，y 0，z 0)和B(1)＝F(x 1，y 1，z 1)，然后系统将针尖针尾的空间坐标转换直接映射到相对超声平面的坐标p(0)＝F(x 0，y 0，0)和p(1)＝F(x 1，y 1，0)，即得到穿刺针的坐标信息。
因此，在本申请实施例中，实时监测穿刺针的位置信息，使临床医生准确地看见超声图像引导穿刺下的穿刺针针尖的位置。
在一个实施例中，可通过图像模式识别技术得到该介入性物体的位置信息。例如，当穿刺针插入目标对象后，超声成像设备10通过探头100发射超声波，得到带有穿刺针和组织结构等的B型超声图像(以下简称B超图像)，对该B超图像进行图像增强和均衡化处理，并在该B超图像中通过图像模式识别的方式确定穿刺针的位置。
在一个实施例中，可通过红外或者激光技术得到该介入性物体的位置信息。例如，可通过红外或者激光探测该介入性物体介入的深度、位移等等，以确定在超声图像中穿刺针的位置。
综上，本申请实施例中，定位介入性物体的方式有多种，此处不再一一赘述。
204、根据介入性物体的位置信息生成引导图像。
在确定穿刺针的位置信息后，可以确定穿刺针的针尖坐标与针尾坐标，将针尖坐标与针尾坐标映射到超声图像中，生成引导图像，根据穿刺针的位置信 息生成引导图像。
205、显示超声图像和引导图像。
在显示器上显示超声图像与引导图像。一个实施例中，还可根据对穿刺针的监测进行实时更新显示。
引导图像可以包括指示穿刺针所在区域的第一引导图，指示穿刺针针尖所在区域的第二引导图，指示所述穿刺目标所在区域的第三引导图，和/或指示所述穿刺针的穿刺路径的第四引导图，以下结合超声图像对引导图进行示例性说明。
穿刺可以分为平面内穿刺与平面外穿刺。平面内穿刺为在探头100发出的声束内进行的穿刺，平面内穿刺的穿刺路径在超声图像平面内。平面外穿刺的穿刺路径为穿刺针整体或局部在探头100发出的声束以外进行穿刺的过程，通常平面外穿刺在超声图像中仅能显示部分穿刺针或穿刺针的针尖。在本申请实施例中，针对平面外穿刺与平面内穿刺都可以生成引导图像，并映射到超声图像中。
需要说明的是，平面外穿刺的超声图像中可以显示部分穿刺针或穿刺针的针尖，本申请仅以穿刺针的针尖为例进行说明。另外，本申请实施例中的引导图以虚线为例进行示例性说明，实际的引导图像中所包括的线条可以是虚线、实线或其他线条、其他颜色的引导图，具体根据实际应用场景调整，此处并不作限定。
例如，第一引导图可以如图5以及图6所示。第一引导图为穿刺针所在区域的引导图，平面内穿刺如图5中的第一引导图401或者平面外穿刺如图6中的第一引导图401。其中，第一引导图401包括穿刺针所在的区域。当平面外进行穿刺时，只有在针已经达到或者通过成像切面时，才能看到针和超声成像平面交点的显影，可以通过电磁导航技术确定穿刺针的位置信息，当仅能显示穿刺针的针尖时，根据穿刺针的位置信息，生成穿刺针的第一引导图，标识穿刺针所在的区域。因此，可以根据穿刺针所在区域的引导图，确定穿刺针的穿刺路径。
第二引导图可以如图7以及图8所示，平面内穿刺的第二引导图可以如图7所示的402，平面外穿刺的第二引导图可以如图8所示的402。标识穿刺针 的针尖，因此，操作人员可以清楚地获知针尖所处的位置，根据针尖的位置，确定穿刺针的穿刺路径。让临床医生准确地看见超声图像引导穿刺下的针尖，以此能更好地确认穿刺针与穿刺目标的相对位置，及时调整穿刺针，更准确地进行穿刺。
第三引导图为穿刺目标所在区域的引导图，平面内穿刺的第三引导图可以如图9所示的403，平面外穿刺的第三引导图可以如图10所示的403。其中，平面内穿刺与平面外穿刺都能确定穿刺目标所处的区域，通过第三引导图标识穿刺目标，可以使操作人员清楚地获知穿刺目标所在的区域，进行穿刺时，根据穿刺目标所处的位置，及时调整穿刺针的角度以及位置，提高穿刺的准确性。
第四引导图为穿刺针指示穿刺针穿刺路径的引导图，平面内穿刺的第四引导图可以如图11所示的404，平面外穿刺的第四引导图可以如图12所示的404。具体地，第四引导图可以是引导线，处理器105可以根据穿刺针的位置信息，得到穿刺针的针尖坐标以及针尾坐标，并根据针尖坐标以及针尾坐标计算出穿刺针到穿刺目标的引导线。可以以针尖的位置作为起点，计算出穿刺针针尖穿刺到穿刺目标的距离。如图11与图12所示为例，第四引导图可以是引导线，引导线上可以标记刻度，即第四引导图上可以包括刻度标识。可以是根据超声图像的物理像素值计算每个刻度值对应的像素数量，按照计算出来的刻度值在引导线上标记刻度点，其中，刻度可以通过线段或圆点等形式进行标记，还可以是通过其他形式进行刻度标记，具体可以根据应用场景进行调整，此处不作限定。例如，如图11以及图12用虚线表示穿刺引导线，每两个圆点之间表示针穿刺方向上的距离为5毫米。此外，在进行平面外穿刺计算穿刺针针尖到穿刺目标的距离时，还要考虑穿刺针相对于探头的角度，在计算出的针尖坐标和针尾坐标，计算出针的引导线后，根据穿刺针和探头之间的角度计算出每个刻度值对应在超声平面的距离。例如刻度为5毫米，则表示在超声平面上的距离为5*cos(a)，a为穿刺针与超声平面的夹角。因此，本申请可以根据穿刺针的位置信息，生成穿刺针到穿刺目标的引导图像，使操作人员能够直观地获知穿刺针的穿刺引导路径，更准确地进行穿刺。
需要说明的是，引导图像中可以包括第一引导图、第二引导图、第三引导图以及第四引导图中的一种或多种，具体可以根据实际应用场景，此处并不作 限定。
在一个实施例中，除了当第四引导图为引导线时，在引导线上标记刻度外，还可以在超声图像中显示可穿刺的深度。如图13以及图14所示。可以直接在超声图像中显示可穿刺的深度。例如，图13以及图14中，显示当前可支持的最大穿刺深度为35毫米，当然，此处的35毫米仅仅是举例说明。
在一个实施例中，当穿刺针以不同的角度进行穿刺，或在穿刺中调整穿刺针的角度时，引导图像也可以根据穿刺针的穿刺角度进行调整。平面内穿刺的穿刺角度变化示意图如图15以及图16所示。当穿刺针的介入角度发生偏转时，计算穿刺针的偏转角度，并根据偏转角度重新获取穿刺针的针尖坐标以及针尾坐标，并计算穿刺针到穿刺目标的距离，根据穿刺针到穿刺目标的距离调整第四引导图中的刻度，若超声图像中包括穿刺深度显示信息，则可以更新穿刺深度显示信息。平面外穿刺时，如图17以及图18所示，若穿刺针角度偏转，具体的引导图更新方法与平面内穿刺类似，计算穿刺针的偏转角度，并根据偏转角度重新获取穿刺针的针尖坐标以及针尾坐标，并计算穿刺针到穿刺目标的距离，根据穿刺针到穿刺目标的距离调整第四引导图中的刻度，若超声图像中包括深度显示信息，则可以更新深度显示信息。更进一步地，穿刺针到穿刺目标的距离可以是穿刺针针尖到穿刺目标的距离。因此，在本申请实施例中，若穿刺针的穿刺角度发生偏转，可根据穿刺针的偏转角度，实时计算并更新穿刺针到穿刺目标的引导图以及显示距离，使操作人员可以直观地获知穿刺情况，进行更准确的穿刺。
在一个实施例中，在计算得到穿刺针针尖到穿刺目标的距离后，可以根据穿刺针针尖到穿刺目标的距离调整引导图像的显示状态变化。例如，可以根据穿刺针针尖到穿刺目标的距离调整引导图像的颜色变化，也可以根据穿刺针针尖到穿刺目标的距离变化调整显示的距离数值或引导线刻度值。具体例如，穿刺针针尖到穿刺目标的距离越近，引导图像的颜色越深，或穿刺针针尖到穿刺目标的距离越近，引导图像的颜色越明显等，或通过不同的颜色标识不同的距离，例如，绿色表示距离大于10毫米，黄色表示距离在5-10毫米之间，红色表示距离小于5毫米。因此，在本申请实施方式中，通过引导图像的显示状态变化，更能标识穿刺针针尖到穿刺目标的距离的变化，使操作人员可以直观地 获知穿刺针针尖到穿刺目标的距离，根据穿刺针针尖到穿刺目标的距离调整穿刺的角度或速度等，提高穿刺的准确性。
在一个实施例中，如图19所示，在进行平面外或平面内穿刺时，可能无法从超声图像中显示完整的穿刺针，仅能显示部分穿刺针或穿刺针的针尖。此时可以根据电磁导航技术得到穿刺针的位置信息，生成穿刺针相对于探头位置关系的穿刺指示图，该穿刺指示图指示穿刺针到超声图像所在平面的距离和/或穿刺角度。例如，该穿刺指示图可以是探头俯视投影图，其中，探头俯视投影图中包括穿刺针到超声图像的俯视投影平面的距离和/或穿刺角度。该穿刺指示图也可以是其他角度的投影图，此处不做限定。因此，在进行平面外或者平面内穿刺时，也可以根据探头俯视投影图获知穿刺针相对于探头100的位置以及穿刺角度，使操作人员可以更准确地进行穿刺。
一个实施例中，也可仅显示超声图像和上述穿刺指示图。本申请提供的另一超声成像方法包括：
通过探头向目标区域发射超声波，并接收所述目标区域返回的超声回波，以获得超声回波数据；
根据所述超声回波数据生成超声图像；
获取介入性物体相对于所述探头的位置关系；
根据所述介入性物体相对于所述探头的位置关系生成穿刺指示图，所述穿刺指示图指示所述介入性物体相对于所述超声图像所在平面的位置关系；
显示所述超声图像和所述穿刺指示图。
需要说明的是，生成超声图像和显示超声图像的方式可参考上述实施例进行理解，此处不再赘述。
该介入性物体可以是穿刺针，该穿刺指示图指示该介入性物体相对于该超声图像所在平面的位置关系包括：该穿刺指示图指示该穿刺针到该超声图像所在平面的距离和/或穿刺角度。该超声图像所在平面也可理解为探头阵元发射超声波的扫描平面。例如，该穿刺指示图可以是探头俯视投影图，其中，探头俯视投影图中包括穿刺针到超声图像的俯视投影平面的距离和/或穿刺角度。例如，对于面外穿刺，可实时显示穿刺针针尖到超声图像的俯视投影平面相交点的距离，和穿刺针与超声图像的俯视投影平面的倾斜角度；对于面内穿刺， 也可实时显示穿刺针在超声图像的俯视投影平面内穿刺的距离。例如以该超声图像的俯视投影平面为水平线为例，穿刺针沿该水平线的垂直方向介入表示面外穿刺，穿刺针沿该水平线的水平方向介入表示面内穿刺，此处仅作列举，不做具体限定。该穿刺指示图也可以是其他角度的投影图，此处不做限定。
一个实施例中，穿刺指示图还指示介入性物体到探头的距离和/或穿刺角度。例如该介入性物体可以是穿刺针，该穿刺指示图可以是探头俯视投影图，其中，探头俯视投影图中包括穿刺针到探头的距离和/或穿刺角度。例如，对于面外穿刺，可实时显示穿刺针针尖到探头俯视投影平面相交点的距离，和穿刺针与探头俯视投影平面的倾斜角度；对于面内穿刺，也可实时显示穿刺针相对于探头俯视投影平面的距离。例如以该探头俯视投影平面为矩形框为例，穿刺针沿该矩形框的垂直方向介入表示面外穿刺，穿刺针沿该矩形框的水平方向介入表示面内穿刺，此处仅作列举，不做具体限定。该穿刺指示图也可以是其他角度的投影图，此处不做限定。
在一个实施例中，当确定穿刺针针尖与穿刺目标的距离小于第一阈值时，可以控制第四引导图淡出、消失或转变为浅色等，以更清楚地显示针尖。例如，如图20所示，当进行面外穿刺时，若穿刺针针尖到穿刺目标的距离小于5毫米时，第四引导图逐渐消失或者立即消失，以更清楚地显示针尖。此外，第四引导图部分消失的情况如图21所示，当穿刺针到达穿刺目标，在穿刺目标的引导图403所处的范围内，不显示或淡化第四引导图404，但在穿刺目标以外，还可以继续显示第四引导图，以在更清楚地显示穿刺针针尖的同时，更准确地显示穿刺针的穿刺方向。当然，其他的引导图也可以立即消失、逐渐消失、淡化或调整尺寸等。例如，如图22所示，可以是调整第一引导图或第三引导图的尺寸或形状等，使第一引导图与第三引导图重合等，避免第一引导图引起对穿刺目标或穿刺针多余的覆盖。又例如，如图23所示，为更好地显示针尖的情况，也可以不显示或淡化第一引导图。因此，在本申请实施例中，当穿刺针针尖与穿刺目标的距离小于第一阈值时，可以控制第四引导图淡出、全部消失、部分消失或转变为浅色等，更清楚地显示针尖，使操作人员可以更清楚地获知针尖的位置，更清楚穿刺路径，提高穿刺准确性。
在一个实施例中，以图24为例，当穿刺针针尖到达穿刺目标后，继续沿 穿刺路径穿刺的距离超过第二阈值时，可以生成警示信息，以提示操作人员。例如，警示信息可以是“已到达穿刺目标！”、“请参考超声图像进行穿刺！”等，以对穿刺针的位置进行警示，防止操作人员穿刺过度或穿刺不足等，提高穿刺的准确性。
因此，在本申请实施例中，首先获取穿刺针的位置信息，并根据穿刺针的位置信息生成引导图像，根据引导图像对穿刺进行引导，实时预测穿刺针的穿刺路径，使操作人员清楚地获知穿刺针的穿刺路径，以及穿刺针到穿刺目标的穿刺引导，及时根据引导图像进行穿刺针的穿刺调整，及时调整穿刺手法、穿刺角度、穿刺方位等，保证穿刺针可以到达穿刺目标，进行更准确的穿刺。
