Description

一种支持多探头同步扫描的超声诊断设备及方法 技术领域
本发明涉及医疗设备领域，尤其涉及一种支持多探头同步扫描的超声诊断设备及方法。
背景技术
探头是超声诊断设备中重要的部件。负责将电信号转换为声信号，发射到人体内；再将人体组织反射回来的声信号转换为电信号，传输到超声诊断设备中的信号处理环节，用于成像。
随着现代科技发展，超声诊断技术日趋完善。超声诊断设备在临床领域得到广泛使用，各种不同工作频率、不同外形的探头也投入到临床应用中。
针对不同诊断部位的深度、形状、结构，探头被设计成不同工作频率，不同外形，以匹配相应的诊断部位。医生在诊断过程中只能手持一个探头，同一时刻只能对病人的一个部位进行扫描，因此，要完成对一个病人不同身体部位的完整超声诊断，医生时常要切换探头，例如先使用相控阵探头扫描心脏，在切换探头，使用线阵探头扫描外周血管。
传统的超声诊断设备，可通过多个插槽连接多个探头（一个插槽连接一个探头），但同一时刻只能激活一个探头，即一个探头进行扫描成像。因此，当医生需要用不同探头扫描不同部位的图像时，必须顺次切换工作探头，依次得到不同部位的图像数据。
目前，针对不同切面的同步扫描，仅能通过双平面探头来实现。双平面探头拥有两个声头（见图1的声头A和声头B），分别对不同切面进行同步扫描。如经直肠的前列腺检查，可同时进行纵切面与横切面的同步扫描。由于是一个探头的两个声头，所以能进行同步扫描的不同切面相距很近，无法满足临床更广泛的需求。
欧洲专利0528693A1，提出了一种支持多个探头连接在一个插槽上的超声诊断设备，使得该超声诊断设备可以同时连接数目超过系统插槽数的探头。该专利公开的技术方案中，超声诊断系统由主机、连接器，和若干探头组成。其中连接器为一对插头、插槽，连接探头和主机。其中探头结构包含有第一级连接器、第二级连接器。第一级连接器与主机或另一个探头相联；第二级连接器通过互联电缆连接第一级连接器，连接另外一个探头的连接器，还可以连接从互联电缆（连接第一、第二级连接器）分支出来的探头。
该专利公开的超声诊断设备，一个插槽可连接多个探头。当探头数目大于主机插槽数时，也可以使所有探头同时与主机连接，从而不需要在使用过程中去插拔、替换插槽上的探头。
现有专利技术的应用范围有限，并存在如下一些缺陷：
双平面探头，拥有两个声头，分别对不同切面进行同步扫描。但是由于是一个探头的两个声头，所以能进行同步扫描的不同切面相距很近，无法满足临床更广泛的需求。
欧洲专利0528693A1公开的超声诊断设备，支持多个探头连接在一个插槽上，可以同时连接数目超过系统插槽数的探头。但是，该超声诊断设备只能使系统同时连接多个探头，并不支持多探头同时工作、同步扫描，无法满足医生对人体不同部位同时诊断的需求。
 发明内容
为了消除现有技术的上述缺陷，本发明提出了一种支持多探头同步扫描的超声诊断设备及方法，其可以在同一时刻支持多个探头同时独立工作，使超声诊断设备同时得到不同探头各自的扫描图像数据，满足对人体不同部位同时诊断的需求。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
以下将结合图2～图7，说明本发明实施例提供的一种支持多探头同步扫描的超声诊断设备的具体实现。
参见图2，本发明实施例提供的一种支持多探头同步扫描的超声诊断设备包含有显示模块1、成像系统3、多个探头（如图所示的探头A、探头B、探头C、探头D等等），该设备还可以包括操作面板2以及插槽（图示中以多个为例，实际实现中可以为一个或多个），多个探头连接在插槽上；多个探头贴合在被诊断者体表的不同部位，通过多个探头对被诊断者体表的不同部位进行同步实时扫描；多个探头扫描得到回波信号后将其传送给成像系统3；优选的实施方式中，探头的数量大于等于插槽的数量。需要说明的是，插槽数量较少，例如为一个时，可以通过转接头与多个探头连接。
在具体实现中，探头是直接紧密贴合在被诊断者体表的固定位置上，以对被测对象固定位置处的同一切面进行扫描。如此，可以保证每次扫描都是同一切面，使获得的超声图像更加准确，避免了连续扫描带来的声功率风险以及现有技术中经食道探头的不舒适感。
成像系统3用于将多个探头传送回来的多个回波信号转换成多个超声图像；
显示模块1耦接于成像系统3上，接收成像系统3输出的经处理后的多个超声图像并同步显示。
需要说明的是，显示模块1具体实现中，可以是台式、便携、手提等各种超声设备中的显示装置/模块。
具体的，操作面板2用于接收触发信号；显示模块1包括多个显示窗口，多个显示窗口用于在操作面板的触发下实时同步显示成像系统根据多个回波信号在所选择的成像模式上获得的多个超声图像。
具体参见图3，当有探头A和探头B两个探头同时扫描时，显示窗口相应有两个，分别为探头A图像窗口，探头B图像窗口；当有探头A、探头B、探头C、探头D四个探头同时扫描时，显示窗口相应有四个，分别为探头A图像窗口，探头B图像窗口，探头C图像窗口，探头D图像窗口；依次类推，当有n个探头同时扫描时，显示窗口相应的就有n个。
为了使得本发明提供的超声诊断设备的多个探头同步扫描，本发明的超声诊断设备中还设置有探头高压开关。
其中，该探头高压开关的数量与插槽数量相同，用于控制多个探头在扫描脉冲重复时间间隙内切换，以预定的扫描时序对被诊断者体表的不同部位进行交替扫描。
另外，每个探头包括多个阵元（如图4所示的，探头A包括阵元1、2、3……N……N），如果探头的阵元数量大于插槽（即物理通道）数量，则探头中进一步包括阵元高压开关，该阵元高压开关用于控制其所在探头的各个阵元对该探头对应的体表部位进行交替扫描。
其中，探头高压开关和阵元高压开关由控制电路控制。如图5所示，探头高压开关和阵元高压开关由控制电路4控制。当探头高压开关在控制电路4的控制下切换到探头A的接点b，使得探头B与物理通道联通时，探头B工作；同理，当阵元高压开关在控制电路4的控制下切换到探头A的阵元A1的接点a1，使得探头A的阵元A1与探头A联通时，探头A的阵元A1工作；当阵元高压开关在控制电路4的控制下切换到探头A的阵元A2的接点a2，使得探头A的阵元A2与探头A联通时，探头A的阵元A2工作；
需要说明的是：不管是探头高压开关还是阵元高压开关，其切换时间数量级为微秒，完全可以在探头正常扫描脉冲重复时间间隙内完成切换。这与常规的探头切换不同，常规切换探头使用继电器，切换时间太长。
为了支持探头在正常扫描脉冲重复时间间隙内完成切换，本发明提供两种扫描时序，如下：
第一种预定的扫描时序为：多个探头以扫描线为单位，依次交替扫描被诊断者体表的不同部位。
具体的，多个探头的第一个探头首先扫描其对应的体表部位的第一条扫描线之后，由第二个探头扫描其对应的体表部位的第一条扫描线，直至多个探头中的最后一个探头扫描得到其对应的体表部位的第一条扫描线后，再由多个探头的第一个探头首先扫描其对应的体表部位的第二条扫描线；依次循环直至多个探头扫描得到其对应的体表部位的完整一帧图像。
第二种预定的扫描时序为：多个探头以帧为单位，依次交替扫描被诊断者体表的不同部位。
具体为：多个探头的第一个探头首先扫描其对应的体表部位的一帧图像之后，由第二个探头扫描其对应的体表部位的一帧图像，依次循环直至多个探头中的最后一个探头扫描得到其对应的体表部位的一帧图像。
以下以两个探头（探头A和探头B）为例，结合图6进行说明。其中，探头A贴合在被诊断者体表的A部位，探头B贴合在被诊断者体表的B部位。
第一种扫描时序：探头A扫描A部位的第一扫描线，探头B扫描B部位的第一扫描线，探头A扫描A部位的第二扫描线，探头B扫描B部位的第二扫描线……依次交替扫描，直至探头A得到A部位所有的扫描线组成一帧关于A部位的扫描图像，探头B得到B部位所有的扫描线组成一帧关于B部位的扫描图像。依次循环，直至探头A得到A部位的多帧扫描图像，探头B得到B部位的多帧扫描图像。
第二种扫描时序：探头A扫描A部位得到一帧图像，紧接着探头B扫描B部位得到一帧图像；探头A再依次扫描一帧，紧接着探头B再依次扫描一帧……依次循环，直至探头A得到A部位的多帧扫描图像，探头B得到B部位的多帧扫描图像。
另外，本发明中的探头高压开关和阵元高压开关可以对多探头扫描时序进行调整，以支持多探头不同模式的同步扫描成像。各探头可自由选择使用成像模式为如下的至少一种：B型（Brightness，辉度）成像模式、M型（Motion，一维空间多点运动时序图）成像模式、彩色成像模式、脉冲波（PW）成像模式、弹性成像模式、3D（三维）成像模式及4D（四维）成像模式。
以探头A选择B成像模式，探头B选择M成像模式为例，其扫描时序见图7所示。
相应的，成像系统将多个探头传送回来的多个回波信号转换成多个超声图像为：
将多个回波信号进行数字处理以获得数字处理环节信号，根据数字处理环节信号及所选择的成像模式获得多个超声图像；成像系统所支持的成像模式为如下的至少一种：B型（Brightness，辉度）成像模式、M型（Motion，一维空间多点运动时序图）成像模式、彩色成像模式、脉冲波（PW）成像模式、弹性成像模式、3D（三维）成像模式及4D（四维）成像模式。
本发明还提供一种超声诊断方法，其在如前所述的超声诊断设备中实现，参见图8，为一种超声诊断方法实施例一的流程图，其包括如下步骤：
步骤100，通过多个探头对被诊断者体表的不同部位进行同步实时扫描并得到回波信号后将其传送给成像系统；
步骤101，通过成像系统将多个探头传送回来的多个回波信号转换成多个超声图像；
步骤102，通过显示模块接收成像系统输出的经处理后的多个超声图像并同步显示。
参见图9，为本发明提供的一种超声诊断方法实施例二的流程示意图。

步骤202，通过成像系统将多个探头传送回来的多个回波信号转换成多个超声图像；

其中，步骤200中预定的扫描时序为：多个探头以扫描线为单位，依次交替扫描被诊断者体表的不同部位。或者，预定的扫描时序为：多个探头以帧为单位，依次交替扫描被诊断者体表的不同部位。
参见图10，为本发明提供的一种超声诊断方法实施例三的流程示意图。
本实施例三包括以下步骤：
步骤300，通过多个探头高压开关控制多个探头在扫描脉冲重复时间间隙内切换，以预定的扫描时序对被诊断者体表的不同部位进行交替扫描。
步骤301，通过设置在探头中的阵元高压开关控制其所在探头的各个阵元对该探头对应的体表部位进行交替扫描。
具体实现中，通过控制电路控制探头高压开关和阵元高压开关的开断。

上述实施例一至实施例三中，通过成像系统将多个探头传送回来的多个回波信号转换成多个超声图像，包括：
通过成像系统将多个回波信号进行数字处理以获得数字处理环节信号，根据数字处理环节信号及所选择的成像模式获得多个超声图像；成像系统所支持的成像模式为如下的至少一种： B型成像模式、M型成像模式、彩色成像模式、脉冲波成像模式、弹性成像模式、3D成像模式及4D成像模式。
其中，更进一步的细节可以参考对附图2至附图7的说明，在此不进行赘述。
本发明的实施例中，超声诊断设备上设置有多个插槽，该多个插槽连接有多个探头，该探头可以同步实时扫描，便于对被测者的多个部位同时进行超声扫描监测；
本发明实施例中所采用的探头，可以长时间贴合于病人体表，保证每次扫描都是同一切面，使获得的超声图像更加准确，避免了连续扫描带来的声功率风险。
可以理解的是，本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于一计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体（Read-Only Memory，ROM）或随机存储记忆体（Random Access Memory，RAM）等。本文所称的耦接，包括可以传递信号/能量的各种接触式和非接触式连接方式。本文虽然定义了监护主机，但可以理解的是，也可以通过超声主机和集成到超声主机的监护功能模块来实现相似的目的，还可以是超声功能模块和监护功能模块一同集成到其他医疗设备或系统中，比如将超声功能模块和监护功能模块集成到CT、MRI设备中。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
