Description

一种超声探头以及控制超声诊断仪的方法和装置
本申请要求于2017年12月29日提交中国专利局、申请号为201711478367.4、发明名称为“一种超声探头以及控制超声诊断仪的方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及超声影像技术领域，特别是涉及一种超声探头以及控制超声诊断仪的方法和装置。
背景技术
随着医用超声诊断设备在日常医疗中的广泛应用，超声影像技术已经成为临床诊断检查中必不可少的手段之一，与X射线成像技术，电子计算机断层扫描(Computed Tomography，CT)成像技术，磁共振成像(Magnetic Resonance Imaging，MRI)技术被公认为四大现代医学的影像技术。超声诊断仪利用超声影像技术，检测人体不同组织、病理组织与正常组织之间声学差异，已广泛应用到心脏、腹部、妇产科、外周血管、各种小器官、骨骼等全身检查，是医院不可或缺的检测设备。
超声诊断仪通常会配备触摸屏、面板按键或遥控器以便医生控制实现各功能操作。一般情况下，医生需要一边拿着超声探头进行超声图像采集操作，一边点击触摸屏或按键来控制超声诊断仪。例如，医生通过点击“深度”、“焦点”、“增益”和“对比度”等按键调节成像参数以获得更好的超声图像，点击“冻结”和“存储”等按键实现基础控制功能。
但是，在某些应用场合下由于超声探头与操作面板有着一定的距离，操作起来较不方便。例如，在临床穿刺实施中，医生距离超声设备的主机距离较远，无法操控主机，在这种情况下，往往需要两个人配合进行操作，一人操作超声探头采集图像信息，另一人点击操作面板。这样不仅增加了操作难度，容易出错，而且不便于随时调节图像，大大降低了灵活性。
现有技术中，最为普遍的解决方法是在超声探头的外壳上设置若干个按键，向医生提供一些使用过程中的常用功能。
带按键的超声探头需要在结构上进行改进才能配置按键，不仅会影响密封效果，还会影响整体美观。而且，经过频繁按压以后，按键的表面及按键与外壳相接的位置很可能出现微小的裂缝，进而导致液体的渗入，影响外壳内的换能器和电路板的正常工作，使得超声探头损坏，严重降低超声探头的使用寿命。此外，在进行超声诊断时，医生往往需要调节很多成像参数来获取最佳的图像效果，例如，增益、深度、焦点位置和频率等等，而超声探头上往往只有2～4个按键可以使用，无法满足医生调节需求。
可见，如何实现对超声诊断仪的灵活控制，是本领域技术人员亟待解决的问题。

在实际应用中，可以将超声诊断仪的开始按键或者是某一个特定的按键作为毫米波收发器11发射毫米波信号的触发按键。当触发按键被用户按下后，超声诊断仪可以向超声探头发射用于检测用户手势的指令，当超声探头中内置的处理器12接收到该指令后，可以控制毫米波收发器11发射毫米波信号。
超声探头中内置的处理器12和超声诊断仪的主机可以通过电缆线连接，用于实现超声探头和超声诊断仪之间的信息交互。当超声探头的处理器12获取到用户手势对应的第一控制命令后，可以向超声诊断仪发送所述第一控制命令，以实现对所述超声诊断仪的控制。
由上述技术方案可以看出，超声探头中的毫米波收发器，可以发射和接收毫米波信号；超声探头中的处理器，可以依据所述毫米波信号进行手势识别，并根据所述手势对超声诊断仪进行相应控制。用户仅需在距离超声探头的一定范围内做出简单的手势动作后，就可以轻易实现对超声诊断仪的控制，而无需触碰操作面板的按键，满足了临床的无菌要求，极大地提高了操作超声诊断仪的灵活性和工作效率。
本发明实施例提供了一种控制超声诊断仪的方法，应用于超声探头，所述方法包括：采用毫米波信号进行手势识别，根据所述手势对所述超声诊断仪进行相应控制。
接下来将对超声探头根据毫米波信号进行手势识别的具体过程展开介绍，如图2所示，该过程包括：
S201：当接收到用于检测用户手势的指令后，发射第一毫米波信号，并接收所述第一毫米波信号经由所述用户手势反射回来的第二毫米波信号。
S202：依据所述第一毫米波信号和所述第二毫米波信号，获取所述用户手势的运动速度和位置信息。
为了便于对接收到的第二毫米波信号进行后续的分析处理，需要对接收到的第二毫米波信号进行预设采样处理，获取采样信号。
其中，该预设采样处理包括对第二毫米波信号进行放大、滤波处理，并利用模数转换器对放大、滤波后的信号进行采样，获取到采样信号。
在本发明实施例中可以利用第一毫米波信号和采样信号的时间差和多普勒频移，计算出用户手势的运动速度和位置信息。
在具体实现中，可以通过比较第一毫米波信号与采样信号的多普勒频移，确定出用户手势的运动速度；计算发射所述第一毫米波信号和接收到所述采样信号的时间差，并依据所述时间差确定出用户手势的位置信息。
用户手势的运动速度可以用于表示超声诊断仪相应参数的调节速度。用户手势的位置信息可以包含不用时刻用户手指与超声探头之间的距离，依据用户手势的位置信息可以确定出用户手指的变化情况，即确定出用户做出的是何种手势动作。
S203：依据所述运动速度和所述位置信息，确定出用户手势信息。
手势信息可以用于表示用户所做的手势动作。在本发明实施例中，需要将获取的用户手势的运动速度和位置信息，转化成处理器可识别的手势信息，以便于后续查找该手势动作对应的控制命令。
S204：获取所述用户手势信息对应的控制命令，并向超声诊断仪发送所述控制命令，实现对所述超声诊断仪的控制。
每一个有效的手势动作对应着唯一的一个控制命令。控制命令可以表示对超声诊断仪进行何种具体的控制。
在本发明实施例中，预先存储有手势信息和控制命令的对应关系。其 中，手势信息和控制命令的对应关系可以以列表的形式存储。
通过查找该对应关系，可以获取到用户手势信息对应的控制命令。
例如，手势信息为食指在空中以顺时针方向划圈，其对应的控制命令为提高图像增益，并且第一手势信息中包含的用户手势的运动速度表示图像增益的调节速度。
通过向超声诊断仪发送控制命令，实现对所述超声诊断仪的控制。
由上述技术方案可以看出，超声探头接收到用于检测用户手势的指令后，发射第一毫米波信号，并接收所述第一毫米波信号经由用户手势反射回来的第二毫米波信号；依据第一毫米波信号和接收到的第二毫米波信号，获取所述用户手势的运动速度和位置信息；依据所述运动速度和所述位置信息，确定出用户手势信息，并获取与所述用户手势信息对应的控制命令；向超声诊断仪发送所述控制命令，实现对所述超声诊断仪的控制。用户仅需在距离超声探头的一定范围内做出简单的手势动作后，就可以轻易实现对超声诊断仪的控制，而无需触碰操作面板的按键，满足了临床的无菌要求，极大地提高了操作超声诊断仪的灵活性和工作效率。
考虑到在实际应用中，超声探头利用内置的毫米波收发器发射第一毫米波信号时，该第一毫米波信号的扫描范围有限，当用户在扫描范围之外做出用户手势时，毫米波收发器将无法接收到第一毫米波信号经由用户手势反射回来的第二毫米波信号。故此，在本发明实施例中，可以增加相应的判断步骤，具体的，可以判断预设时间内是否接收到所述第二毫米波信号；当在预设时间内未接收到第二毫米波信号时，则进行报警提示。
通过报警提示，可以及时提醒用户，其手势动作不在第一毫米波信号的扫描范围之内，以便于用户及时调整其手指所在的位置。
