背景技术
当前，超声成像诊断已经成为非常重要的医疗诊断手段。随着超声成像技术的不断进步，超声设备朝着全触屏化、智能化方向发展，很多功能不再提供物理按钮，而使用触屏按钮；很多功能提供智能辅助，而不需要用户手工操作。这些使得对于不能熟练使用超声成像设备的新手来说，需要先学习超声成像设备的操作。尤其对于超声设备提供的众多扫查参数(例如，动态范围、谐波成像、空间复合等)，这些参数的物理意义对于一些非专业或经验较少的医生来说比较复杂，他们并不完全清楚这些参数的作用。通常，对于超声成像设备的教学主要是通过主动阅读产品使用手册、学习内置在超声成像设备中的教学组或预设参数、自动化识别图像特征进行提示等教学方法进行。但是，这些教学方法存在不够直观、交互性较差、教学效率较低的问题。
因此，希望提供一种医疗设备及系统以增强交互性、提高教学效率。

仅作为示例，当医疗设备为超声成像设备，运行教学任务的过程可以看作为执行教学任务脚本的过程。其中，如教学任务为图7所示的教学任务，则过程可以包括以下步骤：
S1-1，使用者登录系统，下载已经安装的教学任务脚本。
S1-2，用户点击PW模式切换按钮，系统发送这个点击事件，此时该教学任务脚本的接收事件节点被触发，将ClickEvent节点推入栈中，该ClickEvent节点输出引脚EventName被该系统事件设置成PW mode。
S1-3，从栈中取出ClickEvent节点，该ClickEvent节点没有输入数据，执行该节点逻辑(事实上事件接收节点没有额外的节点逻辑)。
S1-4，该ClickEvent节点有输出，将其逻辑输出节点DisplayVideo节点放入栈中，将其数据输出节点连接的isEqual节点放入栈中。
S1-5，栈中有两个未取出的节点，先取出栈顶的isEqual节点。
S1-6，isEqual节点有二个输入引脚，其中EventName已经由ClickEvent节点的输出赋值，所以将另外一个输入引脚string连接的节点——一个数学变量节点放入栈中。
S1-7，取出栈顶的数学变量节点，该节点没有输入数据，该节点也没有额外节点逻辑，输出是一个值为“PW mode”的字符串，将该字符串赋值给isEqual节点的string输入引脚，并将isEqual节点放入栈中。
S1-8，取出栈顶的isEqual节点。
S1-9，该节点的两个输入引脚现在均有赋值，则执行该节点逻辑，判断这两个输入引脚的值是否相等。这里是相等的，result输出引脚值是true。将该引脚相连的DisplayVideo节点放入栈中，而栈中之前已经存放了该节点，所以不重复放入。
S1-10，取出栈顶的DisplayVideo节点，该节点的一个数据输入引脚Condition已经有值，值为true，执行该节点逻辑。

S1-12，将DisplayVideo节点的逻辑输出连接的节点EndTask放入栈中，该节点是任务的终止节点，并且栈中现在没有其他节点，完成教学任务。
在一些实施例中，可以通过使用者账户在医疗设备中下载教学任务。以医疗设备是超声设备为例，下载教学任务的过程可以包括：使用者使用账户、密码向服务器请求登录；服务器通过认证后，查询使用者的教学任务列表和权限域内共享的教学任务列表，并发送给云端存储器；云端存储器查询教学任务列表，获得教学任务脚本和校验数据，并返回给服务器；服务器将获得的教学任务脚本和校验数据，加入排序信息返回给使用者所在的本地超声系统；本地超声系统首先会根据校验数据决定是否覆盖本地教学任务，并根据新手教学任务的排序信息将新手教学任务排序。之后，使用者可以根据当前需求选择合适的教学任务并激活，超声系统会解析教学任务脚本，在满足执行条件时依次运行相应的教学任务节点。
在一些实施例中，可以创建新的教学任务作为目标教学任务，或对候选教学任务中的至少一个进行编辑后作为目标教学任务。关于如何创建新的教学任务可以参见图5的相关描述，在此不再赘述。

仅作为示例，当医疗设备为全触屏的超声成像设备，医疗设备的教学方法可以包括以下步骤：
S2-1，使用者登录到超声成像设备后，超声成像设备自动向服务器请求使用者的教学任务数据列表，在得到列表数据后更新本地可使用的教学任务。此时列表数据可以包含使用者账户自己创建的，还可以包括权限域内其账户设置成共享的。在列表中可以看到已经激活的教学任务和未激活的教学任务。
S2-2，使用者查看是否有符合当前需求的教学任务。如果有，选择并激活该教学任务，该任务会在条件符合时执行。如果没有，用户点击界面的“新建教学任务”或“编辑教学任务”按钮进入教学任务的创建和编辑界面。
S2-3，对之前列表中已经选择的一个已有的教学任务进行编辑修改，或者，新建并命名一个教学任务，使用者选择如上操作后会进入到教学任务的可视化编辑界面。

S2-6，在ClickEvent事件节点的EventName引脚处点击，并长按拖动，引出一条线段到合适位置，结束触摸，弹出新建节点菜单，选择创建名称为isEqual的逻辑节点，并且连接了上个ClickEvent节点的EventName引脚。该逻辑节点的输入数据也自动命名为EventName类型。长按空白区域弹出新建节点菜单，创建一个变量节点，点击变量节点设置变量节点的输入数据值为“PW Mode”，将该节点输出引脚和逻辑节点的第二个输入引脚相连。当逻辑节点判断EventName字符串为“PW Mode”时，Result引脚会输出true，否则输出false。
S2-7，使用与步骤S2-4到S2-6中类似方法，创建一个名称为DisplayVideo的展示节点，将事件节点的逻辑输出引脚和展示节点的逻辑输入引脚相连，将展示节点属性设置成播放一个视频，播放视频条件为一个bool型变量，设置播放视频的内容，设置视频控件显示的位置等等。将之前的逻辑节点的Result输出引脚和视频展示节点的Condition输入引脚相连。最后连接一个名称为EndTask的结束节点结束教学任务。这个教学任务即：当用户触发了一个点击“PW Mode”按钮时，播放一个教学视频，并结束这个教学任务。
S2-8，编辑完整个教学任务后，点击保存并上传。系统将这个教学任务进行编译，如果编译通过则会自动启动上传，如果编译未通过会提示该教学任务哪个部分设置报错。完成编译后，系统就会将这个教学任务脚本上传到该使用者账号下的云服务器中。如果该任务设置成了域权限共享，那么上传后其他在 域权限内的账号即可查看和使用该教学任务。
S2-9，回到选择可用教学任务列表的界面，激活选中的教学任务。
在一些实施例中，可以通过使用者账户将教学任务保存到云端存储器中。以医疗设备是超声设备为例，保存教学任务的过程可以包括：使用者使用账户登录后，将需要保存的教学任务流脚本与排序所需数据上传到服务器；服务器通过认证后，生成教学任务脚本的校验数据，并将新手教学任务脚本和校验数据上传到云端存储器；云端存储器会根据校验数据决定是否覆盖使用者之前的教学任务脚本，并将处理结果返回给服务器；服务器会返回的处理结果决定是否更新教学任务列表，并将最终结果返回给本地超声系统；本地超声系统会根据返回的最终结果处理接下来的工作。如果存档成功，提示成功；如果存档失败，教学任务脚本将会保存在本地，并且等待下次保存时，重试上述步骤。
在一些实施例中，在运行目标教学任务的过程中，可以响应于与扫查协议相关联的多个初始参数中的目标参数被选择或调节，在显示界面上展示目标参数预调节前所对应的第一图像以及目标参数预调节后所对应的第二图像。在一些实施例中，关入如何对目标参数进行选择和调节以得到调节前后的图像的更多内容，可以参见图8的相关描述，在此不再赘述。
本说明书一些实施例中，通过响应于基于显示界面触发的指令展示候选教学任务，根据指令从候选教学任务选中并运行目标教学任务，从而可以通过可视化的方式直观地选择并运行教学任务，界面友好，使用简单，方便了新用户等的使用；通过基于可视化界面创建、编辑教学任务，进而运行教学任务，可以快速简便地创建教学任务，从而帮助用户更好地了解医疗设备(例如，超声设备等)，能够通过引导用户动手实践掌握医疗设备的各项使用功能及操作。

步骤510，基于创建区域获取创建指令，响应于创建指令展示节点菜单。
在一些实施例中，可以从创建区域获取触发的创建指令，响应于该创建指令展示节点菜单。例如，图6a所示为编辑界面的示意图，其中，创建区域可以为图6a中的区域620，展示的节点菜单可以为图6a中的菜单640。

在一些实施例中，对于全触屏超声设备，可以通过长按屏幕在对应位置调出节点创建菜单。
在一些实施例中，可以通过选中节点的一个引脚，滑动拉出一根连线，在另外一个节点的引脚处松开，即可和将两个节点相连。
在一些实施例中，可以通过选中节点的一个引脚，滑动拉出一根连线，在创建区域(例如，图6a中的区域620)空白处松开，则自动调出节点创建菜单。
在一些实施例中，可以判断节点间的数据和逻辑连接是否符合连接规则，若不符合则连接可以被取消并提示错误。连接规则可以根据需要设定，例如，数据可以由一个输出引脚流出，流入到多个节点的数据输入引脚，但一个节点的输入引脚只能由某一个节点的输出引脚流入。
在一些实施例中，节点可以在创建区域中随意改变(移动)位置，可以选中节点修改属性和删除节点。
在一些实施例中，超声应用节点可以包括多种类型的节点，例如，模式切换节点、测量包切换节点、探头模拟数据节点、图像参数设置节点、功能激活节点和B模式图像对比节点等中的至少一个。
模式切换节点可以触发模式切换，并且在传入相应模式参数后会更改超声机器的参数配置。
测量包切换节点可以切换测量包，使得用户在指定的测量包下进行操作。
探头模拟数据节点可以通过选择机器上保存的超声图像的原始数据作为教学任务的模拟数据。执行该模拟数据后，超声设备不再以连接探头的真实数据作为输入，而是以模拟数据作为输入。
图像参数设置节点可以通过设置该节点下的参数数据，使得医学成像设备的参数数据得以改变。
功能激活节点可以激活医疗设备的特定功能，例如，冻结、存图、查看患者、查看回放等。
B模式图像对比节点可以根据该节点的设置，对比某个特定输入参数的超声图像数据和参数，显示在某个设定区域内的模拟B模式超声图像。
仅作为示例，超声应用节点的节点控件与基础节点的节点控件类似，其外观特征可以如图6c所示。
在一些实施例中，节点菜单可以包括基础节点菜单和超声应用节点菜单等。其中，基础节点菜单中包括的节点类型为基础节点，超声应用节点菜单中包括的节点类型为超声应用节点。
在一些实施例中，可以从创建区域获取创建指令，响应于该创建指令展示基础节点菜单和超声应用节点菜单等。
步骤520，基于节点菜单获取节点选择指令，节点选择指令中包括被选中的教程节点的节点标识。
在一些实施例中，医疗设备响应于触发的创建指令展示节点菜单后，可以基于展示的节点菜单，对展示的节点菜单中的节点进行选择，从而触发节点选择指令。在一些实施例中，可以从展示的节点菜单获取节点选择指令，其中，获取的节点选择指令中包括被选中的教程节点的节点标识。
在一些实施例中，被选中的教程节点的节点标识可以包括被选中的教程节点的节点名称、节点ID等中的至少一个。其中，节点标识中的节点名称和节点菜单中的节点名称相对应。例如，被选中的教程节点名称为ClickEvent，则此处的节点名称为ClickEvent。
在一些实施例中，若节点菜单包括基础节点菜单和超声应用节点菜单，则节点选择指令可以包括第一选择指令和第二选择指令。在一些实施例中，可以从基础节点菜单获取第一节点选择指令，其中，第一节点选择指令中包括被选中的教程节点的基础节点标识。在一些实施例中，可以基于超声应用节点菜单获取第二节点选择指令，其中，第二节点选择指令包括被选中的教程节点的超声应用节点标识。
步骤530，基于创建区域对节点标识对应的教程节点进行配置，得到每个教程节点的配置信息。
在一些实施例中，获取被选中的教程节点的节点标识后，可以基于创建区域对该节点标识对应的教程节点进行配置，从而得到每个教程节点的配置信息。具体来说，可以通过对教程节点的节点属性和节点数据进行配置，从而完成教程节点的配置。
教程节点的配置信息是指与教程节点相关的信息，可以包括多种信息，例如，节点的类型信息、节点逻辑信息、节点设置信息、节点位置信息、节点逻辑引脚连接信息、节点数据引脚连接信息、教程脚本的脚本属性信息、教程脚本的配置信息等中的至少一种。在一些实施例中，配置信息中包括教程节点的节点属性和节点数据。其中，节点数据可以包括节点的逻辑信息、节点的逻辑引脚连接信息、节点的数据引脚连接信息等，节点属性可以包括节点的类型信息、节点的设置信息、节点的位置信息、教程脚本的脚本属性信息、教程脚本的配置信息等。
在一些实施例中，可以根据节点选择指令显示各教程节点的配置框。其中，被选中的教程节点的节点标识对应的教程节点对应地有配置框，配置框中包括有教程节点的配置信息。在一些实施例中，可以基于各教程节点的配置框，得到各教程节点的配置信息。具体来说，可以将在教程节点的配置框中选择的配置信息，确定为教程节点的配置信息。通过教程节点的配置框，能够使用户直观地看到并选择教程节点的配置信息，提高了获取教程节点的配置信息的准确度和便利性。
在一些实施例中，在对选中的教程节点的节点标识对应的教程节点进行配置时，可以从第一个节 点标识对应的节点开始，沿着逻辑引脚连线依次处理每个节点。首先，可以解析每个节点的内部逻辑和设置信息；然后，检查其输入数据引脚连接信息，如果该引脚被连接，则沿着输入连接线逆向查找前置节点的输出数据引脚连接信息，直到所有前置数据均满足要求，从而得到每个节点标识对应的目标教程节点的配置信息。
步骤540，根据教程节点和教程节点的配置信息，创建候选教学任务。
在一些实施例中，可以基于编辑界面创建候选教学任务，其中，边界界面还包括信息提示区域。在一些实施例中，可以基于编辑界面和/或信息提示区域获取设置指令，其中，设置指令包括对教程节点的节点数据和节点属性等进行设置的信息。例如，新建的教程节点1类型为逻辑节点，名称为isEqual；新建的教程节点2类型为数学变量节点，输入数据值为“PW Mode”。
在一些实施例中，响应于设置指令对各教程节点的节点数据和节点属性进行设置。例如，响应于设置指令中教程节点的节点数据和节点属性信息，将教程节点1类型设置为逻辑节点，名称设置为isEqual；教程节点2类型设置为数学变量节点，输入数据值设置为“PW Mode”。
在一些实施例中，可以基于述教程节点和各教程节点的配置信息生成候选教学任务对应的教学任务脚本。
在一些实施例中，可以将各教程节点作为候选教学任务包括的教程节点，将各教程节点的配置信息作为候选教学任务包括的教程节点间的逻辑关系，从而得到候选教学任务。在一些实施例中，可以根据得到的候选教学任务的教程节点和配置信息等生成该教学任务对应的教学任务脚本。
在一些实施例中，可以对生成的教学任务脚本进行编译检查。在一些实施例中，如果编译检查被通过，则可以上传教学任务脚本；如果编译检查未被通过，则可以提示教学任务脚本的设置错误位置。
在一些实施例中，可以将生成的教学任务脚本上传到各种本地或网络平台，例如，云平台等。
本说明书一些实施例中，通过编辑界面包括的创建区域获取创建指令，并响应于该创建指令展示节点菜单，从而可以使用户通过直观展示的节点菜单自主选择教程节点；通过节点菜单获取包括节点标识的节点选择指令，可以基于创建区域对节点标识对应的教程节点进行准确地配置；通过选中的教程节点和对应的配置信息，快速准确地创建出教学任务，降低了创建教学任务的复杂性，提高了创建效率。
图8是根据本说明书一些实施例所示的医疗设备辅助方法的示例性流程图。如图8所示，流程800包括下述步骤。在一些实施例中，流程800可以由处理设备140执行。在一些实施例中，流程800可以包括在步骤440的运行目标教学任务的过程中。
步骤810，获取扫查协议。在一些实施例中，步骤810可以由获取模块310执行。
在一些实施例中，扫查协议可以是医疗设备中用于实际扫查的程序。在一些实施例中，扫查协议可以仅与即将调用的参数和/或图像相关，而不用于实际扫查。例如，用户在利用医疗设备(例如，医疗设备110)对被扫查对象进行扫查时，可以根据被扫查对象的信息选择或设置相应的扫查协议。处理设备140可以接收该扫查协议，并根据该扫查协议控制医疗设备对被扫查对象进行扫查成像。又例如，用户可以在终端设备(例如，终端设备130)上选择扫查协议，用户可以选择或设置与扫查协议相关的参数，以在终端设备的显示设备上展示参数预调节前后对应的图像。
在一些实施例中，医疗设备可以包括超声设备、CT设备、MRI设备、PET设备、SPECT设备等，或其任意组合。扫查协议可以与一个或以上初始参数相关联。不同的医疗设备可以对应不同的初始参数。为了便于描述，本说明书中将以超声设备作为医疗设备的示例进行说明，其并不限制本申请的范围。在一些实施例中，超声设备可以包括一维超声设备、二维超声设备和/或三维超声设备。在一些实施例中，医疗设备可以为手持式超声设备。
在一些实施例中，扫查协议可以包括探头种类、扫查模式等中的至少一种。例如，探头可以包括线阵探头、相控阵探头、4D探头、腔内探头、经食道探头、胃镜探头等。扫查模式可以包括M扫查模式、PW扫查模式、与扫查对象一一对应的扫查模式等。用户可以通过选择探头、扫查模式等进入扫查页面。
在一些实施例中，扫查协议可以与医疗设备的辅助功能中所要展示的图像中的对象相关。具体地，在一些实施例中，当扫查协议中包括的探头种类是针对某个部位的探头时，若针对该扫查协议调用医疗设备的辅助功能，则展示的图像中的对象即为该部位。例如，若扫查协议中包括的探头是经食道探头，则医疗设备的辅助功能中展示的扫描对象为心脏。在一些实施例中，当扫查协议中包括的扫查模式是针对某个部位的扫查模式时，若针对该扫查协议调用医疗设备的辅助功能，则展示的图像中的对象即为该部位。例如，若扫查协议中包括的扫查模式是应用于腹部、心脏、甲状腺等的扫查模式，则医疗设备的辅助功能中展示的扫描对象分别对应为腹部、心脏、甲状腺等。
在一些实施例中，与超声设备的扫查协议相关的初始参数可以与超声设备和/或超声图像相关。在一些实施例中，初始参数可以包括动态范围、深度、发射功率、增益、伪彩、线密度、斑点噪声抑制、时间增益补偿(time gain compensation，TGC)、谐波成像、多波束成像、空间复合、亮度、焦点调节等，或 其任意组合。在一些实施例中，初始参数可以包括多级或多类初始参数。例如，可以根据临床应用中各个初始参数的使用频次(即，用户在进行图像优化时调节各个初始参数的频次)，将初始参数划分为多级初始参数。又例如，可以根据各个初始参数对图像的调节效果划分为多级初始参数。例如，动态范围、亮度、增益等参数可以划分为一级初始参数，其与参数可以划分为另一级初始参数。每个初始参数可以对应多个数值，以供用户对其进行调节来优化图像。在一些实施例中，初始参数可以是连续数值化的参数。例如，连续数值化的参数可以包括深度、增益、亮度等。在一些实施例中，初始参数可以是进行分档的参数。例如，对于“斑点噪声抑制”参数，可以用强度、去噪指数对其进行量化分档。
步骤820，接收辅助功能触发指令。在一些实施例中，步骤820可以由接收模块320执行。
用户可以通过向处理设备140发送辅助功能触发指令来触发医疗设备的辅助功能，以了解医疗设备的各个参数(或初始参数)对图像的应用效果。在一些实施例中，辅助功能触发指令可以包括静态辅助功能触发指令和动态辅助功能触发指令。
在本说明书中，静态辅助功能触发指令与医疗设备的静态辅助功能相关。医疗设备的静态辅助功能可以与预存数据库相关。预存数据库可以包括各个初始参数的各个值对应的图像。在一些实施例中，预存数据库还可以包括多个组合参数的各个组合值对应的图像。组合参数，即两个或以上初始参数的组合。用户触发静态辅助功能指令后，处理设备140可以基于所选择的目标参数(例如，用户想要了解的参数及其值)，通过查询预存数据库来显示与目标参数相对应的图像。换句话说，处理设备140不是实时根据目标参数计算得到所要展示的图像，而是通过调用对应的预存图像来进行展示。在一些实施例中，医疗设备的静态辅助功能可以直接加载在医疗设备上，以供用户在未进行扫查时或在扫查过程中进行调用。在一些实施例中，医疗设备的静态辅助功能也可以以应用程序(Application，APP)、网页等形式加载在终端设备上以方便用户随时随地调用。
动态辅助功能触发指令与医疗设备的动态辅助功能相关。医疗设备的动态辅助功能可以与实时采集的图像相关。处理设备140可以基于实时采集的图像和/或所选择的目标参数通过实时计算得到所要展示的图像。因此，医疗设备的动态辅助功能需要加载在医疗设备上，以通过医疗设备实时采集图像。
在一些实施例中，用户可以通过物理按键、触摸屏幕、鼠标、语音、手势、眼动、脑电波等方式向处理设备140发送辅助功能触发指令。例如，医疗设备上可以设置有辅助功能触发按钮，用户可以通过点击该按钮向处理设备140发送辅助功能触发指令。又例如，用户界面上设置有辅助功能触发模块，用户可以通过鼠标选择或触摸屏幕触发该模块以向处理设备140发送辅助功能触发指令。再例如，用户可以通过预设触发规则(例如，快速双击、长按某个参数按钮)，以向处理设备140发送辅助功能触发指令。例如，在一些实施例中，当超声设备正在进行扫查时，用户可以通过快速双击或长按“动态范围”参数按钮来触发与动态范围对应的辅助功能，即向处理设备140发送与动态范围对应的辅助功能触发指令。换句话说，通过快速双击或长按“动态范围”参数按钮，可以进入动态范围的辅助功能界面，以进一步供用户在该辅助功能界面设置动态范围的预调节值。
在一些实施例中，处理设备140对扫查协议和辅助功能触发指令的获取可以不存在先后顺序。换句话说，处理设备140可以先获取扫查协议，再获取辅助功能触发指令；也可以先获取辅助功能触发指令，再获取扫查协议。在一些实施例中，处理设备可以同时获取扫查协议和辅助功能触发指令。例如，当医疗设备的静态辅助功能以APP的形式加载在终端设备上时，APP上可以设置有同时出发特定扫查协议和辅助功能触发指令的按钮，当用户点击该按钮后，可以直接进入与扫查协议相关静态辅助功能界面。
步骤830，接收多个初始参数中被选择的目标参数。在一些实施例中，步骤830可以由接收模块320执行。
在一些实施例中，可以基于扫查协议或辅助功能触发指令，在显示界面上展示多个初始参数。
在一些实施例中，当接收到扫查协议时，处理设备140即可以在显示界面显示与扫查协议相关联的初始参数。例如，对于以APP形式加载在终端设备上的静态辅助功能，当用户打开APP并选择扫查协议后，终端设备的显示设备上即可显示与扫查协议相关的初始参数，以供用户进行选择学习。又例如，对于在医疗设备上加载的动态辅助功能，当用户选择或设置扫查协议后，医疗设备的显示设备(或显示界面)上即可显示与扫查协议相关的初始参数。在一些实施例中，处理设备140可以响应于接收到辅助功能触发指令，显示初始参数。例如，当处理设备140获取到扫查协议后，响应于用户触发了辅助功能，可以在医疗设备的显示设备上展示与扫查协议相关的初始参数。
在一些实施例中，当初始参数包括多级/多类初始参数时，处理设备140可以在显示界面上分别展示各级/各类初始参数。例如，当初始参数包括初级参数(例如，使用频次较高的参数)和高级参数(例如，使用频次较低的参数)时，处理设备140可以基于扫查协议或辅助功能触发指令，在显示界面上展示初级参数。进一步地，响应于显示高级参数的显示触发指令(例如，用户可以选择显示界面上显示的“高级”按钮)，处理设备140可以在显示界面上展示高级参数。再例如，当初始参数包括第一类初始参数、第二 类初始参数时，处理设备140可以基于扫查协议或辅助功能触发指令，展示各类初始参数的类别。进一步地，响应于显示特定类别的显示触发指令(例如，第一类初始参数显示触发指令)，处理设备140可以在显示界面上展示该类别对应的初始参数。
在一些实施例中，当在显示界面上展示多个初始参数后，用户可以基于展示的多个初始参数选择目标参数。
在一些实施例中，当医疗设备的辅助功能被加载在医疗设备上时，可以不展示初始参数。具体地，当处理设备140接收扫查协议和辅助功能触发指令后，可以不在显示界面上展示初始参数，此时，用户可以通过设置在医疗设备上的各个参数按钮来对初始参数进行选择和/或设置，以确定目标参数。
在一些实施例中，响应于用户选择目标参数，处理设备140可以接收多个初始参数中被选择的目标参数。目标参数包括所选择的初始参数的种类即其对应的预调节值。
在一些实施例中，用户可以选择显示界面上展示的一个或多个初始参数作为目标参数。也就是说，用户可以对初始参数进行单选或多选。例如，在显示界面上可以罗列多个初始参数，每个参数前设置有选择框，用户可以选中(例如，单击、双击)想要了解参数前的选择框。进一步地，在选择完毕后，用户可以通过确认操作(例如，点击“应用”按钮)以确定选择的一个或多个选择框对应的参数作为目标参数。在一些实施例中，可以将特定的几个初始参数组合形成一个新参数，并将这几个参数的不同值的组合设置成新参数的不同档位，以达到对图像的不同调节效果。例如，如图10所示，可以将动态范围、TGC、增益组合形成一个新参数“图像优化”。可以将动态范围、TGC、增益的参数值针对调节穿透性能、分辨率，设置成不同的组合，以对应“图像优化”的不同档位(例如，穿透1档、穿透2档、穿透3档、分辨率1档、分辨率2档、分辨率3档等)。用户可以通过点击“图像优化”按钮并设置其对应的档位来实现同时选择动态范围、TGC、增益的组合值。在一些实施例中，用户可以通过物理按键、触摸屏幕、鼠标、语音、手势、眼动、脑电波等方式来选择目标参数。当目标参数被选择后，用户可以进一步对目标参数的预调节值进行选择或设置。例如，用户可以选择几档的“深度”、设置增益的数值等。
步骤840，在显示界面上展示目标参数预调节前所对应的第一图像以及目标参数预调节后所对应的第二图像。在一些实施例中，步骤350可以由显示模块230执行。通过在显示界面上展示预调节前后的图像，可以让用户更为直观地了解目标参数的对图像的应用效果。
预调节是指基于目标参数确定感兴趣图像的过程。需要知道的是，处理设备140并没有在扫查过程中对参数进行实际调节，而只是通过调用或计算等方式得到并展示感兴趣图像(例如，目标参数预调节前后对应的第一图像、第二图像)。用户可以通过预览感兴趣图像再确定是否对该目标参数进行调节来优化采集图像。
在一些实施例中，第一图像和/或第二图像可以包括静态图像(例如，图像帧)或动态图像。在本申请中，动态图像可以指由多个连续的静态图像所构成的图像。在一些实施例中，动态图像可以以图形交换格式(Graphics Interchange Format，GIF)、动态图像专家组(Moving Picture Experts Group，MPEG)格式、MP4、音频视频交错格式(Audio Video Interleaved，AVI)等格式进行存储或处理。例如，当与扫查协议关联的对象为心脏时，由于心脏时刻在跳动，第一图像和第二图像可以为动态图像以更好地展示心脏状态。又例如，当与扫查协议关联的对象为血管时(例如，血管彩超)，第一图像和第二图像可以为动态图像以更好地了解血流情况。
在一些实施例中，当辅助功能触发指令为静态辅助功能触发指令时，第一图像和第二图像可以基于目标参数通过查询预存数据库进行确定。例如，每个目标参数(例如，每个初始参数或多个初始参数的组合的类别)可以对应一个初始图像(可以为静态图像，也可以为动态图像)。处理设备140或其他处理设备可以基于初始图像和目标参数(例如，预调节值)，确定该目标参数对应的目标图像(可以为静态图像，也可以为动态图像)。处理设备140或其他处理设备可以将每个目标参数对应的初始图像和目标图像存储在预存数据库中。当用户选择目标参数(包括初始参数的总类及其对应的预调节值)后，处理设备140可以从预存数据库中调取目标参数对应的初始图像作为第一图像，以及目标参数对应的目标图像作为第二图像。在一些实施例中，每个目标参数(或组合目标参数)可以为医疗设备辅助系统100的默认设置。
在一些实施例中，当辅助功能触发指令为动态辅助功能触发指令时，处理设备140可以基于扫查协议采集初始图像，并在显示界面上展示该初始图像。当接收到被选择的目标参数后，处理设备140可以将采集的初始图像作为第一图像。处理设备140可以基于目标参数(例如，初始参数的预调节值)，处理初始图像来确定第二图像。处理设备140可以在显示界面上展示确定的第一图像和第二图像。在一些实施例中，第一图像和第二图像可以随着用户移动探头而实时变化。例如，当用户触发动态辅助功能后，用户可以使用探头实时采集对象(例如，模体)的图像，此时，医疗设备的显示设备上可以实时显示左右两幅相同的初始图像(例如，动态图像)。进一步地，用户可以选择目标参数(例如，动态范围)，此时，显示设备上可以在左方展示初始图像(即，第一图像)，右方展示基于目标参数和初始图像确定的第二图像。
在一些实施例中，当两个或以上目标参数被选择时，处理设备140可以在显示界面上同时展示多个目标参数预调节前对应的初始图像、每个目标参数预调节后对应的图像、以及至少两个目标参数对初始图像共同作用时对应的图像。例如，目标参数可以包括第一目标参数和第二目标参数，处理设备140可以首先确定第一目标参数和第二目标参数预调节前对应的初始图像。处理设备140可以基于初始图像和第一目标参数，确定第一目标参数预调节后对应的第一子图像。处理设备140还可以基于初始图像和第二目标参数，确定第二目标参数预调节后对应的第二子图像。处理设备140还可以基于初始图像、第一目标参数和第二目标参数，确定第一目标参数和第二目标参数预调节后对应的第三子图像。处理设备140可以在显示界面上展示初始图像、第一子图像、第二子图像和第三子图像。具体地，当辅助功能触发指令为动态辅助功能触发指令时，第一目标参数和第二目标参数预调节前对应的初始图像可以为当前采集的图像。当辅助功能触发指令为静态辅助功能触发指令时，第一目标参数和第二目标参数预调节前对应的初始图像可以预存数据库中预存的第一目标参数和第二目标参数的参数种类所对应的图像。
在一些实施例中，在医疗设备进行实时扫查的过程中，基于当前采集图像，若用户想了解某个参数(例如，新设置的医疗设备的参数)对当前采集图像的应用效果(例如，优化效果)，可以触发医疗设备的辅助功能，并设置想要了解的该参数的参数值，此时，医疗设备的显示设备上可以同时显示当前采集图像(即，第一图像)和该参数预调节后的第二图像。进一步地，若用户满意该参数对当前采集图像的优化效果，用户可以接受对该参数的调节。例如，用户可以点击显示界面上的“应用”按钮，此时，显示界面上可以只显示该参数调节过后对应的图像。
在一些实施例中，处理设备140还可以在显示界面上展示关于目标参数的描述(例如，物理意义、功能描述等)，以辅助用户进行理解(如图9中930、图10中1030、图11中1130所示)。在一些实施例中，为便于用户观察目标参数预调节前后的变化，处理设备140还可以在第一图像和/或第二图像上进行标注。例如，处理设备140可以将第一图像和第二图像进行对比。处理设备140可以根据对比结果，在第一图像和/或第二图像上用标记符号(例如，如图9中915和925所示)标出图像信号差异高于阈值的地方。具体地，例如，针对超声设备中的“动态范围”参数，处理设备140可以在第二图像中用“○”圈出变亮或变暗程度最大的地方。进一步地，还可以在第一图像的相同位置用“○”进行标记。再例如，针对将“深度”参数值调小时，处理设备140可以在第一图像中标记出相对于第二图像多出的结构。处理设备140还可以在标记的旁边用文字进行说明。
本说明书一些实施例中，通过将各个参数预调节前后对应的图像同时展示给用户，大大节省了用户了解各个参数的时间；通过以APP的形式安装在移动终端的静态辅助功能，方便用户随时随地了解想要学习的参数，提高用户体验；通过展示参数预调节前后的图像，用户可以先通过预览该参数预调节前后的效果，再决定是否对该参数进行调节，使用户更灵活地运用各个参数。
应当注意的是，上述有关流程400、500、800的描述仅仅是为了示例和说明，而不限定本说明书的适用范围。对于本领域技术人员来说，在本说明书的指导下可以对流程400、500、800进行各种修正和改变。然而，这些修正和改变仍在本说明书的范围之内。例如，步骤810和步骤820的顺序可以交换。
图9是根据本说明书一些实施例所示的超声设备的静态辅助功能中针对单个目标参数所对应的至少部分显示界面的示意图。如图9所示，目标参数为动态范围。当用户触发静态辅助功能时，显示界面900可以显示动态范围预调节前(例如，动态范围值为30)所对应的第一图像910及动态范围预调节后(例如，动态范围值为60)所对应的第二图像920。第一图像910和第二图像920均为静态图像。在一些实施例中，显示界面900的下方还可以显示关于动态范围的参数信息930。参数信息930可以包括动态范围的参数物理意义、动态范围的参数功能效果等。在一些实施例中，可以在第一图像910和第二图像920上标注出第一图像910和第二图像920之间差异较大的地方。例如，圆圈925对应的部分(即肝脏)的边界相较于圆圈915对应的部分的边界更清晰。通过显示界面900上展示的动态范围预调节前后的图像(图像910和920)，可以使用户(例如，医生)更为直观地了解动态范围这个参数对图像的应用效果，大大节省了医生的时间。
图10是根据本说明书一些实施例所示的超声设备的静态辅助功能中针对组合目标参数所对应的至少部分显示界面的示意图。如图10所示，组合目标参数为“图像优化”参数，包括动态范围、增益和TGC。当用户触发静态辅助功能时，显示界面1000可以显示“图像优化”预调节前所对应的第一图像1010及“图像优化”预调节后所对应的第二图像1020。第一图像1010和第二图像1020均为静态图像。在一些实施例中，显示界面1000的下方还可以显示关于“图像优化”的参数信息1030。在一些实施例中，可以在第一图像1010和第二图像1020上标注出第一图像1010和第二图像1020之间差异较大的地方(例如，圆圈1015和1025所示的部分)。通过展示的“图像优化”预调节前后的图像，可以使用户更为直观地了解“图像优化”对图像的应用效果，大大节省了医生的时间。
图11是根据本说明书一些实施例所示的超声设备的动态辅助功能中针对单个目标参数所对应的 至少部分显示界面的示意图。动态辅助功能中针对单个目标参数所对应的显示界面1100可以与图9中所示的静态辅助功能中针对单个目标参数所对应的显示界面900相似。区别在于动态辅助功能中显示的图像为动态图像。如图1100所示，目标参数为动态范围。当用户触发动态辅助功能时，显示界面1100可以显示动态范围预调节前所对应的第一图像1110及动态范围预调节后所对应的第二图像1120。第一图像1110和第二图像1120均为动态图像。第一图像1110和第二图像1120可以根据用户移动探头而实时变化。在一些实施例中，显示界面1100的下方还可以显示关于动态范围的参数信息1130。在一些实施例中，可以在第一图像1110和第二图像1120上标注出第一图像1110和第二图像1120之间差异较大的地方(例如，圆圈1115和1125所示的部分)。通过展示的动态范围预调节前后的图像，可以使用户更为直观地了解动态范围参数对动态图像的应用效果，大大节省了医生的时间。
图12是根据本说明书一些实施例所示的超声设备的B模式下调节深度值的教学任务的示意图。
如图12所示的教学任务可以模拟B模式环境下的参数调节。通过查看模拟探头数据显示的超声图像，手动调节B模式的深度参数到一定的范围，并呈现调节前后的图像。其中，第一图像可以为调节前的图像，第二图像可以为调节后的图像。在该范围下呈现的图像质量明显优于未调节前的图像，即第二图像的质量明显优于第一图像的质量。这使得使用者能够通过动手实践学习到超声机器中如何调节深度参数使得图像达到想要的效果。
图12中所示的教学任务设定为接收到一个系统点击事件(即ClickEvent节点)后触发，该事件如果是切换B模式的事件，则激活模拟的B模式。
如图12所示，该B模式切换节点(即ActiveBMode节点)可以接收三个输入数据。其中，Condition作为该节点逻辑运行的触发条件，ProbeData作为该模式的模拟探头数据，BModeParams作为该模式参数数据。使用设定好的模拟探头数据后，系统将不再以真实探头数据作为输入。例如，该模拟数据是一个多帧肾脏超声数据，由于肾脏位于腹部深处，所以需要将depth参数调整到合适范围才能看到肾脏图像。图像参数设置节点(即BModeParams节点)将改变当前超声系统下的参数设置情况。如图12所示，可以将Depth参数设置成5，其他依然使用系统当前参数值。在上述参数设置的基础上，当前的模拟环境情况下产生的图像中看不到完整的肾脏。
激活到模拟环境下的B模式后，可以接着通过文本显示节点(即DisplayText节点)显示一串文字提示。例如，“调节Depth参数可以改变B模式下可见深度距离。想要看见更深的组织情况，调大参数；想要看到更大浅层组织图像，调小参数。现在请调节Depth参数，使整个肾脏组织清晰可见。”
上述提示可以一直显示在界面上，并且进入逻辑等待节点(即WaitForEvent节点)，等待用户进行参数调整。
当系统发出参数调整事件(例如，通过用户手动操作、自动调整等)时，可以触发参数调整事件节点(即ParamChangeEvent节点)。该节点的输出是系统发出事件时带的两个数据，一个是参数名ParamName，另一个是参数值ParamValue。这两个参数值可以经过几个逻辑计算节点。在经过这些逻辑计算节点的的逻辑运算后，当判断用户将Depth参数调整到15以上时，可以将true的condition输出到逻辑等待节点。
当逻辑等待节点收到condition输入数据为true时，可以继续执行下面的B模式图像比较节点(即BModeImageCompare节点)。
BModeImageCompare节点可以根据该节点的设置，对比某个特定输入参数的超声图像数据和参数，即对比实时图像与在某个设定区域内的图像。在一些实施例中，该对比模式可以是双幅图像模式。例如，左边一幅图像为实时图像(即第一图像)和实时参数，而右边一幅图像是上述设定的超声图像数据(即第二图像)和参数。用户退出对比模式后，可以进入结束节点(即EndTask节点)。
结束节点可以提示用户完成了B模式下Depth参数引导，可以在界面上进行文字等提示。例如，显示“恭喜你将Depth参数调整到了正确范围，现在可以看到完整的肾脏了，您已完成本次教学！”。并且在用户确认后退出该模拟的B模式环境，回到真实的系统环境下。
本说明书实施例可能带来的有益效果包括但不限于：(1)通过响应于基于可视化界面触发的指令展示候选教学任务，根据指令从候选教学任务选中并运行目标教学任务，从而可以通过可视化的方式直观地选择并运行教学任务，界面友好，使用简单，方便了新用户等的使用；(2)通过基于可视化界面创建、编辑教学任务，进而运行教学任务，可以快速简便地创建教学任务，从而帮助用户更好地了解医疗设备(例如，超声设备等)，能够通过引导用户动手实践掌握医疗设备的各项使用功能及操作；(3)通过可视化界面获取各种指令，从而创建、编辑教程节点，快速准确地创建出教学任务，降低了创建教学任务的复杂性，提高了创建效率；(4)通过将各个参数预调节前后对应的图像同时展示给用户，并通过各种静态和动态辅助功能，节省了用户了解各个参数的时间，提高用户体验，使用户能够直观地了解各个参数的意义以及调节效果，从而方便用户更快、更有效地掌握医疗设备的功能和操作。需要说明的是，不同实施例可能产生 的有益效果不同，在不同的实施例里，可能产生的有益效果可以是以上任意一种或几种的组合，也可以是其他任何可能获得的有益效果。

同时，本说明书使用了特定词语来描述本说明书的实施例。如“一个实施例”、“一实施例”、和/或“一些实施例”意指与本说明书至少一个实施例相关的某一特征、结构或特点。因此，应强调并注意的是，本说明书中在不同位置两次或多次提及的“一实施例”或“一个实施例”或“一个替代性实施例”并不一定是指同一实施例。此外，本说明书的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
此外，除非权利要求中明确说明，本说明书所述处理元素和序列的顺序、数字字母的使用、或其他名称的使用，并非用于限定本说明书流程和方法的顺序。尽管上述披露中通过各种示例讨论了一些目前认为有用的发明实施例，但应当理解的是，该类细节仅起到说明的目的，附加的权利要求并不仅限于披露的实施例，相反，权利要求旨在覆盖所有符合本说明书实施例实质和范围的修正和等价组合。例如，虽然以上所描述的系统组件可以通过硬件设备实现，但是也可以只通过软件的解决方案得以实现，如在现有的服务器或移动设备上安装所描述的系统。
同理，应当注意的是，为了简化本说明书披露的表述，从而帮助对一个或多个发明实施例的理解，前文对本说明书实施例的描述中，有时会将多种特征归并至一个实施例、附图或对其的描述中。但是，这种披露方法并不意味着本说明书对象所需要的特征比权利要求中提及的特征多。实际上，实施例的特征要少于上述披露的单个实施例的全部特征。
一些实施例中使用了描述成分、属性数量的数字，应当理解的是，此类用于实施例描述的数字，在一些示例中使用了修饰词“大约”、“近似”或“大体上”来修饰。除非另外说明，“大约”、“近似”或“大体上”表明所述数字允许有±20％的变化。相应地，在一些实施例中，说明书和权利要求中使用的数值参数均为近似值，该近似值根据个别实施例所需特点可以发生改变。在一些实施例中，数值参数应考虑规定的有效数位并采用一般位数保留的方法。尽管本说明书一些实施例中用于确认其范围广度的数值域和参数为近似值，在具体实施例中，此类数值的设定在可行范围内尽可能精确。
针对本说明书引用的每个专利、专利申请、专利申请公开物和其他材料，如文章、书籍、说明书、出版物、文档等，特此将其全部内容并入本说明书作为参考。与本说明书内容不一致或产生冲突的申请历史文件除外，对本说明书权利要求最广范围有限制的文件(当前或之后附加于本说明书中的)也除外。需要说明的是，如果本说明书附属材料中的描述、定义、和/或术语的使用与本说明书所述内容有不一致或冲突的地方，以本说明书的描述、定义和/或术语的使用为准。
