Description

图像配准方法及装置 技术领域
本申请涉及医疗技术领域,具体涉及一种图像配准方法及装置。
背景技术
图像配准是将两幅图像进行空间匹配的过程,若要将图像A配准到图像B,则是将B作为参考图像,A作为浮动图像,得到图像A配准到图像B的变形场。医学影像配准技术是医学影像处理的基础,在图像信息融合、辅助诊断、手术规划以及医学基础理论研究等领域发挥着十分重要的作用。
将两幅图像进行手动配准有多种方式,操作者可以根据自己的喜好进行选择。在一种图像显示方式中,将两幅图像叠加显示,通过调节滑动条调节图像透明度以增强显示某一幅图像,例如,以电子计算机断层扫描(Computed Tomography,CT)图像和锥形束电子计算机断层扫描(Cone beam Computed Tomography,CBCT)图像配准为例,当滑动条调到最左边时,显示CT图像(CBCT图像完全透明),当滑动条调到最右边时,显示CBCT图像(CT图像完全透明)。
在该显示方式下进行图像配置时,操作者需要不断拖动滑动条(调节透明度,从0%到100%或者从100%到0%),观察两幅图像是否对齐,如果没有对齐,则手动调整图像,然后再重复上述过程,直到两幅图像完全对齐。
技术问题
由上可知,相关技术中图像显示方式下的图像配准,操作者调节透明度与调整图像位置需要分开进行,图像配准时间长,图像配准效率较低。

首先,本申请实施例中提供一种图像配准方法,包括:获取目标对象待配准的第一医学图像和第二医学图像;根据所述第一医学图像和所述第二医学图像输出第一目标观察影像至显示装置,以在所述显示装置交替显示所述第一医学图像和所述第二医学图像;根据所述第一目标观察影像,对所述目标对象进行图像配准。
如图2所示,为本申请实施例中图像配准方法的一个实施例流程示意图,该图像配准方法包括:
201、获取目标对象待配准的第一医学图像和第二医学图像。
202、根据所述第一医学图像和所述第二医学图像输出第一目标观察影像至显示装置,以在所述显示装置交替显示所述第一医学图像和所述第二医学图像。
203、根据所述第一目标观察影像,对所述目标对象进行图像配准。
本实施例中通过获取目标对象待配准的第一医学图像和第二医学图像;根据所述第一医学图像和所述第二医学图像输出第一目标观察影像至显示装置,以在所述显示装置交替显示所述第一医学图像和所述第二医学图像;根据所述第一目标观察影像,对所述目标对象进行图像配准。本申请中通过输出交替显示第一医学图像和第二医学图像的第一目标观察影像至显示装置,由于在第一医学图像和第二医学图像的交替显示过程中,操作者可以同步手动调整图像位置,节约了图像调整的时间,另外,第一医学图像和第二医学图像的交替显示,使得操作者很容易观察到第一医学图像和第二医学图像是否对齐,不需要反复调节透明度,节省了图像配准的时间,提高了图像配准的效率。
其中,步骤201中,目标对象可以是人体的某一个组织或器官,例如头颅,或肺部、肝部等器官,第一医学图像和第二医学图像均为目标对象的医学图像,即同一个组织或器官的医学图像,例如均为用户脑部的医学图像。
具体的,第一医学图像和第二医学图像从维度上来说,均可以是二维图像或三维图像,从图像类型上来说,均可以是CBCT图像,CT图像,超声图像(B超图像或彩超图像),核磁共振图像等,具体此处不作限定。另外,第一医学 图像和第二医学图像可以是同类型的医学图像,例如第一医学图像和第二医学图像均为CBCT图像,第一医学图像和第二医学图像也可以是不同类型图像,例如第一医学图像为CBCT图像,第二医学图像为CT图像等,具体此处不作限定。
第一医学图像和第二医学图像均可以是实时由图像采集设备的,也可以是第一医学图像和第二医学图像其中一张由图像采集设备采集,另一张为目标对象的历史医学图像,当然,也可以是两张均为历史医学图像,具体可以根据实际场景使用,此处不作限定。
另外,图像配准中,一般会将一张图像作为参考图像,另一张作为浮动图像,也称一个主图像,一个位次图像,本申请实施例中,第一医学图像可以是主图像,也可以是次图像,与之对应的,第二医学图像也可以是主图像或次图像,具体此处不作限定。
步骤202中,第一目标观察影像可以是第一医学图像和第二医学图像交替输出的影像,也可以是第一医学图像和第二医学图像合成的动态图像,此时,步骤202中根据所述第一医学图像和所述第二医学图像输出第一目标观察影像至显示装置也有多种实现方式,下面举例进行说明。
(1)第一目标观察影像可以是第一医学图像和第二医学图像交替输出的影像。
此时所述根据所述第一医学图像和第二医学图像输出第一目标观察影像至显示装置,包括:获取预先设置的图像输出时间间隔;按照所述图像输出时间间隔,将所述第一医学图像和第二医学图像依次作为第一目标观察影像,输出至所述显示装置。
将第一医学图像和第二医学图像交替输出的第一目标观察影像输出至显示装置中相应界面进行显示,第一医学图像和第二医学图像按图像输出时间间隔交互显示,操作者可以一边观察显示的交替图像一边调整第一医学图像和/或第二医学图像的位置(调节和显示几乎是实时的),直到第一医学图像和第二医学图像完全对齐。相比现有图像配准方式,本申请实施例在交替图像进行切换的过程中,操作者可以同步手动调整图像位置,节约了图像调整的时间, 另外,操作者很容易观察到第一医学图像和第二医学图像是否对齐,不需反复调节透明度,节省了图像配准的时间,提高了图像配准的效率。
其中,图像输出时间间隔为第一医学图像和第二医学图像之间进行切换输出的时间间隔,图像输出时间间隔可以根据需要预先设定,间隔时间可以是0.25秒、0.5秒或1秒等,未设定也可以是默认值,例如默认值为0.25秒等。
在本申请设置图像输出时间间隔的一种实施方式中,可以在显示装置的图像配准界面设置一“自动切换”按钮,例如可以设置在调整医学图像透明度的滑动条之后,在触发“自动切换”按钮时,显示下拉列表,下拉列表中显示了可供选择的图像输出间隔时间的多个选项0.25秒、0.5秒或1秒等,例如,操作者选中间隔时间后,就会在图像配准界面内开始显示该图像输出间隔下的第一目标观察影像。
在另一种方式中,可以在显示装置的图像配准界面设置一“自动切换”勾选框,勾选后,即可在图像配准界面内开始显示第一目标观察影像。图像输出时间间隔可以是默认值,也可以通过“切换时间”调节进度条、“切换时间设置”按钮等方式进行设置,需要说明的,本申请实施例中,设置图像输出时间间隔的界面显示方式可以多种多样,不做限定。
(2)第一目标观察影像为动态图像
其中,第一目标观察影像可以是目前已存在的动态图像格式,例如GIF图像,也可以是未来新出现的动态图像格式,此处只需要是动态图像即可,具体不作限定
此时,如图3所示,步骤202中所述根据所述第一医学图像和第二医学图像输出第一目标观察影像至显示装置,可以进一步包括:
301、获取预先设置的第一目标观察影像的图像帧数。
302、基于所述图像帧数,确定生成所述第一目标观察影像需要的第一医学图像的第一数量和第二医学图像的第二数量。
303、根据所述第一数量的第一医学图像数量和第二数量的第二医学图像,合成所述第一目标观察影像。
将生成的动态图像(第一目标观察影像)输出至显示装置中相应界面进行 显示,第一医学图像和第二医学图像按预设时间间隔交互显示,操作者可以一边观察显示的动态图像一边调整第一医学图像和/或第二医学图像的位置(调节和显示几乎是实时的),直到第一医学图像和第二医学图像完全对齐。相比现有方式,本申请技术方案在动态图像显示的过程中,操作者可以同步手动调整图像位置,节约了图像调整的时间,另外,通过本方案操作者很容易观察到主图像和次图像是否对齐,不需反复调节透明度,节省了图像配准的时间,提高了图像配准的效率。
同样的,在一种实施方式中,可以在显示装置的图像配准界面设置一“自动切换”按钮,例如可以设置在调整医学图像透明度的滑动条之后,在触发“自动切换”按钮时,显示下拉列表,下拉列表中显示了可供选择的图像输出间隔时间的多个选项0.25秒、0.5秒或1秒等,例如,操作者选中间隔时间后,就会在图像配准界面内开始显示该图像输出间隔下的动态图像。
在另一种方式中,可以在显示装置的图像配准界面设置“自动切换”勾选框,勾选后,即可在图像配准界面内开始显示动态图像。图像输出时间间隔可以是默认值,也可以通过“切换时间”调节进度条、“切换时间设置”按钮等方式进行设置。需要说明的,本申请实施例中,设置图像输出时间间隔的界面显示方式可以多种多样,不做限定。
在本申请一些实施方式中,所述根据所述第一数量的第一医学图像数量和第二数量的第二医学图像,合成所述第一目标观察影像,包括:将所述第一数量的第一医学图像数量和第二数量的第二医学图像,按照预设的数量间隔策略,合成所述第一目标观察影像。
其中,所述第一数量和所述第二数量可以相同也可以不同,当所述第一数量和所述第二数量相同时,所述根据所述第一数量的第一医学图像数量和第二数量的第二医学图像,合成所述第一目标观察影像,可以包括:将所述第一数量的第一医学图像数量和第二数量的第二医学图像,按照等间距方式,间隔合成所述第一目标观察影像。
其中,本申请实施例中描述的间距可以是两张第一医学图像之间的间距,也可以是两张第二医学图像之间的间距,具体可以根据实际使用场景设置,不 作限定。
具体的,例如第一目标观察影像121212,1代表第一医学图像,2代表第二医学图像,第一医学图像和第二医学图像按照等间距1的方式间隔合成第一目标观察影像,第一目标观察影像是由三张第一医学影像和三张第二医学影像合成的动态图像。又例如第一目标观察影像11221122,表示第一医学图像和第二医学图像按照等间距2的方式间隔合成第一目标观察影像。
由于第一医学图像一个为主图像,一个为次图像,主图像作为参考图像不作变动,因此次图像在动态图像中的帧数可以多一些,因此,在本申请另一些实施方式中,所述第一医学图像为主图像时,所述第二数量大于所述第一数量,可以有效观察作为浮动图像的次图像。
在一个实施方式中,当所述第二数量大于所述第一数量时,所述将所述第一数量的第一医学图像数量和第二数量的第二医学图像,按照预设的数量间隔策略,合成所述第一目标观察影像,可以包括:将所述第一数量的第一医学图像数量和第二数量的第二医学图像,按照间距递增方式,合成所述第一目标观察影像。
具体的,所述将所述第一数量的第一医学图像数量和第二数量的第二医学图像,按照间距递增方式,合成所述第一目标观察影像,包括:基于预设的第一初始间距以及预设间距公比,按照间距等比递增的方式,确定与每张第一医学图像数量对应的多张第二医学图像;根据每张第一医学图像及其对应的多张第二医学图像配对,依次合成所述第一目标观察影像。
例如,第一目标观察影像12122122221,其中,两张第一医学图像之间的初始间距为1,即一张第二医学图像,两张第一医学图像之间的间距依次为1,2,4,呈等比递增。
在另一个实施方式中,所述将所述第一数量的第一医学图像数量和第二数量的第二医学图像,按照间距递增方式,合成所述第一目标观察影像,包括:基于预设的第二初始间距以及预设间距公差,按照间距等差递增方式,确定与每张第一医学图像数量对应的多张第二医学图像;根据每张第一医学图像及其对应的多张第二医学图像配对,依次合成所述第一目标观察影像。
例如,第一目标观察影像1212212221,其中,两张第一医学图像之间的初始间距为1,即一张第二医学图像,两张第一医学图像之间的间距依次为1,2,3,呈等差递增。
对动态图像来说,其也有一个帧率,即每秒显示图像帧数,例如目标观察图像由6张图像合成(3张第一医学图像和3张第二医学图像),帧率为2帧/s,即目标观察图像可以动态显示3s(后续循环显示),每秒显示一张第一医学图像和一张第二医学图像。
本申请实施例中,第一目标观察影像的合成帧率可以是预先设置的帧率,例如所述第一目标观察影像的帧率为第一帧率,后续可以根据需要对合成帧率进行调整,具体的,所述根据所述第一目标观察影像,对所述目标对象进行图像配准,可以包括:获取用户调整第一目标观察影像帧率的帧率调整指令;根据所述帧率调整指令,将第一目标观察影像帧率调整为第二帧率,输出帧率调整后的第一目标观察影像;基于所述帧率调整后的第一目标观察影像,对所述目标对象进行图像配准。
例如,第二帧率为3帧/秒,将第一目标观察影像帧率调整由第一帧率调整为第二帧率,即第一目标观察影像的图像帧的数量相同,但是帧率可以由2帧/s调整为3帧/秒。
在本申请一些实施方式中,在图像配准过程中,可以对图像进行位置调整配准,具体的,如图4所示,所述根据所述第一目标观察影像,对所述目标对象进行图像配准,可以包括:
401、获取针对第一医学图像和/或第二医学图像的位置调整指令。
其中调整配准指令中可以包括第一医学图像调整的位置信息,例如,向左调整第一距离,例如1mm。其中,该位置调整指令可以是针对第一医学图像的位置调整指令,也可以是针对第二医学图像的位置调整指令,还可以是该位置调整指令包括两个位置调整信息,一个是针对第一医学图像的位置调整信息(用于调整第一医学图像的位置),一个是针对第二医学图像的位置调整信息,具体此处不作限定。
402、根据所述位置调整指令,输出位置调整后的第一目标观察影像。
403、基于所述位置调整后的第一目标观察影像,对所述目标对象进行图像配准。
本实施例中可以实时对医学图像的位置进行调整,生成实时的位置调整后的第一目标观察影像,便于后续继续进行配准。
在本申请一些实施方式中,在图像配准过程中,当医学图像不符合要求时,还可以采集新的医学图像,替换之前的医学图像进行重新配准,例如当需要更换第一医学图像时,具体的,所述图像配准方法还包括:获取针对第一医学图像的更换指令;基于所述更换指令,获取所述目标对象的第六医学图像,所述第六医学图像与所述第一医学图像为同一类型的医学图像;根据所述第六医学图像和所述第二医学图像输出第四目标观察影像至显示装置,以在所述显示装置交替显示所述第二医学图像和所述第六医学图像;基于所述第四目标观察影像,对所述目标对象进行图像配准。其中,所述第六医学图像为替换第二医学图像进行图像配准的图像。
在本申请一些实施例中,还可以将图像配准中各个调整过程中的目标观察影像保存下来,便于后续出现医疗纠纷或者其他需要回溯配准影像的场景中使用。
具体的,在本申请一些实施方式中,所述图像配准方法还可以包括:在每次获取针对第一医学图像或第二医学图像的位置调整指令之后,采集当前位置调整指令的时间信息;保存所述时间信息对应的目标观察影像,以形成不同时间的目标观察影像集合。即每次配准时的调整时,都保存当前配准时的目标观察影像,最终在完成配准后,形成时间的目标观察影像集合,方便后续回溯查看配准记录。
进一步的,所述图像配准方法还可以包括回溯的步骤,具体的,该图像配准方法还可以包括:获取针对所述目标对象的配准历史回溯指令,所述配准历史回溯指令包括回溯时间信息;获取所述目标观察影像集合中所述回溯时间信息对应的回溯目标观察影像;将回溯目标观察影像输出到所述显示装置进行显示。具体的,在显示装置的图像配准界面,可以显示回溯控件,用户点击回溯控件后,可以显示回溯时间输入框或者选择框,确定回溯时间,用户确定好回 溯时间后,即生成配准历史回溯指令,基于回溯时间信息,可以在上述实施例中保存的所述目标观察影像集合中的获取回溯目标观察影像。
另外,本申请实施例中,还可以输出一套或多套目标观察影像至显示装置,在显示装置的图像配准界面可以设置一个或多个显示窗口,显示这多套目标观察影像。
当显示装置的图像配准界面包括第一显示窗口时,所述根据所述第一医学图像和所述第二医学图像输出第二目标观察影像至显示装置,以在所述显示装置交替显示所述第一医学图像和所述第二医学图像,包括:根据所述第一医学图像和所述第二医学图像输出第二目标观察影像至显示装置,以在所述显示装置的第一显示窗口交替显示所述第一医学图像和所述第二医学图像。即在显示装置的第一显示窗口交替显示第一医学图像和所述第二医学图像。
显示装置的图像配准界面还可以包括第二显示窗口,第一显示窗口和第二显示窗口不同,第一显示窗口和第二显示窗口可以上下并列或者左右并列,第一显示窗口和第二显示窗口的尺寸可以相同,也可以不同,具体可以根据实际应用场景进行设置。
需要说明的是,本申请实施例中,显示装置的图像配准界面包括多个显示窗口时,多个显示窗口显示的图像有多种实现方式,下面举例进行说明:
1、多个显示窗口显示的两套目标观察影像具有同样的医学图像
具体的,基于第一医学图像与第二医学图像,第一医学图像与第三医学图像输出的两个目标观察影像,都以第一医学图像为参考基准。
此时,在一个具体实施例中,所述图像配准方法还包括:
(1)获取目标对象待配准的第三医学图像。
其中,所述第三医学图像为与所述第一医学图像为不同类型的医学图像或者同一类型不同时间拍摄的医学图像。
本实施例中,第一医学图像可以是参考医学图像(或主图像),第二医学图像和第三医学图像可以是浮动图像(或次图像)。此时,两套目标观察影像采用的同样的参考医学图像,方便相互印证。
(2)根据所述第三医学图像和所述第一医学图像输出第二目标观察影像 至显示装置,以在所述显示装置的第二显示窗口交替显示所述第三医学图像和所述第一医学图像。
其中,所述第一显示窗口和第二显示窗口为所述显示装置同一显示界面的两个不同的显示窗口。
(3)根据所述第一目标观察影像和所述第二目标观察影像,对所述目标对象进行图像配准。
本实施例中,第一医学图像分别与两个不同的医学图像:第二医学图像、第三医学图像结合输出第一目标观察影像和第二目标观察影像至显示装置的两个不同的显示窗口,两个显示窗口可以形成两个动态的配准画面,便于用户进行参考。
2、多个显示窗口显示的两套目标观察影像没有共同显示的医学图像,是两个维度的参考
具体的,基于第一医学图像与第二医学图像,第四医学图像和第五医学图像输出的两个目标观察影像,其中,所述第四医学图像为与所述第五医学图像为不同类型的医学图像或者同一类型不同时间拍摄的医学图像,且所述第四医学图像、所述第五医学图像、第一医学图像和第二医学图像均不相同。
此时,所述图像配准方法还包括:
(1)获取目标对象待配准的第四医学图像和第五医学图像。
所述第四医学图像为与所述第五医学图像为不同类型的医学图像或者同一类型不同时间拍摄的医学图像。
(2)根据所述第四医学图像和所述第五医学图像输出第三目标观察影像至显示装置,以在所述显示装置的第三显示窗口交替显示所述第三医学图像和所述第四医学图像。
其中,所述第一显示窗口和第三显示窗口为所述显示装置同一显示界面的两个不同的显示窗口。
(3)根据所述第一目标观察影像和所述第三目标观察影像,对所述目标对象进行图像配准。
需要说明的是,上述实施例中仅举例描述显示装置的图像配准界面显示两 个显示窗口,可以理解的是,在实际应用中可以显示多个显示窗口,例如可以同时显示上述实施例中描述的第一显示窗口,第二显示窗口和第三显示窗口,具体此处不作限定。
另外,本申请实施例中所描述的医学图像,例如第四医学图像,第五医学与图像,第六医学图像均可以参照前述实施例中描述的第一医学图像和第二医学图像,从维度上来说,均可以是二维图像或三维图像,从图像类型上来说,均可以是CBCT图像,CT图像,超声图像(B超图像或彩超图像),核磁共振图像等,具体此处不作限定。
