Description

图像显示控制方法、装置、电子设备及计算机存储介质 技术领域
本申请实施例涉及医疗设备领域，尤其涉及一种图像显示控制方法、装置、电子设备及计算机存储介质。
背景技术
图像引导放射治疗(Image Guided Radiation Therapy，IGRT)是在放射治疗前或放射治疗中采集患者肿瘤靶区图像，将采集图像与治疗计划中得到的参考图像进行比对，确定肿瘤靶区位移及形变大小并进行校准，以确保对患者肿瘤靶区的精确照射。
目前图像引导治疗技术主要包括三维图像引导和六维图像引导。六维图像引导由于能够反映当前摆位的三维旋转量是否符合临床要求，得到了广泛的应用。在相关技术中，在IGRT设备将摆位阶段得到的摆位图像与计划阶段得到的参考图像在六维方向(X、Y、Z三个平移方向及绕X、Y、Z轴的三个旋转方向)上进行配准之后，直接在IGRT显示界面上显示六维配准后的摆位图像。然而，目前的患者支撑装置大部分为三自由度，无法对三维旋转量进行校准，在IGRT显示界面上显示六维配准后的摆位图像会误导操作者认为当前摆位的三维旋转量符合要求，造成放射治疗不准确。

具体实施方式
为了使本领域的人员更好地理解本申请实施例中的技术方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请实施例一部分实施例，而不是全部的实施例。基于本申请实施例中的实施例，本领域普通技术人员所获得的所有其他实施例，都应当属于本申请实施例保护的范围。
针对现有的IGRT六维影像引导，在IGRT设备将摆位阶段得到的摆位图像与计划阶段得到的参考图像在六维方向(X、Y、Z三个平移方向及绕X、Y、Z轴的三个旋转方向)上进行配准之后，直接在IGRT设备的显示界面上显示六维配准后的摆位图像。由于目前的患者支撑装置大部分为三自由度，无法对三维旋转量进行校正，在IGRT上显示六维配准后的摆位图像会误导操作者认为当前摆位的三维旋转量符合要求，造成放射治疗不准确。
基于上述技术方案中的不足，本申请实施例通过获取对摆位图像和参考图像进行六维配准的配准结果，在患者支撑装置为三自由度时，在显示界面上显示按照配准结果中的三维平移量对摆位图像进行校准后的第一显示图像，该第一显示图像直观反映三自由度的患者支撑装置的三维配准结果，因此根据第一显示图像可以清楚了解患者的当前摆位的真实情况，由此可以做出当前摆位是否符合要求的正确判断，提高放射治疗的精度。
下面结合本申请实施例附图进一步说明本申请实施例具体实现。
图1为本申请实施例提供的一种图像显示控制方法的流程图，该图像显示控制方法应用于图像引导放射治疗设备。如图1所示，该方法包括如下步骤：
S101、获取对摆位图像和参考图像进行六维配准的配准结果，该配准结果包括三维平移量和三维旋转量。
本实施例中，参考图像是指在计划阶段对患者靶区进行影像拍摄得到的图像，例如，可以是电子计算机断层扫描(Computed Tomography，CT)图像、磁共振成像(Magnetic Resonance Imaging，MRI)图像、正电子发射计算机断层显像(positron emission tomography，PET-CT)图像等。在计划阶段，治疗医师在诊断床上对患者进行定位，例如患者靶区位于头部，采用立体定位头架等对患者头部进行定位，又例如患者靶区位于体部，采用负压袋对患者体部进行定位，在定位完成之后，对患者靶区进行影像拍摄得到参考图像。
本实施例中，摆位图像是在摆位阶段对患者靶区进行影像拍摄得到的图 像，摆位图像例如可以是锥形束CT(Cone Beam CT,CBCT)图像。摆位阶段是在计划阶段与治疗阶段之间的一个阶段，也可以认为是治疗阶段的一部分。在摆位阶段，患者躺卧在放射治疗设备的患者支撑装置上，治疗医师根据患者靶区位置对患者进行固定，利用放疗设备的影像设备对患者靶区进行影像拍摄得到摆位图像。
由于在计划阶段和摆位阶段，患者在两种不同的设备上躺卧时，体位可能会在六维方向(X、Y、Z三个平移方向及绕X、Y、Z轴的三个旋转方向)上发生变化。因此需要将摆位阶段得到的摆位图像与计划阶段得到的参考图像在六维方向上进行配准对比，从而得到配准结果，在本实施例中，配准结果可以包括在X、Y、Z三个平移方向上的三维平移量，即在左右方向、前后方向和上下方向上的三个平移量，其可以分别用LAT、VRT和LNG表示。配准结果还可以包括绕X轴旋转、绕Y轴旋转和绕Z轴旋转的三个旋转量，分别用俯仰角PITCT、偏航角YAW和翻滚角ROLL表示。
S102、当患者支撑装置为三自由度时，在显示界面上显示按照三维平移量对摆位图像进行校准后的第一显示图像。
本实施例中，在患者支撑装置为三自由度时，示例性地，在患者支撑装置为三维床时，患者支撑装置仅能在左右、前后、上下三个方向上移动时，此时可以通过移动患者支撑装置对体位差异引起的三维平移量进行校正，而无法对体位差异引起的旋转量进行校正，因此，在显示界面上仅显示按照三维平移量对摆位图像进行平移后的图像，以直观反映真实物理世界中当前摆位，即直观反映真实物理世界中三自由度的患者支撑装置三维配准后的结果，避免现有技术中在患者支撑装置为三自由度时在显示界面上显示六维配准后的图像，误导患者支撑装置的操作者以为当前摆位的三维旋转量符合要求，带来不精确的放射治疗的问题。
本申请实施例提供的图像显示控制方法中，对摆位图像和参考图像进行六维配准的配准结果，在患者支撑装置为三自由度时，在显示界面上显示按照配准结果中的三维平移量对摆位图像进行校准后的第一显示图像，该第一显示图像直观反映三自由度的患者支撑装置的三维配准结果，因此根据第一显示图像患者支撑装置的操作者或治疗医师等可以清楚了解患者当前摆位的真实情况，由此可以做出当前摆位是否符合要求的正确判断，提高放射治疗的精度。
需要说明的是，在本实施例中，在步骤S102之前还可以包括确定患者 支撑装置为三自由度。当患者支撑装置为三自由度时，执行步骤S202。当患者支撑装置不为三自由度时，根据按照三维平移量和三维旋转量中与相应的自由度对应的一组偏移量对摆位图像进行校准，在显示面板上显示校准后的图像。例如，在患者支撑机构为六自由度时，可以直接按照三维平移量和三维旋转量对摆位图像进行校准，并在显示界面上显示六维配准后的图像。
此外，需要说明的是，在本实施例中，在患者支撑装置为三自由度时，除了显示按照三维平移量对摆位图像进行校准后的第一显示图像之外，还可以在显示界面上显示按照三维平移量和三维旋转量对摆位图像进行校准后的第二显示图像。同时显示按照三维平移量对摆位图像进行校准后的第一显示图像和按照三维平移量和三维旋转量对摆位图像进行校准后的第二显示图像，可以便于患者支撑装置的操作者或治疗医师比较第一显示图像和第二显示图像，更直观了解患者的当前摆位距离理想摆位(六维校准)的差距，从而判断当前患者摆位是否符合临床要求，进而可以实现更安全和精确的放射治疗。
在图1所示实施例的基础上，进一步地，参照图2，本申请实施例还提供了另一种图像显示控制方法，该方法包括如下步骤：
S201、获取对摆位图像和参考图像进行六维配准的配准结果，配准结果包括三维平移量和三维旋转量。
S202、当患者支撑装置为三自由度时，在显示界面上显示按照三维平移量对摆位图像进行校准后的第一显示图像。
S203、判断三维旋转量中的至少一个旋转量是否大于预设阈值；
S204、当三维旋转量中的至少一个旋转量大于预设阈值时，在显示界面上显示提示消息，提示消息用于指示对患者进行摆位。
本实施例中，除了配准结果包括三维平移量和三维旋转量之外，步骤S201和步骤S202分别与图1所示实施例中的步骤S101和步骤S102相同，为了避免重复，此处不再赘述。
本实施例中，对摆位图像和参考图像进行六维配准得到三维平移量和三维旋转量。由于在患者支撑装置为三自由度时，通过移动患者支撑装置可以对三维平移量进行校正，但无法对三维旋转量进行校正。若此时三维旋转量中的至少一个阈值超出预设阈值，不对三维旋转量进行校正，IGRT设备的加速器直接出束进行治疗，则会出现漏照射或多余照射现象，这样会严重影响到临床治疗效果，也会对患者正常组织造成不必要的损伤。
为了避免上述情况的出现，在本实施例中，在对摆位阶段得到的摆位图像和计划阶段得到的参考图像进行配准，得到三维平移量和三维旋转量之后，还将三维旋转量与预设阈值进行比较，在三维旋转量中存在至少一个旋转量大于预设阈值时，在显示界面上显示提示消息，要求重新对患者进行摆位，以此校正摆位的三维旋转量，从而进行更安全和精确的放射治疗。其中，预设阈值可以由治疗医师或者其他患者支撑装置的操作者根据实际需要设定。
示例性地，如图3a所示，在显示界面上显示有用于输入预设阈值的文本框，治疗医师可以根据实际需要在文本框内输入预设阈值，例如在图3中，预设阈值为1度。在显示界面上还显示有用于配准图像的图像显示区域，在对摆位图像和计划图像进行配准得到三维平移量和三维旋转量之后，在图像显示区域内显示按照三维平移量对摆位图像进行校准后的第一显示图像。此时，若三维旋转量大于预设阈值，如图3b所示，在显示界面上弹出对话框，要求患者支撑装置的操作者重新对患者进行摆位，以校正摆位阶段的三维旋转量。
需要说明的是，在图3a中的显示界面上显示用于输入预设阈值的文本框仅是一种示例，在其他实现方式中，可以以下拉菜单或其他形式来使用户输入预设阈值，或者也可以采用默认阈值，在显示界面上显示任何用于输入预设阈值的任何控件。此外，如图3b所示，在三维旋转量中的至少一个旋转量大于预设阈值时，在显示界面上弹出对话框来提示患者支撑装置的操作者重新对患者进行摆位仅是一种示例。在其他实现方式中，还可以以语音提示或灯光报警等方式对患者支撑装置的操作者进行提示。
应理解，本实施例中，在三维旋转量均小于预设阈值时，可以理解为三维旋转量在摆位旋转误差的允许范围内，在这种情况下通过移动患者支撑装置对三维平移量进行校正后，IGRT设备的加速器可以直接出束，进行放射治疗。
可选的，为了便于治疗医师或患者支撑装置的其他操作人员直观观察三维平移量和三维旋转量，可以在显示面板中显示三维平移量和三维旋转量。如图3a所示，在显示面板上以配准偏差表的形式显示了三维平移量和三维旋转量，然而，应当理解，图3a所示的三维平移量和三维旋转量的显示形式仅为一种示例，在其他实现方式中，三维平移量和三维旋转量可以以图示等形式显示，本实施例对此不做限定。
本实施例中，通过设置预设阈值来对三维旋转量进行管理，在三维旋转 量超出阈值时发出提示信息，要求患者支撑装置的操作者对患者重新进行摆位来校正三维旋转量，由此可以实现更安全和精确的放射治疗。
在图2所示实施例的基础上，进一步地，参照图4，本申请实施例提供了又一种图像显示控制方法，该方法除了包括上述步骤S201至步骤S204。该方法还包括以下步骤：
S205、检测用户在显示界面上的操作；
S206、响应用户操作，在显示界面上显示按照三维平移量和三维旋转量对摆位图像进行校准后的第二显示图像。
本实施例中，例如，在显示界面上显示有用于将三维旋转量运用到图像上的控件，用于执行图像显示控制方法的装置可以检测用户对显示界面上的该控件的操作。当用户在显示界面上对该控件的操作时，响应于检测到该用户操作，该装置可以按照三维旋转量对第一显示图像进行旋转，得到第二显示图像，或者可以按照三维平移量和三维旋转量对摆位图像进行平移和旋转，得到第二显示图像，并将第二显示图像显示在显示界面上的图像显示区域。由于第二显示图像是按照三维平移量和三维旋转量进行校准后的图像，因此第二显示图像为六维配准后的图像。六维配准后的图像可以反映患者在完美摆位状态下的影像，治疗医师可以根据六维配准后的图像观察患者的断层解剖结构，直观了解患者的当前摆位距离理想摆位的差距，从而判断当前患者摆位是否符合临床要求，进而可以实现更安全和精确的放射治疗。
示例性地，参照图5a，在显示界面上显示有将三维旋转量运用到图像上的勾选框。在缺省情况下，该勾选框未被勾选。当该勾选框未被勾选时，如图5a所示，在显示界面上的图像显示区域显示按照三维平移量对摆位图像进行校准后的第一显示图像，即三维配准后的图像。当该勾选框被勾选时，如图5b所示，在显示界面上的图像显示区域显示按照三维平移量和三维旋转量对摆位图像进行校准后的第二显示图像，即六维配准后的图像。可选的，当该勾选框被勾选时，如图5c所示，在显示界面上显示的图像显示区域同时显示按照三维平移量对摆位图像进行校准的第一显示图像，以及按照三维平移量和三维旋转量对摆位图像进行校准后的第二显示图像，由此便于患者支撑装置的操作者或治疗医师直观比较第一显示图像和第二显示图像。
需要说明的是，在图5a、图5b和图5c中的显示界面上以勾选框形式表示将三维旋转量运用到图像上的控件仅是一种示例。在其他实现方式中，将 三维旋转量运用到图像上的控件还可以以图标或其他形式来表示，本实施例对此不做限定。
本申请实施例中，可以根据用户在显示界面上的操作来确定是否显示六维配准后的第二显示图像。在检测到用户在显示界面上的操作时，按照三维平移量和三维旋转量对摆位图像进行校准，显示反映患者在完美摆位状态下的六维配准后的图像，使得治疗医师可以根据该图像观察患者的断层解剖结构，直观了解患者的当前摆位距离完美摆位的差距，从而判断当前患者摆位是否符合临床要求，进而带来更安全和精确的放射治疗。
需要说明的是，在本实施例中，步骤S205和步骤S206可以在步骤S203和步骤S204之前执行，也可以在不执行步骤S203和步骤S204的情况下执行，本实施例对此不作限定。
