具体实施方式
为使本公开的技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
一方面，本公开实施例提供了一种束光器，如附图1-附图3所示，包括：开设有辐射窗口101的基座1，该束光器还包括：设置于基座1上的调节体2，调节体2用于调节辐射窗口101的大小。
本公开实施例提供的束光器，在基座1上设置调节体2，通过调节体2可调节辐射窗口101的大小，如此，当X射线焦点距成像位置之间的距离发生变化时，针对辐射区域的变化，通过调节体2将辐射窗口101调节至相应大小，以适应上述变化，提高束光器的适用性。
需要说明的是，X射线医疗设备的X球管射线发射点与基座1上所开设的辐射窗口101及射线探测器的最大有效探测面积成几何锥投影关系，以保证窗口以外的射线不会对探测器电路及患者进行额外的非预期照射。
调节体2设置于基座1上，用来调节辐射窗口101的大小，对于能够实现该功能的调节体2的结构，以下进行示例阐述：
作为一种示例，如附图2所示，基座1上具有与调节体2相适配的导向通道102，导向通道102内具有辐射窗口101，通过使调节体2沿导向通道102移动，以改变对辐射窗口101的遮挡面积，进而调节辐射窗口101的大小。
其中，导向通道102与调节体2相互适配，以使调节体2仅仅沿导向通道102移动，而不会在导向通道102内发生不必要的位移。举例来说，导向通道102为矩形通道时，调节体2可以为与其相适配的矩形块体。
导向通道102可以为规则的几何结构，也可以为异形结构，只要满足与其相适配的调节体2在其中移动时能够改变辐射窗口101的大小和形状即可。
本公开实施例中，导向通道102不仅仅可以允许调节体2在其中移动，也 可以允许由多个方向将调节体2从其中取出，例如沿其移动方向，或者沿垂直于基座1表面的方向等，满足该类要求的导向通道102的结构包括但不限于：矩形通道、梯形通道等。
当然，期望调节体2仅能够沿移动方向在导向通道102内移动，此时，导向通道102包括：止位段，该止位段用于在垂直于基座1表面(即上、下表面)的方向上对调节体2进行止位，防止调节体2由该方向上发生位移，提高调节体2在导向通道102中移动时的稳定性。
对于具有止位段的导向通道102的结构，以下举例来说：其一，导向通道102可以包括宽度不同的至少两段，其中，位于最下部的段具有最大的宽度，并且作为止位段。例如，导向通道102可以为凸字形通道(即两段式)(参见图5)，相应地调节体2可以为凸形块体。
其二，导向通道102可以为一段式，但是其宽度由下至上逐渐减小，其中，位于下部的段可以作为止位段。例如，导向通道102可以为燕尾形通道(参见图6)，半圆弧形通道等。
需要说明的是，以基座1为基准，其上表面所在方位为上，下表面所在方位为下，上述涉及的方位名词“上、下”均可以此为标准。
可以在基座1上表面设置凸块，将导向通道102开设于凸块上即可。导向通道102的底部可以与基座1上表面持平，如此，开设于基座1上的辐射窗口101可位于导向通道102底部。
当辐射窗口101位于导向通道102底部时，可以仅设置一个调节体2，也可以同时设置多个调节体2，使调节体2底部对辐射窗口101进行部分遮挡，来达到调节辐射窗口101大小的目的。
当采用多个调节体2时，可以从更多方向上对辐射窗口101进行调节，获得更多种形状及坐标位置的辐射窗口101，提高辐射窗口101的适应范围，所以，可以同时采用多个调节体2。
以下就使用多个调节体2的情形进行阐述：
在一种可能的实现方式中，如附图1所示，调节体2包括：相对设置且移动方向平行的两个第一调节块201。应用时，可使两个第一调节块201相对运动、相反运动，或者其中一个固定，另一个移动的方式，进而可获得不同类型的辐射窗口101。
两个第一调节块201的结构可以相同，也可以不同，第一调节块201的形状包括但不限于：矩形条块状、燕尾形条块状、T形条块状、弧形条块状等。
在另一种可能的实现方式中，如附图4所示，调节体2包括：相对设置且移动方向平行的两个第二调节块202；以及相对设置且移动方向平行的两个第三调节块203。其中，第二调节块202的移动方向与第三调节块203的移动方向垂直。
应用时，可以使两个第二调节块202相对运动、相反运动或者其中一个固定，另一个移动，和/或，使两个第三调节块203相对运动、相反运动或者其中一个固定，另一个移动，以获得不同类型的辐射窗口101。
其中，第二调节块202可以在两个第三调节块203之间移动，当然，第三调节块203也可以在两个第二调节块202之间移动。
其中，第二调节块202和第三调节块203的结构可以相同，也可以不同，两者的形状包括但不限于：矩形条块状、燕尾形条块状、T形条块状、弧形条块状等。
在一种示例中，可以使第二调节块202为燕尾形条块状，第三调节块203为T形条块状。
综上可知，当采用多个调节块时，可以对其中一个或同时多个调节块进行移动，以达到从不同方向调节辐射窗口101大小及形状的目的。可以理解的是，调节块的数目越多，所能获得的辐射窗口101形式就越多。
当调节体2移动至特定位置处后，为了防止其发生不期望的位移，造成辐射窗口101大小有偏差，如附图1所示，本公开实施例提供的束光器还可以包括紧固件3，该紧固件3用于将调节体2固定于基座1上。
举例来说，该紧固件3包括但不限于：螺钉、销钉、卡扣等。
作为一种示例，该紧固件3可以为螺钉，其中，基座1上具有螺钉孔4，调节体2上具有过螺钉通孔5，应用时，使螺钉穿过调节体2上的过螺钉通孔5后，与基座1上的螺钉孔4螺纹连接，即可实现紧固作用。
其中，调节体2上的过螺钉通孔5可以与螺钉大小相适配，此时，移动调节体2至期望位置处后，将螺钉进行固定即可。
考虑到调节体2在不同位置处时，需要在基座1上相应位置处设置螺钉孔4，如此可能会造成在基座1上设置多个螺钉孔4。在尽可能减少基座1上螺钉孔4 数目的前提下，为了使调节体2能够固定在不同的位置处，可以使调节体2上的过螺钉通孔5为腰型孔，可以理解的是，腰形孔的长度大于螺钉直径，当需要调节调节体2的位置时，可以拧松螺钉，而无须将其拆卸下来，然后直接移动调节体2至期望的位置，拧紧螺钉即可。
上述就调节体2在导向通道102内移动，以调节辐射窗口101大小的方式进行了阐述，以下就调节体2的另外一种实现方式进行阐述：
在另一种可能的示例中，该调节体2可包括：多个联动的第四调节块，其中，多个第四调节块可进出辐射窗口101。
通过使多个第四调节块同时进出辐射窗口101，也能够达到改变辐射窗口101大小的目的。
举例来说，第四调节块可以呈螺旋片状，多个第四调节块绕辐射窗口101沿周向设置于基座1内部，即，在基座1内部设置于多个第四调节块相适配的圆形容纳腔。
第四调节块还可以呈矩形片状，顺次联接并可实现联动，在辐射窗口101一侧的基座1内部可以设置一矩形容纳腔，以容纳部分或全部第四调节块。
可以理解的是，上述多个联动的第四调节块所组成的调节体2的结构，可以参见相机的快门结构，本公开实施例在此对其不作具体阐述。
本公开实施例提供的束光器在应用状态时，其基座1可安装于X射线医疗设备的球管组件管套输出窗前方，并且使基座1上辐射窗口101的中心与球管组件管套输出窗的中心保持一致。
在束光器安装过程中，为了可以对其位置进行微调，如附图1所示，可以在基座1上设置多个腰形安装孔6，利用紧固螺钉穿过该腰形安装孔6将基座1固定于球管组件管套输出窗前方即可。当需要调整束光器位置时(即，调整射野大小时)，只需拧松紧固螺钉，使基座1以及调节体2移动至期望的位置，随后拧紧螺钉，实现固定即可。
示例地，基座1可以为矩形板状，在基座1的四个角部可分别设置一个腰形安装孔6即可。
另一方面，本公开实施例提供了一种X射线医疗设备，该X射线医疗设备包括上述的任一种束光器。
本公开实施例提供的X射线医疗设备，基于采用了上述束光器，能够在X 射线焦点距成像位置之间的距离发生变化时，针对辐射区域的变化，通过调节体将辐射窗口调节至相应大小，具有更强的适用性。
以上所述仅是为了便于本领域的技术人员理解本公开的技术方案，并不用以限制本公开。凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
