Description

放射治疗装置及放射治疗方法 技术领域
本发明涉及放射治疗装置，具体涉及一种放射治疗装置及放射治疗方法。
背景技术
随着肿瘤放射学与材料科学的发展，高能光子治疗装置、质子治疗装置及重离子治疗装置都在进行不断的发展，这三种技术方案各自具有自身的优点，也同时具有其缺点，当某些病例需要利用多种治疗方案才能获得更优的治疗效果时，病患需要在不同的治疗室中完成摆位及治疗等过程，这样，既延长了治疗时间，增加了重复摆位的环节和治疗费用。目前还没有将上述治疗***整合起来的方案。
发明内容
为解决上述问题，本发明的目的在于提供一种放射治疗装置及放射治疗方法，可以同时配置光子治疗组件和质子治疗组件，或同时配置光子治疗组件和重离子治疗组件，克服现有技术的弊端。
为达到上述目的，本发明的技术方案是：
一种放射治疗装置(也称为加速器治疗装置)，所述放射治疗装置还括：
光子治疗组件：包括支架、主机架和加速器，所述主机架可旋转的安装于支架上，所述加速器安装于所述主机架上；所述主机架带动加速器围绕等中心点旋转，加速器出射的射线的轴线始终穿过一个基准点：等中心点；
质子治疗组件或重离子治疗组件：质子治疗组件用于生成用于治疗的质子束；重离子治疗组件用于生成用于治疗的重离子束；
所述质子治疗组件出射的质子束或重离子治疗组件出射的重离子束的轴线始终穿过所述等中心点。
目前质子治疗设备(质子治疗组件)或重离子治疗设备(重离子治疗组件)体积较大，而光子治疗设备(光子治疗组件，例如X射线放射治疗设备)已完成小型化，且可以将加速器安装在一个可旋转的主机架上，实现射线束可以从一个环形(甚至球面的一部分)上不同点射向等中心点，即光子治疗设备的射线束的入射角度在一定范围内可以调整。而质子治疗设备和重离子治疗设备还远没有实现小型化，其质子束和重离子束一般只能沿固定轴线出射，无法实时调整入射角度。因此要将光子治疗设备与二者进行结合有诸多难点，本发明以光子治疗设备的治疗基准点即等中心点为整个***的基准点，使质子治疗设备(质子治疗组件)或重离子治疗设备(重离子治疗组件)出射的质子束或重离子束的轴线始终通过该基准点，那么，二者则可以同时或分别对一次摆位成功的患者进行治疗，可以优化治疗计划，集合两种治疗***各自的优势，共同来完成治疗，特别对于某些复杂的病例，二者集合可以以更低的代价来更好的完成治疗任务。
进一步的，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线与水平线平行。在实际应用中，为了便于配合病患摆位，质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线与水平线平行，这样尽管质子束或重离子束的出射轴线是固定不变的，也便于通过多维度改变治疗床的倾角及旋转角度，来获得质子束或重离子束的最佳入射角度，同时，光子治疗组件的加速器在一个以等中心点为圆心的圆弧上旋转(某些加速器可以做倾角调整的***即球面刀***是以等中心点为球心的球面上运动)，二者之间互不干扰，光子的入射角度及发射时机、治疗床的多维角度可以和质子束或重离子束的发射时机进行有机优化整合，从而使得两种治疗方案得以有机的集合起来。
进一步的，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线固定不变。
进一步的，所述主机架上设有一个供质子治疗组件或重离子治疗组件出射的质子束或重离子束穿过的窗口。一般而言，光子治疗设备 旋转的轴线是穿过等中心点的一条水平线，光子射线束所在的平面与该水平线垂直，当光子治疗设备做俯仰运动时(球面运动)，光子射线束所在的平面与该水平线呈非九十度的夹角，为了更加优化整个***在治疗室中的结构，质子束或重离子束沿该水平线出射最为适宜，更优的是治疗床位于光子治疗设备的正面，而质子治疗设备或重离子治疗设备的出射点位于光子治疗设备的背面，这样质子束或重离子束穿过光子治疗设备并沿上述水平线到达等中心点，这里在光子治疗设备的主机架上设有一个供质子治疗组件或重离子治疗组件出射的质子束或重离子束穿过的窗口，使得光子治疗设备无论如何运行，其结构部件都不会对质子束或重离子束的通过造成阻碍。同样，这样的布局，也使得质子治疗设备或重离子治疗设备不会对光子治疗设备的运行构成影响，也不会占用其他空间，从而对其他设备或工作人员的工作造成阻碍。
进一步的，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线与加速器的旋转轴线在同一平面上。
本发明还提供一种放射治疗方法，同时配置光子治疗组件和质子治疗组件，或同时配置光子治疗组件和重离子治疗组件，包括以下步骤：
第一、以光子治疗组件的等中心点为治疗的基准点；
第二、供质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线均始终穿过所述基准点；
第三，以所述基准点为准对病患进行摆位；
第四，利用光子治疗组件和/或质子治疗组件，或，利用光子治疗组件和/重离子治疗组件对病患进行放射治疗。
进一步的，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线与水平线平行。
进一步的，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线固定不变。
进一步的，所述主机架上设有一个供质子治疗组件或重离子治疗 组件出射的质子束或重离子束穿过的窗口。
进一步的，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线与加速器的旋转轴线在同一平面上。

具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细的说明。
本发明的一种实施例，如图1和图2所示，为达到上述目的，本发明的技术方案是：
一种放射治疗装置，所述放射治疗装置还括：
光子治疗组件：包括支架1、主机架11和加速器12，所述主机架11可旋转的安装于支架1上，所述加速器12安装于所述主机架11上；所述主机架11带动加速器12围绕等中心点3旋转，加速器12出射的射线的轴线13始终穿过一个基准点：等中心点3；
质子治疗组件或重离子治疗组件2：质子治疗组件用于生成用于治疗的质子束；重离子治疗组件用于生成用于治疗的重离子束；
所述质子治疗组件出射的质子束或重离子治疗组件出射的重离子束的轴线22始终穿过所述等中心点3。
目前质子治疗设备(质子治疗组件)或重离子治疗设备(重离子治疗组件)体积较大，而光子治疗设备(光子治疗组件，例如X射线放射治疗设备)已完成小型化，且可以将加速器安装在一个可旋转的主机架上，实现射线束可以从一个环形(甚至球面的一部分)上不同点射向等中心点，即光子治疗设备的射线束的入射角度在一定范围内 可以调整。而质子治疗设备和重离子治疗设备还远没有实现小型化，其质子束和重离子束一般只能沿固定轴线出射，无法实时调整入射角度。因此要将光子治疗设备与二者进行结合有诸多难点，本发明以光子治疗设备的治疗基准点即等中心点为整个***的基准点，使质子治疗设备(质子治疗组件)或重离子治疗设备(重离子治疗组件)出射的质子束或重离子束的轴线始终通过该基准点，那么，二者则可以同时或分别对一次摆位成功的患者进行治疗，可以优化治疗计划，集合两种治疗***各自的优势，共同来完成治疗，特别对于某些复杂的病例，二者集合可以以更低的代价来更好的完成治疗任务。
在实际应用中，由于质子束或重离子束目前无法在使用时改变出射角度，但为了使得其与光子治疗设备相互配合，因此其质子束或重离子束的轴线必须经过等中心点，那么可以选择的出射角度有很多，但考虑到与治疗床的联动，以及与光子治疗设备之间的配合，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线与水平线平行。在实际应用中，为了便于配合病患摆位，质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线与水平线平行，这样尽管质子束或重离子束的出射轴线是固定不变的，也便于通过多维度改变治疗床的倾角及旋转角度，来获得质子束或重离子束的最佳入射角度，同时，光子治疗组件的加速器在一个以等中心点为圆心的圆弧上旋转(某些加速器可以做倾角调整的***即球面刀***是以等中心点为球心的球面上运动)，二者之间互不干扰，光子的入射角度及发射时机、治疗床的多维角度可以和质子束或重离子束的发射时机进行有机优化整合，从而使得两种治疗方案得以有机的集合起来。
进一步说，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线是水平的且固定不变。
进一步的，所述主机架上设有一个供质子治疗组件或重离子治疗组件出射的质子束或重离子束穿过的窗口14。一般而言，光子治疗设备旋转的轴线是穿过等中心点的一条水平线，光子射线束所在的平面与该水平线垂直，当光子治疗设备做俯仰运动时(球面运动)，光 子射线束所在的平面与该水平线呈非九十度的夹角，为了更加优化整个***在治疗室中的结构，质子束或重离子束沿该水平线出射最为适宜，更优的是治疗床位于光子治疗设备的正面，而质子治疗设备或重离子治疗设备的出射点位于光子治疗设备的背面，如图1和图2所示，这样质子束或重离子束穿过光子治疗设备并沿上述水平线到达等中心点，这里在光子治疗设备的主机架上设有一个供质子治疗组件或重离子治疗组件出射的质子束或重离子束穿过的窗口，使得光子治疗设备无论如何运行，其结构部件都不会对质子束或重离子束的通过造成阻碍。同样，这样的布局，也使得质子治疗设备或重离子治疗设备不会对光子治疗设备的运行构成影响，也不会占用其他空间，从而对其他设备或工作人员的工作造成阻碍。这里所述的窗口14可以是贯穿的物理通孔，也可以是在质子束或重离子束穿过的路径上没有可以对其产生阻碍或阻碍不会影响治疗效果的物质，也可以是部分这类不会对其产生阻碍或阻碍不会影响治疗效果的物质，和物理空腔的组合。
图1中的治疗床4既可以是传统的样式，也可以是机械臂支撑的可以多维调整的结构，也可以是座椅或平板和座椅之间可以转换的结构形式。
关于光子治疗装置(光子治疗组件)、质子治疗设备(质子治疗组件)、重离子治疗设备(重离子治疗组件)现有技术中多有涉及，在此不做赘述。
进一步的，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线与加速器的旋转轴线在同一平面上。
本发明还提供一种放射治疗方法，同时配置光子治疗组件和质子治疗组件，或同时配置光子治疗组件和重离子治疗组件，包括以下步骤：
第一、以光子治疗组件的等中心点为治疗的基准点；
第二、供质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线均始终穿过所述基准点；
第三，以所述基准点为准对病患进行摆位；
第四，利用光子治疗组件和/或质子治疗组件，或，利用光子治疗组件和/重离子治疗组件对病患进行放射治疗。
进一步的，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线与水平线平行。
进一步的，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线固定不变。
进一步的，所述主机架上设有一个供质子治疗组件或重离子治疗组件出射的质子束或重离子束穿过的窗口。
进一步的，所述质子治疗组件或重离子治疗组件出射的质子束或重离子束的轴线与加速器的旋转轴线在同一平面上。
以上所述的仅是本发明的优选实施方式，应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
