下面参考图1-图5描述根据本发明实施例的放射治疗用患者坐姿设备100。
如图1所示，根据本发明实施例的放射治疗用患者坐姿设备100包括：安装平台10、治疗床组件20、支撑调节组件30和三维影像组件40。放射治疗用患者坐姿设备100包括影像扫描功能和放射治疗功能，本申请以影像扫描功能为例对放射治疗用患者坐姿设备100进行描述。
其中，安装平台10为治疗床组件20、支撑调节组件30以及三维影像组件40的安装载体，安装平台10可以构造为地面的一部分，也可以构造为单独的框架结构，通过嵌设的方式与地面配合。
参照图1，治疗床组件20用于将患者固定，以便于通过三维影像组件40对患者进行影像扫描。支撑调节组件30设置在安装平台10的下方，而且支撑调节组件30与治疗床组件20相连，并用于调节治疗床组件20相对安装平台10的位置，以便于将患者调节至合适的影像扫描角度和位置，保证对患者的影像扫描效果。其中，安装平台10设置有过孔，支撑调节组件30在过孔处与治疗床组件20相连，并用于支撑治疗床组件2020，而且可以对治疗床组件20的位置进行调节。可以理解的是，过孔的设置便于将位于安装平台10下方的支撑调节组件30与治疗床组件20连接，节省布置空间。
进一步地，三维影像组件40包括立柱组件41和三维影像设备42，立柱组件41设置在安装平台10上，而且立柱组件41沿竖向方向延伸，三维影像设备42可移动地安装于立柱组件41，并且三维影像设备42在水平投影方向上与治疗床组件20对应，三维影像设备42用于对患者影像扫描。
具体地，立柱组件41用于支撑固定三维影像设备42，并且可以根据影像扫描需求调节三维影像设备42在立柱组件41上的位置，以调节三维影像设备42相对治疗床组件20(同时也是相对患者)的位置，从而将三维影像设备42调节至适于对患者不同部位进行影像扫描的位置，进一步保证放射治疗用患者坐姿设备100的影像扫描效果。
由此，本申请先通过治疗床组件20对患者进行固定，以便于患者保持适于进行影像扫描的姿态，并通过支撑调节组件30对治疗床组件20相对于安装平台10的位置进行调节，将患者的待扫描部位调节至便于与三维影像设备42对应的区域，进一步对三维影像设备42的位置进行调节，以将三维影像设备42调节至对患者待扫描部位进行影像 扫描的位置，保证放射治疗用患者坐姿设备100的影像采集效果。本申请先对患者进行姿态固定，再通过多级调节的方式将患者与三维影像设备42对应，提升放射治疗用患者坐姿设备100对患者的影像采集效果。
可以理解的是，当需要对患者进行多角度影像扫描时，可以通过支撑调节组件30对患者的位置进行调节，并进一步调节三维影像设备42与患者的对应位置，可以满足放射治疗用患者坐姿设备100对患者不同部位或相同部位的不同角度的扫描及治疗需求，无需患者变换多种姿态以及反复启动放射治疗用患者坐姿设备100，减少放射治疗用患者坐姿设备100的生产、运行及维护成本。
需要说明的是，目前对肿瘤患者的治疗过程通常在旋转治疗室或固定治疗室内进行，当需要对患者的不同部位进行治疗时，需要体积较大的旋转设备对患者扫描治疗，并且固定治疗室可治疗患者肿瘤的种类较少，局限性大。同时，由于场地和设备配套的限制，导致治疗室(旋转治疗室或固定治疗室)的建造成本过于昂贵。本申请中的放射治疗用患者坐姿设备100通过对治疗床组件20以及三维影像设备42的位置调节，可以将患者以不同姿态与三维影像设备42对应，且调节方式简单，对场地尺寸的需求相对于常规的旋转治疗室或固定治疗室更小，可以降低治疗室的建造成本。
根据本申请实施例的放射治疗用患者坐姿设备100，通过治疗床组件20对患者的姿态进行固定，通过支撑调节组件30调节治疗床组件20的位置，以对患者的位置进行调节，可以满足放射治疗用患者坐姿设备100对患者不同部位或相同部位的不同角度的扫描及放射治疗需求，从而放射治疗用患者坐姿设备100可以多方向、多角度调整患者的治疗位置和扫描位置，可以满足患者不同部位的放射治疗需求，适用范围广。

可以理解的是，患者与患者之间的身高可能存在差异，当患者的身材相对高大时，可以通过升降组件23驱动治疗床本体22上升，以调节治疗床本体22与患者的配合位置，便于治疗床本体22的位置与患者的身材相匹配；当患者的身材相对矮小时，可以通过升降组件23驱动治疗床本体22下降，以调节治疗床本体22与患者的配合位置，便于治疗床本体22的位置与患者的身材相匹配。治疗床组件20可以根据患者需要治疗 的部位调整治疗床本体22的高度，并且调节方式简单且可靠性高。

在本发明的一些实施例中，支撑调节组件30设置有基座33，所述水平移动平台311设置在基座33上，并且水平移动平台311通过旋转平台312、倾斜平台313与治疗床组件20相连，当水平移动平台311相对基座33运动以调节其相对安装平台10的水平位置时，旋转平台312和倾斜平台313随水平移动平台311同步运动，以带动治疗床组件20在水平方向上运动，调节治疗床组件20相对安装平台10在水平方向的位置。
进一步地，旋转平台312通过倾斜平台313与治疗床组件20相连，当旋转平台312转动时，倾斜平台313将带动治疗床组件20同步转动，旋转平台312用于调节治疗床组件20在安装平台10上的朝向，以对患者的面向方向进行调节。可以理解的是，在旋转平台312的作用下，治疗床组件20中固定患者的朝向可以朝向左侧、右侧、前侧、后侧等方向，具体可以是水平范围内的任意角度。其中，旋转平台312的转动方式为绕竖直延伸的轴线转动，以调节治疗床组件20在水平方向上的朝向。
如图4所示，倾斜平台313与治疗床组件20的底座21相连，以调节底座21相对于安装平台10的倾斜角度，从而调节治疗床组件20的俯仰角度。如：将固定在治疗床组件20上的患者前倾或后仰。
需要说明的是，水平移动平台311、旋转平台312和倾斜平台313自下向上依次布 置，可以提升治疗床调节组件31调节过程的稳定性。其中，治疗床调节组件31的调节方式为自下向上逐步调节，即先通过水平移动平台311调节治疗床组件20的水平位置，再通过旋转平台312调节治疗床组件20的朝向方向，最后通过倾斜平台313调节治疗床组件20的俯仰角度，调节方式全面且可靠性高。

参照说明书附图1-5描述根据本发明实施例的放射治疗用患者坐姿设备100的使用步骤：
首先，基于使用需求选择性地对安装平台10高度进行调节；
其次，将患者固定在治疗床组件20上，以一种坐姿为例，患者坐在坐垫223上，并倚靠在床板222上，同时手扶扶手224、脚步和腿部分别与脚步限位快、腿部限位块24支撑配合，此时可根据患者的身材对治疗床本体22相对底座21的位置进行调节，以将治疗床组件20与患者身材匹配；
进一步地，当需要将患者前倾或后仰时，可以通过固定网与支架2221配合将患者的上半身与床板222固定，对患者的姿态进行约束；
更进一步地，根据患者需要治疗的部位通过水平移动平台311、旋转平台312、倾斜平台313对治疗床组件20的水平位置、朝向及俯仰角度进行调节；
此时患者相对安装平台10的位置已经确定，可以通过驱动组件414调节三维影像设 备42相对患者的位置，具体包括三维影像设备42与患者之间的距离、三维影像设备42相对患者的扫描照射方向，以将三维影像设备42调节至适于对患者影像扫描的位置。
需要说明的是放射治疗用患者坐姿设备100包括：影像扫描工作模式和放射治疗模式，多个部件在影像扫描工作模式和放射治疗模式中的调节方式相同。
在患者处于影像扫描工作模式下，三维影像设备42可以通过沿旋转立柱412延伸方向移动的方式对患者进行扫描，扫描结束后，三维影像设备42可以移动至旋转立柱412的顶部。在患者处于放射治疗模式下，可以通过支撑调节组件30、治疗床组件20对患者的位置及姿态进行确定，此时放射治疗用患者坐姿设备100可以满足患者不同部位肿瘤的放射治疗需求。
