拖挂式多视角物品检查系统及其使用方法 技术领域
本发明涉及X射线透视成像，特别提供了一种可移动的具有多视角的X射线透视成像系统。
背景技术
X射线透视成像安检设备在机场、轨道交通、港口、政府机关、重大活动场所等具有广泛的应用。一些应用场所的临时性、周期性、突发性、检查量峰谷波动大、甚至野外作业等特点，使得具有移动性能的安检设备成为一种发展趋势。同时由于安全等级要求的不同，一些应用场合对安检设备提出了更高的要求，如希望从多个角度对物品进行检测获得众多视角的图像，以便对受检物品进行综合的细致分析，能更有效地发现藏匿的违禁物品、危险品等。
现有一些技术开始部分适应上述要求。例如，一种自行式辐射物品检查系统及其检查方法，提出了一种设置在自行走机构上的物品检查系统，可在小范围内灵活机动布置，但是不适合远距离转场和野外工作。例如，一种行李扫描车，提出了一种车载式X射线检查装置，可远距离移动，配备的发电机使X射线检查装置可在野外工作，但是相对机场、车站、海关、会议中心等活动空间有限的场所，该装置的占地面积大，不利于在场内进行移动；发电机运转噪音大、有尾气排放，而且由于其和检查装置一同安装在车辆上，在运转时产生的振动会导致扫描图像质量下降；此外，该系统在移动转场时需要具有驾驶资格的专业司机，这无疑更整个系统的工作增加了人力成本。例如，一种中小型车辆辐射扫描检测装置，提出了一种能搬运移动的可组合安装的射线检查系统，且射线源位于门架顶部，扫描方向由宽度变为高度，提高了图像的平面清晰度，但是搬运和安装难度大，成像仍然为普通平面图像，不能分辨深度方向的信息，图像质量提高有限。例如，一种移动式物品专用X射线检查仪，提出了一种集成在拖车上的X 射线检查仪，且通过可旋转的安检平台，可以从多个方向对物品进行检查，从而生成立体图像，实现了较好的检测效果，但是旋转装置检查速度慢，物品检查工作效率低。
针对以上现有技术存在的不足，本发明提出一种可移动的具有多视角的X射线透视成像系统，通过多视角X射线检查装置、电源装置和拖挂车的结合，在受检查物品通过一次时就可获得的其具有深度层次信息的透视图像，检查速度快，图像质量好，危险品检出效率高，同时人力成本低，能够灵活机动地满足不同使用环境的应用需求。

具体实施方式
根据本发明的一个实施例，一种拖挂式多视角物品检查系统包括拖挂车1和安装于拖挂车1上的射线检查装置2。
在本实施例中，拖挂车1包括底盘101、固定于底盘下方的移动轮102、位于底盘一端的拖挂连接装置103、和位于底盘上方的至少一个舱体。移动轮102具有前后轮组，如两个前轮为前轮组，两个后轮为后轮组。底盘101还包括例如转向装置、刹车装置、固定支撑装置等。转向装置用于使移动轮运动过程中易于改变方向，这样增加了拖挂车在小范围内移动位置的灵活性。刹车装置用于对移动轮进行制动，一方面可防止拖挂车移动过程中的速度失控，另一方面可用于拖挂车静止时固定于某个确定位置。固定支撑装置用于在设备处于固定位置，且需要较长时间停放时取代前后轮组对底盘103提供支撑。具体地，固定支撑装置可以是自动或手动的螺旋升降支柱。舱体用于布置射线检查装置2等设备或提供舒适的工作环境，包括至少一个安装射线检查装置2的检查舱105。射线检查装置2可以布置在检查舱105内。射线检查装置2可以平行于拖挂车纵向对称轴线，也可以以其他合适的方式布置在检查舱105内。检查舱105设计有可打开的舱门，用于射线检查装置2工作时，受检查物品可以出入检查舱105。例如，舱门布置在检查舱105的相对于拖挂车1的纵向方向的两侧，由此受检查物品从检查舱一侧进入，从另一侧出来。
拖挂车1使得射线检查装置2获得了灵活的移动能力，且成本较低。在小型场地内进行移动和定位时，无需牵引车头，通过人工或普通外力就可实现，且占用的场地小、操作灵活、无需专业人员即可完成。在中长距离的不同场地之间转场工作时，通过牵引车头，包括专用牵引车头和普通小轿车，可以实现快速移动，且舱体使得射线检查装置2等设备在移动过程中得到充分保护(不会被直接触碰、雨淋、风吹、日晒等)。拖挂车本身也可以进行远距离移动。
射线检查装置2包括射线源201、探测器202、机架203、传输装置204、数据与图像处理系统205、显示与控制装置206。其中机架203为框形结构，内部有检查通道，检查通道下方是传输装置204，射线源201固定在机架203上，可以是一个，也可以是多个，多个时用201a，201b表示，如多个单靶点的普通X射线源，或一个多靶点的分布式X射线源，或多个多靶点的分布式X射线源，或多个普通X射线源与分布式X射线源的组合等。探测器202固定在机架203上，处于与射线源201隔着检查通道相对的位置，通常是多个探测单元组成的探测器阵列，还可以是多排探测器阵列。与多个X射线源对应的，探测器202可以为多组探测器，用202a，202b表示。机架203通常包括骨架、面板、屏蔽装置、安装结构等。传输装置204可以包括三段，分别是位于机架内的主体部分和分别位于物品入口和出口侧的两个延长段，入口延长段和出口延长段与机架的连接处具有连接机构，使得这两段在工作时可以伸展为水平状态，在非工作状态可以折叠起来，以减少占地面积。
用于射线检查装置2的射线源201的一个重要的技术指标是能量。能量决定了X射线的穿透能力，能量越高的X射线，能穿透厚度和密度越大的物体。射线源201产生的X射线是立体发散发射的，通常只用其强度最大的一个方向上的X射线进行透视成像，其它方向上的X射线则被屏蔽掉。原因在于，一方面是防止杂散X射线对成像的影响，另一方面使周围环境的X射线剂量处于国家规定的安全水平。通常使用铅等重金属材料对 X射线进行屏蔽，屏蔽结构的厚度通常与X射线的能量直接相关，能量越高，屏蔽结构的厚度越大，则重量越重。因此能量是双刃剑，能量越高，可以检查尺寸越大的物品对象，但是屏蔽结构也会越厚重，同时能量高的X射线源本身价格也越昂贵。本发明的拖挂式多视角物品检查系统，配置成检查通过尺寸不大于1.5m×1.5m的物品对象，如行李、包裹、邮件、邮包、小型货物等，推荐的射线检查装置2中X射线源201的能量不大于1MeV(即106电子伏特)。一方面X射线源的成本较低，同时屏蔽结构的厚度小，重量轻、成本低，使得射线检查装置2适合小型拖挂车辆的承重要求，如小于1吨，整个拖挂式多视角物品检查系统的灵活性不受影响且成本较低。
X射线源201也可以为多个单靶点的普通X射线源。多个普通X射线源可以在机架203上以围绕检查通道的方式布置，如布置在检查通道的垂直截面上，或检查通道的斜向截面上。这种布置方式可以获得检查通道的不同视角，如顶视+侧视。多个普通X射线源还可以在机架203上以平行(顺延)检查通道的方式布置，如沿着检查通道的物品行进方向进行布置，但是X射线具有不同的出射方向，以不同的角度穿透检查通道(即不同斜角的截面)，同样可以获得检查通道的不同视角，如前向斜视+后向斜视。
X射线源201还可以为一个多靶点的分布式X射线源。分布式X射线源内部具有多个不同位置的靶点，可以从多个不同位置产生X射线。分布式X射线源可以按靶点围绕(或部分围绕)检查通道排列的方式布置在机架203上，相当于从不同的角度观察一个检查通道的截面；还可以按靶点平行检查通道排列的方式布置在机架203上，通过准直器使X射线以不同的斜向角度穿透检查通道，获得检查通道的不同视角。
X射线源201还可以是上述单靶点的普通X射线源和多靶点的分布式X射线源组合以获得检查通道的不同视角的布置。
上述实施方式，均是受检查物品以一定的速度通过检查通道一次，即 可获得多个视角的透视图像，检查速度快。且多视角的检查系统可以获得受检查物品的多层次的透视图像，获得了受检查物品的深度方向的信息，图像信息丰富，成像质量好，提高了检查效果，如危险品的检出效率。
上述实施方式中，探测器202与X射线源201隔着检查通道相对布置，对应的探测器202可以为一组，也可以为多组。在本发明的一个实施例中，多个X射线源或一个X射线源的多个靶点布置在检查通道的同一个截面上，探测器202为一组，也布置在这个截面上，接收各个X射线源或各个靶点产生的X射线。在本发明的另一个实施例中，多个X射线源或一个X射线源的多个靶点产生的X射线穿透检查通道形成多个不同的截面，并且这些截面与检查通道边缘或边缘附近相交于一条线，探测器202为一组，布置在这些截面的交线上，接收各个X射线源或各个靶点产生的X射线。在本发明的又一个实施例中，多个X射线源或一个X射线源的多个靶点产生的X射线穿透检查通道形成多个不同的截面，且这些截面在检查通道边缘附近相交，探测器202具有多组，组的数量与截面的数量相同，即每个截面布置一组探测器用于接收该截面的X射线。
上述实施方式中，探测器为一组时，优选地，多个X射线源或者X射线源的多个靶点配置成按时间交替进行X射线发射的方式进行工作，显示与控制装置206通过逻辑判断，获知某个确定时刻探测器接收的X射线来自某个确定的X射线源或者某个靶点，从而让数据与图像处理系统205用该时刻的探测器202信号构建该X射线源或者某个靶点产生的X射线对检查通道形成的截面的图像。即探测器获得的信息按时间刻度区分到不同视角的截面，用于构建不同视角的透视图像。探测器为一组时，拖挂式多视角物品检查系统具有成本低的优势。
上述实施方式中，探测器为多组时，优选地，多个截面中的X射线源或靶点同时产生X射线，多组探测器同时接收各自截面内X射线源或靶点产生的X射线，数据与图像处理系统205通过探测器组的位置判断信号来源于哪个视角截面，并分别用于构建相应视角截面的透视图像。探测器为 多组时，探测效率更高，检查速度可以更快。需要特别指出的是，探测器为多组时，多个截面中的X射线源或靶点也可以交替产生X射线，能降低杂散X射线的影响，有助于提高图像质量，但是检查速度不一定是最优。
需要特别指出的是，本发明的上述实施例中，X射线源的位置相对检查通道是固定的，即静止的，工作过程中产生X射线的靶点位置是静止的。传统的物品旋转支撑平台或旋转(移动)X射线源来获得多个视角的系统，因为旋转的受检查物品或X射线源是一种动态成像过程，具有不可避免的伪影现象(如靶点移动变长)，影响图像质量。因此本发明的静止X射线源的多视角物品检查系统具有更好的图像质量。
需要特别指出的是，上述实施方式的X射线检查装置2也可以不安装于拖挂车上，而是布置于普通室内场所，也是一套独立完整的多视角物品检查系统。例如，一种多视角物品检查系统的实施方式为：多个X射线源或一个X射线源的多个靶点产生的X射线穿透检查通道形成多个不同的截面，并且这些截面相交于检查通道边缘或边缘附近的一条线，一组探测器202布置在这些截面的交线上，接收各个X射线源或各个靶点产生的X射线。该实施方法具有明显的成本低、检查速度快、图像质量好、危险品检查效率高的有点。
根据本发明一个实施例的拖挂式多视角物品检查系统，还可以包括电源装置3和市电连接装置4。电源装置3用于在没有市电的条件下，如野外、公路路口、广场等，向射线检查装置2提供电力供应。电源装置3可以是发电机、蓄电池组等。市电连接装置4用于在有市电的条件下，如车站、室内场所等，将射线检查装置2快速连接到市电供电系统。市电连接装置4包括电缆线和电缆接头，还可以包括电源开关和电缆卷筒等。本发明的拖挂式多视角物品检查系统，同时配备电源装置3和市电连接装置4，使得系统的环境适用性大大增强，在野外等场所可以通过发电机获得电力进行工作，而在室内场所则可以选择电源连接装置4连接到市电系统，避免了发电机的噪音和尾气对室内环境的影响，同时也避免了发电机的振动 对射线检查装置2的影响。
电源装置3和市电连接装置4可以与射线检查装置2一起安装在检查舱105中。优选地，拖挂车还包括电源舱104，电源装置3和市电连接装置4安装于电源舱中，电源舱通过设置减震、隔音等装置消除发电机工作时的振动、噪音、尾气、散热等对射线检查装置2的影响。
需要特别指出的是，在本发明的不包含电源装置3和市电连接装置4的拖挂式多视角物品检查系统的实施方式中，同过其它方式将外部电源供电连接到射线检查装置2也可使用拖挂式多视角物品检查系统。
本发明的拖挂式多视角物品检查系统，其拖挂车的舱体还可以包括控制舱106，用于给射线检查装置2的运行操作提供一个舒适的环境。控制舱106内安装有射线检查装置2的显示与控制装置206和桌、椅等，设计有供操作人员出入的门。控制舱106还可以进一步安装有照明设备、空调设备、观察窗户等。
下面结合附图对实施方式进一步说明。
图1是一种拖挂式多视角物品检查系统的组成示意，是侧视观察的效果。拖挂式多视角物品检查系统包括拖挂车1和安装于拖挂车1上的射线检查装置2、电源装置3以及市电连接装置4。其中，拖挂车1包括底盘101、固定于底盘下方的移动轮102、位于底盘一端的拖挂连接装置103、和位于底盘上方的舱体。舱体可以有多个，如电源舱104，检查舱105和控制舱106。

图7(b)表示了两个X射线源201a和201b相对于检查通道的物品运动方向具有前后位置关系，且具有较大的距离，但是探测器是布置在一个位置的同一组。X射线源201a和201b产生的X射线以一定的倾斜角度射入检查通道，汇聚在探测器202处，被探测器202接收。
