Description

一种用于X射线检查设备的旋转弧形探测器盒 技术领域
本发明涉及一种旋转弧形探测器盒，特别涉及一种用于X射线检查设备的旋转弧形探测器盒,属于物品安全检测技术领域。
背景技术
X射线经常用于对物品进行安全检查，例如用于识别行李、包裹或集装箱中的违禁物品。X射线成像检测设备是应用于机场、车站、码头、会议、展览等场合必需的检测手段之一。在进行安全检查的过程中，需要待检查物品与X射线源及检测器进行相对运动，检测装置能主动检测并对通过的物品进行成像显示。为此，目前的X射线安全检查系统的工作方式有两种：第一种是安全检查操作时射线源和探测器不固定，通过射线源和探测器的移动实现对被检物品的扫描，这种情况往往通过车载安全检查系统来实现。第二种是安全检查操作时射线源和探测器静止不动，被检物品可以穿过射线扫描区域移动，完成扫描，如行李安全检查系统。而为了得到更好的扫描图像质量，往往采用安全检查操作时射线源和探测器固定不动的方式。
一般成像系统主要包括以下几部分。X光机，通过射线发生装置，产生稳定的X射线；前准直器，被安置在X光束的前端，对X射线的扫描范围进行调节；后准直器：在X射线到达接收区域的范围进行准直处理。探测器阵列，接收X光机发出的X射线。其主要工作原理为：X光机发射的X射线经过前准直器穿透通过的物品，再经过后准直器，最后探测器接收穿透的射线并转化成电信号，经过处理形成图像并显示物品内部形状。
现有的X射线检查设备主要是L型探测器盒的直线性与侧照式的X光机布置，直线型探测器距光机靶点距离差异性大，经常在算 法和物理方面进行远近探测器的图像处理。往往有分辨率低，图像效果差等问题。

具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
如图1所示，本发明提供一种用于X射线检查设备的旋转弧形探测器盒，包括圆弧形探测器集成块1和使旋转弧形探测器和转动的转动机构2；圆弧形探测器集成块1的开口部朝向X光机辐射源3，圆弧型探测器固定在远离开口部一侧的回转轴10上，使圆弧型探测器集成块沿回转轴10为中心旋转，转动机构2设置在远离圆弧形探测器集成块1开口的一侧与圆弧形探测器集成块1连接。下面对本发明 提供的旋转弧形探测器盒展开详细说明。
如图1所示，圆弧型探测器集成块1通过带孔的回转支承件11固定在回转轴10上，回转支撑件11上的孔套合在回转轴10上，回转支撑件11固定在圆弧型探测器集成块远离开口部一侧。
如图1、图3至图5所示，旋转弧形探测器盒的转动机构2是电动推杆装置2，电动推杆装置2包括通过通电自动伸缩的连接杆20，电动伸缩杆包括两个端部，其中一个端部固定在X射线检查设备上，另一个端部连接圆弧型探测器集成块远离开口部一侧的牵引轴22上，牵引轴22与回转轴10之间有足够大的距离。电动伸缩杆2对圆弧型探测器集成块1的力矩足够大，使圆弧型探测器集成块沿回转轴10转动。为了进一步提高旋转弧形探测器盒在电动推杆装置2伸缩时灵活转动，电动推杆装置2的伸缩杆的一端是通过转动轴21固定在X射线检查设备上的。在电动伸缩杆伸缩时，电动推杆装置2也沿转动轴转动。在此需要说明的是，本发明中，转动机构2不限于电动推杆装置2，能使圆弧型探测器集成块沿回转轴10转动的装置都可以实现本发明(例如，液压装置、气动装置、齿轮、链轮等传动机构。)。
如图2所示，圆弧形探测器集成块1的圆弧上布设有多个探测器晶体5。探测器晶体5的中心和靶点的连线与探测器晶体5和圆弧的切线垂直。各个探测器晶体5的中心和靶点的连接线与对应探测器晶体5与圆弧的切线垂直时对能量的接收效果最好。多个探测器晶体5在X光机辐射源3射线的一定张角为α的范围内，相邻的探测器晶体并排安装并与发射源靶点等距离布置，且相邻探测器晶体的间距不大于0.5mm如此设置，相比L型探测器盒有效降低了射线的散射问题。多个探测器晶体5采用并排安装的结构，在减小散射，提高丝分辨率方面效果更好。另外探测器晶体5并排安装，理论间隙很小，没有射线的空间反射，可以有效降低边缘射线的散射。
如图1至图4所示，圆弧形探测器集成块1两侧设置有两套基准 定位装置，在结构设计方面，将旋转弧形探测器盒模块化设计，将探测器晶体5及其安装板做成模块整体调整，在安装以前，先借助外部平台等开放区域，将各个探测器晶体5相对准直缝，调整在同一个基准面内，即各个探测器晶体5的基准一致，相对位置就一致。这样的操作简单、方便，而且容易找到基准面。另外该旋转弧形探测器盒有一个固定的转动机构2、旋转弧形探测器盒两侧有两套基准定位装置，形成一个独立的旋转弧形探测器盒模块。
本发明提供的用于X射线检查设备的旋转弧形探测器盒随着电动推杆装置2推杆的伸缩在X光机辐射源3射线的张角为α的范围内绕回转轴10往复旋转，使探测器对准不同通道的不同放射源。下面以本以旋转弧形探测器盒应用于双通道X射线检查设备为例，对旋转弧形探测器盒的工作过程详细说明。本旋转弧形探测器盒旋转动力采用电动推杆装置2驱动，旋转弧形探测器1旋转至左、右两个通道时采用两套基准定位装置定位旋转弧形探测器1的旋转到位情况，基准定位装置优选是带接近传感器的探测器基准块。如图3所示，当使用左通道时，连接杆20打开伸出，圆弧形探测器集成块1绕回转轴10顺时针旋转。当圆弧形探测器集成块1向左旋转到位后，通过探测器左基准块定位圆弧形探测器集成块1的旋转面的相对位置，利用探测器左基准块的接近传感器确定旋转到位情况，实现旋转弧形探测器盒在左通道的准确到位。同理当使用右通道时，如图4所示，连接杆20收缩，圆弧形探测器集成块1绕回转轴10逆时针旋转。当圆弧形探测器集成块1向右旋转到位后，通过探测器右基准块定位圆弧形探测器集成块1的旋转面的相对位置，利用探测器右基准块的接近传感器确定旋转到位情况，实现旋转弧形探测器盒在右通道的准确到位。旋转弧形探测器盒两个通道之间绕回转轴10切换时，各探测器晶体5相对应靶点位置一致，也就是发射和接收距离相差不大，实现两通道指标的变化一致性，便于图像处理。通过本发明提供的旋转弧形探测器盒对行李检测时， 对行李的扫描位置和扫描面积大，可以实现行李箱平放在输送机上检测。本发明通过旋转机构实现不同通道的不同X光机的射线探测需求，根据安检机的输送带信号接收到的货物信号，驱动电动推杆装置2的推杆，实现对应的收缩和打开，选择性的根据探测器左/右基准块的传感器准确定位，成为不同通道的探测器。本发明提供的旋转弧形探测器盒在双通道探测器中的位置属于几何对称位置，所以两个通道的图像的变形处理可以采用同一种方法处理，几何校正方面更容易。
综上所述，本发明提供的用于X射线检查设备的旋转弧形探测器盒，可以解决两通道指标的差异性、图像的变形处理不一致性等问题。本发明采用相邻探测器晶体并排安装的结构，在减小散射，在提高丝分辨率方面效果更好。本发明的探测器布置结构，行李箱可以平放在输送机上，扫描效果更好，省去输送托盘，图像效果更好，缓解安检人员的工作量。
以上实施方式仅用于说明本发明，而并非对本发明的限制，有关技术领域的普通技术人员，在不脱离本发明的精神和范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本发明的范畴，本发明的专利保护范围应由权利要求限定。
