    • A method for imaging an object by means of photoneutron transmission is provided, which comprises the steps of: collimating the photoneutron rays passing through the object by means of a neutron collimator so as to determine the position information of the photoneutron rays based on the position of the neutron collimator; detecting the collimated photoneutron ray beams by means of a detector module, wherein the detector module includes a neutron moderator and at least one thermal neutron detector located within the neutron moderator, wherein the neutron moderator converts the photoneutrons into thermal neutrons, and wherein the thermal neutron detector measures the thermal neutrons so as to obtain attenuation information of the photoneutron ray beams upon passing through the object; and integrating the position information and the attenuation information so as to form an image of the corresponding part of the object. The method determines the position of the photoneutron rays based on the position of a neutron collimator, so as to overcome the problem of incapability of imaging due to loss of position information of the photoneutrons during moderation thereof. The method also images the object by arranging detector module arrays.
    • 提供了一种通过光子中子传输对物体进行成像的方法,其包括以下步骤:通过中子准直器准直通过物体的光中子射线,以便基于位置信息确定光子中子射线的位置信息 中子准直仪; 通过检测器模块检测准直的光子中子射线束,其中检测器模块包括中子减速剂和位于中子慢化剂内的至少一个热中子探测器,其中中子减速剂将光中子转化为热中子,并且其中热中子 检测器测量热中子,以便在通过物体时获得光中子射线束的衰减信息; 并且对位置信息和衰减信息进行积分,以形成对象的对应部分的图像。 该方法基于中子准直器的位置来确定光中子射线的位置,从而克服由于光调节剂在其调节期间的位置信息的损失而不能成像的问题。 该方法还通过布置检测器模块阵列对对象进行成像。
