Description

能量校正方法、装置、电子设备、探测设备及存储介质 技术领域
本申请涉及射线探测技术领域，特别是涉及一种能量校正方法、装置、电子设备、探测设备及存储介质。
背景技术
高能射线可以应用于安检、食品安全、地质勘探、核医学等多种探测场景中，对高能射线(例如X射线、γ射线)的探测通常需要利用闪烁探测器这一类的探测手段。闪烁探测器的工作原理是通过闪烁晶体将高能射线沉积之后产生大量可被光电转换器件响应的可见光子，再由光电转换器件输出电信号，后续通过采集处理得到高能射线的能量、时间等信息。其中，采集处理的电子学环节是非常重要的一环，其在一定程度上影响了闪烁探测器的性能。
目前在采集处理的电子学部分，会出现输入的能谱与输出的能谱不能在通过线性变换之后完全重合的问题。例如MVT(Multi-Voltage Threshold，多电压阈值采样)数字化方法，其是一种常用于核医学方向的闪烁探测器电子学方法，通过设置多个电压阈值采集由闪烁探测器产生的闪烁脉冲，再通过重建闪烁脉冲完成能量时间的信息获取，由于其是采用设置电压阈值来采样这一种方式，因此会出现如上所述的输入输出非线性的问题，由于能量的输出与输入成非线性关系，因此通过该输出能量不能准确获得输入的脉冲的能量。

以下参考附图对本申请的一些优选实施例进行说明。应当注意的是，以下描述是为了说明的目的，并不旨在限制本申请的保护范围。
在一个实施例中，参照图1，提供一种能量校正方法。本实施例提供的能量校正方法包 括以下步骤：
步骤S200、同步采集脉冲信号并分别获取各脉冲信号的待校正能量值和标准能量值。
其中，待校正能量值指的是通过采集设备对脉冲信号进行采集，进而处理得到的能量值，由于采集设备的局限性，该能量值与真实能量值往往存在偏差，因此需要对其进行校正。本实施例中，在获取各脉冲信号的待校正能量值的同时，还获取到各脉冲信号所对应的标准能量值，标准能量值指的是脉冲信号所对应的真实能量值，其可以是由电子测量仪器(例如示波器)进行测量得到，以保证能够得到各脉冲信号的真实能量值。
步骤S400、根据各脉冲信号的待校正能量值和标准能量值，获取能量校正函数。
当得到各脉冲信号的待校正能量值和标准能量值后，可以对各脉冲信号的待校正能量值与标准能量值之间的差异规律进行分析，进而得到能量校正函数，能量校正函数可以体现待校正能量值与标准能量值之间的数学关系。
步骤S600、基于能量校正函数，对各脉冲信号的待校正能量值进行校正。
当得到能量校正函数后，即可将各脉冲信号的待校正能量值代入至能量校正函数，以对待校正能量值进行校正，即，将采集设备采集到的脉冲信号的待校正能量值代入能量校正函数中，可以得到该脉冲信号的真实能量值，以完成对待校正能量值的校正。
本实施例中，可以对某一时间段的脉冲信号进行采集，以得到该时间段中脉冲信号的待校正能量值和标准能量值，进而得到能量校正函数，利用能量校正函数可以对其他时间段采集到的脉冲信号的待校正能量值进行校正。
本实施例提供的能量校正方法，在采集各脉冲信号的待校正能量值的同时，还同时采集各脉冲信号的标准能量值，基于待校正能量值和标准能量值，即可获取得到能量校正函数，基于该能量校正函数即可对各脉冲信号的待校正能量值进行校正，由此，仅需建立能量校正函数即可对各脉冲信号的能量值进行校正，校正方式相对于神经网络校正方式来说，无需复杂的计算，所需占用的资源较少，校正过程简单，即使是少资源的芯片也适用上述能量校正方法，通用性强。
在其中一个实施例中，参照图2，步骤S200，即同步采集脉冲信号并分别获取各脉冲信号的待校正能量值和标准能量值的步骤包括：
步骤S210、控制第一采集设备10和第二采集设备20对脉冲信号进行同步采集。
本实施例中，第一采集设备10可以是实际应用场景下用于采集脉冲信号的采集设备，例如MVT采集设备等。第二采集设备20可以是电子测量设备，例如示波器等，通过电子测量设备可以得到脉冲信号的真实电学参数。通过第一采集设备10和第二采集设备20对脉冲 信号进行同步采集，以确保对应于第一采集设备10的待校正能量值与对应于第二采集设备20的标准能量值对应的是同一时间的脉冲信号。
步骤S220、获取第一采集设备10采集到的各脉冲信号的能量值，以得到待校正能量值，获取第二采集设备20采集到的各脉冲信号的能量值，以得到标准能量值。
在第一采集设备10和第二采集设备20同步采集到一定数量的脉冲信号后，可以通过积分运算获取第一采集设备10采集到的各脉冲信号的能量值，以此作为待校正能量值，也可以通过积分运算获取第二采集设备20采集到的各脉冲信号的能量值，以此作为标准能量值。由此可获得各脉冲信号的待校正能量值和标准能量值。其中，积分运算方式可以包括牛顿积分法、黎曼积分法、数值积分法等，对此不做具体限制。
在其中一个实施例中，步骤S210，即控制第一采集设备和第二采集设备对脉冲信号进行同步采集的步骤包括：当第一采集设备10对当前的脉冲信号采集完毕时，输出触发信号至第二采集设备20，以指示第二采集设备20保留当前采集到的脉冲信号。
参照图3，在实际应用中，光电转换器件输出的脉冲信号可以同步输入至第一采集设备10和第二采集设备20，第二采集设备20作为一种电子测量设备，例如示波器，其可以对输入的所有信号进行采集，但是在没有外界触发的情况下，其往往不会主动保留采集到的数据，即无法与第一采集设备10采集到的数据进入后续处理分析环节。因此，为了保留第二采集设备20采集到的数据，以备后续处理分析，在一个实施例中，第一采集设备10对当前输入的脉冲信号采集完毕时，会产生一采集完毕的标志信号，并将该标志信号作为第二采集设备20的触发信号，发送至第二采集设备20，当第二采集设备20接收到触发信号时，保留当前采集到的脉冲信号，由此当前输入至第一采集设备10和第二采集设备20的脉冲信号可以在被第一采集设备10采集到时，也能够同步被第二采集设备20采集和保留。
以第一采集设备10为MVT采集设备，第二采集设备20为示波器为例，MVT采集设备采集到脉冲信号时(即，脉冲信号的幅值超出MVT采集设备的预设阈值)，其输出一个采集完毕的标志信号，将该标志信号输出至示波器，示波器以该标志信号作为触发信号以触发保留该脉冲信号，当示波器的非采集通道接收到该触发信号，则触发采集通道对当前采集到的脉冲信号进行保留。一般地，触发信号的电压值大于示波器的触发电压，假设，示波器的触发电压为1V，则触发信号的电压值可以大于1V，如3V，由此可确保触发信号可以被示波器采集到。通过上述方式，可以保证MVT采集设备和示波器可以同时采集到同一时间段的脉冲波形。
除了上述通过在第一采集设备采集完毕时触发第二采集设备保留采集到的数据之外，还 可以通过其他方式来确保第一采集设备和第二采集设备同步采集获取到同一时间段的脉冲。例如，各采集设备往往存在一定的采集条件，在数据满足条件时才能够被采集到，因此可以在脉冲信号输入至各采集设备之前，预先判断其是否能被各采集设备所采集到，若能，则输入脉冲信号至各采集设备，同时指示第二采集设备保留输入的脉冲信号。
具体地，在另一实施例中，参照图4，步骤S210，即控制第一采集设备和第二采集设备对脉冲信号进行同步采集的步骤包括：
步骤S211、获取对应于第一采集设备10的采样阈值。
第一采集设备10的采样阈值可以用于与待输入的脉冲信号的幅值进行比较，当待输入的脉冲信号的幅值能够越过采样阈值，则该脉冲信号可以被第一采集设备10采集到。
在一个实施例中，第一采集设备10包括MVT采集设备，采样阈值为MVT采集设备的最高采样阈值，当脉冲信号的幅值能够越过MVT采集设备的最高采样阈值时，MVT采集设备可以采集到该脉冲信号的完整波形。
步骤S212、根据采样阈值设定比较阈值。
当获取到第一采集设备10的采样阈值后，即可以根据采样阈值设定比较阈值，该比较阈值可以是在脉冲信号输入至各采集设备之前，用于与脉冲信号的幅值进行比较，进而预先判断该脉冲信号能否被第一采集设备10采集。
在一个实施例中，比较阈值可以是大于采样阈值的数值。由于比较阈值大于采样阈值，则当脉冲信号的幅值大于比较阈值时，脉冲信号的幅值必然可以越过采样阈值，即可确定该脉冲信号可以被第一采集设备10采集到。例如，MVT采集设备的最高采样阈值为80V，可以设定比较阈值为81V或85V或90V或100V等，当待输入的脉冲信号的幅值大于比较阈值，其必然能够越过MVT采集设备的最高采样阈值，即可确定MVT采集设备可以完整地采集到当前待输入的脉冲信号的完整波形。
本领域技术人员应当理解的是，能够被MVT采集设备成功采集的脉冲信号，必然可以被示波器采集到，因此，本实施例中，可以仅根据第一采集设备的采样阈值来确定比较阈值，即，仅需确认脉冲信号能否被第一采集设备采集到即可。
步骤S213、当脉冲信号的目标参数值大于比较阈值，则输出脉冲信号至第一采集设备10和第二采集设备20，并输出触发信号至第二采集设备20，以指示第二采集设备20保留当前采集到的脉冲信号。
脉冲信号的目标参数值可以包括脉冲信号的幅值，当其大于比较阈值，即可确定该脉冲信号可以被第一采集设备10采集到，因此将脉冲信号输出至第一采集设备10和第二采集设 备20，以便第一采集设备10和第二采集设备20采集该脉冲信号，同时输出触发信号至第二采集设备20，当第二采集设备20收到触发信号，则对当前采集到的脉冲信号进行保留，由此，第一采集设备10和第二采集设备20可以同步采集获取同一时间的脉冲信号。
本实施例中，参照图5，可以设置一比较器30来实现上述比较阈值与脉冲信号的目标参数值的比较，当脉冲信号的目标参数值大于比较阈值，则将脉冲信号同步输出至第一采集设备10和第二采集设备20，同时输出高电平方波信号至第二采集设备20，以作为触发信号，进而，第一采集设备10和第二采集设备20可以同步采集到脉冲信号，同时，第二采集设备20还能够对采集到的脉冲信号进行保留，便于后续处理。
在其中一个实施例中，参照图6，步骤S400，即根据各脉冲信号的待校正能量值和标准能量值，获取能量校正函数的步骤包括：
步骤S410、根据各脉冲信号的待校正能量值和标准能量值，获取待校正能量值关于标准能量值的散点图。
当获取得到各脉冲信号的待校正能量值和标准能量值时，即可建立待校正能量值关于标准能量值的散点图。具体地，参照图7，X轴可以表示各脉冲信号的待校正能量值，Y轴可以表示各脉冲信号的标准能量值，一个脉冲信号即对应一个X值和Y值，记为坐标(X，Y)，采集到的若干个脉冲信号即可形成集合(Xi，Yi),(Xi，Yi)为第i个被采样到的脉冲信号的待校正能量值和标准能量值的组合，其中，i为小于或等于被采集到的脉冲信号总个数的正整数。将(Xi，Yi)各点绘制在二维坐标系中，即可得到各个脉冲信号的待校正能量值关于标准能量值的散点图。
步骤S420、根据散点图中各个位置点的分布规律，获取能量校正函数。
对散点图中各个位置点进行分析，可确定出各个位置点的分布规律，可进一步确定各个位置点对应的待校正能量值与标准能量值之间的数学关系，由此可构建出能量校正函数，通过能量校正函数可以对待校正能量值进行校正，得到能量校正值，理想情况下，某个脉冲信号的能量校正值即为该脉冲信号的标准能量值，但考虑到实际应用中难免存在误差，因此经能量校正函数校正之后得到的能量校正值可以存在些许误差。
在其中一个实施例中，参照图8，步骤S420，即根据散点图中各个位置点的分布规律，获取能量校正函数的步骤包括：
步骤S421、提取散点图中的若干目标位置点。
其中，目标位置点可以包括散点图中的若干走势点。通过散点图可以较为清晰地看出各个位置点的走势，为简化校正过程，可以根据各个位置点的走势提取出散点图中主要的走势 点即可。
提取走势点的方式可以采用重心提取法，即计算获得散点图中横坐标不同位置对应的若干个重心点的坐标。具体地，可将横坐标分成若干份，可以计算出每一份内所有点的横坐标的平均值，即为每一份内重心点的横坐标，以及计算出每一份内所有点的纵坐标的平均值，即为每一份内重心点的纵坐标，由此可获得每一份内的重心点的横纵坐标，即提取出散点图中的若干重心点，以此作为走势点。例如，横坐标的总长度为X，将其分为N份，X＝1000，N＝500，则每一份的长度为2，第一份为0～2，第二份为2～4，第三份为4～6，以此类推，假设0～2范围内有100个点，则计算这100个点的横坐标的平均值以及纵坐标的平均值，得到0～2范围内的重心点坐标，以此类推，可获得500个重心点的坐标，即得到500个重心点，以此作为散点图的走势点。
提取走势点的方式也可以采用中心提取法，由于本实施例中散点图的中心与重心相同，因此，中心提取法的方式与重心提取法的方式相同，在此不做赘述。
在另一实施例中，目标位置点可以包括散点图中的所有点，即直接提取出散点图中所有的点，用于后续函数的确定。
步骤S422、根据若干目标位置点的坐标，求解n次函数，其中n为不包括0的自然数，以得到拟合函数。
例如，当提取出若干目标位置点，可尝试从一次函数开始求解，以得到一次拟合函数。
具体地，可以先拟合出直线方程：y＝kx+b，其中，x为对应于第一采集设备的待校正能量值，y为经校正之后的校正值。
将获取到的目标位置点的坐标代入至上述直线方程中，进而可求解出k和b的值，进而求解出一次函数，以此作为拟合函数。
步骤S423、验证拟合函数是否符合预设要求，若不符合，则调整n次函数为n+1次函数，直至得到的拟合参数符合预设要求，以最终符合预设要求的拟合函数作为能量校正函数。
当初步确定了拟合函数后，可以对其进行验证，即对该拟合函数的校正精度进行判断，若精度符合预设要求，则无需调整，直接以该拟合函数作为能量校正函数，若精度不符合预设条件，则需要对其进行进一步调整，即，调整n次函数为n+1次函数，并求解n+1次函数，再对n+1次函数进行验证，直至得到符合要求的拟合函数，以此作为能量校正函数。
在其中一个实施例中，参照图9，步骤S423，即验证拟合函数是否符合预设要求，若不符合，则调整n次函数为n+1次函数，直至得到的拟合函数符合预设要求，以最终符合预设要求的拟合函数作为能量校正函数的步骤包括：
步骤S423a、根据散点图中各位置点对应的待校正能量值与标准能量值，确定拟合函数的误差量。
拟合函数的误差量可以是经拟合函数校正后的校正值与标准能量值之间的误差量。具体地，可以随机选取散点图中的若干个位置点，再通过拟合函数对散点图中各位置点的待校正能量值进行校正，得到校正值，即，将各位置点，即各个脉冲信号所对应的待校正能量值分别代入至拟合函数中，得到校正值，再比对各个位置点所对应的校正值与标准能量值，根据比对结果确定拟合函数的误差量。具体地，可以得到对应于各个位置点的校正误差值(即校正值与标准能量值的差值)，可以根据各个位置点的校正误差值确定拟合函数的误差量。
在一个实施例中，可以筛选出各个位置点的校正误差值中的最大值，以此作为拟合函数的误差量。
例如，求解出一次函数为：y＝0.8x+0.3，x为待校正能量值，y为校正后所得的校正值，假设提取出散点图中存在的四个点，坐标分别为(1，1.5)、(3，3.5)、(6，5.5)、(10，9.5)，将四个点的横坐标分别代入至一次函数中的x，得到的y值分别为1.1、2.7、5.1、8.3，由此可见，各个y值(即校正值)与散点图中各点的纵坐标(即标准能量值)均存在差异，误差值分别为0.4、0.8、0.4、1.7，其中最大的误差值为1.7，即，拟合函数的误差量为1.7。
步骤S423b、若误差量超出允许范围，则根据目标位置点的坐标继续求解n+1次函数，以得到新的拟合函数，依此类推，直至拟合函数的误差量位于允许范围内。
当得到拟合函数的误差量后，判断误差量是否超出允许范围，回到上述示例，假设误差的允许范围为0～1.5，则拟合函数的误差量1.7超出了允许范围0～1.5，则认为该拟合函数的精度不符合要求，一次函数不能够作为能量校正函数，需要继续求解二次函数。
二次函数的方程为y＝ax2+cx+d，与求解一次函数的方法类似，即，将获取到的散点图中的目标位置点的坐标代入至二次函数的方程中，求解得到a、b、c的值，进而求解出二次函数，以此作为拟合函数。再通过上述验证方式对该拟合函数的精度进行验证，在此不再赘述，若符合要求，则以该拟合函数作为能量校正函数，若不符合要求，则进一步求解三次函数，以此类推，直至符合要求，以最终符合预设要求的拟合函数作为能量校正函数。
本实施例中，误差的允许范围可以根据实际需求设定，如在测井场景中，在总能量道址为256道的情况下，误差的允许范围可以是一个能量道址以内，若误差量超出一个能量道址，则需继续调整拟合函数。
