具体实施方式
以下，将参照附图来描述本公开的实施例。但是应该理解，这些描述只是示例性的，而并非要限制本公开的范围。在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本公开实施例的全面理解。然而，明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。此外，在以下说明中，省略了对公知结构和技术的描述，以避免不必要地混淆本公开的概念。
本公开的各个实施例提供了一种用于展示PET设备的检测结果的方法、装置、电子设备、介质及程序。其中本公开各个实施例中所涉及的PET设备包括r个环，每个环由一组探测器连接而成，该r个环分别垂直于PET设备的轴向设置，其中，r为大于或等于1的整数。
根据本公开的实施例，该用于展示PET设备的检测结果的方法可以通过如下操作来实现。首先，在用户交互界面中分N个区域分别展示N种不同的检测结果，其中，N为大于或等于2的整数。然后基于用户在用户交互界面中执行的显示内容切换操作，切换目标操作区域中所展示的检测结果的内容，其中，目标操作区域为N个区域中的其中之一；该显示内容切换操作用于切换目标操作区域的显示内容。以此方式，用户可以通过在用户交互界面中的显示内容切换操作，来查看需要查看的检查结果内容。本公开实施例中N种不同的检测结果可以包括以下至少二者：PET设备的单一事件或巧合事件的均匀性分数、以单一事件或巧合事件计量的晶体效率、或者r个环中其中一环的单一事件或巧合事件的信息。
根据本公开的实施例，可以分区展示各种不同的检测结果，并且可以通过在用户交互界面上的操作使用户选择希望查看的检查结果，方便操作，易用性强。
图1为根据本公开一实施例的用于展示PET设备的检测结果的方法流程图。
如图1所示，根据该实施例的用于展示PET设备的检测结果的方法可以包括操作S110～操作S120。
首先在操作S110，在用户交互界面中分N个区域分别展示N种不同的检测结果，其中，N为大于或等于2的整数。
根据本公开的实施例，该N种不同的检测结果可以包括以下至少二者：PET设备的单一事件或巧合事件的均匀性分数、以单一事件或巧合事件计量的晶体效率、或者r个环中其中一环的单一事件或巧合事件的信息。
在一些实施例中，可以在第一区域以列表形式展示r个环中其中一环的单一事件或巧合事件的信息，并在第二区域以可视化图形的形式展示以单一事件或巧合事件计量的晶体效率，其中，第一区域和第二区域为N个区域中的不同区域。从而可以将数字化结果以及图形可视化结果分区展示。
以列表形式展示的内容具体可以包括该r个环中其中一环的事件数、计数率、单一事件数、单一事件计数率、或巧合事件均匀性中的至少之一。
以可视化图形的形式展示的内容具体可以包括单一事件晶体效率图、符合事件晶体效率图、或洪水直方图中的至少之一。其中，单一事件晶体效率图用于反映PET设备中的每个探测器所包括的晶体的单一事件分布情况。符合事件晶体效率图用于反映PET设备中的每个探测器所包括的晶体的巧合事件分布情况。洪水直方图用于反映PET设备中的每个探测器中的晶体位置排布。
图2～图4示意了根据本公开各个实施例的用户交互界面的示意图。结合图2～图4对本公开实施例中涉及的用户交互界面进行示例性说明如下。
如图2所示，该用户交互界面200主要包含5个大区域，如下：
区域1可以展示一次检查的单一均匀性分数和巧合事件均匀性分数；
区域2包含三个单选菜单：View Singles Crystal Efficiency Map(单一事件晶体效率图，如图2中区域8中的图形所示)，View Coincidence Crystal Efficiency Map(符合事件晶体效率图，如图3中区域8中的图形所示)，View Flood Histogram(洪水直方图，如图4区域8中的图形所示所示)。点击对应的菜单选项，区域8将会展示对应图形。
区域3以列表形式展示当前环的counts(事件数)，Counts Rate(计数率)，singles(单一事件数)，Singles Rate(单一事件计数率)，Coincidence Uniformity(符合事件均匀性)；
区域8以图形形式展示了可视化图形，晶体环展示当前的环的指定内外层探测器的对应图形；以及
区域7中展示Color Map(颜色带)，用于调节区域8中的可视化图形的颜色；
其中，区域3和区域8分别对应于上述的第一区域和第二区域。
图3和图4中的区域划分与图2一致，不同的是图2、图3和图4中至少区域8中所显示的可视化图形的内容不同。
如图2和图3所示，区域8中分别示出了单一事件晶体效率图和符合事件晶体效率图。其中，单一事件晶体效率图和符合事件晶体效率图均包括有目标环的探测器的排布结构图(如图2中环a和环b组成的环形结构图)、以及该目标环内选定的目标探测器的晶体效率分布图(图2和图3中的图形f)。其中，在图2和图3的示例中，该排布结构图为与目标环具有映射关系的环形图，展示了该目标环中的探测器排布阵列。晶体效率分布图相应地布置在该排布结构图的环形内部，从而整体布局紧凑且美观。
在图2～图4所示的用户界面中所展示的PET设备中，每个探测器具有内外两层晶体，每一组探测器连接而成的环中包括内环和外环两层，其中，内环和外环分别由每一组探测器的内层外两层晶体对应连接组成。相应地，在排布结构图中形成环a和环b两层，其中，环a代表外层晶体、环b代表内层晶体。图中被选中的晶体层c为其所在的探测器的内层晶体，其中，该探测器还包括外层晶体C’。相应的，图形f显示的是晶体层c的单一事件晶体效率分布图或符合事件晶体效率分布图。
可以理解，以上示例的PET设备中探测器包括内外两层晶体仅是一种示例。本公开实施例的方法不限定PET设备中探测器的具体结构。例如，PET设备中探测器也可以仅包括单层晶体，或者还可以包括更多层晶体。
继续参考图1。根据本公开实施例，在操作S110之后可以执行操作S120。
在操作S120，基于用户在用户交互界面中执行的显示内容切换操作，切换目标操作区域中所展示的检测结果的内容，其中，目标操作区域为N个区域中的其中之一。显示内容切换操作用于切换目标操作区域的显示内容。例如可以在N个区域中的一个或多个区域中，提供相应的切换控件。用户可以通过操作该切换控件来切换对应区域中的所展示的检测结果的内容。例如可以在以下多种检测结果之间进行切换展示：整个PET设备整体的检测结果指标、PET设备中某一个环的检测结果指标、某一个环中的某一个探测器的检测结果指标、或者某一个探测器中的某一层晶体的检测结果指标。
图5为根据本公开一实施例的用于展示PET设备的检测结果的方法中用户交互流程图。该方法流程可以对以列表形式展示的第一区域(例如，图2～图4中的区域3)中的检测结果 进行切换展示。其中，第一区域的列表中提供有第一切换控件(如图2示意的第一切换控件4和6)，第一切换控件用于在r个环中的不同环之间进行切换。
如图5所示，根据本公开的实施例操作S120可以包括操作S521～操作S522。
首先在操作S521，基于用户对第一切换控件的操作，确定用户指定的目标环。
然后在操作S522，在第一区域中展示目标环的检测结果。
参考图2，第一切换控件4为next ring，用于指定标签5所指示的当前环的后一环。第一切换控件6为pre ring，用于指定标签5所指示的当前环的前一环。用户可以通过操作第一切换控件4或6，控制区域3中显示哪一环的检测结果，其中，检测结果可以包括该环的的counts(事件数)，Counts Rate(计数率)，singles(单一事件数)，Singles Rate(单一事件计数率)，Coincidence Uniformity(符合事件均匀性)。
图6为根据本公开另一实施例的用于展示PET设备的检测结果的方法中用户交互流程图。该方法流程可以对以可视化图形形式展示的第二区域(例如，图2～图4中的区域8)中的检测结果进行切换展示。其中，第二区域包括至少一个第二切换控件(如图2中所示的两个第二切换控件e)和至少一个第三切换控件(如图2中所示的两个第三切换控件d)。第二切换控件用于在r个环中的不同环之间进行切换。第三切换控件用于在每组探测器中的不同探测器之间进行切换。
如图6所示，根据本公开的实施例操作S120可以包括操作S621～操作S623。
首先在操作S621，基于用户对第二切换控件的操作，确定用户指定的目标环。图2中位于上侧的第二切换控件e表示前一个环，位于下侧的第二切换控件e表示下一个环。用户可以通过操作该两个第二切换控件e来选定要在图8中显示哪个环中的探测器的晶体效率图。
并且在操作S622，基于用户对第三切换控件的操作，确定用户在目标环中指定的目标探测器。图2中位于左侧的第三切换控件d表示前一个探测器，位于右侧的第第三切换控件d表示下一个探测器。用户通过操作该两个第三切换控件d来选定要在图8中显示目标环中哪个探测器的晶体效率图。
根据本公开的另一些实施例，用户还可以在指定了目标环之后，可以通过在目标环的排布结构图上的选择操作来确定目标探测器。在这种情况下，当PET设备中的探测器包括多层晶体(例如，双层晶体时)，在一些实施例中，只要用户选定了某一个探测器中的任意一层晶体(如晶体层c)时，就确定用户选择要展示该晶体层c所在的探测器的晶体效率分布图。在另一些实施例中，当用户选定了某一个探测器中的任意一层晶体(如晶体层c)时，则确定用户仅需要展示该晶体层c的晶体效率分布图。
之后在操作S623，在第二区域展示目标环中目标探测器的可视化图形。当选定目标环和目标探测器后可以在区域8中显示该目标环中目标探测器的可视化图形f。
当第二区域用于显示单一事件晶体效率图或符合事件晶体效率图时(如图2和图3的区域8中的示意)，至少一个第二切换控件e和至少一个第三切换控件d可以布置在排布结构图(包括环a和环b)的环形内部，并位于晶体效率分布图(图2和图3中的图形f)的周边。
当当第二区域用于显示洪水直方图(如图4中的区域8所示)，至少一个第二切换控件e和至少一个第三切换控件d布置在第二区域内，位于洪水直方图(图4中的图形f)的外部。
在图4中，点击左侧的第二切换控件e后将展示上一个环中探测器的洪水直方图，点击右侧的第二切换控件e后将展示下一个环中探测器的洪水直方图。并且左右侧第二切换控件的中间区域将展示当前的环号。点击左侧的第三切换控件d后将展示上一个探测器的洪水直方图，点击右侧的第三切换控件d后将展示下一个探测器的洪水直方图，并且左右侧第三切换控件d的中间区域将展示当前的探测器号。
根据本公开的实施例，在用户交互界面中还设置有色彩条件操作的空间，如图2中区域7的示意。从而可以接收用户在用户界面中执行的色彩调节操作，并响应于色彩调节操作，调节可视化图形的色彩。例如，图2中区域7中展示Color Map(颜色带)，拖动min控件可以调节右侧图形颜色对比度的最小值，从而区域8中展示的图形会相应的变化。拖动Max控件可以调节右侧图形颜色对比度的最大值，从而区域8中展示展示的图形对比度会相应的变化。
根据本公开的实施例，可以将数字化结果以及图形可视化结果分区展示，简洁直观。非专业人员也可非常直观方便操作界面，易用性强。而且可以在用户界面中展示多种检测结果，例如，PET设备整体的检测指标、或者PET设备中的某一个环的检测结果指标、或者某个环中的探测器的检测结果指标等，实现一个界面展示多层信息的效果。在第二区域中通过分层展示，可以展示各个环中各个探测器的单一事件晶体效率图、符合事件晶体效率图、和每个探测器的洪水直方图。与此同时，在第一区域中还可以以列表形式展示各个探测器事件数、计数率、单一事件、单一计数率、符合事件均匀性等信息，使得PET结果的展示内容丰富且直观。
