动物活体成像(又称为动物扫描成像)技术是指应用影像学方法，在不损伤动物的前提下，对活体状态下的生物过程进行组织、细胞和分子水平和定量研究的技术。在进行动物扫描成像时，一般需要将动物放置于扫描舱内，然后由相应的扫描设备对其进行扫描成像。在动物扫描成像过程中，扫描舱还需要对放置于其内的待扫描动物的生理状态(例如，呼吸、心电等)进行监控。通过合理设置扫描舱的结构，可以在简化扫描舱的结构的同时，为待扫描动物提供一个适宜的环境，降低待扫描动物被影响的风险，提高对待扫描动物的生理状态信号测量的准确性和效率，便于实验人员对其进行操作。另外，由于待扫描动物的种类、大小等可能各不相同，在扫描前需要根据不同的扫描对象和扫描模态来更换不同规格的扫描舱，在这过程中也就会涉及到对扫描舱进行识别。如何降低扫描舱的识别成本、提高扫描舱的识别效率和准确率，也是目前值得关注的问题。

具体实施方式
为了更清楚地说明本申请实施例的技术方案，下面将对实施例描述中所需要使用的附图作简单的介绍。显而易见地，下面描述中的附图仅仅是本申请的一些示例或实施例，对于本领域的普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图将本申请应用于其它类似情景。除非从语言环境中显而易见或另做说明，图中相同标号代表相同结构或操作。
应当理解，本文使用的“系统”、“装置”、“单元”和/或“模块”是用于区分不同级别的不同组件、元件、部件、部分或装配的一种方法。然而，如果其他词语可实现相同的目的，则可通过其他表达来替换所述词语。
如本申请和权利要求书中所示，除非上下文明确提示例外情形，“一”、“一个”、“一种”和/或“该”等词并非特指单数，也可包括复数。一般说来，术语“包括”与“包含”仅提示包括已明确标识的步骤和元素，而这些步骤和元素不构成一个排它性 的罗列，方法或者设备也可能包含其它的步骤或元素。
本申请中使用了流程图用来说明根据本申请的实施例的系统所执行的操作。应当理解的是，前面或后面操作不一定按照顺序来精确地执行。相反，可以按照倒序或同时处理各个步骤。同时，也可以将其他操作添加到这些过程中，或从这些过程移除某一步或数步操作。
在进行动物扫描成像时，待扫描动物会放置于扫描舱内，由相应的扫描设备(例如，CT设备、PET设备、MRI设备等)对其进行扫描成像。在此过程中，一般会对待扫描动物的呼吸信号和心电信号进行测量。
在一些实施例中，应用于动物扫描成像的扫描舱对待扫描动物的生理状态进行的监控为接触式生理监控，即需要将相应的检测装置与待扫描动物直接接触才能测量到相应的生理状态信号，然后将生理状态信号通过传输线缆传输至扫描舱外，以实现对待扫描动物的生理监控。例如，在对待扫描动物的体温进行监控时，可以将直肠温度传感器插入待扫描动物的肛门内以进行体温测量。又例如，在对待扫描动物的呼吸进行监控时，可以将呼吸垫设置于待扫描动物的腹部，通过待扫描动物的腹部运动压迫呼吸垫内的气体流出以产生呼吸信号。再例如，在对待扫描动物的心电进行监控时，也可以通过与待扫描动物直接接触来进行电极信号采集。在一些实施例中，与待扫描动物直接接触来进行电极信号采集可以包括有创式和无创式。其中，有创式是通过电极针穿刺于待扫描动物皮下进行电极信号采集，无创式是通过电极贴贴附于待扫描动物的表皮进行电极信号采集。通过采用接触式生理监控的方式来测量待扫描动物的生理状态信号，一般需要较长的准备时间，在准备过程中处于浅麻醉状态的待扫描动物可能已经苏醒，因而对实验人员的操作速度提出了较高的要求，而且检测装置与待扫描动物直接接触，操作也比较麻烦，并且容易影响待扫描动物的麻醉状态。另外，由于不同种类、大小等动物所适配的扫描舱的规格不同，为了提高扫描过程的便捷程度，用于实现动物扫描成像的扫描成像系统中的扫描舱为可更换式，如果采用接触式生理监控的方式，则会导致用于传输生理状态信号的传输线缆需要经过多次转接，转接传输的过程中容易造成信号的衰减，使得信号测量的准确性较差。
在实际操作中，由于用于实现动物扫描成像的扫描成像系统中的扫描舱为可更换式，为了便于将扫描舱更换以适配相应的待扫描动物，在扫描前则需要对扫描舱进行识别。在一些实施例中，可以通过人为判断获取扫描舱的相关特征信息(例如，外形、标识等)，以此确定对应的扫描舱，但人为判断往往会出现偏差，而导致识别结果不正确。在一些实施例中，可以通过采集到的视觉信息、传感器信息或者电子标签信息等来获取扫描舱的相关特征信息，进一步基于该相关特征信息确定对应的扫描舱。例如，通过获取扫描舱的图像特征并进行分类，以获取扫描舱的识别结果。又例如，可以基于射频信号与读卡器进行通信的方式，通过读卡器扫描电子标签的内容来确定对应的扫描舱。然而，这种扫描舱的识别方式一般需要借助复杂的传感设备、计算设备和算法来完成，导致扫描舱的识别成本较高并且识别效率低，还存在误判风险。
本说明书实施例提供了一种扫描舱、扫描舱的识别方法以及扫描成像系统。本说明书实施例提供的扫描舱通过在舱体上设置了一系列功能组件(例如，心电检测装置、摄像器件、测温仪器等)可以实现对待扫描动物的非接触式生理监控，即心电检测装置、摄像器件、测温仪器等检测装置不用与待扫描动物直接接触便能对其生理状态信号(例如，心电信号、呼吸信号、体温等)进行测量，不仅可以缩短前期准备时间，操作简便，提高实验效率，而且不会对待扫描动物的麻醉产生影响，另外，测量到的生理状态信号可以通过无线传输的方式传送到计算机端，减少了信号中转传输过程中的衰减，同时也避免了传输线缆多次转接，降低了扫描舱结构的复杂度。除此之外，本说明书实施例提 供的扫描舱在舱体内也设置了一系列功能组件(例如，头部固定组件、温度调节器、麻醉管路等)，来保证待扫描动物在扫描舱内的固定、保温，使其处于麻醉状态并生理特征保持稳定。本说明书实施例提供的扫描舱识别方法，通过获取扫描舱的编码信息，然后基于扫描舱的编码信息和预设编码信息可以确定扫描舱的规格参数，无需借助复杂的传感设备(例如，复杂的视觉系统)和算法(例如，复杂的图像处理算法)，便能够解决扫描舱识别成本高、识别效率低的技术问题，并且能够提高扫描舱的识别准确性。本说明书实施例提供的扫描成像系统通过采用本说明书实施例提供的扫描舱和/或应用本说明书实施例提供的扫描舱的识别方法，能够降低系统的复杂度，提高在扫描前根据待扫描动物更换扫描舱的效率，便于实验人员操作，提高动物扫描成像整个过程的流畅性。

在一些实施例中，I/O模块的若干I/O接口的状态值可以作为扫描舱的编码信息。在一些实施例中，若干I/O接口的状态值可以包括若干I/O接口中的每个I/O接口的状态值以及若干I/O接口的位置顺序。在一些实施例中，若干I/O接口中的每个I/O接口的状态值可以按照若干I/O接口的位置顺序进行排列组合，以形成若干I/O接口的状态值。在一些实施例中，基于I/O模块不同的I/O接口，可以确定不同的状态值，即若干I/O接口中的每个I/O接口的状态值可以不同。在一些实施例中，不同的I/O接口可以输出不同的数值，以作为I/O接口对应的状态值。在一些实施例中I/O接口的状态值可以用I/O接口的电平状态来表示，例如，I/O接口的电平状态可以包括高电平状态和低电平状态。在一些实施例中，I/O接口的电平状态可以采用布尔量(即二进制代码)来表示。其中，高电平状态可以用“1”表示，低电平状态可以用“0”表示。在一些实施例中，在一些实施例中，若干I/O接口的位置顺序可以是固定的或默认的。在一些实施例中，若干I/O接口的位置顺序可以根据用于读取若干I/O接口的状态值的引脚的设置位置预先确定。作为示例性说明，扫描舱上的连接器母头上设置有若干I/O接口，扫描舱支撑臂上的连接器公头上对应设置用于读取若干I/O接口中每个I/O接口的状态值的若干引脚，其中，若干I/O接口的位置顺序则可以根据对应的连接器公头上的引脚的设置位置预先确定。在一些实施例中，当扫描成像系统对扫描舱进行更换时，需要重新获取扫描舱的I/O模块中若干I/O接口的位置顺序。
在一些实施例中，通过计算机系统读取到I/O模块的若干I/O接口的状态值(即扫描舱的编码信息)后，将该状态值与预先记录在计算机系统中的I/O编码值(即预设编码信息)进行匹配，进而获取扫描舱对应的规格参数。
本说明书实施例中的扫描舱包括I/O模块，扫描舱的编码信息包括I/O模块的若干I/O接口的状态值。通过获取I/O模块的若干I/O接口的状态值以获取扫描舱的编码信息，结构简单且计算成本低，易于实现数字化编码，进而提高了扫描舱的识别效率。
在一些实施例中，I/O模块包括若干I/O接口，获取扫描舱的编码信息可以包括：
基于若干I/O接口的接线方式获取与接线方式对应的I/O接口的状态值。
在一些实施例中，获取模块201可以通过I/O模块的若干I/O接口的接线方式，确定I/O接口的状态值。其中，不同接线方式下的若干I/O接口，其状态值也不相同。在一些实施例中，若干I/O接口的接线方式可以是指若干I/O接口中参与接线的I/O接口的数量及其位置顺序。

作为示例性说明，如图5所示，I/O模块可以包括编号分别为1-14的14个I/O接口，其中，I/O接口的编号可以代表I/O接口的位置顺序。14个I/O接口在不同接线方式下所对应的状态值也不相同。例如，当对编号为1、11、14的I/O接口进行连接时，可以将“01 11 14”或者对应的二进制数“0001 1011 1101”作为该接线方式对应的状态值，又例如，当对编号为1、2、10、14的I/O接口进行连接时，可以将“01 02 10 14”或者对应的二进制数“0001 0010 1010 1100”作为该接线方式对应的状态值。
在一些实施例中，当若干I/O接口采用某一种接线方式时，可以将若干接口的电平状态的组合作为与该接线方式对应的状态值。其中，参与接线的I/O接口的电平状态可以为高电平状态，用“1”表示，未参与接线的I/O接口的电平状态为低电平状态，用“0”表示。例如，当编号为1、11、14的I/O接口进行连接时，可以将编号1-14的I/O接口的电平状态进行组合为“10000000001001”作为该接线方式对应的状态值。又例如，当对编号为1、2、10、14的I/O接口进行连接时，可以将“11000000010001”作为该接线方式的状态值。
在一些实施例中，若干I/O接口的接线方式的数量可以与若干I/O接口的I/O接口的总数量和若干I/O接口参与接线的I/O接口的数量(或者与用于读取I/O接口状态值的引脚数量)相关。可以理解的是，通过修改若干I/O接口的接线方式，例如，调整I/O接口的总数量和/或用于读取I/O接口状态值的引脚数量，可以为若干I/O接口设定不同的状态值。例如，如图5所示，当用于读取I/O接口的状态值的引脚数量为3时，14个I/O接口存在14×13×12种接线方式。又例如，当引脚数量为4时，14个I/O接口存在14×13×12×11种接线方式。需要说明的是，图5所示的I/O模块的I/O接口的数量以及参与接线的I/O接口数量仅作为示例，并无意于对此进行限制。在一些实施例中，I/O模块中的I/O接口的数量以及参与接线的I/O接口数量可以根据实际需要(有多少不同类别或规格的扫描舱)进行设置。
在实际应用场景下，选择预设数量的接线方式，并进一步设定对应的状态值，然后将状态值作为预设编码信息关联到对应的扫描舱，然后便可以基于扫描舱的编码信息以及预设编码信息确定扫描舱的规格参数。
本说明书实施例基于若干I/O接口的接线方式获取与接线方式对应的若干I/O接口的状态值。通过若干I/O接口的接线方式确定I/O接口的状态值，作为扫描舱的编码信息，无需添加额外的状态值获取模块，可基于实际需要选择多种接线方式，并且接线方式容易区分和辨别，降低了扫描舱的识别成本。

在一些实施例中，扫描舱的规格参数可以对应一种编码信息和/或预设编码信息。在一些实施例中，扫描舱的规格参数可以包括扫描舱的形状、尺寸、扫描强度、承重(即能够承载扫描对象的重量)以及扫描成像系统包括该扫描舱时支持的最大分辨率等或其组合。
在一些实施例中，在获取模块201获取到扫描舱的编码信息后，确定模块202可以基于扫描舱的编码信息直接确定扫描舱的规格参数。在一些实施例中，扫描舱的编 码信息可以是包括有扫描舱的规格参数相关信息的编码(例如，ASCII编码、Unicode、UTF-8、UTF-16等)，确定模块202可以利用相应的解码算法对扫描舱的编码信息进行解码，以此获取扫描舱的规格参数。
在一些实施例中，确定模块202可以基于编码信息和预设编码信息，确定扫描舱的规格参数。进一步地，确定模块202可以判断数据库中是否存在与扫描舱的编码信息对应的预设编码信息，每个预设编码信息与单个扫描舱的规格参数相对应。若数据库中存在与扫描舱的编码信息对应的预设编码信息，确定模块202则可以从数据库中获取与预设编码信息对应的扫描舱的规格参数。关于确定模块202是如何基于编码信息和预设编码信息确定扫描舱的规格参数的更多描述可以参考方法600的相关描述。
在一些实施例中，确定模块202可以基于扫描舱的图像直接确定扫描舱的规格参数。作为示例性说明，确定模块202可以通过图像处理算法扫描舱的图像进行特征识别，以获取扫描舱的图像特征，然后基于扫描舱的图像特征确定扫描舱的规格参数。
图6是根据本说明书一些实施例所示的扫描舱的识别方法的示例性流程图。如图6所示，方法600可以包括以下步骤：
步骤610，获取扫描舱的编码信息。步骤610可以由获取模块201执行。关于步骤610的更多描述可以参考方法400中的步骤410相关描述，在此不再赘述。
步骤620，判断数据库中是否存在与扫描舱的编码信息对应的预设编码信息。步骤620可以由确定模块202执行。
在一些实施例中，获取模块201获取扫描舱的编码信息后，确定模块202可以在数据库中进行检索，以判断是否存在与扫描舱的编码信息对应的预设编码信息。其中，预设编码信息为预先设定的、与扫描舱的类别相对应的编码信息，用于标识该类别的扫描舱。进一步地，每个预设编码信息均与单个扫描舱的规格参数相对应。在一些实施例中，每个预设编码信息以及与该预设编码信息对应的扫描舱的规格参数可以预先存储于数据库中，以用于后续对扫描舱的编码信息在数据库中进行预设编码信息的检索和匹配。
步骤630，若存在，则从数据库中获取与预设编码信息对应的扫描舱的规格参数。步骤630可以由确定模块202执行。
在一些实施例中，若确定模块202在数据库中检索到与扫描舱的编码信息对应的的预设编码信息，则可以从该数据库中获取该预设编码信息对应的扫描舱的规格参数。可以理解的是，该预设编码信息对应的扫描舱的规格参数即为所获取的编码信息对应的扫描舱的规格参数。在一些实施例中，基于预设编码信息对应的扫描舱的规格参数，可以确定扫描成像系统对扫描对象的扫描方式、扫描步骤、扫描参数等。在一些实施例中，扫描成像系统对扫描对象的扫描方式可以和扫描成像系统中的扫描设备相关。例如，当扫描设备为CT设备时，扫描成像系统对扫描对象的扫描方式可以包括定位向扫描、轴向断层扫描、连续扫描、螺旋扫描等。在一些实施例中，扫描成像系统对扫描对象的扫描步骤可以是指扫描成像系统的操作流程。在一些实施例中，扫描成像系统对扫描的扫描参数可以包括扫描成像系统的扫描强度(例如，放射剂量、管电流等)、分辨率、视场、扫描模态等或其组合。在一些实施例中，扫描模态可以包括CT成像、MR成像、PET成像、SPECT成像、超声成像、可见光成像等。
在一些实施例中，若确定模块202在数据库中没有检索到与编码信息对应的预设编码信息，此时至少存在两种可能情形：第一，扫描成像系统中引入了新的扫描舱，即该扫描舱没有设置预设编码信息存储于数据库中，数据库中也没有该扫描舱的规格参数，此时确定模块202可以输出提示信息，例如，向终端输出提示信息，以提示用户对该扫描舱的预设编码信息进行设置，并将设置的预设编码信息以及该扫描舱的规格参数保存至数据库；第二，扫描成像系统出现故障，导致获取模块201无法准确获取或者匹 配扫描舱的编码信息，此时扫描成像系统可以输出故障信息，以提示用户对系统故障进行处理。
本说明书实施例提供的扫描舱的识别方法通过获取扫描舱的编码信息，判断数据库中是否存在与编码信息对应的预设编码信息，每个预设编码信息均与单个扫描舱的规格参数相对应；若存在，则从数据库中获取与预设编码信息对应的扫描舱的规格参数，以作为扫描成像系统中的扫描舱的规格参数。通过扫描舱的编码信息确定扫描舱的规格参数，可以解决扫描成像系统中扫描舱的识别成本较高并且识别效率低，还存在误判风险的技术问题，无需借助复杂的设备且识别方法简单，降低了扫描舱的识别成本，提高了扫描舱的识别效率。
在一些实施例中，判断数据库中是否存在与编码信息对应的预设编码信息之前还可以包括：建立预设编码信息与扫描舱的规格参数的对应关系，然后将预设编码信息与扫描舱的规格参数的对应关系保存至数据库。
在一些实施例中，确定模块202可以确定扫描舱与预设编码信息的对应关系，进而将该扫描舱的规格参数关联到该预设编码信息，建立预设编码信息与扫描舱的规格参数的对应关系，并将该对应关系保存到数据库。在一些实施例中，确定模块202可以为每一种类型的扫描舱分配预设编码信息，以用于标识该类型的扫描舱，然后获取该类型的扫描舱的规格参数，并建立与预设编码信息的对应关系；将预设编码信息以及对应的扫描舱的规格参数保存至同一存储单元(例如，图1所示的存储设备150或图2所示的存储器134)，以方便直接基于预设编码信息查询对应的扫描舱的规格参数。
在一些实施例中，本说明书实施例提供扫描舱的识别方法还可以包括基于扫描舱的规格参数确定扫描舱对应的扫描参数。
在一些实施例中，在确定模块202获取扫描舱的规格参数后，确定模块202可以进一步根据扫描舱的规格参数确定扫描舱对应的扫描参数。可以理解的是，由于扫描对象的尺寸、姿态等各不相同，因此扫描舱的规格参数也不同，针对不同的扫描对象以及扫描舱，需要扫描成像系统以不同的扫描参数对扫描对象进行扫描，以达到最佳的扫描效果。具体地，对不同的扫描对象进行不同扫描强度、分辨率、扫描模态等的扫描，以获取不同扫描强度和/或分辨率下的CT图像、PET图像、SPECT图像等不同模态下的扫描图像。
在一些实施例中，确定模块202也可以直接基于扫描舱的编码信息以及预设编码信息确定扫描舱对应的扫描参数。例如，确定模块202可以直接基于编码信息确定与编码信息对应的扫描舱对应的扫描参数。又例如，确定模块202可以判断数据库中是否存在与扫描舱编码信息对应的预设编码信息，若存在，然后从数据库中获取与预设编码信息对应的扫描舱的扫描参数。在一些实施例中，确定扫描舱的规格参数和扫描参数可以同时进行按照顺序进行。在一些实施例中，扫描舱对应的扫描参数可以包括与扫描舱对应的分辨率阈值。
在一些实施例中，本说明书实施例提供的扫描舱的识别方法还可以包括获取通过终端(例如，终端130)输入的分辨率，并判断该分辨率的数值是否小于分辨率阈值，若小于则输出提示信息，以提示重新输入分辨率或者更换扫描舱。其中，分辨率阈值可以是指扫描成像系统中的扫描成像装置(例如，图1所示的扫描成像装置110)所支持的最大分辨率的数值。在一些实施例中，扫描成像装置的分辨率阈值即可看作是具有其的扫描成像系统的分辨率阈值。在一些实施例中，扫描成像系统可以根据通过终端输入的分辨率设置其在扫描过程中的分辨率，所获取的扫描图像中的分辨率则为该分辨率。其中，扫描图像中的分辨率的数值越小，扫描图像中的分辨率就越高，也即是说，当扫描成像系统以通过终端输入的分辨率进行扫描成像时，该分辨率的数值越小，所获取的 扫描图像中的分辨率就越高。进一步地，当扫描成像系统以某一分辨率进行扫描成像时获取到了最大分辨率的扫描图像，该分辨率的数值则为扫描成像系统的分辨率阈值。
在一些实施例中，在对扫描对象进行扫描前，确定模块202中的分辨率获取子模块可以接收并获取通过终端输入的分辨率，然后由判断子模块判断该分辨率的数值是否小于分辨率阈值，即该分辨率是否超过扫描成像系统所支持的最大分辨率。若该分辨率的数值小于分辨率阈值，即该分辨率超过最大分辨率时，输出子模块则可以输出提示信息，提示信息可以发送至终端并在终端上进行显示，以用于提示用户重新输入分辨率，或者更换不同规格参数的扫描舱。在一些实施例中，扫描成像系统可以根据分辨率阈值设置通过终端输入的分辨率的数值的范围，例如，通过终端输入的分辨率的数值的范围可以大于或等于分辨率阈值，这样可以使得通过终端一次性输入的分辨率的数值即可大于分辨率阈值。
在一些实施例中，在获取通过终端输入的分辨率之前，可以先对扫描成像系统的分辨率阈值进行确定。具体地，扫描成像系统的分辨率阈值至少与其包括的扫描舱和扫描设备相关。作为示例性说明，扫描成像系统中的扫描设备可以是CT设备，CT设备可以包括扫描架和设置在扫描架上的球管和探测器。其中，球管可以包括X射线出射窗和滤过器，球管可以从X射线出射窗发射出X射线经过滤过器穿透扫描对象的某个部位一定厚度的层面以被探测器所接收。进一步地，分辨率阈值可以基于CT设备的X射线出射窗到探测器的第一距离、X射线出射窗到滤过器的第二距离以及探测器像素点的尺寸参数确定。其中，X射线出射窗到滤过器的第二距离可以由X射线出射窗到扫描舱旋转中心的第三距离与扫描舱的外径所确定。通过获取扫描设备的X射线出射窗到探测器的第一距离、X射线出射窗到滤过器的第二距离、X射线出射窗到扫描舱旋转中心的第三距离以及探测器像素点的尺寸参数，基于第一距离、第二距离、第三距离以及像素点的尺寸参数便能确定扫描成像系统的分辨率阈值。在一些实施例中，通过确定模块202来确定扫描舱的规格参数，可以确定扫描舱的外径。
图7是根据本说明书一些实施例所示的扫描成像装置的几何示意图。如图7所示，X射线出射窗到探测器的第一距离为SDD，X射线出射窗到滤过器的第二距离为SFD，X射线出射窗到扫描舱旋转中心的第三距离为SID，扫描舱的外径为D，探测器像素点尺寸为dpixelSize。分辨率M与第一距离、所述第二距离以及探测器像素点的尺寸满足如下关系：
Figure PCTCN2022102032-appb-000001
其中，探测器像素点尺寸dpixelSize为探测器固定参数，第一距离为SDD为固定值，在扫描成像装置(或扫描成像系统)达到分辨率阈值时满足几何条件：
Figure PCTCN2022102032-appb-000002
此时扫描舱处于与滤过器接触的临界点，在该几何条件下系统达到分辨率阈值，即分辨率的数值可达到的最小值，分辨率阈值M Isotropic为：
Figure PCTCN2022102032-appb-000003
扫描成像系统在扫描时的分辨率的数值应满足：
Mt≥M Isotropic
其中，Mt为扫描过程中可以设置的分辨率的数值。可以理解的是，当SID越小时，动物扫描断层接受到的射线粒子越多，扫描图像中的分辨率越高，其对应的分辨率的数值越小。当扫描舱处于与滤过器接触的临界点时，扫描断层到X射线出射窗的距 离达到最小值
Figure PCTCN2022102032-appb-000004
此时分辨率的数值达到最小值M Isotropic；当扫描舱处于与探测器接触的临界点时，此时扫描断层到X射线出射窗的距离达到最大值SDD，此时分辨率的数值达到最大。若在扫描过程中，扫描成像系统获取通过终端输入的分辨率的数值小于M Isotropic，即通过终端输入的分辨率超过最高分辨率，则系统禁止进行SID调节，从而避免扫描舱和滤过器发生碰撞，实现扫描成像系统的主动防碰撞，保护系统安全。在一些实施例中，通过确定扫描成像系统的分辨率阈值，可以对扫描成像系统的分辨率的数值的范围进行限定，根据扫描舱外径计算得到的分辨率阈值设置通过终端输入的分辨率的数值的选择范围，使通过终端输入的分辨率的数值的选择范围不小于分辨率阈值。
本说明书一些实施例通过获取通过终端输入的分辨率，并判断分辨率的数值是否小于分辨率阈值，若小于则输出提示信息，以提示重新输入分辨率或者更换扫描舱。通过将分辨率与分辨率阈值进行比较，以避免系统发生安全事故，并输出提示信息，提高了扫描成像系统的安全性。
下面将结合附图对本说明书实施例中扫描成像系统中的扫描成像装置进行详细描述。
图8是根据本说明书一些实施例的扫描成像装置的结构示意图，图9是根据本说明书一些实施例所示的扫描舱与扫描舱支撑臂的结构示意图，图10-图11是根据本说明书一些实施例的扫描舱支撑臂的结构示意图，图12是根据本说明书一些实施例所示的扫描舱的结构示意图。具体地，如图8所示，扫描成像装置110可包括扫描舱111、扫描床112、扫描舱支撑臂113、舱罩114、扫描设备115以及扫描对象116。其中，扫描床112具有进给机构，能够带动扫描舱113沿图8所示的X方向轴向进给；扫描舱支撑臂113固定于扫描床112的进给机构上，扫描舱支撑臂113上的连接器公头与扫描舱111上的连接器母头连接可以使得扫描舱支撑臂113和扫描舱111形成可更换的快拆连接结构，能够进行快速插拔，以便于根据不同的扫描对象116选取合适的扫描舱111。其中，扫描对象116位于扫描舱111内，通过扫描床112的进给机构进给到扫描设备115中进行扫描成像，获取扫描图像如CT图像、PET图像，SPECT图像以及不同模态的组合成像等。
在一些实施例中，如图8-图12所示，扫描舱111以及扫描舱支撑臂113组成的一体式结构可以包括扫描舱支撑臂113、扫描舱111、隔板117以及热风接口118。其中，扫描舱支撑臂113上固定有气体以及气信号第一传输管路21、电信号传输连接器公头22、对外气体以及气信号连接器23以及对外信号连接器24；扫描舱113上固定有气体以及气信号第二传输管路31、电信号传输连接器母头32、舱内气体以及气信号连接器33以及舱内电信号连接器34。进一步地，气体以及气信号第一传输管路21与气体以及气信号第二传输管路31连接，电信号传输连接器公头22与电信号传输连接器母头32连接。在一些实施例中，隔板117与扫描舱111之间有一定的空间，用于接收热风，并对扫描舱111内的温度进行控制。
在一些实施例中，通过电信号传输连接器公头22与电信号传输连接器母头32之间连接可以实现将扫描舱111内的舱内电信号的传输。在一些实施例中，舱内电信号主要可以包括活体样本(即扫描对象116)的ECG信号(即心电信号)和体温信号、扫描舱规格参数、扫描舱内温度信息等或其组合。作为示例性说明，活体样本的ECG信号以及体温信号经小动物生理监控单元采集传感器采集到后，经过电信号传输连接器母头32与电信号传输连接器公头22，最后通过对外信号连接器24传到外部信号处理模块进行信号的处理。
在一些实施例中，通过气体以及气信号第一传输管路21与气体以及气信号第二传输管路31连接可以实现扫描舱111的舱内气体和气信号的传输。在一些实施例中， 舱内气体主要可以包括麻醉气体以及可调节温度暖风，气信号主要包括呼吸信号。作为示例性说明，可调节温度暖风依次经过气体以及气信号第一传输管路21、气体以及气信号第二传输管路31，最终通过热风接口118进入到隔板117与扫描舱111之间的空间，实现对舱内温度的调节，同时避免热风对扫描舱111内扫描对象116的直吹，导致对扫描对象116的损伤。呼吸信号经过采集后，依次经过舱内气体以及气信号连接器33、气体以及气信号第二传输管路31、气体以及气信号第一传输管路21、对外气体以及气信号连接器23，最终发送至外部信号处理模块。
在一些实施例中，针对不同规格参数的扫描舱以及不同扫描参数的扫描成像设备，通过连接器公头(例如电信号传输连接器公头22)与连接器母头(例如，电信号传输连接器母头32)的连接方式(例如，若干I/O接口的接线方式)可以确定其对应的扫描舱的规格参数以及其他信号。
图13是根据本说明书一些实施例所示的连接器接口的结构示意图。
如图13所示，连接器接口可以包括温度控制单元接口、I/O采集模块接口、生理信号分析模块接口、舱内温度传感器接口、ECG传感器接口以及直肠温度传感器接口。具体地，温度控制单元可以用于对扫描舱内的实时温度进行控制；I/O采集模块可以用于获取电信号传输连接器母头32上若干I/O接口的状态值，并基于该状态值(即编码信息)确定扫描舱的类别(或规格参数)；生理信号分析模块可以用于传输扫描对象的生理信号并对生理信号进行分析；舱内温度传感器用于获取扫描舱内的实时温度，并将该实时温度转化为电信号传输给温度控制单元；ECG传感器可以用于获取扫描对象的ECG信号以对扫描对象的健康状况进行判断；直肠温度传感器可以用于用户获取扫描对象的直肠温度。基于不同的连接方式选择不同的接口，以实现温度控制、若干I/O接口的状态值采集、生理信号分析等功能。
本说明书实施例提供的扫描成像系统通过将扫描舱设置成可更换式，然后应用本说明书实施例提供的扫描舱的识别方法，通过获取扫描舱的预设信息，然后基于预设信息和编码信息确定扫描舱的规格参数以及扫描参数，实现对扫描舱的准确识别，降低识别成本，提高识别效率。
另外，本说明书实施例提供的扫描成像系统还可以对扫描对象的生理状态进行监控。在一些实施例中，本说明书实施例提供的扫描成像系统可以通过扫描舱实现对扫描对象的生理状态(例如，体温、呼吸、心电图等)监控。在一些实施例中，扫描舱对扫描对象的生理状态监控可以为接触式生理监控。具体地，扫描舱上设置有用于检测扫描对象生理状态的检测装置，该检测装置需要与扫描对象直接接触才能检测到相应的生理状态信号，然后将生理状态信号通过传输线缆传输至扫描舱外，以实现对待扫描动物的生理监控。例如，在对扫描对象的体温进行监控时，将直肠温度传感器插入扫描对象的肛门内以进行体温测量。又例如，在对扫描对象的呼吸进行监控时，将呼吸垫设置于扫描对象的腹部，通过扫描对象的腹部运动压迫呼吸垫内的气体流出以产生呼吸信号。再例如，在扫描对象的心电进行监控时，将电极针穿刺与扫描对象皮下或将电极贴贴附于扫描对象的皮肤上来进行电极信号采集。扫描舱通过采用接触式生理监控的方式来测量扫描对象的生理状态信号，一般需要较长的前期准备时间，在准备过程中处于浅麻醉状态的扫描对象可能已经苏醒，因而对实验人员的操作速度提出了较高的要求，而且检测装置与扫描对象直接接触，操作也比较麻烦，并且容易影响扫描对象的麻醉状态。另外，由于不同种类、大小等扫描对象所适配的扫描舱的规格不同，为了提高扫描过程的便捷程度，用于实现动物扫描成像的扫描成像系统中的扫描舱为可更换式，如果采用接触式生理监控的方式，则会导致用于传输生理状态信号的传输线缆需要经过多次转接，转接传输的过程中容易造成信号的衰减，使得信号测量的准确性较差。本说明书实施例 提供了一种扫描舱，该扫描舱的舱体上设置了一系列功能组件，功能组件至少可以包括心电检测装置、摄像器件和测温仪器。其中，该心电检测装置可以实现对扫描对象的心电图的非接触式监控，该摄像器件可以实现对扫描对象的呼吸状态和/或麻醉状态的非接触式监控，该测温仪器可以实现对扫描对象的体温的非接触式生理监控，从而缩短了前期准备时间，操作方便，不会对扫描对象的麻醉造成影响。
下面将结合附图对本说明书实施例提供的扫描舱进行详细描述。
图14是根据本说明书一些实施例所示的扫描舱的结构示意图。图15是根据本说明书一些实施例所示的本体的结构示意图。图16是根据本说明书一些实施例所示的舱体的结构示意图。图17是根据本说明书一些实施例所示的容性耦合电级检测扫描对象心电图时的工作原理图。
如图14所示，扫描舱111可以包括用于放置扫描对象的舱体1以及集成在舱体1上的功能组件(未在图14中示出)。在一些实施例中，功能组件可以包括心电检测装置、摄像器件、测温仪器、温度调节器、连接器母头、面罩、麻醉管路、头部固定组件等或其组合。其中，心电检测装置可以实现对扫描对象的心电图的非接触式监控，摄像器件可以实现对扫描对象的呼吸状态和/或麻醉状态的非接触式监控，测温仪器可以实现对扫描对象的体温的非接触式生理监控，从而缩短了前期准备时间，操作方便，不会对扫描对象的麻醉造成影响。连接器母头可以用于在扫描舱和扫描成像系统中的其他部件(例如，终端、处理设备等)之间传输信息或信号。具体地，连接器母头可以用于将扫描舱的编码信息扫描成像系统中的其他部件，以便于对扫描舱进行识别，并且还能将扫描对象的生理状态信号传输至扫描成像系统的其他部件，以便于根据扫描对象的生理状态信号进行分析，以达到监控扫描对象的生理状态的目的。温度调节器可以用于调节扫描对象所在区域的温度，避免扫描对象进入麻醉状态后体温下降而导致扫描对象死亡。面罩可以用于罩盖住扫描对象的嘴部，以固定扫描对象的嘴部，麻醉管路可以向面罩内输送麻醉气体，以对扫描对象进行麻醉。头部固定组件可以对扫描对象的耳部、牙部和/或嘴部进行固定。
在一些实施例中，如图14所示，舱体1可以包括本体10和舱盖20。其中，舱盖20可拆卸地安装于本体10上，以便于在扫描舱前期工作时，可先将舱盖20从本体10上取下，再将扫描对象放入至本体10内，然后再盖合舱盖20。可以理解的是，功能组件集成在舱体1上并不单指功能组件集成于舱体1的外部，也可以是指功能组件集成于舱体1的内部。
在一些实施例中，集成在舱体上的功能组件可以用于扫描舱111和扫描成像系统中的其他部件(例如，图1所示的扫描舱支撑臂113、处理设备150等)进行电连接，以便于确定扫描舱111的规格参数以及其他信号(例如，位于扫描舱111内的扫描对象的生理信号，例如，心电信号、呼吸信号、体温信号、ECG信号等)。
在一些实施例中，集成在扫描舱上的功能组件可以包括连接器母头(例如，图12所示的电信号传输连接器母头32)，连接器母头可以用于与扫描成像系统的扫描舱支撑臂(例如，扫描舱支撑臂113)上的连接器公头(例如，图10所示的电信号传输连接器公头22)连接，连接器母头与连接器公头连接后能生成扫描舱的编码信息；根据编码信息能识别扫描舱的规格参数和/或扫描参数。关于如何根据编码信息识别扫描舱的规格参数和/或扫描参数的更多描述可以参考本说明书实施例提供的扫描舱的识别方法的相关描述，在此不再赘述。
在一些实施例中，舱体1上装有连接器母头，可以用于与扫描成像系统的扫描舱支撑臂上的连接器公头连接，以形成可更换的快拆连接结构。具体的，包括连接器公头和连接器母头的连接器可以采用POGO连接器。其中，该连接器公头可以为弹簧顶 针结构，母头可以为金属触点结构，当扫描舱111安装在扫描舱支撑臂上后弹簧顶针紧压在金属触点上，从而实现电信号的可靠传输。可以理解的是，上述POGO连接器仅仅作为示例，并无意于对其进行限制。在一些实施例中，其他类型的连接器如HDMI接口连接器、USB接口连接器等亦在本说明书实施例的连接器的保护范围内。关于连接器母头以及连接器公头的更多描述可以在本说明书其他地方(例如，图8-13及其相关描述)找到，在此不再赘述。
在一些实施例中，扫描舱111上的连接器母头与扫描舱支撑臂上的连接器公头连接后，可以生成扫描舱的编码信息，基于该编码信息可以对扫描舱111进行识别，以获取扫描舱对应的规格参数和/或扫描参数。具体的，可以基于连接器公头与连接器母头的连接方式(例如，连接器母头上若干I/O接口的接线方式)，确定对应的编码信息。关于如何基于连接器公头和连接器母头的连接方式确定对应的编码信息可以在本说明书其他地方(例如，图4及其相关描述)找到，在此不再赘述。
本说明书实施例中的扫描舱上的功能组件包括连接器母头，连接器母头用于与扫描成像系统的扫描舱支撑臂上的连接器公头连接，连接器母头与连接器公头连接后能生成扫描舱的编码信息；根据编码信息能识别扫描舱的规格参数和/或扫描参数。通过连接器公头与连接器母头进行连接，实现了稳定可靠的电信号传输，并且基于连接器的连接方式可以直接确定扫描舱的编码信息，无需通过第三方设备生成扫描舱的编码信息，提高了扫描舱的识别效率。
在一些实施例中，设置于舱体1上的功能组件可以用于对位于扫描舱111内的扫描对象的生理数据(例如，心电图、体温等)的监测，并可将测得的监测数据发送给控制电脑(例如，扫描成像系统100中的控制器、终端130或处理设备140等)。
在一些实施例中，设置于舱体1上的功能组件可以包括心电检测装置，心电检测装置可以用于对置于舱体1内的扫描对象进行心电检测，以对扫描对象的心电图进行监控。具体地，心电检测装置可以固定在本体10上，使得心电检测装置可以集成在舱体1上，以此实现扫描舱111工作(例如，对扫描舱111内的扫描对象进行扫描成像)时对扫描对象的心电图的非接触监控，不必通过电极针或电极贴与扫描对象接触来对扫描对象进行信号采集以实现对扫描对象的心电图监控，操作人员也就不必将电极针穿刺扫描对象皮下或将电极贴贴附于扫描对象的皮肤表面上，不仅可以缩短前期准备时间，而且操作简便，对扫描对象的麻醉不产生影响。
在一些实施例中，如图15和17所示，心电检测装置可以包括电容耦合器40。电容耦合器40能够与扫描对象的四肢的皮肤101配合并产生电容耦合，以此具体实现该心电检测装置的结构设置，使得扫描舱111能够通过电容耦合器40与动物上四肢皮肤101之间的电容耦合作用，以此实现扫描舱111对扫描对象的心电图的非接触监控。
在一些实施例中，如图15所示，舱体1上可以设置有电路板30，心电检测装置上中的每个电容耦合器40可以分别与电路板30信号连接。具体地，每个电容耦合器40可通过线缆及接口与电路板30进行信号连接，每个电容耦合器40可以测得所述皮肤101表面的电信号并发送至电路板30上。需要说明的是，电路板30可以包括但不限于数据采集模块，用于收集每个电容耦合器40测得皮肤101表面的电信号。在一些实施例中，电路板30在接受电容耦合器40传送的电信号后还能够对其进行滤波、放大处理后离散化，然后将其通过有线或者无线的方式发送给控制电脑。
在一些实施例中，扫描舱111能够通过电容耦合器40与扫描对象的四肢的皮肤101之间的电容耦合作用，使皮肤101的电信号能够通过电容耦合器40传递至电路板30上，以此实现扫描舱111对扫描对象的心电图的非接触监控，不仅可以缩短前期准备时间，而且只需将扫描对象的四肢对应放置于电容耦合器40所在的位置，操作简便， 对扫描对象的麻醉不产生影响。
在一些实施例中，如图17所示，电容耦合器40上设置有容性耦合电级41，容性耦合电级41可以与皮肤101形成间隙，以使容性耦合电极41与对应的皮肤101配合时能够产生电容耦合，以此具体实现该电容耦合器40与皮肤101之间产生的电容耦合。
在一些实施例中，将扫描对象的四肢设置于电容耦合器40上时，容性耦合电极41与对应的皮肤101之间的空气以及扫描对象的毛发可以共同构成一组电容。其中，皮肤101和容性耦合电极41可以作为电容的传导体，空气和扫描对象的毛发可以作为绝缘体，以此共同构成电容的表达式为：C＝∏S/d。其中，∏为介电常数，S为容性耦合电级41的面积，d为容性耦合电级41与皮肤101之间的间距，因此电容值与容性耦合电级41和皮肤101之间的距离成反比。进一步地，扫描对象的皮肤101的电信号可以通过电容耦合作用传递到容性耦合电级41，并由容性耦合电级41输送至电路板30，然后将该电信号进行差分运算即可获得心电信号，以实现对扫描对象的心电图监控。
