具体实施方式
为了使本技术领域的人员更好地理解本发明中的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
参见图1，为本发明实施例提供的一种磁共振质量控制方法的流程示意图，如图1所示，本发明实施例示出了服务器进行磁共振质量控制的过程：
步骤S101：接收测试终端发送的质量控制报告集，其中，所述质量控制报告集包括至少一个质量控制报告，且所述质量控制报告集与所述测试终端具有对应关系；所述质量控制报告至少携带有待检测磁共振成像仪的检测标识，以及测试所述待检测磁共振成像仪得到的目标参数。
为了清楚地说明本发明实施例的技术方案，首先，对本发明实施例中的测试终端和服务器的架构方式进行详细说明。所述测试终端可以理解为计算机；而且，在具体实施时，该测试终端可以对一台待检测磁共振成像仪的成像结果进行测试，或者可以同时对多台待检测磁共振成像仪的成像结果进行测试，测试完成后得到每个待检测共振成像仪的质量控制报告。一台或多台测试终端与所述服务器通过互联网或者局域网通信连接，这样该服务器能够接收到测试终端发送的质量控制报告集，并将接收到的质量控制报告集存储在数据库中，该质量控制报告集中至少包括一个质量控制报告；每个质量控制报告集与测试终端一一对应，方便服务器将后续的处理结果发送至相应的测试终端，以供用户查阅使用。
为了得到质量控制报告，需要将专用磁共振质控体模严格按照测试说明放置在磁共振成像仪的成像中心，并严格按照测试说明设置好专用扫描序列和参数。
在一示例性实施例中，可以选用SE自选回波序列作为专用的扫描序列，所述参数可以包括线圈位置、TR值、TE值、层厚、层间隔、矩阵大小以及扫描起始位置等，以示例性实施例设置的专用扫描序列和参数，如表一所示：
表一：
Figure PCTCN2017089854-appb-000001
磁共振成像仪开始对专用磁共振质控体模进行扫描，以获得扫描数据。测试终端获取待检测磁共振成像仪的扫描数据，并对扫描数据自动进行处理、分析，得出质量控制报告并展示给用户。
所述质量控制报告中可以包括测试基本信息，如设备型号、生产厂家、生产日期、测试时间、专用磁共振质控体模种类、测试人员姓名等。质量控制报告中可以包括：本次扫描所用的扫描参数和序列。这些参数可以从扫描数据的头文件中读取。质量控制报告中可以包括目标参数，所述目标参数包括空间分辨率、对比度分辨率、信噪比、均匀度、激光校准、几何畸变以及伪影的一种或多种的组合。
为了便于根据所述质量控制报告进行数据分析，在本发明实施例中，所述质量控制报告中还携带有待检测磁共振成像仪的检测标识，所述检测标识可以包括上述测试基本信息中的磁共振质控体模型种类、设备型号和生产厂家，以及用于唯一标识该待检测磁共振成像仪的识别码中的一种或多种的组合。
这样，通过测试终端对待检测磁共振成像仪进行检测，客户无需再对扫描数据再进行手动分析，大大节约了客户的宝贵时间，使得客户从繁琐的数据处理中解放出来，可以更好的专注于设备的调整与维护。另外，质量控制报告由测试分析工作站按照统一的标准和处理方式得出，有利于质量控制报告的标准化。
步骤S102：根据所述检测标识，确定所述待检测磁共振成像仪的参考参数。
通过所述检测标识，确定所述待检测磁共振成像仪的参考参数，所述参考参数中同样包括空间分辨率、对比度分辨率、信噪比、均匀度、激光校准、几何畸变以及伪影的一种或多种的组合，这样根据所述参考参数，能够对待检测磁共振成像仪的成像质量进 行评估。
在第一种实施情况下，当所述检测标识包括所述待检测磁共振成像仪所使用的磁共振质控体模种类时，根据所述磁共振质控体种类，选择相应的参考参数，其中，所述参考参数包括AAPM标准参数和/或ACR标准参数。一示例性实施例中，如果所述检测标识中的磁共振质控体模种类为AAPM标准的质控体模，则选择AAPM标准参数作为所述参考参数；如果所述检测标识中的磁共振质控体模种类为ACR标准的质控体模，则选择ACR标准参数作为所述参考参数。当然，在具体实施时，还可以将AAPM标准参数与ACR标准参数的组合作为所述参考参数。
在第二种实施情况下，当所述检测标识包括待检测磁共振成像仪的设备型号时，从所述设备型号对应的质量检测报告中，获取所述参考参数。服务器能够从所述检测标识中获取待检测磁共振成像仪的设备型号，并根据所述设备型号检索数据库，从而得到相同厂家生产或者不同生产的、与待检测磁共振成像仪设备型号一致的磁共振成像仪的质量控制报告。在一示例性实施例中，可以从所有检索得到的质量控制报告中，提取与目标参数对应的参数，这样对应每个目标参数可以组成一个参数组，所有的参数组进一步组成参数集合，将该参数集合作为参考参数。
在第三种实施情况下，当所述检测标识包括待检测成像仪的识别码时，根据所述识别码获取待检测磁共振成像仪的历史质量检测报告；从所述历史质量检测报告中，获取参考参数。服务器可以根据识别码检索数据库，从而得到该待检测磁共振成像仪的历史质量检测报告，所述历史质量检测报告可以理解为该待检测磁共振成像仪多次检测并保存在数据库中的质量控制报告。从所有的历史检测报告中，获得目标参数对应的参数，对应每个目标参数可以组成一个参数组，所有的参数组组成为一个参数集合，将该参数集合作为参考参数。
在第四种实施情况下，当所述检测标识包括待检测磁共振成像仪的生产厂家时，从所述生产厂家所生产磁共振成像仪的质量检测报告，获取所述参考参数。服务器检索数据库中的生产厂家，从而获得该生产厂家生产的所有型号的磁共振成像仪所对应的质量控制报告。从所有检索得到的质量控制报告中，提取与目标参数对应的参数，这样对应每个目标参数可以组成一个参数组，所有的参数组进一步组成参数集合，将该参数集合作为参考参数。
步骤S103：通过对比所述参考参数与所述目标参数，得到所述待检测磁共振成像仪的设备质量报告。
通过步骤S102获得优化的参考参数，该参考参数能够为待检测磁共振成像仪的质量评估提供更全面的信息，进而对比所述参考参数与所述目标参数，得到所述待检测磁共 振成像仪的设备质量报告，使得设备质量报告能够全面准确地评估待检测磁共振成像仪的质量。
在第一种实施情况下，所述参考参数包括AAPM标准参数和/或ACR标准参数时，通过对所述参考参数与所述目标参数进行一一对比，从而可以判断该目标参数是否合格；如果所述目标参数不合格，则可以在设备质量报告中列出合格的目标参数、不合格的目标参数，以及不合格的目标参数与参考参数的差距等。而且，为了方便对待检测磁共振成像仪进行检修，在本发明实施例中，还可以根据不合格的目标参数，将不合格的目标参数对应的维护信息增加到所述设备质量报告中，例如几何畸变超出了所允许的范围，则在所述设备质量报告中给出“需要进行匀场处理”的维护建议。
在第二种实施情况下，所述参考参数包括同设备型号的参数集合时，一示例性实施例中，可以将目标参数与参考参数按照大小顺序排序，从而确定所述目标参数处于参数集合中的位置，进而根据目标参数的位置确定待检测磁共振成像仪的质量等级；具体地，当参数值越大代表性能越好时，可以将目标参数与参考参数按照从大到小的顺序排序，如果所述目标参数位于靠前的位置，则表示该待检测磁共振成像仪的目标参数在同类型的磁共振成像仪中处于优良范围，确定所述待检测磁共振成相应质量等级为优良；或者，如果所述目标参数位于靠后的位置，则表示该待检测磁共振成像仪的目标参数在同类型的磁共振成像仪中处于较差范围，确定所述待检测磁共振成像仪的质量等级为较差。当然，需要说明的是，上述确定待检测磁共振成像仪的质量等级的方式仅是一示例性实施例，在具体实施时，可以首先对参考参数进行优化，例如根据参考参数确定多个参数范围，每个参数范围对应相应的质量等级，根据目标参数所属于的参数范围，确定待检测磁共振成像仪的质量等级。另外，所述质量等级在具体实施时，可以根据测试需求划分为任意多个利于优、良、中、差等，在本发明实施例中不做限定。将每个目标参数对应的质量等级增加到设备质量报告中，供用户评估使用。
在第三种实施情况下，当参考参数包括历史质量检测报告中提取到的参数集合时，通过对比所述参考参数与所述目标参数，得到所述待检测磁共振成像仪的预警等级。在一示例性实施例中，可以从参数集合中对于每个参数组，提取得到每个参数组对应的最大参数、最小参数以及平均值，以对应参数越大对应性能越好为例，详细说明预警等级的确定过程；当目标参数大于对应的最大参数时，则表示该待检测磁共振成像仪的目标参数性能优秀，设定最低预警等级；当目标参数处于最大参数和平均值之间时，则表示该待检测磁共振成像仪的目标参数性能较好，设定较低的预警等级；当目标参数处于平局值和最小参数之间是，则表示待检测磁共振成像仪的目标参数性能低于平均值，设定较高的预警等级，以提醒用户需要针对相应的目标参数进行检修；当目标参数小于最小参数时，则表示待检测磁共振成像仪的目标参数在历史数据中最差，设定最高的预警等 级，以警示用户需要立即针对相应的目标参数进行检修。在另外一个示例性实施例中，可以根据该成像仪的历史质量控制报告生成该成像仪的各个性能参数随时间变化的趋势图，并反馈给客户，以使客户对所使用的成像仪有更好的了解，从而对成像仪进行针对性的维护，在本发明实施例中不再赘述；而且，根据所述趋势图，可以进一步确定该待检测磁共振成像仪的预警等级，例如如果趋势向性能坏的方向，则设置较高预警等级，如果趋势向性能好的方向，可以设置低预警等级等。另外，需要说明的是，上述预警等级可以包括任意多个等级，在本发明实施例中不做限定。将每个目标参数的预警等级加入设备质量报告中，从而方便用户根据该待检测磁共振成像仪的历史记录，分析确定性能变化趋势，进而制定维护策略。
在第四种实施情况下，当参考参数包括同生产厂家的磁共振成像仪的参数集合时，通过对比所述参考参数与所述目标参数，确定所述待检测磁共振成像仪的质量排名。一示例性实施例中，通过对目标参数和参考参数进行按照性能从优到差的顺序进行排序，可以确定待检测磁共振成像仪在该生产厂家所有型号的磁共振成像仪的质量排名。在另一示例性实施例中，统计出同一厂家磁共振成像仪的某个参数的测试合格率，并反馈给客户；进而根据所述测试合格率，按照测试合格率从高到低的顺序排序，得到待检测磁共振成像仪的质量排名。将每个目标参数的质量排名加入设备质量报告中，从而方便用户评估该待检测磁共振成像仪在生产厂家的所有磁共振成像仪中的质量排名。
步骤S104：根据所述对应关系，将所述设备质量报告发送至相应的测试终端，以使所述测试终端显示设备质量报告。
服务器将生成的设备质量报告发送至相应的测试终端，以将设备质量报告在测试终端上显示，用户可以在测试终端上查阅所述设备质量报告，进而评估待检测磁共振成像仪的成像质量，以及确定维护策略。而且，为了保证设备质量报告准确发送到相应的测试终端，在具体实施时，测试终端可以在每个生成的质量控制报告中打上自己的识别戳，建立质量控制报告与测试终端的对应关系，服务器进而根据所述识别戳，确定将产生的设备质量报告发送至测试终端显示。
而且，为了方便用户查看所述设备质量报告，所述服务器还能够将设备质量报告发送至用户终端，所述用户终端可以理解为用户的手机、PAD或者笔记本等移动终端；服务器可以通过注册的方式建立用户终端与待检测磁共振成像仪的对应的关系，从而在用户通过用户终端发送请求时，将相应的设备质量报告发送到用户终端上显示。
另外，为了方便磁共振成像仪的生产厂家获取相应的质量控制报告，所述服务器还与生产厂商终端相连接，服务器在接收到生产厂商的请求时，将与所述生产厂商对应的质量控制报告发送至生产厂商终端。
