Description
技术领域
本发明涉及一种系统,所述系统带有用于在存储膜片(Speicherfolie)上记录X光照片的X光成像装置和用于所述存储膜片的读出装置。
背景技术
这样的系统现今使用在X光技术中、例如使用在牙医学中,以用于记录X光照片。存储膜片为了存储X光照片而具有磷光材料,该磷光材料嵌入在透明的基质中。由此产生存储中心部(Speicherzentren),所述存储中心部能够通过射入的X射线被带到已激发的亚稳态中。如果这样的存储膜片在X光设备中曝光例如以用于拍摄病人的咬翼片,则存储膜片包含已激发的和未激发的存储中心部的形式的潜隐的X光照片。
为了读出存储膜片,存储膜片在读出装置、例如扫描装置中利用读出光逐点地扫描,由此已激发的存储中心部的亚稳态被带到释放的状态中发出荧光。借助于检测单元探测荧光,从而利用相应的评估电子器件能够看见X光照片。
在医学中存储膜片的明确的跟踪和关联是极其重要的。为了该目的在此如在许多其它物流领域中那样使用识别系统。
发明内容
本发明的任务在于,给出用于为读出装置提供信息的系统和方法,其能够简单地操作、是可靠的且成本适宜的。
此外令人感兴趣的是,高效地且精确地制定所述存储膜片的读出过程。
该任务通过根据独立权利要求1所述的系统、通过根据另外的独立权利要求所述的存储膜片以及通过根据独立方法权利要求所述的方法解决。本发明的其它设计方案在从属权利要求中给出。
根据本发明的系统具有用于在存储膜片上记录X光照片的X光成像装置和用于所述存储膜片的读出装置。根据本发明设置成,所述存储膜片具有数据载体。此外设置成,所述X光成像装置或/和所述读出装置包括数据装置,所述数据装置带有写/读装置以用于将涉及X光成像的成像参数写入到所述数据载体上且用于读取存储在所述数据载体上的信息,其中所述写/读装置设置成,将读取的信息传递到所述读出装置处,从而在记录所述X光照片时使用的成像参数供所述读出装置使用以用于读出所述存储膜片。因此利用根据本发明的系统可行的是,为利用所述存储膜片的X光照片的记录,从所述数据载体上读出相应的信息。信息能够例如为成像参数,所述成像参数能够用于利用X光设备进行的成像。此外能够借助于待读出的信息探测存储膜片的使用次数,以为了能够计算或估算所述存储膜片的推测的磨损。例如,处于所述数据载体上的信息已经在读出过程之前供用于所述存储膜片的所述读出装置使用且所述存储膜片的读出能够例如已经与在记录所述X光照片时使用的所述成像参数相匹配。从下者得出特别的优点,即写入所述成像参数能够通过所述X光成像装置的数据装置执行。这使得写入到所述存储膜片上的写入过程的尽可能自动化成为可能,伴随着相应的优点如低的故障率和尽可能对可能敏感的数据进行保密。
在所述系统的一种实施方式中能够设置成,所述信息是明确地识别所述存储膜片的识别码。因此能够通过读出存储在所述数据载体上的信息,明确地识别所述存储膜片。这使得以其它方式获取的数据(如例如磨损数据的生成和/或获取)的关于存储膜片特定的链接成为可能。此外,与该识别相链接且以其它方式存储的关于所述存储膜片的数据还能够,例如被链接于明确的识别或被链接于存储在所述存储膜片上的所述X光照片。附加地存储在所述数据载体上的信息,如例如成像参数、磨损数据或类似物还能够与该明确的识别相链接。
在一种特别优选的实施方式中能够设置成,所述数据装置包括写/读装置以用于将涉及所述X光成像的成像参数写入到所述数据载体上。借助于所述写/读装置可行的是,利用所述存储膜片记录所述X光照片记录且将在此过程使用的所述成像参数存储到属于所述存储膜片的所述数据载体上。同时或备选地,在所述数据载体上存在的成像参数能够由所述写/读装置读出。因此单独地经由与所述存储膜片连接的数据载体能够实现独立于中央信息加工的信息传递。这一方面确保不中断地跟踪与在所述存储膜片上的所述X光照片的记录相关的成像参数。另一方面能够取消系统与数据库或类似物的持久的中央联结。
此外能够设置成,所述X光成像装置设置成,将所述成像参数传递到所述写/读装置处。因此在记录X光照片记录时使用的所述成像参数能够直接存储在所述数据载体上。
所述成像参数能够例如为电压、电流强度、曝光时间、剂量、剂量面积乘积、光圈值、针对病人的数据或/和针对任务的数据。所提及的成像参数的记录表示在所提及的参数和处于所述存储膜片上的X光照片之间的链接且因此允许跟踪所述X光成像,而不必保持集中式数据基础构架。
在一种特别优选的实施方式中设置成,所述数据载体为RFID应答器。相应地能够设置成,所述写/读装置为RFID写/读设备。基于RFID的连接技术能够例如根据标准ISO/IEC18000-x工作,但是不限制于该标准。
根据本发明的存储膜片针对这样的系统设计且具有光敏感的层、尤其用于存储X光照片且设计成,保存在遮光保护套中。设置成,所述存储膜片具有数据载体,该数据载体设计成,存储X光成像的成像参数且为了读出提供该成像参数。因此得到上文已经解释的优点。
根据本发明的用于为读出装置提供信息的方法具有如下步骤:借助于X光成像装置执行存储膜片的曝光过程,从而在所述存储膜片上产生X光照片。将在所述X光成像时使用的所述成像参数写入在与所述存储膜片永久关联的所述数据载体上。读出所述数据载体。在考虑所述数据载体的读出结果的情况下读出所述存储膜片。在曝光之前或之后,能够从所述数据载体读取所述存储膜片的表征所述存储膜片的标记。因此,在X光成像时使用的所述成像参数能够存储在所述数据载体上,且例如在读出所述存储膜片时或在解读处于所述存储膜片上的X光照片时读出和使用,而不必发生集中式数据流。在此写入所述数据载体的步骤包括存储表征所述曝光过程的信息。所述信息能够例如如已经提及的那样为在所述X光成像中的成像参数。所述存储膜片的读出考虑所述数据载体的读出结果。如果在读出所述存储膜片时例如考虑所述成像参数(所述X光照片在所述成像参数的情况下曝光到所述存储膜片上),则能够在某些情况下优化用于所述存储膜片的读出条件。在此重要的是,所述X光装置借助于所述数据装置将所述成像参数直接存储到所述存储膜片的数据载体中。因此不需要手动输入,且在存储在所述数据载体上的信息的准确性方面得到高度的可靠性。因此能够避免有意的或无意的错误输入。同时相比于例如必须执行手动输入的情况,整个工作进程在时间方面缩短且在可靠性方面改进。同时提供分散式存储的优点-所述数据的快速可用性、不需要耗力耗时地联结到集中式系统处、等等。
附图说明
现在参照附图进一步解释本发明。其中:
图1A、1B以示意图显示了根据本发明的系统的部件;
图2A-2D以示意图显示了根据本发明的存储膜片的不同的实施方式;
图3以示意图显示了读出装置的一种实施方式;以及
图4显示了根据本发明的方法的流程图。
具体实施方式
在图1A和1B中示出了用于提供信息的系统10。系统10包括:X光成像装置12(图1A),以用于以X光照片曝光存储膜片13,如其例如在牙医学中使用的那样;以及读出装置14,以用于读出在存储膜片13上存在的X光照片。为了记录X光照片,存储膜片13通常借助于未示出的保持装置在病人的口腔中布置在合适的部位处且经由X光成像装置12曝光。为了曝光,能够在X光成像装置12处调整对于分别的记录情形合适的成像参数。成像参数例如包括电压、电流强度、曝光时间、剂量、剂量面积乘积和/或光圈值,且如此确定记录条件。但是在成像参数的情况下还能够存在病人或任务特定的信息。
存储膜片13除了实际的对于X射线敏感的结构之外还包括RFID应答器16。RFID应答器16能够例如布置在通常设置的不透光的保护套处或其中。RFID应答器16与在X光成像装置12处的写/读装置18和在读出装置14处的读取设备20一起工作。
设置在X光成像装置12处的写/读装置18设计成,将一部分或所有成像参数写入到RFID应答器13上。为此,例如在曝光过程之前调整的理论值或/和在曝光过程期间或之后取得的测量值能够作为成像参数取得且写入到RFID应答器16上。附加地,写/读装置18还能够读出位于RFID应答器上的信息。例如能够在准备在存储膜片13上的X光成像照片时已经将例如涉及病人、任务、X光系统或/和整个系统的或类型的信息存储在RFID应答器16上,这些信息然后能够由X光成像装置12读出且如有可能结合在存储膜片13的曝光过程的配置中。
通过X光成像装置12借助于写/读装置18将信息写入到RFID应答器13上还能够包括写入实际上使用的成像参数或/和写入测量的测量值。写入能够独立于操作过程自动地在成像过程结束时进行。
在进行曝光之后必须读出位于存储膜片13上的X光照片。为此在系统10的显示的实施方式中设置读出装置14。读出装置14能够例如为扫描装置,该扫描装置借助于引导的激光束在存储膜片基质中激活亚稳态且如此使得读出X光照片成为可能。包含在RFID应答器16中的成像参数能够借助于设置在读出装置14处的读取设备20例如在存储膜片13的读出过程之前已经读出且如有可能为了读出/扫描过程使用。知道成像参数能够在某些情况下简化读出过程的调整。
在读出装置14中设置的读取设备20还能够实施为类似于写/读装置18的写/读装置。因此在读出存储膜片13之后还能够再次删除仍处于RFID应答器16上的信息。备选地或附加地,一部分或全部读出结果继而能够写到RFID应答器16上且因此存储。在RFID应答器16上还能够存放附注,该附注指出存储膜片13已经读出。
图2A-2D显示了存储膜片30的实施方式。存储膜片30如在图2A中显示的那样在其处理期间推入在保护套32中。保护套32用作机械保护,以用于保护敏感的存储膜片30免于刮擦或弯折。同时保护套32保护存储膜片30免于不期望的光射入,该光射入破坏处在于存储膜片30上的潜隐的存储照片或以不期望的方式曝光还未曝光的存储膜片。为了读出,在受保护的周围环境中从保护套中取出存储膜片30且利用读出光逐点地或逐行地扫描存储膜片,由此激发的存储中心部的存储X光照片的亚稳态释放且放出荧光。
图3显示了扫描装置100以用于读出这样的存储膜片30,该存储膜片以通过X光射线激发的亚稳存储中心的形式承载潜隐的X光照片。
扫描装置100具有用于存储膜片30的支撑装置114。例如存储膜片30能够利用负压如此固定在支撑装置114上,即使得通常为柔性的存储膜片30平坦地紧贴到支撑面114处。
扫描装置100此外包括作为读出光源的激光器116,该激光器产生带有处于红光中的波长的读出光束118,利用该读出光束存储膜片30的亚稳存储中心部能够激发而发出荧光。荧光120典型地处于蓝光中。
在扫描装置100的当前的实施方式中激光器116如此布置,即使得其将读出光束118对准可控制的偏转单元。可控制的偏转单元在此构造为镜子122。但是也能够设想除了镜子之外的其它偏转单元,如例如光学系统或类似者。镜子122能够实施为微镜、尤其实施为MEMS构件且因此使得在镜子122和支撑装置114之间没有相对运动或只有小的相对运动的情况下扫描存储膜片30的表面成为可能。备选地,镜子122还能够传统地设置为用于鼓形扫描器的转动的镜子。在该情况下,在支撑装置114和镜子122之间的相对运动借助于运输装置(未绘制)实现。
扫描装置100此外能够包括在图纸中以虚线表示的反射器124,该反射器不透光地包围围绕存储膜片30的整个测量空间,从而以存储膜片30为出发点的荧光120反射到光电检测器126(Photodetektor)。为了防止散射的读出光束118到达光电检测器126中,能够设置有合适的措施如例如二向色滤光材料。
为了控制读出过程,扫描装置100包括控制单元128,该控制单元例如除了控制功能之外还能够承担评估或修正功能。但是控制单元128本身或评估或/和修正功能还能够在单独的计算机上实现。控制单元128借助于线路130与支撑装置114、检测器126、激光器116以及镜子122连接。
为了读出,控制单元128操控激光器116以及镜子122且利用读出光束118逐点地连续地扫描存储膜片30。在此,放出的荧光120的强度借助于光电检测器126测量且在控制单元128中处理以输出。
在图2B-2D中示出了存储膜片30的三个不同的实施方式。在图2B中示出的存储膜片30在其上边缘处具有条形码结构34,该条形码结构在扫描线的方向35上基本上覆盖了存储膜片30的整个宽度。条形码结构34如此构造,即使得其在例如利用扫描装置100读出存储膜片时,在读出光束118的扫描方向上具有带有针对读出光束118的提高的反射率的区域36和带有较低的反射率、例如带有正常的反射率的区域38。带有提高的反射率的区域36能够例如用作散射区域。因此在扫描存储膜片时能够例如在正常读出过程之前检测由条形码结构34在逐行扫描时产生的散射光。由于在该过程中这不取决于高的空间分辨率,散射光能够例如利用简单的光电二极管(未绘制)探测。备选地或附加地,在要求低的灵敏性的情况下无论如何存在的光电检测器1126或许还能够承担该任务。
图2C和2D显示变型方案。不同于图2B的条形码结构,条形码结构40在扫描方向上35上仅仅覆盖存储膜片30的表面的一部分。在图2D中显示的变型方案中,条形码结构42垂直于逐行的扫描方向35延伸且因此需要在每个扫描线的开始端检测产生的散射光。
图4描述了用于为读出装置提供信息的方法的一种实施方式。该方法具有如下步骤:
借助于X光装置曝光存储膜片(S1)。在曝光过程中在存储膜片中潜隐地产生X光照片。
给与存储膜片永久关联的RFID应答器被写入曝光过程的成像参数(S2)。当在RFID应答器上仅仅应存放待调整的理论值时,写入(S2)的过程能够已经在曝光(S1)的步骤之前发生。备选地或附加地,能够在曝光过程(S1)期间或之后发生写入(S2)的过程,且备选地或附加地在曝光过程(S1)期间获取的测量值还能够存储在RFID应答器上。为了对RFID应答器进行写入,存储膜片还能够保留在X光装置中或已经从X光装置取出存储膜片。
读出在RFID应答器上存在的成像参数(S3)。存储膜片能够在曝光过程(S1)结束且对RFID应答器进行写入(S2)之后带到读出装置,以为了在该处读出成像参数。
处于存储膜片上的X光照片借助于合适的读出装置读出(S4)。读出装置能够例如为扫描装置,该扫描装置借助于激光器激活潜隐的X光照片且因此使得读出成为可能。读出成像参数(S3)和读出存储膜片(S4)的步骤能够彼此独立地进行。在读出存储膜片(S4)之前从RFID应答器读出成像参数(S3),以为了从成像参数推断出针对存储膜片的读出的合适的调整。
