技术领域
本公开大体上涉及数字成像***,并且特别地涉及模块化成像***的管理。
背景技术
许多各种设计的放射成像***是已知的并且目前在使用中。这样的***基于引导朝向感兴趣受检者的X射线的产生。X射线穿越该受检者并且撞击膜或数字检测器。在医疗诊断背景中,例如这样的***可用于使内部组织可视化并且诊断患者疾病。在其他背景中,部件、行李、包裹和其他受检者可成像以评定它们的容纳物并且用于其他目的。一般来说,由本公开提及的类型的X射线***可包括投影X射线***、荧光***、X射线层析***、计算机断层扫描***和各种混合或组合形态***,其结合其他成像物理、例如超声、正电子发射断层扫描、磁共振成像等等利用X射线成像。
X射线成像***可以是便携或静止的,并且一般可包括成像器和检测部件。该成像器部件可包括例如会在X射线成像室中在c形臂扫描架或定位臂上发现的大致上静止的X射线源,或移动X射线源,例如可邻近患者病床或相似区域部署的轮子上的移动X射线源等。检测部件可包括有线或无线检测器,其可与该静止或移动源部件中的任一个兼容。然而,这样的检测器当便携时可仅在一个特定X射线成像***内使用。即,单个检测器典型地不能在不同的成像***中使用,因为它可永久地集成进入特定成像***。因此,如果单个检测器子***可以与多个成像子***一起使用,医院可能够更优地利用它的资源。在这样的***中,存在例如放射学家或技术人员等用户可不经意地尝试利用与特定成像器子***几乎没有任何可操作性的检测器并且使患者经受不必要的辐射的可能性。在另一方面,即使用户具有兼容的检测器和成像子***,用户必须在使患者经受适当水平辐射之前确保它们互相关联。

在另外的实施例中,提供X射线成像***。该***包括能够与一个或多个自主检测器子***一起操作的自主成像子***,能够与该自主成像子***一起操作的多个自主检测器子***,并且其中该自主成像子***和该自主检测器子***中的至少一个配置成形成该自主X射线成像子***和该自主检测器子***中的一个之间的操作关联,该关联允许成像数据的无线交换,并且产生该关联的用户可察觉指示。

具体实施方式
本发明的一个或多个特定实施例将在下文描述。为了提供这些实施例的简洁说明,可不在该说明书中描述实际实现的所有特征。应该意识到在任何这样的实际实现的开发中,如在任何工程或设计项目中,必须做出许多实现特定的决定以达到开发者的特定目标,例如遵守***相关和业务相关的约束等,这样的约束可在实现之间变化。此外,应该意识到这样的开发努力可是复杂并且耗时的,但对于得到该公开的利益的那些普通技术人员仍将是设计、建造和制造的例行任务。
当介绍本发明的各种实施例的元件时,冠词“一”、“该”和“所述”意在表示存在元件中的一个或多个。术语“包括”、“包含”和“具有”意为包括的并且表示除了列出的元件可存在另外的元件。此外,尽管术语“示范性的”可在本文中连同目前公开的技术的方面或实施例的某些示例使用,将意识到这些示例在性质上是说明性的并且术语“示范性的”不在本文中使用以用于指示关于公开的方面或实施例的任何优选或要求。此外,术语“顶部”、“底部”、“上面”、“下面”、其他位置术语和这些术语的变化形式的任何使用为了方便做出,而不要求描述的部件的任何特别取向。
本实施例提供了在X射线成像应用中使用的自主子***,例如自主检测器和成像器。本实施例涉及随同该申请同日提交的名为“WIRELESS X-RAY DETECTOR OPERATION COORDINATIONSYSTEM AND METHOD(无线X射线检测器操作协调***和方法)”的美国专利申请号12/776,207、2009年7月20日提交的名为“APPLICATION SERVER FOR USE WITH A MODULAR IMAGINGSYSTEM(用于与模块化成像***一起使用的应用服务器)”的美国专利申请号12/506067和2007年11月2日提交的名为“MEDICALIMAGING SYSTEM(医疗成像***)”的美国专利申请公开号US20090118606,其中全部通过引用全文结合于本公开中。
自主检测器引入成像环境,这些检测器可以与多个成像子***(例如,X射线源、控制器、存储介质)一起使用。自主检测器可具有与多种成像子***动态关联的能力。然而,在任何一个时间点,该关联可是唯一的,因为一个成像子***和一个检测器典型地适合进行医疗成像检查。然而,即使在自主检测器和成像子***可以动态关联的情况下,可存在操作员或技术人员可能尝试使用未与使用中的成像子***关联的错误检测器的风险。即,检测器可能没有在物理或功能上配置成从成像子***接收辐射,或可能没有用适当的软件和/固件配置以允许在成像照射(imaging exposure)期间由检测器产生的成像数据的传输。
因此,现在认识到便于检测器与成像子***的关联的方法和***是可取的。另外,这样的方法和***也可以是可取的以便于对当前与将在给定检查过程中使用的成像子***关联的检测器的识别,并且还便于对当前与将在给定检查过程中使用的检测器关联的成像子***的识别。该方法和***还可允许用户确认或纠正其之间所建立的关联。
本实施例针对提供用于关联的方法和具有能够进行关联序列的相应部件的***。该序列可包括用户和***(例如,与一个或多个自主子***通信耦合的成像***)两者可进行的动作。该动作可包括形成检测器和成像器子***之间的唯一关联和向用户指示该唯一关联。用户(或控制器)可在适当的情况下使用例如操作连接到对其期望关联的成像部件的工作站确认和/或纠正该关联。
现在转向附图,图1图解图示用于采集和处理图像数据的成像***10。在图示的实施例中,该成像***10是包含自主部件的数字X射线***。在图1中图示的实施例中,成像***10包括邻近准直器14安置的X射线辐射源12。该准直器14允许辐射流16传递进入例如患者18等对象或受检者安置在其中的区域。一部分辐射20传递通过受检者或其周围并且撞击便携数字X射线检测器22。该检测器22可将在它的表面上接收到的X射线光子转换为电信号,其被采集并且处理以重建受检者内的特征的图像。
辐射源12由电源/控制电路24控制,电源/控制电路24向检查序列供应电力和控制信号。检测器22通信耦合于检测器控制器26,其命令在检测器22中产生的信号的采集。在图示的实施例中,检测器22可凭借任何适合的有线或无线通信标准与该检测器控制器26通信。在某些实施例中,该检测器控制器26的功能中的一些或所有可集成在也容置检测器22的结构内,即该检测器控制器26和检测器22可提供为单一装置。除其他功能外,该检测器控制器26可执行各种信号处理和过滤功能,例如用于动态范围的初调、数字图像数据的交叉存取(interleaving),等等。
在描绘的实施例中,电源/制电路24和检测器控制器26可与***控制器28通信,并且响应于来自***控制器28的信号。一般,该***控制器28命令成像***的操作以执行检查规程并且处理采集的图像数据。在目前的上下文中,***控制器28还包括信号处理电路(典型地基于程序化通用或专用数字计算机)和关联的制造品(例如光学存储装置、磁性存储装置或固态存储装置),其用于存储由该计算机的处理器执行以实现各种功能的程序和例程以及用于存储配置参数和图像数据等等。
根据本文描述的方式,成像***10的不同部件可提供作为自主和可分开的子***。例如,源12、准直器14和/或电源/控制电路24中的一些或所有可提供作为成像器子***30。同样地,检测器22可提供作为自主和可分开的检测器子***32。在图示的实施例中,自主检测器子***32包括检测器控制器26,其如上文指出的那样可与检测器22一体式提供。在其他实施例中,检测器控制器26可与检测器22分开提供(例如在下游工作站或服务器上或作为下文论述的***控制器28的部分)或可分布成使得检测器控制器26的方面提供在检测器22上而其他方面提供在下游。采用该方式,自主成像器子***30或自主检测器子***32中的任一个可在动态成像环境中被交换以用于具有相同或不同能力的不同源或检测器子***。
在描绘的实施例中,成像器子***30包括***控制器28。然而,在其他实施例中,***控制器28可是独立部件或子***或可是检测器子***32的部分。在其他实施例中,***控制器28的功能、硬件和/或软件可分布成使得***控制器28的不同硬件、软件和/或固件方面适当地分布在成像器子***30、检测器子***32和/或分开且不同的控制子***之间。采用该方式,成像***10的源、检测和/或控制功能可完全或部分由可以看作模块化部件的自主子***提供,即一个检测器子***32或成像器子***30可互相交换以提供不同的相应检测或X射线源功能。
如本文使用的,术语“自主的”描述了即使当它没有与成像***10的补充子***连接或关联时具有通信能力的***或子***。例如,短语“自主检测器子***”描述了即使当它没有与成像***10连接或关联时具有与例如服务器等网络的通信能力的检测***。此外,在一个实施例中,即使当自主检测器子***32与自主成像器子***30关联时,自主检测器子***32可提供通信能力(例如与第二自主成像器子***30或第二网络通信的能力)。
不同情况来说,自主***部件在它的***设计、***实现、应用部署和/或服务方面可以是独立可操作的。这样的自主部件可配置用于并且能够与多个其他补充或配对自主部件一起使用。因此,在一个实施例中,主要部件(例如,自主成像器子***30和自主检测器子***32)中的每个可考虑作为网络节点,其在网络环境中作为自主实体操作。在这样的环境中,不同类型的自主成像器和/或检测器子***(例如来自相同或不同厂家,具有相同或不同能力和/或大小等等)可以在形成成像***10的各种组合中使用。
在图示的实施例中,成像器子***30和检测器子***32无线地通信,其可允许例如检测器22在适当的情况下与另一个无线检测器互换。如此,自主检测器子***32和成像器子***30的一个或多个部件可包含指示其之间的关联的特征。如本文使用的,术语“关联”可考虑为指示两个或更多部件互相链接以允许成像。该关联可是有线或无限的,并且可允许如上文描述的每个部件之间的通信,例如以协调X射线源、检测器和控制器之间的成像例程,如下文参照图5描述的那样。可通过在附近放置两个或更多子***、用另一个子***扫描一个子***、用分开的装置扫描两个或更多子***(例如,每个的条形码)等等来进行该关联,如在下文进一步详细描述的那样。实际上,通过在检测器子***32和成像子***30之间进行关联,检测器子***32的检测器22可自动配置以用于与成像子***30一起使用,如在名为“PORTABLE DIGITAL DETECTOR SYSTEM(便携数字检测器***)”的美国专利号7,298,825中描述的那样,其通过引用全文结合于本公开中。
关联指示可向用户提供辨别哪些自主部件互相关联或链接的能力。该指示可是听觉的、视觉的、触觉的,或这些的任意组合,并且可以或可以不在每个关联的子***/装置上同时存在。在图示的实施例中,视觉指示器34提供在检测器22上,其可以是闪烁或纯色灯,代码或其他数字或标识符的读出器,或固定到或建入检测器22的外壳的相似特征。同样地,成像器子***30可具有视觉指示器36。在图示的实施例中,该视觉指示器36设置在***控制器28上。然而,应该注意到该视觉指示器36可提供在成像器子***30的任何部分上,例如在包含成像器子***的相应部件中的所有的外壳上。一般,视觉指示器34和36提供在每个相应部件上的区域中以允许对于用户容易可见,视觉指示器34和36是大致上相同的并且采用大致上并行的方式工作(即,具有相同的颜色/色调和其的变化,相似地闪烁等等)。此外,应该注意到指示器34和36可大致上同时受子***30和/或32中的变化影响。实际上,本实施例设想在两个或更多子***(例如两个、三个、四个、五个或更多包括控制器、成像器、检测器等等的子***等)之间的这样的关联。
成像器子***30和/或检测器子***32可响应于由操作员经由操作员工作站38提供的命令和扫描参数进行各种功能,例如扫描操作和数据采集等。从工作站38,操作员能够发起提供给***控制器28的各种成像例程。工作站38可提供用于确认关联或用于完成例如在工作站38连接到的显示器40上提供的关联序列(例如通过输入由成像器子***30和/或检测器子***32提供的唯一代码等)的提示。实际上,工作站38可提供中央位置给用户以协调各种子***之间的关联。
显示器40还允许操作员查看相关的***数据、成像参数、原始成像数据、重建数据等等。另外,***10可包括耦合于操作员工作站38的打印机42。此外,操作员工作站38可包括或耦合于图片存档和通信***(PACS)44。PACS44可耦合于远程***46、放射科信息***(RIS)、医院信息***(HIS)或内部或外部网络,使得在不同位置的其他人可以获得对图像数据的访问。
透视图在图2中提供作为成像***10的示例。除上文关于图1描述的特征外,成像***10包括用于定位辐射源12的采用架空管支撑臂50的形式的定位部件。在其他实施例中,辐射源12可提供在C形臂或其他旋转结构上以允许从各种角位置成像。此外,在描绘的实施例中,自主成像器子***30可包括源12,并且可以或可以不包括定位子***(例如臂50或C形臂)、电源/控制电路和/或***控制电路(例如可提供作为源12的部分或作为与源12通信的工作站38或服务器的部分)。
如上文指出的,在某些实施例中,源12和/或成像器子***30可经由有线连接(例如以太网电缆等)或经由无线连接(例如经由无线收发器等)接收指令(例如从工作站38)。注意随或在每个子***(例如,成像子***30和检测器子***32)内包括的这样的无线收发器可利用任何适合的无线通信协议,例如超宽带(UWB)通信标准、蓝牙通信标准或任何802.11通信标准。
数字检测器22还可包括一个或多个处理器部件和/或存储装置,其能够存储采集的图像数据和/或将由该一个或多个处理部件执行的程序、例程或规程,例如关联规程等。例如,在各种实施例中,该存储装置可包括光学存储装置、磁性存储装置或固态存储装置,其包含能够进行关联过程的算法并且包含关于检测器的信息,例如可传送到其他子***的它与各种成像设备的兼容性、能力、设计等等。
在图示的实施例中,成像子***30和检测器22之间的关联经由在检测器22上的视觉指示34和成像子***30上的视觉指示36来指示。视觉指示34和36可例如在关联之前是一个颜色(例如,红色),在关联期间是另一个颜色(例如,黄色),并且当关联时是另一个颜色(例如,绿色)。在另一个实施例中,用户可在关联序列完成之前确认子***之间的临时关联(例如通过处理在工作站38的提示)。作为示例,用户可发起关联序列使得成像子***30或***控制器28例如凭借辨别电路在它的检测范围内无线地检测任何便携检测器22。工作站38可然后显示由成像子***30辨别的检测器22。另外,用户可进行关联动作,例如扫描在子***30和32中任一个或两者上的条形码或将一个或多个检测器22递送至临近成像子***30(例如,用于RFID辨别)以识别期望用于进行成像例程的检测器22和成像子***30。关联指示34和36然后可闪烁,是某个颜色,或任何相似指示,指示特定检测器22和成像子***30临时关联并且等待由用户确认。当例如在工作站38由用户确认时,视觉指示34和36然后可闪烁另一个颜色,具有稳定的光(即,不闪烁),是不同的颜色等等。指示的选择可取决于许多因素,其包括部署成像***10的环境、来自子***的部件的其他视觉或听觉指示或发射等等。
在存在对于用成像子***30辨别和与成像子***30的关联可用的多个检测器的情况下,关联指示以及由用户确认可是可取的。实际上,在其中多个无线检测器22在成像子***30的无线能力的操作范围内的实施例中,当没有进行确认时用户可难以马上关联特定的便携检测器22。例如,***10还包括存放站52,其提供用于存放并且在一些实施例中对变化形状和大小的多个无线X射线检测器54充电。可壁装式底座56在它的面上包括多个无线X射线检测器存放点58。因此,存放站52适应于收容和存放多种不同的检测器54。
存放在存放站52内的检测器54中的一些或所有可具有无线关联能力。因此,在存放站52在成像子***30的无线范围内的情况下,存放的检测器54中的一些或所有可由具有与其关联的能力的成像子***30辨别。相应关联指示器60可提供给存放的检测器54中的每个,使得用户可容易识别不经意的关联,或是否用户期望使用存储的检测器54用于图像采集。在用户凭借关联指示器60识别无心关联已经发生的情况下,用户可例如凭借工作站38或使用关联按钮62直接在便携检测器22上重新发起关联。关联按钮62可发起、重新发起和/或确认与成像子***30的关联。例如,在一个实施例中,用户可观察在一个子***、例如成像子***10等上的指示,并且经由关联按钮62确认检测器22上的指示。
在相似的实施例中,检测器22和/或成像子***30可具有用于进行关联的用户界面。例如,在一个实施例中,例如在利用数字或代码识别每个子***(例如,识别信号)的实施例中等,相应用户界面可允许用户输入或认可另一个子***的识别码或数字以确认关联。在成像子***的识别码或数字在检测器上查看的情况下,用户可通过按下关联按钮62认可代码是正确的或不正确的(即,确认)。在其他实施例中,例如当成像子***30显示检测器22的识别码或数字时,用户可通过按下相似的关联按钮(或其他用户界面)确认。
在一些实施例中,手持装置64可提供用于协调关联过程。可以是个人数字助理(PDA)或相似装置的手持装置64可担当扫描装置,例如用于扫描在成像子***30和/或检测器子***32上的相应条形码以形成唯一关联。例如,用户可扫描成像子***30和检测器子***30上的条形码,并且装置64可将识别用的条形码传送到用于关联的补充子***(即,检测器条形码提供给成像子***并且反之亦然)。手持装置64还可具有无线通信电路使得信息可以提供给工作站38和子***30和/或32中的任一个并且从其提供。装置64可通过存储在工作站38上的各种应用程序(其包括例如关联指示和确认等的关联规程)实现远程导航。因此,装置64可具有屏幕66,其允许通过工作站38的应用程序的导航并且还使装置64能够担当便携子***协调装置。该装置还包括键68,其允许用户输入例如由自主子***唯一指示的代码的值、各种命令以形成用户限定名称等等。实际上,手持装置64可包括例如扫描仪等其他特征以扫描并且关联每个子***。当具有关联能力的多个无线检测器存在时,装置64还可便于与例如一个或多个特定检测器22等特定子***的关联。此外,用户可查看关于检测器22的各种信息,例如电池充电水平、当前关联、能力、兼容性等等。还可显示关于成像子***30的信息,例如控制方案、例如X射线功率等源信息、成像规程等。
一个或多个关联的检测器22可与患者台70和架子72中的一个或两个一起使用以便于在成像规程期间的图像采集。特别地,台70和架子72可配置成收容一个或多个数字检测器22。例如,数字检测器22可放置在台子70的上表面上,并且患者18(更具体地,患者18的感兴趣解剖)可安置于检测器22和辐射源12之间的台子70上。在一些其他实例中,一个或多个检测器22可安置在台子70的上表面和患者18下面的狭缝74中,或辐射源12和检测器22可关于患者18水平安置用于跨台成像。此外,架子72可包括适应于收容数字检测器22的收容结构76,并且患者18可邻近架子72安置以使图像数据能够经由数字检测器22采集。
在一个实施例中,成像***10可以是设置在固定X射线成像室中的静止***,例如一般在图2中描绘的并且上文参照图2描述的静止***。然而,将意识到目前公开的实施例还可与包括移动X射线单元和***的其他成像***一起采用。例如,在其他实施例中,移动X射线单元可移动到患者恢复室、急诊室、手术室或类似的以实现患者成像而不要求将患者运送到专用(即,固定的)X射线成像室。
移动X射线单元的一个这样的实施例在图3中图示。在图示的实施例中,移动无线X射线***90包括第一移动X射线基站92,其可辨别位于该第一移动X射线基站92的操作范围内的多个数字X射线检测器94、96、98和100。即,该第一移动X射线站92可考虑为包含成像子***30。该第一移动X射线基站92可包括有轮底座102,其允许用户将该移动X射线单元移动到各处,例如从一个房间到另一个或一个病床到另一个。该第一移动X射线基站92具有X射线源104,其与数字X射线检测器94-100中的一个或多个结合使用。在一些实施例中,该第一移动X射线基站92可与多个X射线检测器94、96、98和100通信,如之前在2007年11月2日提交的美国专利申请号11/934,338中描述的那样,其通过引用结合于此。
第一移动X射线站92容置***电子电路106,除上文描述的过程之外其还辨别(检测)检测器94、96、98和100以供关联。另外,该***电子电路106提供并且控制到X射线源104、有轮底座102和设置在第一移动X射线基站92的表面上的关联指示器108(例如凭借照明电路等)的电力。在图示的实施例中,该关联指示器108提供视觉指示。
第一移动X射线基站92还具有耦合于显示器112的操作员工作站110。例如,辨别的检测器94、96、98和100在显示器112上显示。当发起关联序列(在已经辨认各种检测器后由用户或由***90自动地)时用户可进行如上文描述的辨认程序以将检测器94、96、98和100中的一个或多个与第一移动X射线站92关联。
显示器112可具有检测器“A”94、检测器“B”96、检测器“C”98和检测器“D”100的读出,其中已经与第一移动X射线基站92关联的那些如此指示(例如,加亮)。此外,检测器94、96、98和100中的每个可具有相应的关联指示器114、116、118和120。应该注意到该关联指示器114、116、118和120可进行与第一移动X射线基站92的关联指示器108的那个几乎相同的任务。在图示的实施例中,检测器“A”114描绘为提供与第一移动X射线站92的关联的视觉指示。
采用与第一移动X射线站92相似的方式,第二移动X射线站122可辨认无线检测器114、116、118和120。该第二移动X射线站122可包括与上文关于第一移动X射线站92描述的那些相似或相同特征。如此,移动X射线站可看起来相似或相同,并且在没有某种关联指示的情况下,其可能难以区别。因此,对于用户可能难以确定哪些检测器已经与每个移动X射线站关联。因此,通过在每个检测器和X射线站上提供关联指示,例如在检测器“C”98上的视觉指示118和在第二移动X射线站122上的关联指示124,快速确定和/或重新配置其之间的关联可是可能的。例如,根据在图3中示出的指示,用户可容易确定检测器“A”与第一移动X射线站92关联,并且检测器“C”98与第二移动X射线检测器关联。
上文描述的无线移动X射线单元以及无线检测器的电路在图4中图解图示,并且采用与在图1中描述的大体上相同的方式操作。除上文描述的任务外,电源130提供电力给有轮底座106的移动驱动单元132(在移动单元的实施例中)。如上文,***控制器134命令成像***的操作以执行检查规程并且处理采集的图像数据并且可包括或可响应于处理器136。该处理器136还从检测器94接收图像数据并且处理该数据以重建对象图像。
处理器136还链接到检测器辨别电路138,其用于检测检测器在第一移动X射线基站92的操作范围内的存在。如果没有检测器在第一移动X射线站92的操作范围内被关联或辨别,处理器136可发送信号给***控制器134以禁止或阻止X射线从X射线源104发射。检测器辨别电路138还链接到***控制器134。检测器辨别电路138链接到无线通信接口140,其允许与第一移动X射线站92的操作范围内的检测器无线通信和对其的辨别。在第一移动X射线站92(即,成像器子***)与检测器临时或另外关联的实施例中,处理器136可发送信号给照明电路142以激活关联指示器,例如关联指示器108(图3)等。另外或备选地,第一移动X射线站92还可与服务器通信。处理器136还链接到***设备144,其可包括显示器、用户界面、存储器等等。
检测器94包括用于与第一移动X射线站92无线通信的无线通信接口146。检测器94还可与服务器通信。注意到该无线通信接口146可利用任何适合的无线通信协议,例如上文关于图1提到的那些。此外,检测器94耦合于检测器控制器148,其协调对各种检测器功能的控制。***控制器134以及检测电路检测器辨别电路138可无线提供控制信号给检测器控制器148。提供控制信号给各种检测器部件的处理器150、检测器控制器148以及描绘的电路中的所有从电源152接收电力。该电源152可包括电池。
代表图像的电信号由检测器接口电路156转换成数字值,检测器接口电路156将该值提供给处理器150用于图像建立。备选地,成像数据可从检测器94发送给服务器以处理成像数据。处理器150还链接到照明电路158。检测器控制器148响应于从第一移动X射线站92接收的信号可发送信号给处理器150以发信号给照明电路158点亮灯以指示检测器94与第一移动X射线站92的关联。与处理器150通信的存储器160可存储各种配置参数、校准文件和检测器识别数据。另外,该存储器160可存储检测器94配置成与其一起操作的所有X射线***10的列表,以及限定检测器94与X射线***10的特定版本和/或软件版本的兼容性的表格。
成像部件的这样的移动性可允许自主成像器子***30、检测器子***32和/或工作站38中的一个或多个在例如上文指出的HIS、RIS和/或PACS等网络上提供为节点。此外,每个部件可是移动的、无线的等,使得每个子***和/或工作站可配置成与许多其他子***通信,如在图5中图示的。采用该方式,检测器子***32可经由无线网络连接将采集的图像数据传送给成像器子***30和工作站38中的任一个或两个。同样地,工作站38可经由无线网络连接与成像器子***30或检测器子***32中的一个或两个通信和/或对其控制。相似地,成像器子***30可经由无线网络连接与工作站38或检测器子***32通信。在这样的联网实施例中,自主部件(例如,成像器子***30、检测器子***32和工作站38)可独立操作并且从而可在它们自身中通信或与网络上互相独立的其他装置通信。根据本文描述的方式,成像***30包括关联指示器36以向用户提供一个或多个检测器与其无线关联的标记。相似地,检测器子***32具有关联指示器34,其提供检测器22与成像子***30关联的标记。如上文指出的,工作站38可经由显示器提供关于本地网络(例如,关联的子***)的信息。
本实施例设想关联指示器和可选地关联按钮(例如,用以发起、确认或重新发起关联)安置在无线检测器22的各种位置上。图6图示检测器22A-22E的若干示例,其具有关联指示器和在一些实现中的关联按钮170的变化安置。应该注意到关联指示器34和/或关联按钮170可提供作为检测器的内建特征,或备选地可提供作为可改装的附加装置。因此,关联指示器34和关联按钮170可与多种检测器兼容。此外,例如那些缺少无线能力的一些检测器可改装成具有无线通信接口,例如上文提到的那些等。检测器22A是检测器22仅具有关联指示器34的实施例。关联指示器34可安置在检测器22A的手柄部分172上或在检测器22A的本体174上,例如在检测器22A的本体174的四个角中的任何角处。检测器22B是检测器22具有与关联按钮170结合的关联指示器34的实施例。即,关联按钮可以是提供指示和发起功能的点亮按钮。在检测器22B中,结合的按钮在手柄172上。检测器2C是检测器22具有在手柄172上的关联按钮170和安置在检测器本体174上或内的关联指示器34的实施例。检测器22D是检测器22具有作为分立特征都设置在手柄172上或内的关联指示器34和关联按钮170两者的实施例。检测器22E是检测器22具有设置在手柄172上或内的关联指示器34而关联按钮170安置在本体174上或内的实施例。检测器22F是检测器22具有关联指示器34和关联按钮170作为结合特征而设置在检测器22F的本体174上或内的实施例。应该注意到尽管上文的说明提供其中关联指示器34和/或关联按钮可安置在检测器22上的示例,许多其他配置可是可能的并且认为是在本公开的范围内。
X射线***10关联无线子***的能力可或可以不限于正与成像子***30关联的一个检测器22。例如,在例如创伤情况等某些环境下关联两个或更多检测器22可是可取的。在这样的情况下,医疗人员可宁愿尽可能少地移动受伤的人。结合由多个检测器22提供的图像数据以形成增加的照射面积的能力可减少移动受伤的人的需要。图7图示在这样的情况下多个检测器22的使用。为了进行这样的成像,患者18安置在X射线源26下面的台子70上。两个关联的检测器180和182安置在患者18下面。与单个检测器22的使用相比,采用这样的设置的如上文描述的成像子***30的使用允许用户对患者18的更大面积(例如,几乎两倍大)成像。
如上文指出和描述的,本实施例针对提供用于关联的方法和具有能够进行关联序列的相应部件的***。该序列可包括用户和***(例如,控制器)两者可进行的动作。这样动作在下文关于图8(其是描绘由用户进行的动作的过程流程图)和图9(其是描绘由***10进行的动作的过程流程图)描述。
当对患者18成像时用户(技术人员)可进行一组序列,以提供成像设备开始并且完成对患者18的照射以产生图像。用户的示例工作流程在图8中图示。该成像工作流程190以用户提供自主检测器和成像子***(框192)开始。用户可通过调动移动成像单元到室或靠近病床或通过引导患者18到例如在图2中描述的等成像区提供子***。用户可选择特定检测器或多个检测器以在成像例程中使用,并且可发起关联序列(框194)。关联序列发起可包括在工作站发起、在任一子***发起(例如经由关联按钮等)。用户可进行动作,例如扫描在成像和/或检测器子***中的任一或两者上的条形码或使检测器22的短程无线收发器经过成像子***30的短程无线收发器以指示期望关联哪些部件。一旦临时关联已经由***进行,用户可确认特定成像序列的关联和照射参数(框196)。关联确认可在工作站处、在子***中的任一或两个上、或在分开的手持装置上进行,如上文提到的。作为示例,弹出窗口或相似指示可提供在工作站38的显示器40处,列出关联的检测器22和成像器子***30的名称或序列号。用户可通过接受该警告而确认,或可通过重新发起关联直到指示期望的部件来纠正关联。当由用户确认时,***可允许由用户决定照射。因此,应该注意到***可不允许在这样的确认之前照射。用户然后使用关联的成像和检测器子***进行患者18的成像(框198)。
例如由***(例如,图1和2的***10)进行并且由用户发起(图8的框194)的关联序列200在图9中图示为过程流程图。在用户发起关联序列200后,***10在成像子***30的操作范围内检测一个或多个X射线检测器22(框202)。***10然后可确定每个检测器22的状态(例如,充电状态、当前关联)和/或能力(例如,存储的规程、兼容性)(框204)。当用户指示期望关联那个检测器22或哪些检测器22时,***10形成成像子***20和辨别并且识别的检测器22中的一个或多个之间的唯一关联(框206)。然后指示该关联(框208),例如在一个或多个检测器22上,在成像子***30上等等指示该关联。此外,应该注意到该关联还可在显示器上指示,例如连接到工作站38的显示器40(图2)上。***10然后可提示用户输入以确定是否已经指示正确的关联(框210)。在临时关联被不正确指示的实施例中,序列可提供给***10以重新形成唯一关联(框206)。相反地,在关联被正确指示的实施例中,确认关联(框212)并且实现X射线发射(框214)。
该书面说明使用示例以公开本发明,其包括最佳模式,并且还使本领域内技术人员能够实践本发明,包括制作和使用任何装置或***和执行任何包含的方法。本发明的专利范围由权利要求限定,并且可包括本领域内技术人员想到的其他示例。这样的其他示例如果它们具有不与权利要求的书面语言不同的结构元件,或者如果它们包括与权利要求的书面语言无实质区别的等同结构元件则规定在权利要求的范围内。
