Description
技术领域
本发明涉及一种X-射线摄像设备,该X-射线摄像设备被构造为利用透过被摄体的X-射线束而产生被摄体的X-射线图像。
背景技术
传统上,在医疗领域使用一种用于产生被摄体的三维截面图像的计算机断层摄像(CT)设备。为了获得三维截面图像,在从被摄体的外周放射到被摄体的放射线(radiation)在通过被摄体之后被检测并且转换为图像信号。然后,通过重构处理,图像信号被转换为三维截面图像。
螺旋扫描CT设备是现在一般使用的一种设备。螺旋扫描CT设备构造成:构成一对的辐射源和辐射检测器以被摄体的虚拟体轴为转动轴线绕被摄体螺旋状转动,以检测在多个位置处的透过的放射线的强度。
另一方面,近年来,已经开发了一种CT设备,在该CT设备中,使布置在固定的辐射源和固定的辐射检测器之间的被摄体转动,以产生断层图像。该类型的CT设备包括作为辐射检测器的二维平面传感器。通过将锥形放射线束照射到被摄体,该CT设备可以通过单次扫描产生在重构三维图像中必需的荧光图像。此外,该CT设备不需要被摄体在体轴方向上连续运动,该连续运动是普通的CT设备所必需的。
在日本特开2005-205082号公报中论述了一种在拍摄被摄体图像的同时转动被摄体的设备。根据该设备,确认被摄体的安全、然后在被摄体的位置稳定后转动被摄体是重要的。如今正在开发满足上述需求的CT设备。
日本特开2005-205082号公报中论述了在拍摄被摄体图像的同时转动被摄体的摄像方法。此外,在日本特开2005-205082号公报中论述的设备具有确保被摄体的安全和在摄像过程中所要求的稳定被摄体在转动期间的姿势的能力。
例如,日本特开2006-43193号公报论述了一种设备,在该设备中,在转动平台上设置用于控制被摄体的身体运动的支撑构件。采取半蹲姿态的被摄体由转动平台上的该支撑构件支撑。此外,日本特开2005-205082号公报中论述的CT设备在被摄体的前方设置下肢防护装置。利用该防护装置,防止了在转动期间被摄体的下肢接触被摄体周围的非转动部分。通过转动被摄体而不是转动辐射源和检测器,可以提高CT图像的拍摄量。因此,在胸部检查(chest screening)的领域,CT图像正在取代普通的静像。
此外,为了保护被摄体的安全,在日本特开2006-43193号公报中论述的CT设备检测支撑被摄体的构件的状态,并且根据检测结果控制转动台的转动。
然而,由于上述摄像设备的辐射检测器是大尺寸的二维平面传感器,这些摄像设备通常较贵。此外,从有效地使用医院中有限的安装空间的观点考虑,对于能够拍摄两种不同类型的图像即CT图像和普通静像的X-射线摄像设备的需求正在增加。日本特开2005-205082号公报中论述了这种摄像设备。当使用该摄像设备拍摄静像时,通过将被摄体支撑构件从X-射线放射的范围移走而在转动平台上制造空间。
在利用该摄像设备拍摄CT图像中,被摄体优选布置在紧靠近X-射线摄像单元的位置,只要被摄体在转动期间不接触X-射线摄像单元。这有助于提供更宽的重构区域,此外,有助于降低图像模糊的可能性。因此,与日本特开2005-205082号公报中论述的X-射线摄像单元相比,在实际的摄像中,将X-射线摄像单元设置在更靠近被摄体的位置是必要的。
在实际的摄像中,如图5所示,在被摄体暴露于从X-射线管1辐射的X-射线束的状态下,坐在转动台2上的被摄体P的下肢Pa经过X-射线摄像单元3附近。此外,如果在被摄体P的前方设置下肢防护装置4,则下肢防护装置4将与下肢Pa一起在X-射线摄像单元3的下方转动。因此,在拍摄CT图像时,X-射线摄像单元3需要被布置在摄像范围L1内。
另一方面,在拍摄静像中,如在日本特开2005-205082号公报中论述的那样,由位于被摄体支撑构件下方的移动单元将被摄体支撑构件从摄像区域移走,并且被摄体被移动到更接近X-射线摄像单元的位置。然后,在被摄体与X-射线摄像单元的外部完全接触的状态下进行摄像。
另一方面,要求CT设备能够拍摄更宽范围的普通静像,例如,被摄体从头部到下肢的整个身体。这是因为当病人经受初步医学检查时,通常拍摄静像。因此,与拍摄CT图像时相比,在拍摄静像的情况下,要求X-射线摄像单元3在更宽的范围上下移动。
然而,如果X-射线摄像单元3被构造成覆盖用于静像的宽移动范围,则X-射线摄像单元3趋于在对于CT摄像来说超出必要的范围移动。例如,如果将X-射线摄像单元设在对于CT图像来说不合适的低位置,则在转动期间被摄体支撑构件或被摄体P的下肢Pa可能接触X-射线摄像单元3。为了确保安全,需要在设定X-射线摄像单元3的位置时加以注意。结果,降低了X-射线摄像设备的操作容易性。
当摄像模式改变时,出现类似的问题。如果由X-射线摄像单元3在较低位置拍摄普通静像,然后该模式改变到CT模式并且移动被摄体支撑构件,如果转动台2在不改变被摄体的位置的情况下转动,则被摄体P的下肢Pa可能接触X-射线摄像单元3。在该情况下,如上所述,降低了安全性。
此外,关于包括平面传感器的被摄体转动CT摄像设备,不要求被摄体沿着体轴方向移动,该移动在普通的螺旋扫描CT设备中是必要的。相反地,在CT摄像期间,需要从一定高度从不同角度拍摄图像。因此,如果包括高度可调节的X-射线摄像单元的摄像设备在CT摄像期间上下移动X-射线摄像单元,则不能获得正确的图像,因而重构变得困难。由于传统的设备不包括防止在转动期间的上下移动的方法,因而存在X-射线摄像单元在摄像期间上下移动的可能性。
发明内容
本发明旨在提供一种X-射线摄像设备,该X-射线摄像设备既能够拍摄CT图像也能够拍摄普通静像,并且可用于在不降低X-射线摄像单元的垂直位置设定的操作性和不降低安全性的情况下,产生用于诊断的有效图像。

根据本发明的另一个方面,一种X-射线摄像设备,其包括:X-射线摄像装置;转动装置,其用于使X-射线摄像装置绕转动轴线相对于被摄体转动;支撑装置,其用于支撑被摄体;以及限制装置,其用于根据支撑装置相对于转动轴线的位置限制X-射线摄像装置沿着转动轴线移动的范围。

具体实施方式
现在将参考附图详细地说明本发明的各个示例性实施例、特征和方面。
第一示例性实施例
图1图解了根据本发明的示例性实施例的在CT摄像模式中的X-射线摄像设备的构造,其中,在摄像期间使被摄体(P)转动。在X-射线管11的前方,布置有面对X-射线管11的例如平面传感器等X-射线摄像单元13。在转动台12上的被摄体P被布置在X-射线管11与X-射线摄像单元13之间。转动台12可以转动360度。X-射线摄像单元13通过滑动单元14被可移动地安装到支柱15。由上下驱动单元16上下驱动滑动单元14。可以由摄像单元位置检测器17来检测X-射线摄像单元13的最低位置。
转动台12由转动驱动单元18支撑。被摄体P就坐的椅子19、被摄体P的背部所压靠的靠背20和用于保护被摄体P的下肢Pa的下肢防护装置21被布置在转动台12上。
在转动台12的转动轴线C的附近设置椅子19。在被摄体P坐在椅子19上的状态下,被摄体P将背部压靠着靠背20。靠背20在垂直方向上较长,其截面呈圆弧状,使得被摄体P可容易地使背部压靠着靠背20。用于保护被摄体P的带子22和把手23被设置联接到靠背20。靠背20在水平方向上的位置被设成使得当被摄体P压靠靠背20时,被摄体P的虚拟体轴与转动台12的转动轴线C基本上同轴。
下肢防护装置21呈圆弧状,使得其与转动台12的圆弧形状相配。设置下肢防护装置21来保护被摄体P的下肢Pa,以免在转动过程中下肢Pa接触转动台12周围的非转动部分。
可以由椅子滑动构件24和靠背滑动构件25将构成被摄体支撑构件的椅子19和靠背20从CT摄像位置移出到摄像范围外的位置。因此,静像拍摄不会受到被摄体支撑构件的干扰。由椅子位置检测器26和靠背位置检测器27来检测椅子19和靠背20的位置。
控制X-射线摄像设备的控制单元31被连接到产生从X-射线管11发出的X-射线束的X-射线产生装置32、上下驱动单元16、转动驱动单元18、以及捕捉由X-射线摄像单元13拍摄的图像的摄像单元33。此外,控制单元31被连接到摄像单元位置检测器17、椅子位置检测器26、靠背位置检测器27、以及脚踏开关34。摄像单元33的输出被输入到图像处理单元35。
滑动单元14由上下驱动单元16驱动沿着支柱15在垂直方向上上下移动X-射线摄像单元13。基于控制单元31的根据例如操作者对脚踏开关34的操作的指示,由上下驱动单元16进行驱动控制。此外,不论X-射线摄像单元13的垂直位置是否在CT摄像的CT摄像范围L1内,该位置由摄像单元位置检测器17来检测。检测结果被发送到控制单元31。CT摄像范围L1的最低位置被设定为预定高度,使得被摄体支撑构件的下肢防护装置21不进入摄像区域,并且使得被摄体P的下肢Pa不接触X-射线摄像单元13。
由作为支撑构件位置检测单元的椅子位置检测器26和靠背位置检测器27检测将要拍摄CT图像还是静像。检测结果被发送到控制单元31。
在拍摄CT图像时,控制单元31根据摄像请求信号驱动转动驱动单元18和控制转动台12的转动。当转动台12到达预定的转动状态时,开始来自CT摄像的C-射线管11的X-射线照射。在该状态下,即使操作脚踏开关34,控制单元31也不会上下移动X-射线摄像单元13并且将X-射线摄像单元13保持在该位置。这样,可以获得从很多方向拍摄的位置图像。
与该照射同步地,控制单元31控制摄像单元33,使得穿过被摄体P的X-射线被X-射线摄像单元13捕捉以作为图像数据。图像处理单元35处理从围绕被摄体的所有方向拍摄的图像数据,并且重构三维断层图像。
控制单元31可以设成使得不论是否放射X-射线束,X-射线摄像单元13在转动台12转动的情况下不上下移动。
图2是在静像拍摄模式中X-射线摄像设备的构造的俯视图。转动台12从图1所示的状态顺时针转动90度,椅子19和靠背20的位置从CT摄像期间的位置改变。图3是图2所示状态下的X-射线摄像设备的构造的侧视图。由于分别由椅子滑动构件24和靠背滑动构件25使椅子19和靠背20沿圆周方向在转动台12上移动,因而当摄像时,被摄体P的身体可完全接触X-射线摄像单元13。
从X-射线管11放射的X-射线束经过椅子19和靠背20之间并且被照射到被摄体P上。在该情况下,由于照射未被干扰,因而可以拍摄从被摄体P的头部到下肢Pa的整个身体的任意部分的图像。根据X-射线摄像单元13的摄像范围L2的位置来拍摄图像。
在拍摄被摄体P的下肢Pa的静像中,X-射线摄像单元13可设定在低位置。即使在完成静像的拍摄之后椅子19和靠背20被改变到CT摄像模式,X-射线摄像单元13仍在用于拍摄静像的位置。如果转动台12在该状态下转动,则例如下肢Pa可能撞到X-射线摄像单元13。然而,根据本发明示例性实施例,消除了这种可能性。
椅子19和靠背20的位置到用于CT摄像的位置的改变由椅子位置检测器26和靠背位置检测器27检测。椅子19和靠背20的位置改变的信号被发送到控制单元31。即使当控制单元31接收到该信号时,摄像单元位置检测器17检测并且发送表示X-射线摄像单元13不在CT摄像位置的信号。在该状态下,控制单元31控制转动台12,使得即使操作者给出移动转动台12的指示,转动台12也不转动。同时,在显示单元中(未示出)显示表示X-射线摄像单元13需要被移动的标记。
在该状态下,控制单元31仅允许X-射线摄像单元的向上移动。当操作者使用脚踏开关34向上移动X-射线摄像单元、并且X-射线摄像单元13在用于CT摄像的CT摄像范围L1内移动时,显示单元上的标记消失。作为选择地,X-射线摄像单元13可被控制成使得当标记显示时,X-射线摄像单元13自动地移动到CT摄像范围L1的最低位置。这样,可以防止当将静像拍摄模式改变到CT摄像模式时产生的问题。
图4是图解X-射线摄像单元13的上下位置的调整的流程图。在步骤S1中,为了调整X-射线摄像单元13的位置,操作者操作脚踏开关34。在步骤S2中,控制单元31基于来自椅子位置检测器26和靠背位置检测器27的信号确定椅子19和靠背20的被摄体支撑构件是否在CT摄像位置。
如果CT摄像设备在如图1所示的CT摄像位置(步骤S2中的”是”),那么根据步骤S3-S6,只要来自摄像单元位置检测器17的信号表示X-射线摄像单元13在CT摄像范围L1内,则控制单元31根据脚踏开关34的操作允许X-射线摄像单元13的上下移动。在步骤S7中,当X-射线摄像单元13到达期望位置时,操作者从脚踏开关34移走他的脚,并且在步骤S8中停止上下移动。
然而,如果控制单元31确定为X-射线摄像单元13已经到达CT摄像范围的最高或最低位置(步骤S4中的”是”),则在步骤S8中,控制单元31控制X-射线摄像单元13停止在该位置,并且不进行进一步的上下移动。这样,X-射线摄像单元13在CT摄像模式期间将一直设定在CT摄像范围L1中。
此外,如果被摄体支撑构件在如图2和3所示的静像拍摄模式中(步骤S2中的”否”),则在步骤S9和S10中,控制单元31控制X-射线摄像单元13,使得与来自摄像单元位置检测器17的信号无关地根据来自脚踏开关34的输入而进行X-射线摄像单元13的上下移动。这样,X-射线摄像单元13在静像拍摄期间能够在如图3所示的宽的静像摄像范围L2(比L1大)内移动。因此,可以拍摄被摄体P的从头部到下肢Pa的整个身体的图像。
根据本发明示例性实施例的X-射线摄像设备,既可以拍摄CT图像也可以拍摄普通静像。另外,可以在不降低安全性和设定X-射线摄像单元的垂直位置的操作性的情况下获得诊断用的有效图像。
虽然已经参考示例性实施例说明了本发明,应该理解的是,本发明不限于公开的示例性实施例。所附权利要求书的范围应符合最宽的解释,以包含所有变形、等同结构和功能。
