Abstract
X光架装置包括：一副可调整角度的平行四边形机构，它由两条与回转主轴中心线平行的平行构件和两根与中心轴线垂直的横柱组成，在两平行构件的悬伸端上分别装有辐射源和辐射线接收器。两根横柱分别配置在通过中心轴线的中心平面的两侧，两平行构件的悬伸端都向中心线的同一侧偏移，使病床的另一侧不再像以前的X射线检查装置那样受平行构件悬伸端的阻碍。平边四边形机构的不平衡量经计算后由放在中心平面另一侧的柱内的重锤平衡。
Description
本发明关于X光架装置。
美国专利No.3892967描述了由两根横柱加两根水平臂构成的可调角度的平行四边形机构的两水平臂末端分别装有X射线辐射源和接收器的装置。该平行四边形机构可绕机座上的回转主轴的轴线回转。两水平臂的悬伸端相对平行四边形与回转主轴中心线形成的平面有一定的偏移，且平行四边形机构相对于回轴主轴的轴线能稳定地保持平衡。医生工作时必须接近躺在回转中心轴线处的病人，当平行四边形机构围绕中心轴线旋转时机构上无论那一个偏移端都会阻碍医生的通路，甚至会碰撞医生。
本发明的目的是提出保证医生至少能从一边靠近病人，并且使医生被碰撞的危险减少到最低的程度，而同时使带有X射线辐射源和接收器的平行四边形机构保持平衡。
本发明的X射线装置包括一个安装在机座上绕中心轴旋转的回转主轴;一副可调整角度的由两根与中心轴线平行的构件和两根与中心轴线垂直的构件组成的平行四边形机构;和分别安装在两根与中心轴线平行的构件端部的辐射源和辐射接收器。该装置的特点是和中心轴线垂直的构件分别配置在中心轴线的两边，且前述的两平行构件的悬伸端均向中心轴线的同一侧偏移一定距离。
图1为装有X射线辐射源和接收器的机器的立体示意图。
图2和3是分别说明X射线辐射源和接收器的安装位置的顶视图。
如图所示为对定卧在可透过辐射线的病床T上的病人作X射线检查
的装置。如图1所示病床T上的病员的心脏位置正好在对称中心C处，对称中心C是本装置的回转中心轴线A1与X射线管23和放射线图象接收器22间形成的放射线轴心线A2的交点。除人的器官外其他对象也可以进行检查。放射线接收器22可以是一块放射线感光胶片、一块萤光屏或一个闪光计数器。总之，要求被检查的对象应位于放射线轴心线A2的对称中心C处。放射线轴心线A2是与X射线管23和图象接收器22所联成的轴线相吻合的。在研究神经和心脏的图象时是将X射线管23和图象接收器22绕中心轴线A1回转（即围绕病员长轴方向在360°范围内回转），斜置成一定角度来进行放射学检查的。它也可以沿病人从头到脚的方向，绕与中心轴线A1垂直的通过对称中心C的另一轴心线回转到90°的范围。放射线轴线A2绕对称中心转成的角度就是在360°范围内绕中心轴线A1回转和沿病人的从头到脚的方向旋转所合成的某一固定角度。
能摆角度的这种X射线装置有一个装牢在医院或实验室地板上的重的机座1，回转主轴2支承在机座上的转动轴承1B上。第一根横柱3一般是与回转主轴2垂直的，用轴销在4处与回转主轴2铰接。第二根横柱5置于回转主轴2的左端用轴销在7处与回转主轴2连接。两根横柱3和5与另两根上、下配置的水平臂8和9分别用支承销10、11、12和13铰接起来形成一副可调整角度的平行四边形机构（3、5、8、9），它的四边在各连接销（10、11、12、13）之间的长度是固定的。
两水平臂8和9在平行四边形以外的延长部分8A和9A，要有足够的延长距离让病床T和病人P能置于紧靠横柱5的地方。图象接收器22和X射线管23分另由两个轴销17和21与延长臂8A和9A的悬伸端连接。横柱5上端延伸出的短柱部分5A有铰接点14与连杆15连接，连杆15伸到图象接收器Ⅰ处由铰接点16连接。同样，第二根连杆19由铰接点18与横柱5连接，而另一端由铰接点（图上未标注）与X射线管23连接。
按本发明所述，横柱3和5是配置在回转主轴2（即中心轴线A1）两
侧的。水平上臂8的悬伸端8B跟水平下臂9的悬伸端9B一样均向回转主轴2（即中心轴线A1）的同侧偏移一定距离。用计算过的重块W置于横柱3中以补偿悬伸端偏于同侧的不平衡状况。因为两水平臂的端部均偏向同一侧，而另一侧（即左侧）无论是在病床T之上或病床T之下均无障碍，也就是说在另一侧无偏移障碍不会碰撞医生。
