The appropriate positioning of a patient in an X-Ray imaging system can present difficulties for medical professional owing, on one hand to the small size of important anatomical aspects which need tobe captured in X-Ray images, and on the other hand to the significant movements in a field of view presented by a typical patient. The present application proposes to obtain an image of the positionof a patient in the field of view at approximately the same time that an initial X-Ray image is obtained. If it proves necessary to obtain a subsequent X-Ray image with updated field of view settings(for example, collimation parameters), the movement of the patient at the point of taking the second image is factored into the provision of updated field of view settings. 患者在X射线成像系统中的适当定位能够存在针对医学专业人员的困难，一方面是由于需要在X射线图像中捕获的重要解剖学方面的小尺寸，并且另一方面是由典型患者呈现的视场中的显著移动。本申请提出在获得初始X射线图像的大致相同时间获得视场中患者的位置的图像。如果证明有必要获得具有经更新的视场设置的后续X射线图像(例如，准直参数)，则拍摄第二图像的点处患者的移动被考虑到经更新的视场设置的提供中。
