用于X射线图像的自动质量控制
摘要：
本发明涉及一种定位片的拍摄方法、一种计算机程序以及一种用于拍摄X射线图像的系统。本发明基于自动控制患者（5）的定位片的质量的思路，所述定位片通过包括X射线发射器（8）以及X射线探测器（9）的CT设备（7）拍摄。为此，选择患者的身体部位，拍摄选择的身体部位的第一定位片片段，并且在所述第一定位片片段中自动查找在患者（5）的身体内或身体上的界标。待拍摄的身体部位的选择和然后在第一定位片片段中对界标的查找使得可以实现以对第一定位片片段的自动评估形式的自动质量控制，由此避免了进一步使用不完整的或错误的定位片，特别是用于计算对于诊断的CT拍摄的射线剂量（14）。
摘要（英）：

The method involves recording an image of a patient (5) lying on a patient couch (6) by a stationary digital camera (31), and selecting a body part of the patient. A start position of the couch is computed based on the position of the selected body part, and an X-ray image portion of the selected body part is recorded. The image portion is automatically searched for identifying a landmark in or at the body of the patient. The image portion is automatically evaluated. Length of the image portion is automatically computed in dependence of the selected body part of the patient. Independent claims are also included for the following: (1) a computer program product for performing a method for recording an X-ray image (2) a machine-readable medium comprising a computer program product for performing a method for recording an X-ray image (3) a system for recording an X-ray image.
