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 utility model relates to a method for shooting a locating plate, a computer program, and a system for shooting an X-ray image. The invention is based on the idea of automatically controlling the quality of a locating plate of a patient (5). The locating plate is shot by a CT device (7) having an X-ray emitter (8) and an X-ray detector (9). To this end, a body part of the patient is selected, a first locating plate segment of the selected body part is shot, and a boundary marker inside or on the body of the patient (5) is automatically sought in the first locating plate segment. Selection of the body part to be shot and searching of the boundary marker in the first locating plate segment allow automatic quality control of the first locating plate segment in an automatic evaluation manner, thereby avoiding further using of incomplete or wrong locating plates, especially for calculation of X-ray dose (14) for diagnostic CT shooting.
