一种定位三维CT图像中的目标的方法和安检系统
摘要：
公开了一种定位三维CT图像中的目标的方法和安检系统。该方法包括：显示一幅三维CT图像；接收用户在第一视角下对所述三维CT图像的至少一个区域的选择，产生第一三维描述；接收用户在第二视角下对所述三维CT图像的至少一个区域的选择，产生第二三维描述，其中第一视角和第二视角之间的角度在预定的范围之中并且所述第一三维描述和所述第二三维描述与相应视角下目标的尺寸、位置或者物理属性中的至少之一相关；以及基于所述第一三维描述和所述第二三维描述确定所述三维CT图像中的目标。利用上述方案，能够方便用户迅速标记CT图像中的嫌疑物。
摘要（英）：

The invention discloses a method for positioning a target in a three dimensional CT image, and a security inspection system. The method comprises the following steps: displaying the three dimensional CT image; receiving a user's choice of at least one area in the three dimensional CT image in a first visual angle to generate a first three dimensional description; receiving a user's choice of at least one area in the three dimensional CT image in a second visual angle to generate a second three dimensional description, wherein an angle between the first visual angle and the second visual angle is in a preset range, and the first three dimensional description and the second three dimensional description are related with at least one of the dimension, the position and physical properties of the target in a corresponding visual angle; and determining the target in the three dimensional CT image based on the first three dimensional description and the second three dimensional description. The method adopting the above scheme allows a suspicion object in the CT image to be rapidly marked by the user.
