Streak artifact prediction

An image processing system, comprising an input port (IN) for receiving a projection image of an object. The image is acquired by a rotational image apparatus (IM) at a position on an imaging trajectory in an adjustable rotation plane (Pi) around an imaging region. An image artifact extent predictor...

More Information
Summary:An image processing system, comprising an input port (IN) for receiving a projection image of an object. The image is acquired by a rotational image apparatus (IM) at a position on an imaging trajectory in an adjustable rotation plane (Pi) around an imaging region. An image artifact extent predictor (AP) of the system is configured to predict for said image a projection area of a reconstruction artifact. A visualizer (VIZ) is configured to visualize, on a display unit (MT), said image with a visual indication of the projection area. 种图像处理系统，包括用于接收对象的投影图像的输入端口(IN)。由旋转图像装置(IM)在围绕成像区域的可调节旋转平面(π)中的成像轨迹上的位置处采集图像。系统的图像伪影范围预测器(AP)被配置为针对所述图像预测重建伪影的投影区。可视化器(VIZ)被配置为在显示单元(MT)上利用投影区的视觉指示来可视化所述图像。
