摘要： The invention addresses the problem of correctly positioning a catheter and reducing radiation doses. It relates to an X-ray imaging system (1) for a robotic catheter, comprising said catheter (3), and a processing unit (5) for receiving X-ray images of a patient environment (15). By being adapted to receive one or more auxiliary information items and using said information for determining the catheter position, the processing unit does not entirely have to rely on a large number of scanned image data, thus helping to reduce radiation while correctly delivering the catheter position as a function of as few as a single image, preferably 2D, and said one auxiliary information items. Further, said processing unit allows for at least one of rendering an image and provide said image to a visualization device (21), and providing feedback, e.g. steering commands, to said robotic catheter.

摘要： 2D images are registered with 3D volume data. In order to provide 2D/3D registration with a facilitated workflow 3D volume data (112) of an object, having a frame of reference is received. A transformation plane (116) is defined in relation to the 3D volume data. A 2D image of the object with an image plane is received. The transformation plane is projected on the image plane. The frame of reference is aligned with the 2D image. At least one alignment interaction value (128) is projected (130) on the transformation plane to determine (134) at least one transformed interaction value (132). The frame of reference is translated with the at least one transformed interaction value.

摘要： 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 (π) 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.
