摘要： Prior to an intervention, a 3D rotational scan is acquired (at block 10) in respect of a body volume and reconstructed. In addition, three-dimensional image data in respect of the body volume is acquired (at block 12) using another modality, such as computerised tomography (CT) or magnetic resonance (MR), reconstructed, and prepared for visualisation. During the actual intervention, live two-dimensional fluoroscopic images are acquired (at block 14), using the imaging system employed to acquire the 3D rotational scan, and processed for visualisation. The 2D image data is registered (at block 16) to the 3D rotational image data acquired and reconstructed in respect of the body volume of interest, and then a 3D-3D registration process is employed (at block 18) to register the 3D image data acquired in respect of the same body volume using, for example, CT or MR imaging systems to the 3D rotational image data, and a display module (20) is used to align the 2D fluoroscopic image and the 3D MR/CT image as a fused or composite image and display the image.

摘要： The present invention describes a method for rendering and displaying a curved planar reformat (CPR) view (7') of a blood vessel's 3D tubular structure (1), wherein the viewing direction of the curved planar reformat view (7') is coupled to the viewing angle on a segmented or raw representation of the 3D tubular structure's ren- dered voxel volume to be visualized or, alternatively, to the C-arm geometry of a 3D rotational angiography device's C-arm system (6). The proposed method thus enables measurements on the X-ray image which do not suffer from spatial foreshortening and do not need to be calibrated. Thereby, said coupling can be performed bidirectional. According to a first aspect of the proposed method, this means that the viewing direction of the aforementioned curved planar reformat view (7') follows the viewing angle on a segmented or raw representation of the 3D tubular structure's rendered voxel volume to be visualized, or vice versa. According to another aspect of the proposed method, this means that the viewing direction of the curved planar reformat view (7') is set depending on the C-arm geometry given by the roll (?x ), pitch (? y ) and yaw angle (?z ) of a 3D rotational angiography device's C-arm system (6), or vice versa.

摘要： The invention relates to a method and an examination apparatus (10) for the observation of a catheter (43) in a vessel system. First, a 3D model of the vessel system is reconstructed with the help of differently oriented X-ray projections (P 1 A , ...) generated by a C-arm system (20) during the injection of a contrast agent. Next, a movement corridor (M) of the catheter (43) is determined from the 3D model. During an examination procedure, current projections (P) are generated showing an image (43') of the catheter that can be registered with the reconstructed 3D model and/or the movement corridor (M). Based on the known current location (43") of the catheter in the 3D model of the vessel geometry or the movement corridor (M), an optimal projection direction (d opt ) can be determined and assumed by the C-arm system (20) for the next projections to be generated.

摘要： To reduce the contrast fluid and X-ray load on patients during interventional procedures, a real-time visualisation architecture is proposed to combine 2D live images with 3D reconstructed volume information. In general, 2D X-ray images are recorded from below (Posterior Anterior) and presented head up (Anterior Posterior) by applying a mirroring operation on the image data. In order to ensure a correct alignment of the 2D live images within the reconstructed 3D volume, as is proposed to display the 3D information under the same inverse viewing angle as the 2D live images by applying a mirroring around the Y-axis to the 3D information and by presenting the 3D information in a reverse sorting order. Furthermore, transparent surface/volume rendering may be combined with silhouette rendering to maintain the contrast in the 2D information while preserving the 3D impression.

摘要： The invention provides a system (102) for accurately detecting a patient's (114) movement during imaging procedures. The system comprises a camera (126) for providing a stream of camera images of a part of a patient's exterior (206). The system (102) furthermore comprises a fiducial element (116), which fiducial element (116) is mountable on said part of the patient's exterior (206), and which fiducial element (116) is detectable in the stream of camera images, and an image processor (128) for detecting a displacement of the fiducial element based on consecutive camera images comprised in at least the stream of camera images and for generating an output signal (129) indicative for said displacement. Herein, the fiducial element (116) has an in-plane stiffness which is substantially larger than an in-plane stiffness of said part of the patient's exterior. In addition, the fiducial element (116) and said part of the patient's exterior are provided with substantially equal outer in-plane dimensions.

摘要： A method and a device for use in conjunction with an imaging modality (202), for controlling the angular orientation of a needle-shaped object (212) while moving it along a path (214) from a given entry point to a given target point in a body during a percutaneous intervention. The device comprises a support unit (502, 602, 702, 802) for supporting a guiding unit (506, 706), which support unit provides a pair of parallel control planes (604, 606) which are at least partially detectable by the imaging modality. The guiding unit establishes a guiding axis (612, 818) substantially perpendicular to the pair of parallel control planes along which guiding axis the needle-shaped object is translatable. The angular orientation of an imaging plane (204) applied by the imaging modality determines a reference for the angular orientation of the pair of parallel control planes. By aligning the pair of parallel control planes with the imaging plane, the guiding axis is in correlation with the path from the entry point to the target point.
