摘要： A diagnostic imaging system (10) corrects metal artifact streaks (38) emanating from a metal object (36) in a tomographic image (T). A first processor (40) reduces streaks (38) caused by mild artifacts by applying an adaptive filter (82). The filter (82) is perpendicularly oriented toward the center of the metal object (36). The weight of the filter (82) is a function of the local structure tensor and the vector pointing to the metal object (36). If it is determined that the strong artifacts are present in the image, a second processor (48) applies a sinogram completed image algorithm to correct for severe artifacts in the image. The sinogram completed image and adaptively filtered image are fused to a final corrected image. In the fusion process, highly corrupted tomographic regions are replaced by the result of the sinogram completed image and the remainder is replaced by the adaptively filtered image.

摘要： Systems and methods for facilitating visual detection of one or more catheter tips in relation to the morphology of an anatomical structure—in real-time—are provided. The disclosed systems and methods are particularly useful for locating reference catheters relative to heart tissue using an automated navigation support that draws upon prominent image features that are visible in the x-ray fluoroscopy images. According to exemplary embodiments, prominent features include one or more catheter tips of reference catheter(s) that are typically placed at known standard positions in relation to the anatomical structures. Based on the noted prominent features, the systems and methods of the present disclosure are effective in achieving alignment of the anatomical structures, e.g., the heart morphology, with the interventional devices, e.g., ablation catheter(s) introduced by the physician, and generating a fused or overlaid image. Advantageous computer software products are also disclosed.

摘要： Systems and methods for data acquisition in computed tomography (CT) applications are provided. The systems and methods are particularly adapted for scanning and acquiring/processing data in connection with high-power cone-beam CT applications. The electron beam is moved/scanned along the anode surface to multiple focal positions. Data acquisition for a full projection at one focus position and one view angle is achieved by activating each focus position multiple times during the data acquisition for one angle of the gantry. The detector array and associated data processing system are adapted to rapidly switch between the different focus positions during the acquisitions for one view angle and to collect all data belonging to the same projection into the same data set. Adaptive electron optics are utilized to move/scan the electron beam along the anode surface to the various focus positions. Alternatively, a plurality of cathodes may be provided for respective focus positions and the system may support fast switching therebetween to achieve desirably short spot times. The disclosed CT system permits greater power densities without risk of heat damage to the anode and effectively increases the track velocity of the electron beam on the anode surface. The CT system and associated data acquisition methods have particular utility in CT applications requiring increased time resolution and/or spatial resolution, e.g., cardiac CT applications.

摘要： In real-time three-dimensional imaging the choice of the visualization method and orientation is crucial for intervention success. The key question is what to ignore and what to show in real-time applications, where user control is not appropriate. The invention addresses this problem by visualizing an intervention (caused by a user) to an object of interest without the requirement of an interactive input by the user. Advantageously, according to an exemplary embodiment of the present invention, parameters for a visualization procedure are automatically chosen during data acquisition which may allow for an efficient tracking of the actual orientation and relative position of the structure with respect to the object of interest.

摘要： The invention relates to a device and a method for displaying a vessel (2) with the aid of intravascular ultrasound images (1). A sequence of intravascular ultrasound images (I(E,x)) is generated by means of a probe (5) and stored in a memory (10) in a manner indexed by the associated location (x) where they were generated and also the associated heartbeat phase (E) and/or breathing phase. During a subsequent medical intervention, those ultrasound images (I1,12,13) which best correspond to the heartbeat phase of a current fluoroscopic image (At) or belong to the current stopping location of a catheter (13) can be selected from the memory (10) and displayed on a monitor (12).

摘要： The invention relates to an imaging (X-ray) system for observing the motion of an object in the vascular system of a body volume (10). An X-ray apparatus (3) in this system generates two-dimensional projection images (4) of the body volume (10). In a module (5) the position of the tip of the object is determined from the projection images and this position is associated, in a further module (2), with a previously acquired three-dimensional representation (1) of the vascular system. The module (2) then calculates optimum imaging parameters which involve notably a planar projection of the tip of the object and a minimum projection window. These parameters are subsequently set on the X-ray apparatus (3) so as to serve as a basis for the next two-dimensional image (4).

摘要： The invention relates to a method of determining a corresponding image of a moving object for a reference image from an image sequence which represents the motion as a sequence of states of motion. To this end, two motion signals, representing the development of the relevant motions, are examined for similarities. Using the similarity function thus obtained, that image in the image sequence can be determined which represents at least approximately the state of motion of the object which is represented in the reference image. Furthermore, the invention relates to a system which is suitable for carrying out the method as well as to a computer program and a computer program product enabling a data processing unit to carry out the method.
