    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: During catheter or guide wire intervention, a road map of, for example, the coronary vessel tree based on pre-interventional angiograms is displayed. This road map, however, is naturally static and hence not consistent with the instantaneous heart and respiration cycles in the life image, which may be displayed on the screen next to the road map. According to an exemplary embodiment of the present invention, images of a series of x-ray images of an object of interest are determined, where the object of interest is not sufficiently filled with the contrast agent. Advantageously, these images may be used to provide for an improved road map.

    摘要: The invention relates to a device and a method for providing an angiographic image (A) based on a database (2) with angiograms (3, 3a) from various heartbeat phases (H) and respiratory phases (R). From the available angiograms (3, 3a), a function (f) is first calculated, which describes the position (x) of the heart (1) dependent upon the respiratory phase (R). With the aid of this function (f) an angiographic image (A) may be generated which matches the heartbeat phase (Hd) and the respiratory phase (Rd) for given values of the heartbeat phase (Hd) and the respiratory phase (Rd), by transformation of an available angiogram (3a) which matches the heartbeat phase (Hd).

    摘要: The invention relates to a device and to a method for combining two images, especially for superimposition of static vascular maps (B), which were taken at different phases of the cardiac cycle and/or the respiratory cycle and were archived in a memory (6), on a current image (A) of a catheter (2, 8) in the vascular system (9). In the method, a defined section of a map image (B) around the estimated actual position of the catheter is selected and is displayed superimposed on the current image (A) in an image (C) on a monitor (10). The map image (B) used for this is preferably selected by means of an electrocardiogram to match the particular cardiac cycle. The position of the catheter relative to the map image (B) can be estimated using a distance image (D).

    摘要: Linking of interventional and real time ultrasonic information with nonereal time anatomical information of, for example, a vessel or a tumor vascularization provided by x-ray rotational angiography requires high computational performance. According to an aspect of the present invention, an ultrasonic reference image is calibrated with respect to a high quality image acquired by a different imaging system. Then, during operational intervention, a registration or calibration of a data set acquired during the intervention is performed with respect to the reference image and not (as in state of the art devices) to the high quality image. Advantageously, this may allow for a fast fusion of the high quality image with the real time images and therefore allow for an improved tracking of operational interventions performed on a patient.

    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.
