摘要： A method and system for intraoperative guidance in an off-pump mitral valve repair procedure is disclosed. A plurality of patient-specific models of the mitral valve are generated, each from pre-operative image data obtained using a separate imaging modality. The pre-operative image data from the separate imaging modalities are fused into a common coordinate system by registering the plurality of patient-specific models. A model of the mitral valve is estimated in real-time in intraoperative image data using a fused physiological prior resulting from the registering of the plurality of patient-specific models.

摘要： A method and system for model-based fusion of multi-modal volumetric images is disclosed. A first patient-specific model of an anchor anatomical structure is detected in a first medical image acquired using a first imaging modality, and a second patient-specific model of the anchor anatomical structure is detected in a second medical image acquired using a second imaging modality. A weighted mapping function is determined based on the first patient-specific model of the anchor anatomical structure and the second patient-specific model of the anchor anatomical structure using learned weights to minimize mapping error with respect to a target anatomical structure. The target anatomical structure from the first medical image to the second medical image using the weighted mapping function. In an application of this model-based fusion to transcatheter valve therapies, the trachea bifurcation is used as the anchor anatomical structure and the aortic valve is the target anatomical structure.

摘要： A system acquires images in the presence of a contrast agent of relatively long persistence using a synchronization processor, image acquisition device and imaging controller. The synchronization processor provides an image acquisition trigger signal for acquiring images at a particular point within both a cardiac and a respiratory cycle in response to signals representing cardiac and respiratory cycles. The image acquisition device includes an assembly comprising a radiation emitter and detector rotatable about a patient for acquiring images of a portion of patient anatomy at different angles. The imaging controller initiates acquisition of data representing multiple images in the presence of a contrast agent of relatively long persistence by repetitively, initiating rotation of the assembly to an angle, acquiring an image at the angle in response to the trigger signal and incrementally increasing the angle.

摘要： The present invention relates to a method for assisting with percutaneous interventions, wherein 2D x-ray images of an object region are recorded before the intervention using a C-arm x-ray system or a robot-based x-ray system at different projection angles and 3D x-ray image data of the object region is reconstructed from the 2D x-ray recordings. One or more 2D or 3D ultrasound images are recorded before and/or during the intervention using an external ultrasound system and registered with the 3D image data. The 2D or 3D ultrasound images are then overlaid with the 3D image data record or a target region segmented therefrom or displayed next to one another in the same perspective. The method allows a puncture or biopsy to be monitored with a low level of radiation.
