  • Publication number: 20230412151
    Abstract: A hybrid filter circuit for reducing common-mode interference signals with frequencies of at least 150 kHz in a power line with at least one phase. The circuit has a passive filter stage and an active filter unit with an active filter stage. The circuit can be coupled to an electrical device on a load side and to a power supply system on a supply side via the power line. The first active filter stage includes a sensor for measuring a common mode noise signal in the power line and a feedback unit with an active amplifier unit for generating a compensation signal counteracting the common mode noise signal, which is coupled into the power line via an output of the first active filter stage. The passive filter stage and the active filter circuit are arranged in cascade between the load terminal and a supply terminal.

  • Publication number: 20130129174
    Abstract: 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.
