    摘要: In one embodiment, a medical analysis system, includes a display, and processing circuitry to receive a three-dimensional map of an interior surface of a cavity within a body of a living subject, positions on the interior surface being defined in a spherical coordinate system wherein each position is defined by an angular coordinate pair and an associated radial distance from an origin, project the angular coordinate pair of respective positions from the interior surface to respective locations in a two-dimensional plane according to a coordinate transformation, compute respective elevation values from the plane at the respective locations based on at least the radial distance associated with the respective projected angular coordinate pair, and render to the display an image of a partially flattened surface of the interior surface with the partially flattened surface being elevated from the plane according to the computed respective elevation values at the respective locations.

    摘要: A radio frequency ablation system, includes a single frequency RF signal generator, control circuitry configured to set phases and amplitudes of a plurality of replicas of the RF signal, a plurality of non-linear amplifiers, configured to amplify the plurality of replicas of the RF signal, and to drive a respective plurality of ablation electrodes in a patient body with the amplified replicas. In a further modification, a processor is configured to receive a superposition of the plurality of replicas as a return signal from a body surface patch electrode, and to adaptively adjust phases and amplitudes of the amplified replicas in response to the return signal with the control circuitry to zero crosstalk currents. In a tissue contact check mode of operation the phases of the amplified replicas are identical, and in an ablation mode of operation the phases of the amplified replicas differ from one another.

    摘要: A method includes receiving an electrocardiogram (ECG) measured at a given location over a portion of a heart. Based on the measured ECG, a rhythmic pattern is identified over a given time-interval. The rhythmic pattern corresponds to a relation between a present cardiac cycle length and a preceding cardiac cycle length. Based on the identified rhythmic pattern, a classification of the location as either showing regular pattern or showing arrhythmia is determined. The location is graphically encoded according to the classification. The graphically encoded location is overlaid on an anatomical map of the portion of a heart.

    摘要: A method includes receiving a plurality of voxel values corresponding to respective locations in a heart, which are acquired using magnetic resonance imaging (MRI). Voxel values that, in spite of (i) corresponding to a same location in the heart and (ii) being gated to a same phase of an electrocardiogram (ECG) cycle of the heart, differ by more than a predefined difference, are identified. An image of at least a portion of the heart is reconstructed from the plurality of voxel values excluding at least the identified voxel values.

    摘要: A medical apparatus includes a shaft, an expandable frame, a membrane, a diagnostic electrode, a reference electrode, and a processor. The shaft is configured for insertion into an organ of a patient. The expandable frame is coupled to a distal end of the shaft. The diagnostic electrode, which is disposed on an external surface of the expandable frame, is configured to sense diagnostic signals when in contact with tissue. The reference electrode is disposed on a surface of the expandable frame directly opposite the diagnostic electrode, wherein the reference electrode is electrically insulated from the tissue and is configured to sense interfering signals.

    摘要: A probe includes an elastic element having first and second ends, a transmitter, one or more receiving antennas and one or more narrow-band amplifiers. The transmitter is coupled to the first end and is configured to transmit signals in a given range of frequencies. The one or more receiving antennas are coupled to the second end and are configured to receive the signals. The one or more narrow-band amplifiers have a pass-band that matches the given range of frequencies and are configured to amplify the signals received by the one or more receiving antennas, respectively.
