Abstract: A system comprises a catheter configured for delivery to a body cavity defined by surrounding tissue; a plurality of ultrasound transducers coupled to a distal end of the catheter; and an electronics module configured to selectively turn on/off each ultrasound transducer according to a predetermined activation sequence and to process signals received from each ultrasound transducer to produce at least a 2D display of the surrounding tissue. A user can selectively calculate and display various aspects of cardiac activity. The user can display Dipole Density (DDM), Charge Density (CDM), or Voltage (V-V). The shape and location of the chamber (surface), and the potentials recorded at electrodes can be displayed. The system can also change back and forth between the different display modes, and with post processing tools, can change how various types of information is displayed. Methods are also provided.

Abstract: Provided are a localization system and method useful in the acquisition and analysis of cardiac information. The localization system and method can be used with systems that perform cardiac mapping, diagnosis and treatment of cardiac abnormalities, as examples, and in the retrieval, processing, and interpretation of such types of information. The localization system and method use high impedance inputs, improved isolation, and relatively high drive currents for pairs of electrodes used to establish a multi-axis coordinate system. The axes can be rotated and scaled to improve localization.

Abstract: Provided is a cardiac virtualization test tank and testing system and method. A test tank is provided that includes a physical heart model representing the structure of the heart and a plurality of electrodes that output simulated biopotential signals based on an EP model representing the electrophysiological activity of the heart. The test system can be used for training, teaching, or validating a cardiac mapping, diagnosis, and/or treatment system, as examples.
