    摘要： An example method includes receiving monitoring data representing one or more substantially real time electrical signals based on measurements from one or more respective electrodes. The method also includes selecting at least one signal of interest (SOI) from the monitoring data, each selected SOI being associated with a respective anatomical location and storing SOI data in memory corresponding to each selected SOI. The method also includes quantifying changes between signal characteristics of real time signals acquired for one or more respective anatomical locations and the at least one SOI that is associated with each of the respective anatomical locations. An output can be generated based on the quantifying to characterize spatially local signal changes with respect to each of the respective anatomical locations.

    摘要： This disclosure relates to localization and tracking of an object. As one example, measurement data can be stored in memory to represent measured electrical signals at each of a plurality of known measurement locations in a given coordinate system in response to an applied signal at an unknown location in the given coordinate system. A dipole model cost function has parameters representing a dipole location and moment corresponding to the applied signal. A boundary condition can be imposed on the dipole model cost function. The unknown location in the given coordinate system, corresponding to the dipole location, can then be determined based on the stored measurement data and the dipole model cost function with the boundary condition imposed thereon.

    摘要翻译： 本公开涉及对象的定位和跟踪。 作为一个示例，可以将测量数据存储在存储器中，以响应于在给定坐标系中的未知位置处施加的信号，在给定坐标系中的多个已知测量位置中的每一个处表示测量的电信号。 偶极子模型成本函数具有表示与施加的信号相对应的偶极子位置和时刻的参数。 可以对偶极子模型成本函数施加边界条件。 然后，可以基于所存储的测量数据和其上施加边界条件的偶极子模型成本函数来确定给定坐标系中与偶极子位置对应的未知位置。

    摘要： A method may include storing electrical measurement data and geometry. One or more boundary conditions can be determined based on supplemental information associated with at least one selected location associated an anatomic envelope within a patient's body. Reconstructed electrical activity can be computed for a plurality of locations residing on the anatomic envelope within the patient's body based on the electrical data and the geometry data, the least one boundary condition being imposed to improve the computing.
