US Patent:
20130304407, Nov 14, 2013
Filed:
May 8, 2013
Appl. No.:
13/890058
Inventors:
CHARULATHA RAMANTHAN - SOLON OH, US
PING JIA - SOLON OH, US
QINGGUO ZENG - SOLON OH, US
VENKATESH VASUDEVAN - BEACHWOOD OH, US
MARIA STROM - MORELAND HILLS OH, US
RYAN BOKAN - LAKEWOOD OH, US
REMI DUBOIS - MERIGNAC, FR
Assignee:
CARDIOINSIGHT TECHNOLOGIES, INC. - CLEVELAND OH
International Classification:
G01R 25/00
US Classification:
702 72
Abstract:
A computer-implemented method can include determining an amplitude for each of a plurality of input channels, corresponding to respective nodes. A measure of similarity can be computed between the input channel of each node and the input channel of its neighboring nodes. The method can also include comparing an amplitude for each node relative to other nodes to determine temporary bad channels. For each of the temporary bad channels, a measure of similarity can be computed between the input channel of each node and the input channel of its neighboring nodes. Channel integrity can then be identified based on the computed measures of similarity.

RAJA GHANEM - LADERA RANCH CA, US
TIMOTHY G. LASKE - SHOREVIEW MN, US
International Classification:
A61B 5/04
A61B 5/044
Abstract:
For example, one or more non-transitory computer-readable media includes executable instructions to perform a method. The method includes defining a plurality of spatial regions distributed across a geometric surface. At least one wave front that propagates across the geometric surface is detected based on electrical data representing electrophysiological signals for each of a plurality of nodes distributed on the geometric surface over at least one time interval. An indication of conduction velocity of the wave front is determined for at least one spatial region of the plurality of spatial regions during the time interval based on a duration that the wave front resides within the at least one spatial region. Slow conduction activity is identified for the at least one spatial region based on comparing the indication of conduction velocity relative to a threshold. Conduction data is stored in memory to represent each slow conduction event.

SONIYA BHOJWANI - CLEVELAND OH, US
International Classification:
G01B 7/00
A61B 5/06
Abstract:
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.

International Classification:
A61B 5/04
A61B 5/0452
A61B 5/044
Abstract:
One or more non-transitory computer-readable media have instructions executable by a processor and programmed to perform a method. The method includes analyzing the electrical data to locate one or more wave front lines over a given time interval. The electrical data represents electrophysiological signals distributed across a cardiac envelope for one or more time intervals. A respective trajectory is determined for each wave end of each wave front line that is located across the cardiac envelope over the given time interval. A set of connected trajectories are identified based on a duration that the trajectories are connected to each other by a respective wave front line during the given time interval. A connectivity association is characterized for the trajectories in the set of connected trajectories.
