Cardiac mapping system with efficiency algorithm

A cardiac information processing system, comprising:

• a catheter including an array of electrodes having a known spatial configuration in three-dimensional space and a plurality of ultrasound transducers configured to record cardiac activity data over multiple cardiac cycles, including electrical activity data and wall position data;
• and
• a cardiac information console, comprising:
• a signal processor configured to:
• perform an inverse solution using Singular Value Decomposition to calculate sets of cardiac activity data at a plurality of time intervals using the recorded cardiac activity data;
• process the electrical activity data to determine discrete time segments representing phases of the multiple cardiac cycles, by determining a time index that is a unique phase of the cardiac cycle and segmenting data between each sequential pair of time indices into a predetermined number of time segments;
• segment the wall position data into datasets, wherein each dataset comprises a set of points representing at least a portion of a cardiac surface during one of the discrete time segments;
• aggregate the wall position data and segment the aggregated wall position data into multiple bins, each bin including anatomic data from one of the discrete time segments;
• when there are more or less discrete time segments than the number of bins, adjust the recorded cardiac activity data to account for the difference;
• create an anatomic foundational model from cardiac activity data from a single bin representing a single discrete time segment;
• and
• generate anatomic models representing the remaining bins based on the foundational model using a conformal mesh, wherein the signal processor is configured to project each vertex of the foundational model along its normal axis, inward and outward, and to adjust each vertex along a projection to match at least approximately the cardiac activity data in subsequent bins, thereby creating anatomic models representing the cardiac activity data in each bin based on the foundational model;
• and
• a user interface module configured to display a beating anatomic model of at least one cardiac chamber as a sequence of the generated anatomic models.
