Abstract
The present disclosure is directed to merging data acquired from differently configured catheters on a common map. In use, physical characteristics of catheters influence recorded electrical signals/responses such that differently configured catheters (e.g., different electrode sizes, shapes, materials, spacings, etc.) may record different responses to measurements taken at the same location in response to the same excitation signal. To allow merging of data from differently configured catheters in a common map, the present disclosure applies a corrective coefficient or transfer function to the recorded electrical signals of one or both catheters to counter-balance variable influences of catheter specific characteristics on recorded signals.
