1. A method comprising:

  • processing information related to characteristics of catheter shape;

    measuring first signals before treatment at catheter electrodes at each of multiple, different positions of a catheter in a heart cavity in response to electrical activity in the heart cavity;

    determining first physiological information at multiple locations of an endocardium surface based at least in part on the first signals and catheter shape information provided by the processing of the information related to the characteristics of the catheter shape;

    measuring second signals at the catheter electrodes after the treatment;

    determining second physiological information based at least in part on the second signals and the catheter shape information; and

    displaying a difference map including information about changes, from the first physiological information to the second physiological information, that occurred in response to the treatment.
