Characteristics of motion artifacts in cardiac optical mapping studies

Motion artifacts are one of the issues in cardiac optical mapping studies. This paper is focused on the description of the motion artifacts caused by planar movement. The theory of its origin and possibilities of its suppression is described. The suppression of the motion artifacts is based on image registration techniques. There are introduced the characteristics about influence of the weighted area averages on presence of these artifacts. In this study conventional pharmacological or mechanical ways of motion artifacts suppression were not involved.
