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.
运动伪影是心脏光学标测研究中的问题之一。本文着重描述由平面运动引起的运动伪影。阐述了其产生的原理以及抑制的可能性。运动伪影的抑制基于图像配准技术。介绍了加权区域平均对这些伪影存在的影响特征。本研究未涉及传统的抑制运动伪影的药理学或机械方法。
