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...
Optical mapping using membrane potential-sensitive fluorescent dyes provides a means of recording electrical activation on the heart surface with high spatial resolution. However, in order to interpret these data, it is necessary to correct for artifact introduced by heart wall motion. This paper describes a novel image registration technique that enables electrical activity on the heart surface to...
High-dimensional deformable registration of MRI brain images is presented here. The deformation is driven by local forces estimated from point similarities based on joint histogram and with the use of prior information obtained from tissue probability maps available in selected commonly used brain atlases. Three point similarity measures are tested in an experiment with data obtained from standard...
