The application of multilevel B-splines in 3D emulation of dynamic epicardium mapping / 中国医疗器械杂志

ABSTRACT

This paper presents an algorithm for data interpolation and approximation used in the whole atria mapping. Multilevel B-splines are introduced to compute the whole atria surface through a set of irregularly spaced points and to draw the 3D isopotential map, which can reflect the conduction process of depolarization in complex arrhythmia such as atrial fibrillation.
