Respiratory motion correction in gated cardiac SPECT using quaternion-based, rigid-body registration
In this article, a new method is introduced for estimating the motion of the heart due to respiration in gated cardiac SPECT using a rigid-body model with rotation parametrized by a unit quaternion. The method is based on minimizing the sum of squared errors between the reference and the deformed fr...
