Short acquisition time is essential in cardiac cine magnetic resonance imaging (MRI), in particular for sick patients who have difficulties to hold their breath. This paper investigates the use of two reconstruction methods, initially proposed for static images, for reconstructing cardiac cine images from partial k-space. A new acquisition schema which makes use of temporal redundancies within data is proposed. The results show that, in comparison with the full k-space acquisition, the acquisition time can be reduced by a factor of 4 while obtaining a good reconstruction quality.
