Summary: | Motion estimation and correction is an important yet challenge problem in medical image analysis. This paper presents a new approach to estimate and correct motion artifacts in cardiac perfusion image sequences. The method uses a modified optical flow and block-matching technique to estimate the velocity vector between consecutive image frames. The displacement field of each image is corrected and deformed according a total velocity. This technique is applied to sequences of magnetic resonance myocardial perfusion images. Results from quantitative error measurement and time-intensity plots show improvements over original images after the use of this technique. |
