Evaluation of Rigid and Non-rigid Motion Compensation of Cardiac Perfusion MRI

Abstract: Abstract. Although the evaluation of cardiac perfusion using MRI could be of crucial importance for the diagnosis of ischemic heart diseases, it is still not a routinely used technique. The major difficulty is that MR perfusion images are often corrupted by inconsistent myocardial motion. Although motion compensation methods have been studied throughout the past decade, no clinically accepted solution has emerged. This is partly due to the lack of comprehensive validation. To address this deficit we collected … Show more

“…Aside from through-plane motion, rigid techniques do not consider deformations that can occur in the myocardium throughout the first-pass image acquisition. Registration methods that use a global (affine) motions model [15] account for some aspects of the more complex deformations. Non-rigid motion models that account for local deformations [16]–[18] provide better alignment if there is deformation of the heart during breathing, but they are more susceptible to noise and are more computationally intensive.…”

“…Techniques by Bidaut and Vallé [11], and Gupta et al [12] are based on the sum-of-squared differences metric, which is well-suited to correcting for rotations [19]. Other groups have employed metrics based on normalized mutual information [15], and cross-correlation [12]. Other methods move away from the intensity-based approach and use metrics that assess spatial gradients [20] or independent component analysis [21].…”

“…In order to successfully apply the KLT filter to clinical perfusion datasets with significant myocardial motion, we hereby propose to apply non-rigid registration to compensate for respiratory motion and myocardial deformation between image frames. This novel combined approach of non-rigid registration prior to filtering is expected to improve the effectiveness of KLT filtering by concentrating the information content into a smaller number of eigenimages [11]. …”
