Angle Images using Gabor Filters in Cardiac Tagged MRI

Tagged Magnetic Resonance Imaging (MRI) is a non invasive technique used to examine cardiac deformation in vivo An Angle Image is a representation of a Tagged MRI which recovers the relative position of the tissue respect to the distorted tags Thus cardiac deformation can be estimated This paper describes a new approach to generate Angle Images using a bank of Gabor filters in short axis cardiac Tagged MRI Our method improves the Angle Images obtained by global techniques like HARP with a local frequency analysis We propose to use the phase response of a combination of a Gabor filters bank and use it to find a more precise deformation of the left ventricle We demonstrate the accuracy of our method over HARP by several experimental results
