PT Unknown AU Joel Barajas Jaume Garcia Francesc Carreras Sandra Pujades Petia Radeva TI Angle Images Using Gabor Filters in Cardiac Tagged MRI BT Proceeding of the 2005 conference on Artificial Intelligence Research and Development PY 2005 BP 107 EP 114 DE Angle Images; Gabor Filters; Harp; Tagged Mri AB 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. PI Amsterdam, The Netherlands ER
