Cardiac motion estimation by joint alignment of tagged MRI sequences
Image registration has been proposed as an automatic method for recovering cardiac displacement fields from tagged Magnetic Resonance Imaging (tMRI) sequences. Initially performed as a set of pairwise registrations, these techniques have evolved to the use of 3D+t deformation models, requiring metrics of joint image alignment (JA). However, only linear combinations of cost functions defined wit...
متن کاملAnalysis of Tagged Cardiac MRI Sequences
The non invasive evaluation of the cardiac function presents a great interest for the diagnosis of cardiovascular diseases. Tagged cardiac MRI allows the measurement of anatomical and functional myocardial parameters. This protocol generates a dark grid which is deformed with the myocardium displacement on both Short-Axis (SA) and LongAxis (LA) frames in a time sequence. Tracking the grid allow...
متن کاملAnalysis of true 3D cardiac motion using 3D tagged MRI
Introduction Tagged MRI offers the possibility to trace tissue deformation by creating planes of MR signal decrease throughout the measured object [1]. This results in dark stripes in the images, referred to as tags. In subsequently acquired time series the tag planes bend out of shape according to the motion of the imaged tissue. Retrospective tracking of the tag surfaces then enables reconstr...
متن کاملModel-based analysis of cardiac motion from tagged MRI data
We develop a new method for analyzing the motion of the left ventricle (LV) of a heart from tagged MRI data. Our technique is based on the development of a new class of physics-based deformable models whose parameters are functions allowing the definition of new parameterized primitives and parameterized deformations. These parameter functions improve the accuracy of shape description through t...
متن کامل2D Motion Analysis of Long Axis Cardiac Tagged MRI
The tracking and reconstruction of myocardial motion is critical to the diagnosis and treatment of heart disease. Currently, little has been done for the analysis of motion in long axis (LA) cardiac images. We propose a new fully automated motion reconstruction method for grid- tagged MRI that combines Gabor filters and deformable models. First, we use a Gabor filter bank to generate the corres...
