FPGA-based acceleration of MRI registration: an enabling technique for improving MRI-guided cardiac therapy
Background Quantification of edema and scar maps with cardiac MR images (cMRIs) enables effective Radiofrequency Ablation (RFA) of arrhythmias during the Electrophysiology (EP) procedure [1]. This demonstrates the paramount advantage over the EP catheterization under X-ray and ultrasound guidance. High-contrast and resolution cMRIs can be obtained preoperatively as a EP roadmap for surgical pla...
متن کاملA technique for improving 2D X-ray to 3D MRI registration in fluoroscopy-guided orthopedic interventions
Introduction Orthopedic interventions are often performed using x-ray fluoroscopic guidance. Although boney structures can be seen on fluoroscopic images, soft tissue contrast in such images is poor. In addition, fluoroscopy can only provide 2-dimensional projection images, which has no spatial resolution along the projection axis. For these reasons it would be beneficial to use preoperative 3D...
متن کاملAxial Cardiac MRI Registration
This paper focuses on finding techniques that can be used in cardiac magnetic resonance images semiautomatic registration in a simple and fast way. The suggested technique depends on using parts of one image selected by the user to be matched with another image of the same patient in order to find control points or correspondences between those two images. The experiment focuses on three techni...
متن کاملMRI-guided gene therapy.
MRI has the ability to generate high-contrast and high-resolution images, to obtain multiple diagnostic evaluations of organ function and morphology, and to provide multiple image planes with no risk of ionizing radiation. Recent efforts have focused on using MR technology to monitor gene delivery, to enhance gene transfection/transduction, and to track gene expression. This review summarizes t...
متن کاملModel-based registration for dynamic cardiac perfusion MRI.
PURPOSE To assess the accuracy of a model-based approach for registration of myocardial dynamic contrast-enhanced (DCE)-MRI corrupted by respiratory motion. MATERIALS AND METHODS Ten patients were scanned for myocardial perfusion on 3T or 1.5T scanners, and short- and long-axis slices were acquired. Interframe registration was done using an iterative model-based method in conjunction with a m...
