Abstract
Magnetic resonance imaging (MRI) uses direct, continuous, unaliased, real-time imaging for motion compensation. Unaliased, real-time two dimensional (2D) images are acquired continuously of the anatomy of interest. The images are compared to at least one template to using a correlation coefficient technique to select images corresponding to minimal motion and distortion. A spatial grid of templates can be used to cover an anatomy of interest. Multiple temporal templates can be used to create a time series of magnetic resonance (MR) images. The selected images are used to provide a high-resolution image, preferably a three dimensional (3D) image.
