Abstract

The subject invention pertains to a method and apparatus for enhanced multiple coil imaging. The subject invention is advantageous for use in imaging devices, such as MRIs where multiple images can be combined to form a single composite image. In one specific embodiment, the subject method and apparatus utilize a novel process of converting from the original signal vector in the time domain to allow the subject invention to be installed in-line with current MRI devices.
