Abstract
Official abstract text for this publication.
An MR imaging system independently manipulates a fat and a water component of MR signals used for generating image data. An RF signal generator and a magnetic field gradient generator provide an RF pulse and magnetic field gradient sequence for acquisition of an MR signal discriminating between anatomical objects based on longitudinal relaxation time (T1). The sequence comprises, a first pulse sequence for selectively inverting a water component of the MR signal substantially exclusively of fat, a first time delay adjustable to discriminate between different anatomical elements, a second pulse sequence having a resonant frequency selected to invert a fat component of the MR signal substantially exclusively of water and a data acquisition magnetic field gradient for acquisition of the MR signal. An image shows enhanced visualization of discriminated anatomical elements.
First claim
Opening claim text (preview).
What is claimed is: 1. An MR (Magnetic Resonance) imaging system for independently manipulating a fat and a water component of MR signals used for generating image data, comprising: an RF (Radio Frequency) signal generator and a magnetic field gradient generator for providing an RF pulse and magnetic field gradient sequence for acquisition of an MR signal discriminating between anatomical objects based on longitudinal relaxation time (T1), said RF pulse and magnetic field gradient…
