Title:
DUAL RESOLUTION DIXON MAGNETIC RESONANCE IMAGING
Document Type and Number:
WIPO Patent Application WO/2019/137932
Kind Code:
A1
Abstract:
The invention provides for a magnetic resonance imaging system (100). Machine executable instructions (140) cause a processor controlling the magnetic resonance imaging system to control (200) the magnetic resonance imaging system with the pulse sequence commands to acquire two point Dixon magnetic resonance data and single point Dixon magnetic resonance data; calculate (202) a first resolution magnetic field inhomogeneity map (148) using the two point Dixon magnetic resonance data; calculate (204) a second resolution magnetic field inhomogeneity map (154) by interpolating the first resolution magnetic inhomogeneity map to the second resolution; and calculate (206) a second resolution water image (156) and a second resolution fat image (158) using the single point Dixon magnetic resonance imaging data and the second resolution magnetic field inhomogeneity map. The first resolution is lower than the second resolution.
