Spectral Component Imaging Using Phased Array Coils
US Patent:
6177795, Jan 23, 2001
Filed:
May 19, 1998
Appl. No.:
9/080920
Inventors:
Gang Gary Zhu - Fort Collins CO
Jian Huang - Fort Collins CO
Hari Hariharan - Fort Collins CO
Stephen J. Freeland - Fort Collins CO

Assignee:
Elscint Ltd. - Haifa
International Classification:
G01V 300
US Classification:
324307
Abstract:
A method of using magnetic resonance imaging (MRI) systems for acquiring separate data contributions in images of subjects derived from at least a first and a second spectral components, the method comprising: applying RF pulses; receiving RF signals with a phased array coil arrangement having a plurality of segments; acquiring two initial complex images, the first of the two initial images being a complex image of each of the spectral components in phase; the second of the two initial images being a complex image of each of the spectral components out of phase, the first of said two initial complex images ostensibly being a plus image, and the second of said two complex images ostensibly being a minus image initially; and matching the ostensible plus and minus images so that the first complex images and the second complex images are grouped together for further processing. Preferably, a two-point Dixon method is used to generate the components.
Spectral Component Separation Including Unwrapping Of The Phase Via A Poisson Equation Utilizing A Weighting Map
US Patent:
5701074, Dec 23, 1997
Filed:
Apr 25, 1996
Appl. No.:
8/639330
Inventors:
Gang Zhu - Fort Collins CO
Assignee:
Eiscint Ltd. - Haifa
International Classification:
G01R 3346
US Classification:
324307
Abstract:
A method of phase unwrapping by solving the Poisson equation using a weighted iterative algorithm, for use when separating spectral component with magnetic resonance imaging systems. The solution of the Poisson equation is expedited by using a weighting matrix obtained by calculating the average noise level of an in-phase image and using 3-5 times the noise level as a threshold with only pixel intensity levels above the threshold being set equal to one and the other pixels being set to zero. The pixels on the weight matrix are also set to zero according to the size differences of the phase offset per pixel either in the row or column direction. The solution of the Poisson equation is then uniquely operated on to remove a constant (bias) and to improve the fit.
