Patent ID: 8633695

Claim:
A magnetic resonance imaging (MRI) system, comprising: a magnetic resonance imaging scanner comprising: a main magnet providing a substantially uniform main magnetic field B 0 for a subject under observation; and a radio frequency (RF) coil configured to irradiate a radio frequency (RF) pulse into a region of interest of said subject under observation, wherein said RF pulse is a resultant pulse including a summation of a first base pulse comprising a first adiabatic pulse and a second base pulse comprising a second adiabatic pulse, wherein said RF pulse selectively suppresses magnetic resonance signals from more than one chemical component or more than one spatial region within said region of interest of said subject under observation, and wherein said first adiabatic pulse is characterized by a first amplitude modulation function and a first frequency modulation function, and said second adiabatic pulse is characterized by a second amplitude modulation function and a second frequency modulation function.
