| 1. A method of examining an object using magnetic resonance, said method comprising the steps of:
subjecting said object to a constant magnetic field;
exciting atoms in said object within said constant magnetic field with a radio frequency waveform created from a modified
Bessel function; and
measuring relaxation magnetic resonance signals emitted from said atoms,
displaying an image associated with said relaxation magnetic resonance signals,
wherein said radio frequency waveform is created by a step selected from the group consisting of:
modifying a Bessel function to have a greater number of lobes than an unmodified version of said Bessel function,
multiplying a modified Bessel function with a time-varying function, and
superimposing a second modified Bessel function on a first modified Bessel function.
