Abstract
In a method for designing a selective RF pulse for a magnetic resonance apparatus, a desired excitation spectrum of the RF pulse is prescribed, a time function is formed by Fourier transformation of the excitation spectrum, a part is selected from the time function that, proceeding from a region around the zero point of the Fourier transformation, extends in a direction, and the selected part is designed to substantially convert to zero at least in the aforementioned region.
Claims10
A method for designing a selective RF pulse for use in a magnetic resonance apparatus, comprising the steps of:
- prescribing an excitation spectrum for an RF pulse;
- forming a time function by Fourier transformation of said excitation spectrum;
- selecting a part of said time function proceeding in a direction from a region around a zero point of said Fourier transformation;
- and
- designing said selected part to steadily convert to zero at least in said region.
