Abstract
A subject is disposed in an imaging region ( ) of a magnetic resonance imaging apparatus. An operator submits a series of user preferences to the apparatus. A gradient optimizer ( ) generates a gradient waveform that is optimal for the imaging procedure based on the user submitted specifications and the apparatus hardware specifications. The optimizer ( ) accesses a memory that stores ideal gradient waveform models. The model that best fits the user specifications is selected and digitized ( ). The digitized waveform is then convolved ( ) with a band-limited kernel ( ) that represents a frequency spectrum ( ) of a gradient amplifier ( ), producing a gradient waveform ( ) that is smooth and does not exceed the capabilities of the amplifier. This optimized waveform is used in an imaging process including a collected data reconstruction portion of the process.
