Abstract
A method for improving the imaging quality of magnetic resonance imaging (MRI) equipment and MRI equipment, include obtaining a corresponding relationship between a deterioration factor of imaging quality and the cumulative energy of gradient pulses applied by successive scanning MRI sequences, then determining a predicted value of a current deterioration factor of imaging quality according to the currently applied cumulative energy of the gradient pulses and said corresponding relationship, adopting a corresponding method to carry out dynamic regulation or compensation using the predicted value of said deterioration factor of imaging quality as a reference, so as to cancel the influence produced by the heating effect of the gradient system to the imaging quality, thereby effectively improving the imaging quality of the MRI equipment.
