Transient gradient waveform errors can degrade MRI quality. This work presents an automatic implementation of gradient waveform predistortion, which has been applied to half-pulse excited 2D-ultrashort echo time imaging. The predistortion method reliably improves image quality and quantification of ultrashort T₂ species by reducing out-of-slice signal that contaminates half-pulse excited images.
