ABSTRACT
A gradient calculation module based on high performance DSP was designed to meet the needs of digital MRI spectrometer. According to the requirements of users, this apparatus can achieve rotation transformation, pre-emphasis, shimming and other gradient calculation functions in a single chip of DSP. It then outputs gradient waveform data of channel X, Y, Z and shimming data of channel B0. Experiments show that the design has good versatility and can satisfy the functional, speed and accuracy requirements of MRI gradient calculation. It provides a practical gradient calculation solution for the development of digital spectrometer.
