A cost effective console, compatible with Pulseq-GPI has been designed for 9.5mT using general purpose microcontroller boards. Data from Pulseq-GPI was extracted in a text file and uploaded on the microcontroller to play the gradient waveforms (Gx, Gy) and radio frequency (RF) pulses, with a dwell time of 5us. Current work involves integration of Analog to Digital Convertor (ADC) for Gradient Recalled Echo (GRE) sequence and reducing the time required to upload the waveforms for the entire sequence. Future work involves interfacing the console with coil driver apparatus to integrate with 9.5mT lab MRI systems.
