Motivation: LLMs possess remarkable ability to process and generate sequential data which can be used to generate MRI pulse sequences.
Goal(s): Train a custom implementation of Generative Pre-trained Transformer (GPT) to generate MRI pulse sequences.
Approach: Pseudo random version of sequences like FLASH were generated to create training set which were then tokenized through a custom tokenizer with reduced vocabulary size. These tokenized sequences were used to train a custom implementation of GPT.
Results: GPT was able to learn the sequence structure and generate out-of-data pseudo random sequences that can be simulated to get a reconstruction.
Impact: This shows the capability of LLMs to generate MRI sequences. Which then can be fine-tuned with a differentiable simulator to adjust the sequence towards desired imaging objectives.
