Dictionary generation for Magnetic Resonance Fingerprinting (MRF) can be a computationally intensive procedure, especially as complexity and density increase. Conveniently, the majority of operations required for calculating dictionary entries are already enumerated in conventional computer graphics shader packages. Here, we leverage the decades of research and hardware development spent to improve computer graphics optimization to remove the need for CUDA parallelization and instead directly render MRF dictionaries into compressible video files in virtually real time.
