AI algorithm produces synthetic brain MR images

An artificial intelligence (AI) algorithm can produce synthetic brain MR images, solving a number of challenges in training AI algorithms, according to research presented at the International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI) in Granada, Spain.

Researchers from NVIDIA, Massachusetts General Hospital and Brigham and Women’s Hospital in Boston, and the Mayo Clinic in Rochester, MN, have trained a type of AI algorithm called a generative adversarial network (GAN) to generate synthetic abnormal brain MR images. These synthetic images could be used to augment a small dataset or even on their own to train a deep-learning algorithm, according to Hoo-Chang Shin, a senior research scientist at NVIDIA.
