AI images realistic enough to support research into brain diseases
Scientists have developed an AI model that renders three-dimensional, synthetic images of the human brain that are realistic and accurate enough to use in medical research.
Developed at King’s College London in collaboration with University College London, the model and images have helped scientists better understand what the human brain looks like, supporting research to predict, diagnose and treat brain diseases including dementia, stroke, and multiple sclerosis.
The algorithm was created using the UK’s most powerful supercomputer - NVIDIA Cambridge-1 – which allowed researchers to train the AI in weeks rather than months and produce images of far higher quality.
According to King’s, the high-resolution 3D images have all the characteristics of real human brains, such as correct folding patterns and regions of the right size. It can also accurately produce images that reflect clinical factors like age, sex or disease status.
Data produced by the model was realistic enough to replicate human anatomy; the team showed that a dementia research study running on real data would show the same outcomes as a study running on generated synthetic data.
