Scribble: Optimised Segmentation of Medical Images through AI

Summary: A semi-automated, artificial-intelligence based, interactive method for selecting a structure in a medical image, that requires only limited input from the users. What Segmentation is used extensively in medical imaging to highlight specific structures (e.g. an organ, a blood vessel or a tumour) and locations that should be...

Patient-Specific Brain Networks from BOLD-fMRI

Summary: A method for analysing functional magnetic resonance (fMRI) images to identify brain networks in task and resting-state experiments. What Blood-oxygen-level dependent functional MRI (BOLD-fMRI) measures change in neuronal activity by detecting alterations in brain blood oxygenation. High oxygenation levels are associated with increased...
