Exploring Dimensions Dataset Dimensions Spatial dimensions (2D slice) Volume Depth Subject ID Longitudinal data Temporal data (fMRI) Different scan modality Clinical Factors (e.g. Age) Parameter sweeps Trying different algorithms … Dorsal-ventral Subject ID
tipiX Demo Slice vs subject number • Lesion • Registration • Difficult registration Groups vs age • Time evolution of vascular disease Slice vs parameter grid • Parameter sweep Slice vs subject number Grid • Original dataset exploration
Features Open source, works directly on modern browser • Processing is client-side Streamlined collaboration: specific tipiX link encodes dataset • Assumes collaborators have data access Many features present and in development • Display volume info, volume control slice:drop binding, website embedding… • Come to the demo!
