Researchers have introduced GSToken, a novel method for representing 3D medical images, specifically multi-modal MRI scans for brain tumor recognition. Unlike existing approaches that compress images into sequences of tokens while discarding spatial information, GSToken embeds explicit geometric properties such as a 3D center, scale, and orientation within each token. This geometric encoding significantly enhances the information density of volumetric representations. The effectiveness of GSToken was demonstrated through a frozen-token utility evaluation protocol, where it consistently outperformed capacity-matched baselines across various tumor sub-regions and metrics.
