Quadtrees are everywhere spatial data exists. Mapping services use quadtree-like tile pyramids to serve map tiles at different zoom levels (Bing's quadkey system, for example, addresses tiles as base-4 paths). Game engines use them for collision detection and visibility culling. Geographic information systems use spatial indexes to store and query spatial datasets. PostGIS uses GiST indexes (R-tree-style) for spatial queries on geometries, while PostgreSQL's core supports quadtree-like SP-GiST indexes for certain data types like points.
临床数据也印证了这一点。2月12日，BridgeBio Pharma公布的3期顶线结果显示，Infigratinib以每年平均生长2.1厘米达到了显著的治疗效果，且无严重毒性反应、无副作用退出事件出现。
