AI 摘要
RibAssist 3D 是一个开源研究原型,用于从 CT 衍生的正位和侧位投影中进行双平面肋骨骨折检测、解剖定位和选择性 3D 定位。研究发现,跨视角对应是主要瓶颈,而非几何或检测问题。在保守策略下,系统在 601 处骨折中正确定位了 15 处,中位误差 1.49 毫米,93% 肋骨精确,但端到端提交率仅 2.50%。该研究建立了可复现的选择性 3D 定位框架,并公开了代码和演示。

RibAssist 3D: Biplanar Rib-Fracture Detection, Addressing, and Selective 3D Localization from CT-Derived Projections Abstract Cross-view pairing of rib fractures in orthogonal CT projections enables accurate 3D localization, but correspondence confidence remains the primary bottleneck. Rib fractures are common and time-consuming to localize on computed tomography (CT). We ask whether fractures detected independently in two orthogonal CT-derived projections (anteroposterior and lateral) can be pa
