SAMRI-3D 适配 SAM2 用于 3D MRI 分割，性能优于先前模型

作者 PulseAugur 编辑部 · [2 个来源] ·

研究人员推出了 SAMRI-3D，这是一个用于 3D MRI 分割的新基准和方法，它适配了 Segment Anything Model 2 (SAM2)。该方法通过仅微调解码器和内存模块，将分割精度与之前的基于 SAM 的医学模型相比显著提高，达到了 0.76 的平均 Dice 分数。该方法还引入了具有截断符号距离场 (TSDF) 目标的全局体积令牌 (GVT)，以更好地处理 MRI 扫描中的不可见边界，从而在不同数据集上以最小的方差实现了 0.78 的整体准确率。 AI

影响 增强医学影像分割能力，可能提高放射科诊断的准确性和效率。
