高斯溅射

CT 中的高斯溅射是指把体数据表示为一组显式的三维高斯基元，每个基元有位置、形状和密度，并优化这些基元，使其渲染出的 X 射线投影与测量一致。它改编自用于照片新视角合成的三维高斯溅射，把发射与遮挡模型换成了适合透射成像的衰减模型。

与隐式神经表示相比，显式基元在 GPU 上光栅化很快，逐扫描重建可以从数小时缩短到数分钟，而且表示会把细节集中在物体需要的地方。目前主要用于稀疏视角 CT 和 CBCT，并已扩展到 4D 呼吸成像和金属伪影校正。

关键技术问题包括：让溅射积分对层析足够精确、处理位姿误差、从 FBP 或学习先验初始化，以及扩展到大体积数据。这里的论文从 X 射线新视角合成一直覆盖到精确且可扩展的层析建模。
