$K$-NeAS advances multi-material CT reconstruction with neural SDFs

By PulseAugur Editorial · [1 sources] ·

Researchers have developed $K$-NeAS, a novel architecture for scalable multi-material CT reconstruction. This system utilizes neural signed distance functions (SDFs) and a Gaussian Mixture Model (GMM) to automate attenuation bounding, eliminating manual tuning. $K$-NeAS can model an arbitrary number of overlapping tissues and has demonstrated superior 3D volumetric fidelity, particularly in complex multi-tissue regions like the abdomen, outperforming existing single-material baselines.

    $K$-NeAS: Scalable Multi-Material CT Reconstruction Using Neural SDFs

    arXiv:2607.14415v1 Announce Type: new Abstract: Computed Tomography (CT) carries significant ionizing radiation risks, driving the need for sparse-view reconstruction. Implicit scene representations (ISRs) address this by recovering continuous volumetric attenuation fields direct…
