GaSpCT: Gaussian Splatting for Novel CT Projection View Synthesis

Understand

We present GaSpCT, a novel view synthesis and 3D scene representation method used to generate novel projection views for Computer Tomography (CT) scans.

• We adapt the Gaussian Splatting framework to enable novel view synthesis in CT based on limited sets of 2D image projections and without the need for Structure from Motion (SfM) methodologies.
• Therefore, we reduce the total scanning duration and the amount of radiation dose the patient receives during the scan.
• We adapted the loss function to our use-case by encouraging a stronger background and foreground distinction using two sparsity promoting regularizers: a beta loss and a total variation (TV) loss.
