Researchers have developed EPC-3D-Diff, a new conditional 3D latent diffusion model designed to improve the synthesis of CT images from CBCT data. This model incorporates a physics-derived equivariance loss that ensures consistency between the synthesized 3D volumes and their corresponding 2D projections. By performing diffusion in a compressed latent space, EPC-3D-Diff achieves efficient and stable training, leading to significant improvements in image quality metrics like PSNR and SSIM, as well as enhanced HU accuracy for radiotherapy applications.
