The new cleaning method works better than other methods at keeping important anatomical details clear in low-dose CT scans, as shown by higher quality scores in different body parts.
Scientific Claim
The SADiff model outperforms CNN-based and GAN-based methods in preserving fine anatomical details in low-dose CT images, as demonstrated by higher SSIM and FSIM scores across multiple anatomical regions.
Original Statement
“In the Piglet dataset, where high-frequency anatomical details are crucial, diffusion-based models outperform both CNN and GAN counterparts. CoCoDiff and DPM achieve significant improvements, with DPM showing a 4.3% higher SSIM than ResNextify. Nevertheless, SADiff again leads with a 1.6% enhancement in PSNR and a 0.16% increase in SSIM over DPM.”
