Abstract
The present disclosure relates to an SGM-based LDCT denoising neural network apparatus, wherein the apparatus comprises an input unit receiving an LDCT image, a score model unit processing the LDCT image at each time step by constructing a score-based generative model pre-trained to remove noise from the LDCT training image, an image adjustment unit adjusting noise characteristics of the LDCT image by utilizing the LDCT image at a reference time step through the score-based generative model and generating a noise-fitted LDCT image, a denoising unit progressively removing noise from the noise-fitted LDCT image through iterative input and output operations for each reverse time step of the score-based generative model, and a noise-reconstructed image output unit outputting a noise-reconstructed image generated based on the noise-fitted LDCT image.
