1 results about "Low dose ct" patented technology

The application discloses an edge enhancement-based low-dose CT image denoising system and method, and belongs to the field of medical image processing. The system comprises a feature extraction module, an encoder, a decoder and an image reconstruction module. In the encoder and the decoder, each encoding layer and each decoding layer comprises a multi-domain feature module. The multi-domain feature module comprises a local feature modeling unit, a state space modeling unit and a multi-domain feature fusion unit. The local feature modeling unit is used for performing convolution operation on the input feature to obtain a local feature. The state space modeling unit is used for performing feature extraction on the input feature through a state space model to obtain a global feature, and after extracting an edge feature, the two are fused into an edge enhancement global feature. The multi-domain feature fusion unit is used for fusing the local feature and the edge enhancement global feature. The application can improve the noise suppression effect of the low-dose CT image, and significantly improve the structure consistency and edge retention capability of the denoised image.
