Gamma regularization based reconstruction for low dose CT.
Reducing the radiation in computerized tomography is today a major concern in radiology. Low dose computerized tomography (LDCT) offers a sound way to deal with this problem. However, more severe noise in the reconstructed CT images is observed under low dose scan protocols (e.g. lowered tube current or voltage values). In this paper we propose a Gamma regularization based algorithm for LDCT im...
متن کاملUltra-Low Dose CT Image Reconstruction Based on Big Data Priors
1 Executive summary This project will develop a dramatically improved approach to low-dose X-ray CT image formation by extracting and using information from a big-data corpus of regular dose CT images. X-Ray Computed Tomography (CT) provides high-resolution images of anatomical structures for diagnosis and management of human diseases and disorders. For example, CT has had a tremendous impact o...
متن کاملVariational Bayesian blind restoration reconstruction based on shear wave transform for low-dose medical CT image
A variational Bayesian blind restoration reconstruction based on shear wave transform for low-dose medical computed tomography (CT) image is proposed. The proposed algorithm eliminates the effects of the point spread function in the process of low-dose medical CT image reconstruction and improves the reconstructed image quality. The shear wave transform is used to sparsely represent the CT imag...
متن کاملDatabase-assisted low-dose CT image restoration.
PURPOSE Acquiring data for CT at low radiation doses has become a pressing goal. Unfortunately, the reduced data quality adversely affects the quality of the reconstructions, impeding their readability. In previous work, the authors showed how a prior regular-dose scan of the same patient can efficiently be used to mitigate low-dose artifacts. However, since a prior is not always available, the...
