Efficient low-dose CT artifact mitigation using an artifact-matched prior scan.
PURPOSE Low-dose CT has attracted increasing attention due to growing concerns about radiation exposure in medical scans. However, the frugal use of x-ray radiation inevitably reduces the quality of the CT images, introducing artifacts such as noise and streaks which make the reconstructed images difficult to read in clinical routine. For follow-up CT exams a prior scan is often available. It t...
متن کاملProgram Tailoring: Slicing by Sequential Criteria (Artifact)
Protocol and typestate analyses often report some sequences of statements ending at a program point P that needs to be scrutinized, since P may be erroneous or imprecisely analyzed. Program slicing focuses only on the behavior at P by computing a slice of the program affecting the values at P . In our companion paper “Program Tailoring: Slicing by Sequential Criteria”, we propose to focus on th...
متن کاملArtifact Reduction by Target-Driven Reconstruction
Introduction Magnetic Resonance Spectroscopic Imaging (MRSI) is a powerful technique to gain insight into physiological processes in the human body. Since 2D MRSI examinations typically last excessively long, the use of acceleration techniques is of great importance. Here, we use a SENSE approach [1, 2, 3]. The Spatial Response Function (SRF) indicates which spatial areas contribute to the fina...
متن کاملA New Method for Metal Artifact Reduction in CT Scan Images
Introduction In CT imaging, metallic implants inside the tissues cause metal artifact that reduce the quality of image for diagnosis. In order to reduce the effect of this artifact, a new method with more appropriate results has been presented in this research work. Materials and Methods The presented method comprised of following steps: a) image enhancement and metal areas extraction, b) sinog...
متن کاملThe development of induction within natural kind and artifact categories.
Recent studies have shown that children as young as age 3% use category membership as the basis of their inductive inferences. The present studies examine how children determine which category-based inductive inferences are warranted and which are unwarranted. Preschool and elementary school children learned various facts (e.g., “This apple has pectin inside”) and reported whether they thought ...
