Streak artifact reduction
WebBackground: Myocardial computed tomography perfusion (CTP) using conventional single energy (SE) imaging is influenced by the presence of beam hardening artifacts (BHA), occasionally resembling perfusion defects and commonly observed at the left ventricular posterobasal wall (PB). We therefore sought to explore the ability of dual energy (DE) CTP … Web29 Apr 2024 · Recently, Xie et al. used a deep learning technique in reducing streak artifacts caused by sparse view sampling in a low-dose CT scan. They used an improved version of the GoogleNet (inception network) to reduce the streak artifacts in the CT images. Zhang et al. used the original U-net structure to correct several types of CT artifacts. They ...
