Reducing radiation dose and enhancing imaging quality of 4DCT for radiation therapy using iterative reconstruction algorithms
Purpose Four-dimensional computed tomography (CT) images are typically used to quantify the necessary internal target volumes for thoracic and abdominal tumors. However, 4-dimensional CT is typically associated with excessive imaging dose to patients and the situation is exacerbated when using repeat 4-dimensional CT imaging on a weekly or daily basis throughout fractionated therapy. The aim of...
متن کاملRadiation dose reduction with hybrid iterative reconstruction for pediatric CT.
PURPOSE To assess image quality and radiation dose reduction with hybrid iterative reconstruction of pediatric chest and abdominal computed tomographic (CT) data compared with conventional filtered back projection (FBP). MATERIALS AND METHODS A total of 234 patients (median age, 12 years; age range, 6 weeks to 18 years) underwent chest and abdominal CT in this institutional review board-appro...
متن کاملIterative reconstruction technique for reducing body radiation dose at CT: feasibility study.
OBJECTIVE The purpose of this study was to evaluate the image noise, low-contrast resolution, image quality, and spatial resolution of adaptive statistical iterative reconstruction in low-dose body CT. MATERIALS AND METHODS Adaptive statistical iterative reconstruction was used to scan the American College of Radiology phantom at the American College of Radiology reference value and at one-ha...
متن کاملPerformance evaluation of iterative reconstruction algorithms for achieving CT radiation dose reduction — a phantom study
The purpose of this study was to characterize image quality and dose performance with GE CT iterative reconstruction techniques, adaptive statistical iterative recontruction (ASiR), and model-based iterative reconstruction (MBIR), over a range of typical to low-dose intervals using the Catphan 600 and the anthropomorphic Kyoto Kagaku abdomen phantoms. The scope of the project was to quantitativ...
متن کاملPhantom study on effect of advanced modeled iterative reconstruction on image quality and radiation dose
OBJECTIVE: The purpose of the current study was to evaluate the effect of an iterative reconstruction algorithm named advanced modeled iterative reconstruction (ADMIRE) on improving image quality and reducing the radiation dose. MATERIALS AND METHODS: The Catphan phantom (Phantom Lab, USA) was scanned on a SOMATOM Force CT scanner (Siemens Healthcare, Forchheim, Germany) with different exposure...
