Nonlinear filtering for CT radiation dose reduction
Nonlinear bilateral filters (BF) deliver a fine blend of computational simplicity and blurfree denoising. However, little is known about their nature, noise-suppressing properties, and optimal choices of filter parameters. Our study is meant to fill this gap—explaining the underlying mechanism of bilateral filtering and providing the methodology for optimal filter selection. Practical applicati...
متن کاملImproving abdomen tumor low-dose CT images using a fast dictionary learning based processing.
In abdomen computed tomography (CT), repeated radiation exposures are often inevitable for cancer patients who receive surgery or radiotherapy guided by CT images. Low-dose scans should thus be considered in order to avoid the harm of accumulative x-ray radiation. This work is aimed at improving abdomen tumor CT images from low-dose scans by using a fast dictionary learning (DL) based processin...
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 کاملThyroid dose and dose reduction method from CT scan of head and neck
Introduction: Computed tomography (CT) consists of 11% of all imaging methods, but accounts for approximately 67% of radiation exposure due to diagnostic cases. More than one-third of all CT scans are done in the head and neck area. The thyroid gland is irradiated during CT head and neck. According to studies, this gland has the highest levels of radiation-induced cancer, and i...
متن کاملRadiation Dose Reduction in Paranasal Sinus CT
Objectives. To (1) compare the radiation dose of low-dose computed tomography (CT) to that of standard-dose CT, (2) determine the minimum optimal radiation dose for use in patients who need endoscopic sinus surgery, and (3) assess the reliability of iterative model reconstruction. Study Design. Prospective single-institution study. Setting. Tertiary care center. Subjects and Methods. We recruit...
