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 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...
متن کاملCT radiation dose reduction by modifying primary factors.
Given the steep trajectory of evolution in multidetector CT technology and its complexity, dose reduction efforts require knowledge of interplay between CT scanning parameters and their impact on radiation dose and image quality in CT examinations. We describe the effects of modifying primary scanning factors such as tube current, tube potential, and pitch factor (applicable to helical CT scann...
متن کاملWe can do better than effective dose for estimating or comparing low-dose radiation risks.
The effective dose concept was designed to compare the generic risks of exposure to different radiation fields. More commonly these days, it is used to estimate or compare radiation-induced cancer risks. For various reasons, effective dose represents flawed science: for instance, the tissue-specific weighting factors used to calculate effective dose are a subjective mix of different endpoints; ...
متن کاملRadiation dose reduction at multidetector CT with adaptive statistical iterative reconstruction for evaluation of urolithiasis: how low can we go?
PURPOSE To evaluate the performance of computed tomographic (CT) examinations at 80 and 100 kV with tube current-time products of 75-150 mA and the effect of adaptive statistical iterative reconstruction (ASIR) on CT image quality in patients with urinary stone disease. MATERIALS AND METHODS In this HIPAA-compliant institutional review board-approved study, verbal consent for prospective low-...
