Radiation 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 کاملImage Optimization and reduction of radiation dose in CT of the paranasal sinuses
Introduction: Since demand for computed tomography (CT) examinations is growing, patients are exposed more frequently to ionizing radiation. To reduce the dose delivered to patients in each scan, CT technologists can change the image acquisition parameters. However, this reduces image quality. Present study aimed to optimize and reduce radiation dose in a CT of the paranasal si...
متن کاملNonlinear 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 Techniques in the Workplace
The principal objective of radiation protection is to ensure that the dose received by any individual does not exceed the applicable M.P.D. values.We will discuss in this paper the presents recommendations and technical information related to the design and installation of structural shielding with taking into account the concept of Maximum Permissible Dose equivalent (MPDl as expressed and ...
متن کاملRadiation dose reduction in medical x-ray CT via Fourier-based iterative reconstruction.
PURPOSE A Fourier-based iterative reconstruction technique, termed Equally Sloped Tomography (EST), is developed in conjunction with advanced mathematical regularization to investigate radiation dose reduction in x-ray CT. The method is experimentally implemented on fan-beam CT and evaluated as a function of imaging dose on a series of image quality phantoms and anonymous pediatric patient data...
