Radiation Doses from Computed tomography in Iraq
Radiation doses to Patient during CT scanner and the radiological risk are significant. Patient dose survey has been conducted toinvestigate the Iraq patient radiation dosesreceived in CT scanners in order to established reference dose levels. These doses are Entrance Surface Dose (ESD),computed tomography dose index(CTDI)), and dose length product (DLP). Two CT scanner were investigated in thi...
متن کاملRadiation doses to emergency department patients undergoing computed tomography.
OBJECTIVES Computed tomography (CT) use is increasing in the emergency department (ED). Many physicians are concerned about exposing patients to radiation from CT scanning, but estimates of radiation doses vary. This study's objective was to determine the radiation doses from CT scanning for common indications in a Canadian ED using modern multidetector CT scanners. METHODS We conducted a hea...
متن کاملEstimating the Radiation-Induced Cancer Risks in Pediatric Computed Tomography
Introduction One of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. Therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...
متن کاملRadiation Protection in Computed Tomography.
Radiation exposure from computed tomography (CT) examinations has long been a concern. As part of their education, CT technologists learn the fundamentals of radiation interactions, dose, risk, and protection. Modern CT systems have evolved to include dose optimization features. This article reviews the fundamentals of radiation dose and introduces new CT dose optimization techniques.
متن کامل[Radiation exposure in computed tomography].
The axial dose profile of various scans of different CTs was determined to obtain specification on radiation geometry by collimation. The dose was measured "free-in-air" by thermoluminescent dosimeters at the axis of rotation. Considerable differences between the various CTs were observed. The scans of different CTs had narrow and wide fields. It seems to be possible to reduce the energy transm...
