CT Imaging

CT Imaging PDF Author: Alexander C. Mamourian
Publisher: Oxford University Press
ISBN: 0199782601
Category : Medical
Languages : en
Pages : 253

Book Description
After reading this book, imagers and CT technologists should better understand the capabilities of modern multidector CT scanners. Imagers and technologists must understand how their scanners operate in order to take advantage of new capabilities for optimizing protocols that minimize patient dose. In addition, the reader will be better prepared to recognize the pitfalls and artifacts that appear on CT imaging. Some of these are unfamiliar to most imagers and are the product of the large detector arrays offered on new CT scanners.

Status of Computed Tomography Dosimetry for Wide Cone Beam Scanners PDF Author: I. D. McLean
Publisher:
ISBN: 9789201206107
Category : Technology & Engineering
Languages : en
Pages : 39

Book Description
This publication supports an interim solution to the dosimetric problems caused by modern computed tomography (CT) equipment, particular with respect to the wide X ray beam angles increasing seen in clinical practice. It reviews the development of current CT dose formalisms up to the current International Electrotechnical Commission (IEC) methodologies and presents practical measurement guidance in the implementation of new dosimetric methods needed with wide beam CT. Additional items of discussions are current approaches of the American Association of Physicists in Medicine in the USA to CT dosimetry as well as calibration aspects of CT dosimetric instrumentation. A summary describes the present status of CT dosimetry and provides recommendations for future action.

Dose Optimization in Digital Radiography and Computed Tomography

Dose Optimization in Digital Radiography and Computed Tomography PDF Author: Euclid Seeram
Publisher: Springer Nature
ISBN: 3031228715
Category : Science
Languages : en
Pages : 110

Book Description
This book addresses radiation protection of patients having digital radiography and computed tomography (CT) examinations. The literature on radiation doses to patients from these two modalities have reported that the doses to patients are high. As a result, the radiology community has focused on methods and procedures to keep these doses as low as reasonably achievable (ALARA) without compromising the diagnostic image quality. This book outlines the motivation for dose optimization in radiology, identifies and describes the ICRP principle of optimization, outlines the factors affecting the dose in digital radiography and in CT, and identifies and describes strategies used in digital radiography and in CT for dose optimization. This book is intended for all those working in digital radiography and CT environments including radiological technologists, and radiographers, radiologists, biomedical engineering technologists, and student medical physicists. It is best used as a supplement to radiologic science textbooks, and in particular, radiation protection textbooks. Furthermore, this book lays the foundations for students and practitioners engaged in research on dose reduction and dose optimization in radiology. · Provides practical and useful methods for optimization of doses from digital radiography and CT · Describes the International Commission on Radiological Protection (ICRP) principle of optimization · Outlines the factors affecting the dose in digital radiography and in computed tomography
