Patient dose and image quality in computed tomography.
The relation between radiation dose in neurologic computed tomography scanning and image quality is described. Three different sets of images were obtained at varying exposures and were quantitatively evaluated by a panel of neuroradiologists. Anatomic information in the image varied with exposure. The relation of image quality and dose conforms to previous theoretical results and suggests that...
متن کاملOptimization of Radiation Dose in Cranial Computed Tomography among Adults: Assessment of Radiation Dose against Image Quality
Introduction: The rapid use of computed tomography (CT) scan is of great concern, due to increase in patients’ dose. Optimization of CT protocol is a vital issue in dose reduction. This study aimed to optimize radiation dose in cranial CT and assess modifications in image quality under radiation dose reduction. Material and Methods: A poly(me...
متن کاملAssessing the image quality and eye lens dose reduction using bismuth shielding in computed tomography of brain
Background: Epidemiological studies show that computed tomography (CT) is one of the main sources of ionizing radiations. Shielding of radiosensitive organs is one of the dose reduction methods. This study aimed to assess the eye lens dose reduction and image quality resulting from the use of radio-protective bismuth shield in brain CT imaging. Methods: Bismut...
متن کاملDose and Image Quality Considerations in Computed Tomography
Title of thesis: DOSE AND IMAGE QUALITY CONSIDERATIONS IN COMPUTED TOMOGRAPHY Samir F Abboud, Master of Science, 2011 Thesis directed by: Professor Iacovos Kyprianou Department of Bioengineering The increased use of Computed Tomography as an imaging modality is of concern because of the growing body of evidence linking radiation exposure to cancer incidence. However, a framework does not yet ex...
متن کاملPatient-Specific Radiation Dose and Cancer Risk in Computed Tomography Examinations in Ondo, Nigeria
Introduction: The dose in computed tomography (CT) often approach or exceed the optimum levels, thereby increasing the probability of cancer induction. With wide application of this diagnostic test, it is expedient to determine the effective dose (ED) for each patient to estimate their cancer risk. This study was conducted to investigate the patient-specific dose (PSD) and cancer risk in CT exa...
