Dose Reduction Methods in Chest Computed Tomography
Introduction: Computed tomography is one of the most powerful tools for investigating thorax disease, because it shows progression of lung disease much clearer than chest radiography. Technical advances in CT scanners have led to some abilities for CT scanners such as coverage of larger volume, lower noise and ability for acquiring image in one respiratory phase. However, this will be accompani...
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 کاملBismuth-Silicon and Bismuth-Polyurethane Composite Shields for Breast Protection in Chest Computed Tomography Examinations
The article aims at constructing protective composite shields for breasts in chest computed tomography and investigating the effects of applying these new bismuth composites on dose and image quality. Polyurethane and silicon with 5% of bismuth were fabricated as a protective shield. At first, their efficiency in attenuating the X-ray beam was investigated by calculating the total attenuation c...
متن کاملPatient 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 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...
