Design and Fabrication Process of CT number Linearity and Homogeneity Phantom CT Scan
Introduction: One of the most valuable goals of phantoms, replacing with human goals in the field of research and quality control of diagnostic X-ray systems. There are various algorithms and methods for obtaining Homogeneity and CT number linearity for CT scan device. One of the most famous of these methods, the method is to use a uniform and homogeneous environment to comput...
متن کاملLung Lesions Biopsy in Children by Computed Tomography (CT) Fluoroscopy Guided Versus Conventional CT Scan Guided
Abstract Background Computed tomography (CT)-guided biopsy of the lung is a well-established method of diagnosis. The aim of this study was to determine the success rate of fluoroscopic CT (FCT) and conventional CT (CCT) in needle navigation biopsies from the lung lesions. Materials and Methods A total of 78 patients were prospectively enrolled to receive CT-guided biopsy with (group I, n=2...
متن کاملThe influence of misregistration between CT and SPECT images on the accuracy of CT-based attenuation correction of cardiac SPECT/CT imaging: Phantom and clinical studies
Introduction: Integration of single photon emission computed tomography (SPECT) and computed tomography (CT) scanners into SPECT/CT hybrid systems permit detection of coronary artery disease in myocardial perfusion imaging (MPI). Misregistration between CT and emission data can produce some errors in uptake value of SPECT images. The aim of this study was evaluate the influence...
متن کاملPercutaneous Transthoracic Lung Biopsy: Comparison Between C-Arm Cone-Beam CT and Conventional CT Guidance
BACKGROUND C-arm cone-beam computed tomography (CBCT) is a comparatively novel modality for guiding percutaneous transthoracic lung biopsies (PTLBs), and despite its potential advantages over conventional computed tomography (CCT), a head-to-head comparison of the two techniques has yet to be reported in the literature. This study aims to evaluate the diagnostic value and safety of CBCT-guided ...
