A novel coronavirus named COVID-19 has spread speedily and triggered a worldwide outbreak of respiratory illness. Early diagnosis is always crucial for pandemic control. Compared to RT-PCR, chest computed tomography (CT) imaging the more consistent, concrete, prompt method identify patients. For clinical diagnostics, information received from scans critical. So there need develop an image analy...

Introduction In CT imaging, metallic implants inside the tissues cause metal artifact that reduce the quality of image for diagnosis. In order to reduce the effect of this artifact, a new method with more appropriate results has been presented in this research work. Materials and Methods The presented method comprised of following steps: a) image enhancement and metal areas extraction, b) sinog...

Introduction: Various computer assisted medical procedures such as dental implant, orthodontic planning, face, jaw and cosmetic surgeries require automatic quantification and volumetric visualization of teeth. In this regard, segmentation is a major step. Material and Methods: In this paper, inspired by our previous experiences and considering the anatomical knowledge of teeth and jaws, we prop...

OBJECTIVE Clip artifacts limit the visualization of intracranial structures in CT scans from patients after aneurysmal clipping with cobalt alloy clips. This study is to analyze the parameters influencing the degree of clip artifacts. METHODS Postoperative CT scans of 60 patients with straight cobalt alloy-clipped aneurysms were analyzed for the maximal diameter of white artifacts and the ang...

OBJECTIVES In this study, we aimed to describe the characteristics of portal vein tumor thrombosis (PVTT), complicating hepatocellular carcinoma (HCC) in contrast-enhanced FDG PET/CT scan. METHODS In this retrospective study, 9 HCC patients with FDG-avid PVTT were diagnosed by contrast-enhanced fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT), which is a combin...

introduction: this study was conducted to determine the pattern of maxillofacial fractures in three age groups of adults, adolescents, and children, using ct scan images. methods: in this cross-sectional study, ct scan images of 230 patients with maxillofacial trauma during one year were examined in terms of the number and site of fractures. the patients were divided into three age groups, chil...

109 All Rights Reserved © 2012 IJARCSEE Abstract: With rapid development of technology in biomedical image processing, classification of tissues of human body is very challenging task as it requires very accurate results without any misclassification. By making use of this technology along with neural network; a hybrid technique has been proposed for classification of Brain CT-Scan images. This...

A novel approach for detection of cancerous cells from Lungs CT scan images is proposed in this paper. Locating lung cancer at an early stage is a challenging task since there are few or no symptoms in this stage of the disease and majority of the cases are diagnosed in the later stages of the disease. Treating cancer in the early stages can provide more treatment options, less invasive surgery...
