In common radiography, the images of all bodys' structures lying within the path of radiation overlap each other. Tomography separates the required image from the surrounding area. Preliminary mechanism of sectional radiography, called the longitudinal tomography, does enhance the quality of image, but because of the different velocity of unwanted images, lying nearer to or further from axis ce...

Millimeter-wave (MMW) imaging has a tangible prospect in concealed weapon detection for security checks. Typically, one-dimensional (1D) linear antenna array with mechanical scanning along perpendicular direction is employed MMW imaging. To achieve high-resolution imaging, the target under test needs to keep steady enough during process since slight movement can induce large phase variation sys...

This research was part of the Cyclops-Project1 at the Artificial Intelligence Institute of the University of Kaiserslautern. The aim of the Cyclops-System [VW96] is to provide a software workbench for the development of knowledgebased image understanding applications, particularly in the field of analysis of MRI-images. The Cyclops-System can act as an image-understanding expert system, which d...

Introduction: Bacterial meningitis is an acute infectious inflammation of the protective membranes covering the brain. Its early diagnosis is vital because of its high morbidity and mortality. It is mostly diagnosed by a gold standard diagnostic tool i.e. Cerebrospinal Fluid (CSF) analysis. However, it is sometimes difficult and or impossible to do this procedure and an alternative diagnostic t...

the incidence of multiple myeloma (mm) affecting the jaws is 30% and on rare occasions the oral involvement can be the first indication of the disease. authors report a case of mm in a 40-yearold woman who presented with a multilocular radiolucent lesion in the left mandible initially mistaken as an ameloblastoma. conventional radiographs revealed a multilocular lesion on the molar region. comp...

Introduction:In this study, ECG signals have been embedded into medical images to create a novel blind watermarking method. The embedding is done when the original image is compressed using the EZW algorithm. The extraction process is performed at the decompression time of the watermarked image. Materials and Methods: The multi-resolution watermarking with a secret key algorithm developed in th...

background: magnetic resonance imaging (mri) has long been considered a perfect imaging study for evaluation of shoulder pathologies despite occasional discrepancies between mr reports and arthroscopic findings. in this study we aim to evaluate impact of imaging center as an indicator of image quality on accuracy of mri reports in diagnosis of rotator cuff tendon pathologies. methods: we review...

MRI guided focused ultrasound is an emerging technique that uses acoustic energy to noninvasively treat intracranial disorders. At high frequencies, it can be used to raise tissue temperatures and ablate discrete brain targets with sub-millimeter accuracy. This application is currently under investigation for a broad range of clinical applications, including brain tumors, movement disorders, an...
