Accurate segmentation of brain tumor plays a key role in the diagnosis of brain tumor. Preset and precise diagnosis of Magnetic Resonance Imaging (MRI) brain tumor is enormously significant for medical analysis. During the last years many methods have been proposed. In this research, a novel fuzzy approach has been proposed to classify a given MRI brain image as normal or cancer label and the i...

Centre for Medical Image Computing, University College London, London, UK In this work, we further validate a CT and attenuation map (μ-map) synthesis algorithm [1]. The CT synthesis method relies on a pre-acquired set of aligned MRI/CT pairs from multiple subjects. Each MRI from the database is non-rigidly registered to the target MRI. The CTs in the database are then mapped using the same tra...

High-resolution X-ray computed tomography (CT) has become an invaluable tool in battery research for its ability to probe phase distributions sealed samples. The Cartesian coordinates used describing the CT image stack are not appropriate understanding radial dependencies, like that seen bobbin-type batteries. most prominent of these batteries is alkaline Zn–MnO2, which dominates primary market...

Radiotherapy plays an increasingly important role in cancer treatment, and medical imaging plays an increasingly important role in radiotherapy. Magnetic resonance imaging (MRI) is poised to be a major component in the development towards more e ective radiotherapy treatments with fewer side e ects. This thesis attempts to contribute in realizing this potential. Radiotherapy planning requires s...

Two cases of meningeal sarcoidosis with unusual and misleading presentations are reported. In the first case, CT scan, angiographic, and MRI findings were indistinguishable from those of meningioma. CSF pleiocytosis may help in diagnosing sarcoid pseudo-meningioma. The second patient had transient focal deficits and pachymeningitis of the convexity. The transient deficits were probably of epile...

The atomic parity-violation (APV) parameter QW for a nucleus with n neutrons and z protons has been included in the list of pseudo-observables accessible with the codes TOPAZ0 and ZFITTER. In this way one can add the APV results in the LEP EWWG ‘global’ electroweak fits, checking the corresponding effect when added to the existing precision measurements. † Work supported by the European Union u...

Rasmussen's aneurysm is an inflammatory pseudo-aneurysmal dilatation of a branch of pulmonary artery adjacent to a tuberculous cavity. Life threatening massive hemoptysis from the rupture of a Rasmussen's aneurysm is an uncommon yet life threatening complication of cavitary tuberculosis (TB). We present a case of a young woman who presented with low-grade fever and hemoptysis. Computed tomograp...
