In the past decades different methods based on magnetic resonance imaging (MRI) and positron emission tomography (PET) have been developed to image a variety of hemodynamic parameters in tissue. However, simultaneous high resolution imaging of oxyand deoxyhemoglobin is not yet possible in clinical practices with millimeter accuracy. Nearinfrared Spectroscopy (NIRS) is a well established techniq...

The 2D Image Data to visualize in the MRI images which never give the actual feel of how the internal parts would exactly look like. This project presents method for 3D image reconstruction, which is one of the most attractive avenues in Computed tomography (CT) and Magnetic Resonance Imaging (MRI) are modern and valuable diagnostic methods in a wide range of medical applications. Segmentation ...

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...

Magnetic Resonance Imaging (MRI) is a versatile imaging technique that allows probing of the various properties of the soft-tissue within the body of living organisms and has been widely used for diagnostic as well as research purposes. MRI has been very useful for studying the brain as it provides an exceptional ability to study structural, functional and dynamic properties in a non-invasive f...

hydrocephalus is a common finding in patient with extensive intracranial pathology. this finding may have obvious cause or even happened by a subtle abnormality. some of the normal looking ventricles are really hydrocephalus when compare with previous images and some are due to nph. communicating and non-communicating hydrocephalus should be separated to divided pathologic causes. this session ...

OBJECTIVE Although conventional radiography is used to assess osteoarthritis in a clinical setting, it has limitations, including an inability to stage early cartilage degeneration. There is a growing interest in using quantitative magnetic resonance imaging to identify degenerative changes in articular cartilage, including the large multicentered study, the Osteoarthritis Initiative (OAI). The...
