Susceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. SWI uses a fully flow compensated, long echo, gradient recalled echo (GRE) pulse sequence to acquire images.
COSMOS assumes a model-free susceptibility distribution and keeps full fidelity to the measured data. This method has been validated extensively in in vitro, ex vivo and phantom experiments. Quantitative susceptibility maps obtained from in vivo human brain imaging also showed high degree of agreement with previous knowledge about brain anatomy ...
FreeSurfer interoperates easily with the FMRIB Software Library (FSL), a comprehensive library for image analysis written by the Functional MRI of the Brain (FMRIB) group at Oxford, UK. The functional activation results obtained using either the FreeSurfer Functional Analysis Stream (FS-FAST) or the FSL tools can be overlaid onto inflated ...
3D Slicer Extensible, free open source multi-purpose software for visualization and analysis. Amira 3D visualization and analysis software; Analysis of Functional NeuroImages (AFNI) Analyze developed by the Biomedical Imaging Resource (BIR) at Mayo Clinic. Brain Image Analysis Package; CamBA; Caret Van Essen Lab, Washington University in St. Louis
CONN preprocessing pipeline includes steps designed to estimate and correct effects derived from subject motion within the scanner (realignment), correct spatial distortions due to inhomogeneities in the magnetic field (susceptibility distortion correction), correct for temporal misalignment across slices (slice timing correction), identify potential outlier images within each scanning session ...
Analysis of Functional NeuroImages (AFNI) is an open-source environment for processing and displaying functional MRI data—a technique for mapping human brain activity. AFNI is an agglomeration of programs that can be used interactively or flexibly assembled for batch processing using shell script .
Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...
Harmonic phase (HARP) algorithm [1] is a medical image analysis technique capable of extracting and processing motion information from tagged magnetic resonance image (MRI) sequences. It was initially developed by N. F. Osman and J. L. Prince at the Image Analysis and Communications Laboratory at Johns Hopkins University. The method uses ...
