Software
BioImage Suite
is an open source, multi-platform image analysis suite developed at Yale University. The Differential SPECT tool within this suite can be used to employ
ISAS BioImage Suite following the detailed instructions here.
MATLAB
refers to both the numerical computing environment and to its core programming
language. MATLAB is the platform on which SPM (see below) is implemented. ISAS has been thoroughly tested with MATLAB6p1.
Statistical Parametric Mapping (SPM)
is the analysis method used for ISAS. Developed at the Department of
Cognitive Neurology, London, UK, SPM is based on the
general linear model
(GLM), and has wide applications in neuroimaging analysis. ISAS has been thoroughly tested with SPM2.
Image J
is Java-based image processing software distributed by NIH.
Using the appropriate plugins we are able to convert raw reconstructed data (Picker) into Analyze format so they can be read under SPM.
Other features of this software include creating region of interests (ROI), image editing, stacking of related images (DICOM to Analyze) and more.
MRIcron
is a standalone program that complements SPM. MRIcron allows for
efficient viewing and exporting of brain images. In addition, it allows
identification of regions of interest (ROIs, e.g. lesions). Lastly, 3D
displays with overlays can be created for presentation purposes.
NOTE: MRIcro no longer exists, current version is: MRIcron
Rview
is an image registration and analysis tool, written by Dr. Colin
Studholme, that enables simple calculation of ictal-interictal SPECT
difference images coregistered with a MRI scan.
