ODIN Description

Free software framework for rapid prototyping of magnetic resonance imaging (MRI) sequences ODIN is a free and open source C++ software framework that will help you develop, simulate and run magnetic resonance sequences on different platforms.ODIN is:State-of-the-Art: Contemporary magnetic resonance imaging techniques are available, for example sequence modules for echo-planar imaging and spiral-imaging, parallel imaging with GRAPPA reconstruction, two-dimensional pulses and field-map-based distortion corrections.Easy-to-Use: All common steps, from compiling your sequence to plotting or simulating it, can be performed within a graphical user interface.Hardware Independent: ODIN runs on a variety of operating systems and scanners. Once you develop a sequence, it can be executed/simulated on very different hardware, ranging from a real-time sequence controller to your personal workstation. Truly Object-Oriented: Written in C++ with an object-oriented design, ODIN is very modular, flexible and requires very little code to write: The sequences that come with ODIN are easy to understand and modify. Supported Image/Data Formats:· ASCII· Ansoft HFSS ASCII· DICOM· GNU-Zip container for other formats· Iris3D binary data· JCAMP-DX data sets· JCAMP-DX image format· Matlab ascii 2D data matrix· MetaImage· NIFTI/ANALYZE, dialects: fsl· PNG image writer· Vista, dialects: common odin lipsia xlipsia· Visualization Toolkit· double raw data· float raw data· signed 16 bit raw data· signed 32 bit raw data· signed 8 bit raw data· unsigned 16 bit raw data· unsigned 32 bit raw data· unsigned 8 bit raw data· x-y positions of non-zeroes in ASCIINOTE: Installation instructions for Mac OS X can be found in the INSTALL.TXT file inside the archive. Here are some key features of "ODIN": · Plotting of the sequence timecourse in a graphical user interface. · Simulating the spin-physics of the sequence (Bloch-Torrey equations) using a virtual phantom to generate a virtual MR signal. System imperfections (eddy currents, B1 inhomogeneity, noise) can be switched on/off at will during the simulation. · Visualization of the k-space trajectory. · Calculation of gradient moments (k-space) and diffusion weighting. Requirements: · Xcode 2.4 or later · Fink 0.8.0 or later · Qt 4.1.0 or later What's New in This Release: New Features: · Auto-detecting number of cores for odinreco. · Added functor 'fmri' to odinreco (fMRI localizer). · Optimized trapezoidal gradint pulses. · Added filter 'detrend' to remove slow drift over time. · Added filter 'merge' to merge datasets into one. · Added filter 'usemask' and 'selfmask' to generate 1D array · using a mask. · Multi-threaded simulation of MR signal. API Changes: · SeqPulsar::set_rephased() now accepts an optional · argument to set the rephaser strength. Internal Changes: · New template class ThreadedLoop for parallelized loops.
