CSX/IMAX and DSX Software

CSX/IMAX Release 3

September 8, 2005 - csx3 and imax3 have been released for Sun Sparc Solaris 8/9/10 systems and MacOSX systems. Following are the important features:

• GE Signa 5.x through 9.x (previous support only to 8.x)
• Philips (SDAT)
• Siemens (RDA) - new!
• Varian (VNMR)
• Other formats supported by Custom Import Tool
• Time domain or Frequency Domain Data supported - new!

• Single Voxel
• Multi-channel support - new! (but not yet for all file formats)
• 1D MRSI
• 2D MRSI
• Multi-slice 2D MRSI (all slices processed simultaneously - new!)
• 3D MRSI – new!
• Improved time-domain processing, options for water and lipid suppression
• Improved susceptibility corrections for MRSI
• Full support for 3D MRSI, including filtering, voxel shifting and phase correction in all 3 dimensions

Description of the Software

The CSX program was developed for the display and analysis of in vivo spectroscopy and spectroscopic imaging data sets. The program was initially developed in the OpenWindows environment of Sun Microsystems SunOS 4.x on Sparc computers. This code has also been compiled for Silicon Graphics IRIX6 system. The second generation of CSX (csx2) has been built for Sun UltraSparc Solaris 2.x and Linux systems. The latest version, csx3 has been built for Sun UltraSparc Solaris 2.x and MacOSX systems.

A new program named DSX, based on the CSX processing and analysis code but with a new GUI has been developed and built for use on x86 Windows (and eventually Linux) systems. It combines the functionality of CSX and IMAX. Use the DSX link for more information.

CSX supports all commonly used spectroscopy processing, display and analysis functions, and are particularly optimized for processing of spectroscopic imaging (SI) data. The plotting of spectra and results is supported on Postscript compatible printers. Currently, the program processes single voxel, 1D or 2D SI files, single or multislice. 3D SI is not currently supported. File formats of the following systems are supported: General Electric SIGNA (3.X, 4.X, 5.X and LX spectroscopy files ("N", "G", or "P" files; PROBE files)), General Electric Omega, Bruker DISNMR files (Aspect series), NMR1, SMIS (.mrd) and Philips  (.sdat). In addition, a general import tool allows the import of data files in other formats (e.g. ASCII, short integer or integer, floating point or "double", real or complex, any header offset or matrix size).

IMAX is an image display program, primarily intended for use in conjunction with csx. It includes facilities for the overlay of images with MRSI "grids" and "point-and-click" selection of spectra from regions of interest. It also allows region of interest measurements to be performed and combinations (add, subtract, logical combinations) of images to be calculated. The following file formats are supported: General Electric SIGNA (3.X, 4.X or 5.X image files), DICOM, and SMIS (.sur). In addition, a general import tool allows the import of data files in other formats (e.g. ASCII, short integer or integer, floating point or "double", any header offset or matrix size).
