LCModel 腦物質定量分析軟體

LCModel是一套被廣泛使用的磁振頻譜分析軟體

The LCModel package isfor the automatic quantitation of in vivo proton MR spec tra. LCMgui isa graphical user interface for running LCModel with more con venience and lessknowledge of thismanual. LCMgui isprovided without charge for use with LCModel only.

 

 

LCMgui Graphical User Interface

The normal usage is to supply the time-domain data as a simple text file to LCModel. A possible alternative is the LCMgui graphical user interface:

  • Freely available for use with LCModel.

     
  • Simplified usage, often only with mouse clicks, in two steps:
    1. Select the data with the File Selector;
       
    2. Start LCModel (optionally checking and modifying any settings) in the Control Window.

     
  • Currently for the following single-voxel data:
    • Bruker ParaVision fid files (if necessary, converted by you to analog mode with Bruker's convdta).
       
    • GE 5.x Probe raw P-files and spectrum G-files.
       
    • GE Probe raw P-files, including (new) Signa 20 P-files. Also for P-files with multi-channel (phased-array) data.
       
    • Hitachi data: part of the Hitachi software; no need to purchase separately.
       
    • Philips SDAT & SPAR files.
       
    • Picker (later Marconi, now Philips) DUMP files.
       
    • Siemens *rda files transferred from the syngo PC console and Siemens raw files from the (old) Numaris-3 Unix console.
       
    • Toshiba rawData files and Version 7.xx (and later) DICOM files;
       
    • Varian fid files;
       
    • Other data types using your own conversion script.

     
  • Currently for the following MRSI data:
    • Bruker (analog mode), Philips, Siemens & Toshiba data, including interactive display, selection and analysis of full 2D slices or rectangular subsets. (Instructions in Sec. 3.6 of the LCModel Manual.)
       
    • Other data types using your own conversion script;
       
    • For GE MRSI (and single-voxel) data, Mary McLean's LCModel interface [MA McLean et al, Magn Reson Med 44, 401 (2000)] is integrated into GE's SAGE Research version (from SAGE Dev2002.1).
       

 

Features:

  • Fully automatic, non-interactive, operator-independent: time-domain data input, one-page summary output.
  • Fully developed, over 17 years, with spectra analyzed from a wide variety of scanners and field strengths at more than 500 sites.
