Description
Summary
Convert Analyze data to the NRRD format which can be used in SCIRun networks.
Detailed Description
This module provides support for converting <ulink text="http://www.mrc-cbu.cam.ac.uk/Imaging/Common/analyze_fmt.shtml">Analyze</ulink> data to the <ulink text="http://teem.sourceforge.net/nrrd/index.html">NRRD</ulink> format which can be used in SCIRun networks. An important point is that this module is dependent on the Insight package, so both the Teem and Insight packages have to be enabled in the SCIRun build in order for the ImportNrrdFromAnalyze converter to work.
Some brief background information about the Analyze format will be helpful in understanding how to load data using the ImportNrrdFromAnalyze reader. For a detailed description of the Analyze format, please refer to the documentation pages for <ulink text="http://www.mrc-cbu.cam.ac.uk/Imaging/Common/analyze_fmt.shtml">Analyze</ulink>.
Analyze files contain volume data, often from MRI. The Analyze format includes two different files for each volume: a header (extension ".hdr") file and and image (extension ".img") file. All of the image data for a volume is contained in a single image file. Since these files come in pairs, the ImportNrrdFromAnalyze module requires the user to specify a ".hdr" file to read. Then the module looks for the corresponding ".img" file in the same directory as the ".hdr" file.
The ImportNrrdFromAnalyze module requires the user to specify a directory containing the data files. One or more Analyze files may be selected for processing. If the files are recognized as valid Analyze format, they are read in and converted to the NRRD format which can then be passed downstream to certain other SCIRun modules.
