INTEGRATED SOLUTIONS FOR NEUROSCIENCE Image conversion from DICOM to Analyze for Brainsight use Purpose: Some DICOM images lack the slice position information required for Brainsight to correctly load them in and construct volume data. These instructions are to explain the steps to convert images in DICOM format (that lack slice position information) into "Analyze" format images with the correct information allowing them to be used successfully in Brainsight. In addition to converting to the Analyze format, you may need to change the orientation of the images to transverse. This will be covered in the second section of this document. You require MRIcro (http://www.softpedia.com/get/Science-CAD/MRIcron.shtml) running on a Windows equipped computer. Converting from DICOM to Analyze Step 1: Move the DICOM images into a separate directory on the computer Step 2: Run MRIcro and select "Convert Foreign..." from the "Import" menu (see figure below) File Edit Header View ROI Overlay Etc Open foreign...

Slice Viewer [✓ Xbars Black & White I SquareI x1 I Step 3: Determine the number of DICOM slices in the directory to be converted, and enter the value in "Number of files" (see figure below). Enter other values as shown in the figure.

Do you wish to stack more than one DICOM/Genesis file into a single Analyze file? After conversion., check left and right orientation.

The software save the new data into the Analyze file. Analyze image data sets consist of 2 files. The header information, which contains the volume dimensions and other information, and the image data. The header file has an extension of “.hdr” while the raw image data has an extension of “.img” Both are required for Brainsight. Step 6: Copy the two files (.hdr” & “.img” files to the Brainsight workstation for use.
