It can be analysed by MATLAB, using the following commands: </div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="background-color: transparent;">fid = fopen ('[your output name]', 'r');</div><div style="background-color: transparent;">projection = fread (fid, 'uint16');</div><div

In both tools, once the image is selected, you must select the image type as 16-bit unsigned, little Endian.</div><div><br></div><div>Please have a look at the following links which direct you to the ImageJ and Amide web-sites, respectively:</div><div><br></div><div>ImageJ: http://rsbweb.nih.gov/ij/<br></div><div><br></div><div>Amide: http://amide.sourceforge.net/index.html</div><div><br></div><div>The '.hdr' file is also a header-file which contains GATE interfile-output information. Such a file will help you to identify .sin file specifications such as height, <span style="font-size: 10pt;">width</span><span style="font-size: 10pt;"> and
number of projection images (dim1, dim2 and dim3, respectively). </span></div><div><br></div><div>Good work,</div><div><br></div><div><font size="2" face="arial, helvetica, sans-serif"><b>Hojjat </b></font></div><div><br></div><div><font size="2"></font></div><div><u><br></u><br></div></div></body></html>
