Hi all,<br><br>I am simulating NCAT voxelized phantom and I am using interfile format for attenuation and activity.<br>I would like to know when we fixe the activity (in the file activity_range.dat), if the activity values are per pixel or per cm3.
<br>If I take the example in the Gate Users Manual :<br><br>| # set the number of subdivisions<br>| 6<br>| # define the intervals ex. [200,210] and attach a correlated activity: 1. Bq in this example<br>| 200 210 1.
<br>| 211 220 3.<br>| 221 230 5.<br>| 231 240 10.<br>| 241 250 20.<br>| 251 255 40.<br><br><br>The value 1. Bq is per pixel or per cm3 (or other) ??<br><br>Many thanks.
<br>Simon<br>
