<p>HELLO</p>
<p><br>
</p>
<p>I calculated Intrinsic spatial resolution of the SPECT camera with a point source, positioned<br>
</p>
<div>at the top of detector , 2 mm from the crystal surface.THE FWHM of the point source was calculated 9.8 mm.but the real value of intrinsic spatial resolution is 3.5 mm.I change
<span>setSpresolution</span> in digitizer macro file but the FWHM do not vary <span class="tlid-translation translation" lang="en">
<span title="" class="alt-edited">Significant</span></span>.
<div>how can i modify spect head or digitizer macro file for receiving real results.
