Dear CASToR users and developers,</div>

<div style="font-family: Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
I've simulated a uniform phantom in GATE and exported the GATE data to CASToR for image reconstruction. During reconstruction, I've chosen only the true events and ran a reconstruction, with and without attenuation correction. Then I visualize the image using
ImageJ (see attached), but I do not understand why counts are appearing outside the phantom volume. Could anyone help me understand why this is happening here? Has anyone seen this before? Is it due to noise and/or scattering outside the phantom?</div>
