<p>Are you using the same dataset for your different reconstructions ?</p>

<div>Dear CASToR users <br>
</div>
<div>I used the castor3.0.1 to reconstruct a PET data of some cylindrical phantoms and I used different TOF_reso values and also non TOF case. But I found that the SNR value of the non TOF was bigger than the TOF cases of 400,300,200 ps ( with decreasing the
TOF value the SNR decreased) . Should I modify the TOF command in Cdh file to apply the TOF on the image quality? Did anyone face this issue?
