Great. Thanks Cesar. Do you have any notes on how to change the calibration?

Hi Stuart,

OK, I have seen what the issue is. I will sort this out by adjusting the fusion calibration, I have seen that this was FOV50 and PH collimator.

Just now my internet connection is too slow but I will be connecting again later on and will do it. I will let you know when I am done.

Best regards,

Cesar.

Hi guys, we just ran a CT/SPECT image set using the same offset (36mm). We used standard parameters, single bed position, and automatic recon. It looks like the z-registration is off by several mm and the x may be off a bit too. It is study 10210 from today if you want to log in to take a look to see if I did something wrong. The sample is still in the scanner if you want to make another run. Please let me know what we can do to get the registration better. Thanks.

Stuart
