when I use Projector class to project and fbp with an axial scan geometry, the reconstructed first slice and the last slice have a value-jump compared to the other slices...
When I try to set leap image volume parameters using an initialState.sct file, or when I set the parameters using setDefaultVolume(), I get a slight difference. Consider an image that...
Hi, when I use Projector class in leaptorch: proj = Projector(forward_project=False, use_static=True, use_gpu=True, gpu_device=device, batch_size=batchSize) f = proj(g) proj.leapct.fbp(g, f0) I found that f is in the order of 10^3,...
Hello Kyle, If i reduce pixel size, the MTF values are adnormal as shown in the graph below. What should I do? 
Hi Kyle, I tested FBP with my private head data, but found Moiré Pattern in the lower part near the bony area. Do you have any ideas, is it related...
Hi, I recently discovered a new gadget in the leap kit demo under demo_leapctype/d15_detector_deblur.py, and I’ve been exploring its potential with my own data. I’m really fascinated by the functionality,...
Hi Kyle Champley, Thanks a lot for this amazing toolkit. It is very convenient to use with Pytorch. However, I am facing an issue that my GPU memory always increases...
"pip install ." fails to link the leapct libraries resulting in a dll not found at runtime. Resolution is to manually link or copy library, and then the demos work....
Hi, Recently, I've been working on reconstructing multi-energy photon-counting CT data using LEAP. The reconstruction geometry is for a helical scan with a pitch of 10 mm. I noticed that...
I am trying to validate the accuracy of the SF projectors for a flat panel. I am attempting to replicate https://pmc.ncbi.nlm.nih.gov/articles/PMC2993760/ * which is cited as the reference for LEAPs...
