Why SetTruncationCorrection(0.4) is not useful? #584

Closed xem123 closed 5 months ago

xem123 commented 5 months ago

image I want to perform truncation correction on projection data, but why does the CT data obtained after using this function have no effect?

"I tried three parameters: 0, 0.2, and 1, but why is the effect of CT reconstruction exactly the same for all of them? Where can I find the source code for this function?"

image SetHannCutFrequency(0.46) and SetHannCutFrequencyY(0.46) can work effectively, but SetTruncationCorrection(0.8) doesn't have any effect.

Not an issue, please use the mailing list to clarify your question, e.g. by showing an example. Truncation correction has an effect if your projections are truncated.
