Can ifanbeam use all the sinogram generated by fanbeam ?

Hi,
I'm using fanbeam and ifanbeam, and have just realized that ifanbeam does not use all the sinogram when reconstructing in 'FanCoverage' 'cycle' mode. I used fanbeam to compute the sinogram of an image with FanRotationIncrement = 1, got 360 projections, and realized that ifanbeam does not use at all projections 199 to 342. Setting the corresponding columns to zero does not change at all ifanbeam's output.
Is there a way to modify this behavior ? I would like to use all the data I have acquired, not throw away a third of it (in a noisy environment, there is no reason not to use this data).
I hope someone knows a workaround
