ifanbeam and iradon

Hi, I tried to use ifanbeam to provide Ct images but when I use this:
D=600; dtheta = 2; dsensor=0.1 ;
[Farc,Fangles] = ifanbeam(R,D,'FanSensorSpacing',dsensor,'FanRotationIncrement',dtheta,'Interpolation','spline','OutputSize',256);
I got an unusual image but by iradon I=iradon(R,0:179,'spline',256); I got a right one(of course with artifact), dose any one know about it, it seems there is a relation between FanSensorSpacing and D, thanks for any hints and guide, thanks in advance.
regards
