WebMar 1, 2012 · Fan beam collimators are a special type of converging collimator with the holes focusing toward a focal line parallel to the axis of rotation of the camera ( 1 ). For optimization of collimator design, photon interactions in γ-camera collimators have been simulated by the Monte Carlo N-particle code (MCNP5) ( 2 – 4 ). WebDistance-driven projection is not implemented in stock MATLAB. For forward projection, there is the fanbeam () and radon () command, depending on what geometry you're looking for. I don't consider fanbeam to be very good. It exhibits nonlinear behavior, as of R2013a, see here for details.
