Abstract :
Three approaches for truncating the scan plane in diffraction tomography-based imaging are suggested and compared. The first and second approaches involve multiplication of a window to the scattered field before evaluating the spatial Fourier transform. The third method relies on an asymptotic end-point expansion of the Fourier integral
