摘要：
This paper deals with a reconstruction problem in magnetic resonance imaging where the Fourier transform of the sought-for object can't be obtained in the vicinity of a cone-shaped surface. This leads to streak-shaped artifacts in the sagittal views of the object. We describe a method for reducing theses artifacts by analytical continuation. We present numerical results for a toy object.
