摘要：
We describe a technique to reduce truncation artifacts in chemical shift images by using boundary information available from anatomic images. In this approach, high spatial frequency components are extrapolated from the observed data by making use of the boundary information. This technique has been tested with simulations and phantom experiments. Results obtained show that the technique works very well. In this paper, we present the technical details of and results of computer simulations and phantom studies.
