| Abstract:: |
| Objective To study and compare several clinical used inhomogeneity correction methods. Methods The accuracy and speed of various inhomogeneity correction methods were tested by a clinical patient model. Results Although ETAR method considered more factors and consumed more time than Batho method, the accuracy of ETAR did not increase rapidly. Conclusions A new developed mixed Batho correction method could be applied in clinic to replace the ETAR method. |
