| 英文摘要 | The magnetic field variation is a critical factor affecting the accuracy of temperature measurement in MRT. In this study, a 5-channel B0-shim coil was constructed for small animal temperature mapping in the MRI guided high intensity focused ultrasound (HIFU) at 3T. Firstly, the shimming ability was evaluated by the phantom study with a result that the standard deviation (STD) value of the offset magnetic field has reduced to 69% after currents optimized. Secondly, the relationship between T2* and SNR improvement has been studied. The results demonstrate that the temperature measurement accuracy is improved by 8% with the local multiple B0-shim coils. |
