Abstract: Parallel imaging magnetic resonance reconstruction is performed with temporal sensitivity. Rather than estimate the coil sensitivity once for each coil of an array, the coil sensitivity at different times is estimated. The movement of the patient may result in different sensitivities at different times. By using the time varying sensitivity in iterative, self-consistent, non-linear parallel imaging, real-time imaging may be provided with stable artifacts in view of increasing SNR even with higher reduction factors (e.g., 4-6).

Abstract translation: 平行成像磁共振重建以时间灵敏度进行。 不是对阵列的每个线圈估计线圈灵敏度，而是估计不同时间的线圈灵敏度。 患者的运动可能导致不同时间的不同灵敏度。 通过在迭代，自相一致的非线性并行成像中使用时变灵敏度，考虑到即使具有较高的减少因子（例如，4-6）也增加了SNR，可以提供稳定的伪像。
