呼吸引起的动态场图的变化在大脑中进行了量化,并对幅度信号(生理噪声)的影响进行了研究。动态非共振校正允许减少T2* 加权功能成像中覆盖血氧水平依赖信号的信号波动。
Respiration induced dynamic field map changes in the brain are quantified and the influence on the magnitude signal (physiological noise) is investigated. Dynamic off‐resonance correction allows to reduce the signal fluctuations overlaying the blood oxygenation level dependent signal in T2* ‐weighted functional imaging.
