Steady-State Gradient-Echo Imaging,plied (Chap. 2). In many cases the problems of patient motion can be circumvented by applying ECG triggering and/or respiratory motion detection, but in cases of abdominal imaging, heavy arrythmia of the heart function, fast dynamic processes, or very ill and traumatized patients, very fast scanning is necessary.作者: eczema 時間: 2025-3-22 12:54

Magnetic Resonance Imaging: A Historical Introduction,wever, there is a time gap of almost thirty years between the discovery of nuclear magnetic resonance simultaneously and independently by Bloch [1] and by Purcell [2] in 1946 and the first imaging experiments in the 1970s by Lauterbur and by Damadian.作者: Feckless 時間: 2025-3-25 13:27
