Novel protocols are presented for acquiring one- and two-dimensional relaxation time spectra from selected subvolumes of a macroscopically heterogeneous sample. Although the protocols are generally applicable, special emphasis is given to their implementation on low-cost, low-field bench-top relaxometers lacking pulse shaping or pulsed gradient facilities.
本文提出了一种从宏观不均匀样品的选定子体积中获取一维和二维弛豫时间谱的新方法。尽管这些方法通常是适用的,但特别强调了它们在缺乏脉冲整形或脉冲梯度设备的低成本、低场台式弛豫计上的实现。
