  How to determine the hard pulse width

  September 27, 2021 Blog

  How to determine the hard pulse width Due to the size of the RF coil and the power of the RF amplifier, the pulse energy required to excite the sample is also different. The pulse energy is determined by the pulse amplitude and the pulse width. Therefore,changing the hard pulse width is essentially changing the hard pulse energy. The most common ones in the pulse sequence ...
