The problems of magnetic resonance imaging (MRI) of objects having a very wide spectrum of the nuclear magnetic resonance, where signals from all its lines are difficult to detect, have been investigated. It is proposed to carry out MRI using frequency-selective pulses. A method for setting optimally the pulse parameters and the start time of induction signal detection is described. The calculation results are compared with the MRI data obtained for a fluorocarbon compound.
This paper presents a method for optimizing the parameters of the scanning pulse sequences for MRI in relation to objects with a wide NMR spectrum. In this case, a broadband excitation of the spin system is difficult because of hardware limitations. It is proposed to apply the selective excitation, the optimum parameters of which are calculated by an algorithm that uses information concerning the NMR spectrum. The method is especially useful for 19F MRI of fluorocarbons.
