Description
Nuclear Magnetic Resonance (NMR) techniques have been evolving, and are present in various sectors of society such as medicine, industry and agriculture. However, according to a review by Centro de Imagens e Espectroscopia por Ressonância Magnética (CIERMag), although they are practical to use in most applications, current NMR commercial equipment are restricted for modifications, and do not allow new pulse sequences, or pulse shapes - i.e adiabatic pulses - to be introduced in an easy way. In an attempt to solve these problems, the project ToRM-15 (Magnetic Resonance Tomography 1.5T) began to be developed. It allows the creation of a Digital Magnetic Resonance Spectrometer (DMRS) based on reconfigurable hardware powered by Field-Programmable Gate Array (FPGA). CIERMag has also developed software that allows the experiment planning and control, based on the Python Magnetic Resonance Framework (PyMR), and that uses the proprietary F - Language to develop pulse sequences. In this study NMR Methods for DMRS calibration such as: spectrometer resonance frequency adjustment, receiver gain adjustment, and the flip angle calibration were developed. Besides that, the pure water T2 value was measured using CPMG and is in accordance with the literature T2 = 2.045 seconds.
