Title: METHOD AND DEVICE FOR GENERATING A NUCLEAR MAGNETIC RESONANCE SPECTRUM OF NUCLEAR SPIN MOMENTS OF A SAMPLE
Abstract:
The invention relates to a method for generating a nuclear magnetic resonance spectrum (4) of nuclear spin moments (6) of a sample (8), comprising a static magnetic field (B) permeating the sample (8), and a detection spin moment (16) with a detection region (18) surrounding the latter, said detection region extending at least partly into the sample (8), and also an antenna element (22) for radiating in frequency pulses (F) for influencing the nuclear spin moments (6) and radio-frequency pulses (H) for influencing the detection spin moment (16), wherein a polarization step (42) involves polarizing at least one portion of the nuclear spin moments (6) along the magnetic field (B) to form a longitudinal magnetization (Mz), wherein a transfer step (44) involves converting the longitudinal magnetization (Mz) into a transverse magnetization (Mxy) by radiating in a frequency pulse (F) with a 90° flip angle, wherein a detection step (46) involves radiating in a sequence (S) of radio-frequency pulses (H) onto the detection spin moment (16) and subsequently detecting a signal (32') of the transverse magnetization (Mxy) present in the detection region (18) and storing said signal as detection result (48) in a list (50), wherein the detection step is carried out a number of times repeatedly in succession, wherein the polarization step (42) and the transfer step (44) and also the detection steps (46) are carried out repeatedly until a predefined number of repetitions (N) is reached, wherein a new list (50) with detection results (48) is generated with each repetition (N), and wherein an evaluation step (54) involves jointly evaluating the detection results (48) of the lists (50) across all repetitions (N).
