Systems and handheld probes for non-invasive real-time magnetic resonance analysis of body tissues

摘要

The system for non-invasive analysis of tissue includes non-ferromagnetic handheld probes 15 that distinguish between nerve, muscle and blood. The magnetic field generator in the probe generates a magnetic field that is uniform and time-varying in the volume of tissue, receives RF excitation signals in a specific frequency range associated with the magnetic field strength, And an induction coil 19 for generating excitation signals magnetizing the tissue flakes, whereby only the living tissue of each flake responds to nuclear spin echo signals. The control unit generates a time pattern of excitation signals and extracts data representative of nucleus spin echo signals from living tissue to determine relaxation curves with time constants (T1, T2) and to perform statistical processing of relaxation curves Determine the type of tissue excited by the probe.
