Portable System and probe for the analysis of Magnetic Resonance Imaging in real time non-invasive Body tissue

摘要

1. A non-invasive tissue analysis system is described, including a portable (15) non-ferrous detector that can distinguish nerves, muscles and blood vessels; The magnetic field source on the detector generates a uniform time invariant magnetic field in a tissue volume, and includes an induction coil (19), which receives RF excitation signal in a specific frequency range, which is related to the magnetic field strength and generates a vertical excitation signal. The direction of the magnetic field and the part of the magnetized living tissue whose depth and thickness are predetermined by the intensity of the magnetic field,Therefore, only the living tissue responds to the echo signal of nuclear spy in each slice; a control unit generates the time mode of excitation signal, and extracts the indicative data from the echo signal of nuclear spy in the living tissue to determine the relaxation curve with T1 time constant, T2, the relaxation curve was statistically processed to determine the tissue type excited by the detector.
