Description
technical field [0001] The invention relates to the technical field of nuclear magnetic resonance medical detection, in particular to a portable non-invasive quantitative detection system of nuclear magnetic resonance organ elasticity. Background technique [0002] Elasticity is an important mechanical parameter of biological tissue, which characterizes the difficulty of tissue deformation under the action of mechanical external force. Changes in tissue elasticity are closely related to its physiological and pathological state, and thus normal and pathological tissues can be distinguished. At present, based on tissue elasticity, it has been actively applied in tumor diagnosis, grading and rehabilitation evaluation of liver fibrosis. In traditional medicine, doctors qualitatively judge tissue elasticity through palpation, and then diagnose lesions. The diagnostic results have large errors and are greatly affected by the operator's subjective influence. In recent years, non-...
