Pathological changes in biological tissues usually cause changes in their microstructure. Since the second harmonic generation signal is highly sensitive to the symmetry change of the microstructure , SHGI can be used for the early diagnosis of diseases and the monitoring of aftertreatment in clinics.

生物组织的病变往往会引起微观结构的变化，而二次谐波信号对组织的结构对称性变化高度敏感，因此二次谐波成像对于某些疾病的早期诊断或术后治疗监测，具有很好的生物医学应用前景。
