The variation of optical parameters in subcutaneous implanted rat liver cancers during laser induced themlotherapy (HIT) have been investigated with the method of near infrared spectroscopy technology ( NIST). A mathematical model of tenrperature and optical parameters for diseased tissue has been established to guide LITT. The therapeutic effects are confirmed with postoperative pathologic. The experimental results show that NIRST is useful to achieve real - time monitoring iu LITT with monitoring the changes of the reduced scattering coefficients.
