Description

technical field [0001] The invention relates to a technology in the field of optical temperature measurement, in particular to a temperature measurement device integrated with multi-spectral and multi-optical technologies. Background technique [0002] Hyperthermia targeting the tumor site is one of the important means to inhibit tumor growth. Its basic principle is to use an external physical heat source to heat the target to increase the temperature of the tumor area, so as to achieve apoptosis of tumor cells without causing damage to normal tissues. therapeutic purposes. However, accurate and highly sensitive detection of the temperature change inside the target tissue during the temperature rising process is critical to improve the therapeutic effect. Traditional nuclear magnetic resonance detection technology can obtain high-resolution and high-contrast temperature rise images, but it takes a long time and is expensive, and this method is easily affected by tissue elec...
