Abstract

The invention is applicable to the technical field of photothermal therapy, and provides a photothermal treatment method and system based on terahertz imaging, and an industrial personal computer. A terahertz spectrum and imaging information of an object to be treated are obtained by transmitting probe light and radiating terahertz waves to the object to be treated, processing the probe light and terahertz waves reflected by the object to be treated as digital signals and generating terahertz pulse signals and are analyzed, and a region to be treated of the object to be treated is identified; a photothermal reagent with preset dose is injected to the region to be treated; pulsed laser is radiated to the region to be treated, photothermal processing is performed and the terahertz spectrum and imaging information of the object to be treated are obtained simultaneously; the effect of photothermal processing is monitored and the parameters of the pulse laser and the value of the preset dose and the duration time of photothermal processing are adjusted according to the effect feedback, target recognition, image monitoring and treatment on the region to be treated can be achieved simultaneously, the synergistic effect is good and no external interference factors exist.

Description

technical field [0001] The invention belongs to the technical field of photothermal therapy, and in particular relates to a photothermal therapy method, system and industrial computer based on terahertz imaging. Background technique [0002] Photothermal therapy technology uses near-infrared light with strong tissue penetrating ability as the energy source, and uses nanomaterials with high photothermal conversion efficiency, good biocompatibility, and low toxicity as photothermal reagents. The tumor marker recognition group is modified on the surface, and the photothermal reagent is injected into the patient's body for tumor targeting recognition and enrichment, and heat is generated under the irradiation of an energy light source, so as to achieve the purpose of targeted destruction of tumor tissue and killing cancer cells . As an emerging treatment method, photothermal therapy technology has many advantages such as high targeting, fast treatment speed, less side effects, ...
