激光治癌的理论基础是激光与癌细胞物质的相互作用。癌细胞数量的增长律是N=N_(?)e~(at)(1)式中 N_0是时间 t 为0时的癌细胞数量,a 是癌细胞增殖系数,它与癌细胞的寿命和倍增周期有关。癌肿癌的体积倍增律是:V=V_0e~t/(?)(2)式中 V 是在 t 时刻癌肿瘤的体积,V_0是 t 为0时刻的体积,P 是倍增周期。癌细胞物质吸收激光能量产生热,使分子离解,发射荧光和磷光,短波长激光能量高,能激励电子,并通过光激励和光分解,引起光化反应;波长长的激光能量低,能加剧分子的振动,而产生热。因此,激光与癌物质的相互作用是比较复杂的,但大致可以从光、热、压力,电磁场等几个方面的作用加以研究。
The theoretical basis of laser cancer treatment is the interaction of laser and cancer cell material. (1) where N_0 is the number of cancer cells at time t = 0, a is the cancer cell proliferation coefficient, which is related to the life span and doubling of cancer cells Cycle related. The volume doubling law of cancer is: V = V_0e ~ t / (?) (2) where V is the volume of the cancer tumor at time t, V_0 is the volume of t at time 0, and P is the doubling period. Cancer cells absorb heat generated by the laser energy to dissociate molecules and emit fluorescence and phosphorescence. Short-wavelength laser energy is high, which can excite electrons and cause photochemical reactions through photo-excitation and photolysis. Low-energy laser light can exacerbate the effects of molecules The vibration, and generate heat. Therefore, the interaction between laser and cancer is more complicated, but it can be roughly studied from the aspects of light, heat, pressure and electromagnetic field.
