By analyzing the effect of laser power input and the size of laser head on the curative effect of thermotherapy, some suggestions useful for tumour clinical treatment were proposed and discussed.
The artificial models can substitute for real tissues when their electrical and heating characteristics are closely similar, so the models could simulate bone tumors when heating.
Using this model, the 2D- SAR patterns were calculated, and different simulated results using a variety of electrode diameters were compared with the experimental data of the muscle-equivalent phantom.
Quercetin completely inhibited the synthesis and intracellular accumulation of 70-kD heat shock protein (HSP70) in response to hyperthermia or to treatment with sodium arsenite, whereas dihydroquercetin in the same or higher doses had no such effect.
This review compares high- and lowenergy transurethral microwave thermotherapy (TUMT) and transurethral needle ablation (TUNA) of the prostate with TURP in clinical efficacy and safety.
This review article discusses microwave thermotherapy as such an option and reports the long-term experience with the CoreTherm (CoreTherm Operations AB, Sweden) device.
Quasi-stationary-state electric field model was used to establish a group of finite-element analysis functions for the radio-frequency capacitive hyperthermia system. Using this model, the 2D- SAR patterns were calculated, and different simulated results using a variety of electrode diameters were compared with the experimental data of the muscle-equivalent phantom. Clinical attentions and applications were discussed.
A new technique was postulated to measure the space-dependent conductivety( K ), blood perfusion rate( W b), metabolic rate( q m), and thermal diffusivity ( α ) in Pennes' bioheat equation, thus overcomes the shortcoming of classical approaches , in which only the constant parameters( K,W b, α ) but q m could be obtained. The over-determined equations were solved by using Householder's transformation. In order to noninvasively measure the subcutaneous temperature, the variational principl...
An insulated, water cooled dipole radiating in a biological tissue was analyzed with a theoretical electro magnetic model. The temperature distribution was calculated, taking intoaccount the effect of the water flowing inside the applicator, and result compared with that of no water cooled radiating dipole. The numerical results calculated were comformed with those of equivalent muscle phantom experiment. It was shown that, the temperature distribution would be improved with the increase of therapy dept...
