In clinic,therapeutic methods including photo-coagulation,radiotherapy using application,charged particle shot,local excision of the tumor,thermotherapy from pupil,chems immunotherapy have been carried out widely in our country,in which especially about its genneral treatment and the technique of tumor local excision and its enquipment refreshment.
AC magnetic field induction heating device is the key device of tumor thermotherapy,which is the most difficult monitoring and controlling middle and high frequency strong magnetic field.
The technique of thermotherapy of tumors has been widely adopted in clinical treatments. But the efficiency is not so ideal in treating the tumor tissues growing in the depth of the body, because of the difficulties in transmission and concentration of heat energy.And another problem to be resolved in tumor thermotherapy is to measure the temperature of tumor tissues being treated with thermotherapy exactly and rapidly. The difficulties in thermo dosage control aff...
AC magnetic field induction heating device is the key device of tumor thermotherapy,which is the most difficult monitoring and controlling middle and high frequency strong magnetic field.This paper introduces that it can detect the magnetic and temperature at the real time by using supervision system and embedded frontend machine and PC,and also can control the intensity of magnetic field,PC can display,analyze and deposit magnetic field and temperature.The experiment indicates that this system ...
With the sulfate as the materials and NaOH as precipitator, Mn_ 0.4 Zn_ 0.6 Fe_2O_4 nanoparticles were produced,which are proved to be spinel Mn-Zn ferrite analyzed by X-ray diffraction(XRD). Their shapes are approximately global examined by transmission electron microscopy(TEM) and their average diameter is 50 nm measured with image analysis-system.The Curie temperature was measured and in vitro heating test in a alternating magnetic field was carried out.The results show that the Curie temperature is 105....
